No heating? An easy fix using a switch on the motorised valve 

Hi mate, I’ve used your vids loads in the past - (Used one of your videos a few years ago when I had to replace this part in my system). Just fixing a dripping tap in my house and once again a vid from a few years ago showed me exactly what to do. Keep it up! Most valuable channel on RU-vid.

Thank you so much for this. I have a condo, and as the winter prep started, we found we had no heat. An electrician/plumber came in and fixed a problem with the thermostat, but there was minimal heat from the rad. I was then informed that I needed to change my zone valve and to bleed the system as I had an airlock. I contacted the folks who did the work and was looking at almost 1 grand of "work" to be shouldered by myself as it's indoor work, so I decided to do some research. Now, all I've done is flip the switch from Auto to Manual as Dereton30 indicated in the video, and taraaaaa! I've got sweet heat flowing at full blast. Nice little gift for the first snowstorm of 2023. THANK YOU!!!

Heating engineer visited this afternoon and replaced the 3 way valve so all is well now thank you. Your advise gave us a temporary fix which kept us and our children warm, so a big thank you.

Thank you so much for this video sir. My radiators weren’t getting hot no matter how much I turned the thermostat up, I even bled them but still no joy. Even had an engineer come out a few days ago and they didn’t fix the issue. So I decided to search RU-vid today for a possible solution and landed on your video. Now my radiators are working like a well oiled machine. Thank you so much, my family thanks you. God Bless.

Replaced a Sunvic MoMo valve for one of these Honeywell valves earlier in the year thanks to learning from your videos Al. The manual lever function is very useful. 👍👍

Good stuff Al! Our heating systems always conspire against us at the first sign of cold weather!

Thank you very much for your video. We had no heating, but did have hot water. I checked the thermostat and boiler without success. After watching this I put the valve into manual and everything is working now. I shall get a professional in to do a replacement repair, but am really thankful that we now have heating again.

Your a genius Al, I am warm again whilst working from home and the kids have one less thing to moan about when home schooling! Just wanted to say thanks, this fix hasn't lifted my spirits, I would love to buy you a pint one day 👍

Like everyone else, I want to thank you sir for this invaluable information- it’s certainly boosted my confidence. In the past I have tried moving these levers but did so with so much uncertainty and fear of blowing up the boiler or the whole house! However, after watching your video, it’s given me some reassurance and now I know it’s safe to do so. One other thing I noticed is that you’ve taken the time to provide answers to every single post and we salute you for this. What a gentleman- the world needs more people like you🤗

Thanks a lot mate, this video just saved me today, my home is now warm while we wait for an engineer to attend in the next couple of days, my RD1 kept cutting out after about 30 seconds, so I had no heating but had hot water, thanks a lot, hopefully it’s not too expensive to fix

I've had a couple of problems with things an have watched your videos an have fix my issues everytime thank you so much.

This is an excellent presentation which gave me the confidence to fix my motorised valve !! Many thanks for that. (particularly as my pension buys little these days)

Just want to give you a big thank you, we've had no heating upstairs for 2 weeks. This worked straight away👍 Also nice to see someone on RU-vid who speaks clear English, right to the point with no rock music in the background 😁. Can't thank you enough.

Genius! Thank you for your help with this and the Link for the part! All the very best to you!

What a lovely man and well explained. This was very helpful thank you

Hi Al Just to say thank you for this tip it's only easy when you know how thanks for sharing you knowledge top video.

Many thanks and keep posting more videos as I've followed you for years

Thanks, was trying to set to manual but it was not working...then I saw your video and realised I had to use the notch to fix it to manual...Thanks a bunch!!!

Thank you,saved me being with out heating all day.top man

Thanks for explaining for the layperson, great video!

Such a fantastic video, thank you. My valves lever has no springiness it just drops down.

great vid thanks that will save me a lot of money for an easy fix Could you do one for the main circulation pump change as well please

excellent explanation, thanks. I am about to do the powerhead replacement

My valve has broken altogether so need a heating engineer / plumber but I am glad watched your vid so I don’t get ripped off. I know what the problem is.

Thanks for a simple solution, am so glad that have heating with a young baby in the house was a bit worried. Was wondering if I can change the valve motor in situ by just switching mains electricity while I am working or do I need to take it off the T-junction

Super clear explanation! Turns out I've already subscribed to your channel

Saved me from a big bill or a cold Christmas. Thanks

Thanks so much. I did not realise how straitforward it is. They are trying to remove any self help and make us into helpless fools.

Thanks for the video, it answered the question I had brilliantly 👍🏻

Oh my god you rare such lifesaver thank you. My underfloor heating stopped working wasn't sure what happened to it. One push of lever job done. As easy as you described I'll still get it wrong. Can I keep it manual?

Clear and simple. Great video thanks.

Great video. Another fault of these valves is they turn the boiler on when the timer switch is off making the Orange wire live 240v. So if orange wire has 240v when everything off then swap the head.

great explanation very straight forward .. is the same problem if the no hot water coming only heating on ( any time I put hot water only from my boiler comes the heating on with it )

Thank you for this video. Very helpful.

Thank you. Your video really helped me last year. I replaced the head. But it looks like the motor has gone again just 14 months later. I have a hive system that controls this on and off around three times a day. I'm not sure it it's that causing motor burn out or if the physical valve is broken. Only 6 years old. But now third motor now.

Hi Derick, Great informative video as always and wondered if it's normal for my Danfloss casing to always stay warm even when the boiler is not on. Everything seems to be working ok and the motor is only about 18 months old with little useage

Thank god for someone like you Thanks so much

You’ve just helped us get warm again!! THANKS! Is there any chance that if I flick it back to auto it might work again...for a while? Wondering if it’s broken valve or just a bit cloggy?

Brilliant explanation and practical video . Thank you ! Just a question about drain down and refill ......do you keep the Three Port Valve locked over to the manual position when refilling the system or do you unlatch it ?

Excellent explanation and visual strip down.

Thanks very much, just got our heat going on a cold night

You are a God send my good man thanks for the video

Really helpful- thanks for uploading!

Like everyone here I want to say a big thank you. First time home owner and these kind of things can seem a bit daunting when you are novice! I am going to replace my boiler with a combi in a months time. Can I leave it in manual for a month?

Brilliant video, thanks! I put the switch into the “V” but doesn’t get heating back. If I manually hold it to the faaaar right the heating does come on only as long as I hold it there. Guessing I have to replace it?

Thanks mate, having a bit of bother so it’s sorted me out.

very good information thanks for that very useful video you have done

Hi - Thank you so much for this helpful video which really helped me out a while back.I was hoping you might be able to help with a quick question please…? I switched my heating off over Christmas and just returned home. I switched on the heating and water only to find that all my radiators were freezing. Tried resetting my Worcester Greenstar which didn’t work so I tried your valve fix. This enabled the bathroom radiator to come on fully (thank you!) but the others are still cold. Grateful for any advice kind sir!

Thanks for the video. I'm about to change the head on my 2 zone valve. Should I put the lever in manual (open) position before removing, or does it not matter as long as the new one goes on in the same position?

Top man and another great video. Cheers Al.

Brilliant Got our Hot Water going until we could get a Plumber out. Thanks.

hi, thanks for the great video. i recently had no heating in rads upstairs. i removed the motorized valve and manually opened the valve and the rads began to heat. is it ok to just leave the valve open even when the heating is off. thank you

Well done Al 👍👍👍👍

Excellent video !

Your videos are fantastic. I've had issues with my system - was limping before storm Eunice, then had pilot blown out in storm and getting it working properly since is a pig. Can't tell if boiler getting locked due to diverter or (new) diverter isn't receiving a signal from boiler. Ideas??

Great video, will this be the same issue for my hot water is heating up radiator? The heating is off but when my water heats up my rads seem to start getting warm.

Hi. Thanks for the video! Got the downstairs rads on now. I have 3 x two way valves (upstairs, water, downstairs). When the faulty downstairs valve is manually opened it continues to run the boiler rather than the boiler following the timer so I have to turn it off manually to stop it continually being on. One timer is for water and downstairs valves and other for upstairs valve. Would this be a valve motor issue or timer issue? The water valve still works. Thanks in advance

Hello, I've got two of these, I believe it is the two valve ones. Do I set both of these to manual? Or do I need only a certain one set to it. Thank you!

Brilliant. Many thanks.

Thanks for the video, what does this motor do? I'm trying to increase the water pressure to my hot taps and noticed the switch moves freely and when pushed to manual won't slowly move back to auto. I can move it to where I like and it stays there. Is this normal?

Hi I’ve got an old 1979 heating system Stelrad boiler. There doesn’t appear to be a motorised value fitted. And no room thermostat. I’ve change to a hive thermostat and still have the problem of no heating unless the hot water is on as well. Do you have any suggestions please? This is another great video and I’ve watched other when doing diy plumbing. Thanks chris

Thank you for the greet video! My heating is always on when hot water turns on even in the summer. Is this a 3 way valve issue too?

Hi, thanks for such an informative video. This has helped me enormously in tracing an issue with my central heating. May I ask you one question? I have a 2 way valve that controls the downstairs underfloor heating. Isn’t firing up the boiler - I’ve checked the switch and it correctly seems to have opened up with load. if I turn the load off it then has resistance, so I’m assuming that part of the valve has worked. Is there part of this valve that then signals the boiler to fire up? Thanks very much in advance!

Would a faulty 2-way valve, or an associated faulty motor, cause a loud bang when the central and/or hot water is sequenced either to run or stop? Also, I'm guessing that you can't attach the motor onto the valve upside down, or could you?

Thank you ...your a star.

Bless you! Thanks so much!

Can I run hot water take the body off as the manual leaver just lose if so which portion the value to open

Thanks for the video it worked

Great video thanks 👍

Thanks for the fantastic video. I’ve got no hot water unless the CH fires up. I have 2x 2-port valves beside the HW cylinder . One of them is warm to the touch so I’m guessing that is the one for HW. I went to set it to Manual to find it already jammed in manual (I can’t move it to auto). Is this still a motor box change? Thanks in advance!

Thank you so much for this. My three way valve was buzzing after the timer switched everything off and so I replaced the valve using your instructions to the T. I switched the old one to Manual before removing and put the new one to Manual before installing and then returning it to Auto. I now have a problem with the heating coming on with the hot water even though the heating is set to “Off”. I have checked the wiring and everything is in the right place. Any ideas, please?

Hello, thanks for the video. Ours has failed in stages, first no hot water but heating worked, then heating packed in, but we still have heating upstairs controlled by a separate thermostat. I have 3 motorised valves in the airing cupboard, one labelled ‘Up - upstairs I’m guessing - ‘D’ - downstairs and then one on top of a pipe feeding into the tank. I have moved the lever on the D - downstairs one to manual open. But the boiler still isn’t firing when selecting +1 hour for heating or hot water or both together. In fact when both together the thermostat just flashes and clicks on and off. We have Honeywell thermo and a logic 15 boiler. Any ideas? Should I switch all 3 boxes to manual open? Thanks in advance

Hi, great video. I've taken the cover off to see if the motor is opening/closing the valve, however I've waited a while after the hot water is on but can't see the motor close the valve. Should it open and close as soon as the boiler/hot water is turned on and off? Cheers

Great video and a total lifesaver! Quick question....I removed the square cover from the unit and the round cover off the motor to discover that the flywheel on the outside was spinning freely and making a weird noise! Its a 3 -way device. I had previously switched to "manual" due to lack of heating as you advised and it worked for a bit but then was a bit stop start - I'm guessing the unit is completely useless, does that sound the case? Cheers and keep up the good work!

Thanks for the excellent explanation of the motorised valve. My CENTER valve is making a continuous tapping noise. I moved the lever to manual. It made no sound when I moved it and had no resistance. The lever is down fully but will not clip into place. My central heating is set on at the controller and is working. My hot water is off at the controller but the water is hot. So i assume the valve is open. But the motor or something is tapping away. Any ideas?

Hi thanks for the wideo, When valve 3 port is set to central heating it is all the time a hot motor and there is a soft noise coming from it, this is good? How do I change to heating water everything is ok

Hi. Great vid. I have 2x valves, one for my central heating (which works fine and boiler fires). The other is for my kitchen UFH. This one turns on via my nest, but boiler doesn't fire, which is why I think the valve may be the issue. However, when I switch to manual as per the video, it doesn't fire the boiler - should it? Would you recommend changing just the head unit, or the valve also? (mine is 2 way valve)

Hi. Thanks for your video! I have two of these controlling an annex. They have both gone at the same time! Been eight years. The lever on one has no resistance at all and the other one keeps opening and closes when calling for heat (springs back and forth between open and closed making a noise when doing so). Basically both installed at same time but have both failed in different ways. Please could you comment on the possible problem? I would like to just open both up and control with TVR's if possible.? Jammed the one that springs back and forth in place (as it kept slipping back to auto) but the other has no resistance at all i.e. just slides back and forth between auto and open with no resistance. Any help appreciated! Model is HONEYWELL V4073.

Thank you for this video , if you can help me I would be very great full, I have a 3 way Drayton motorised valve it seems to work ok but when I have the heating on in the evening and then turn the heating of from the room thermostat the heating will not turn of . I then have to go to the airing cupboard and switch the power of the motorised valve for a few seconds and I then hear a “ rewinding “ noise coming from the valve , do I need a new motorised valve or is it a possible a maintenance issue if I remove the valve and clean and inspect . The lever on the side of the valve seems very loose to the touch . Thank you for your time , Regards, Dermot Kelly .

Brilliant Information, Can i check my issue with you? We have a 2 way valve next to the hot water tank. Think i am correct that when the system is off and it isnt energised that there is the resistance when moving from auto to manual. With the hot water & heating on, the lever is loose? Before we put the heating on, we started to see some radiators coming on and getting warm. Now we have put the heating on as it is getting colder, i am finding that the radiators are getting hot but the hot water is only getting warm. Is this happening because of the valve, or another issue? I will try just putting the valve on the Manual setting for tonight, see if it solves the issue and then look to replace it. Any guidance greatly appreciated..

Hi - don’t mind account (using my daughters) do I need to drain the system if I’m changing the motor and the 2 port piece also? If so, how? I’m ordering full piece with 2 port piece from your store. By the way, I have a Siemens DVA2/5 s same thing? Thanks Eoin

Hi Great Video. I have some queries if you could please answer. I have both heating and hot water. What would happen if it is on auto mode? What setting should it be on if i want heating only or hot water only. Will it close the valve for hot water side if the hot water temperature has been achieved?

Can I isolate the power supply to the head without turning the main power supply off to the whole house please ? Great video.

Thanks for this info. Looks like the motor in mine is burnt out - the lever is loose, so I assume it’s stuck open. I’ve called the engineer.

Hello, my new motor valve opens manually before connecting to the wires but once connected it wont open manually not auto. I thought the old motor valve was the culprit but with new new motor valve it does the same thing. local plumbers cant figure what the issue it. What could be the issue here? Another motor valve open ok manually but not opening on auto. Could this be the wire/electric cord issues?

I have a hot water issue. Central heating works fine. But hot water on its own won't come on (I.e. Boiler won't fire up and pump start), however does seem to heat up the water when the central heating is also on (as the central heating does fire up the boiler and pump) I have two 2-way valves. The one for the central heating has no resistance on the lever, doesn't make the whirring noise as you move it to manually open. I'm guessing central heating is stuck on open. So when only hot water is on the system is getting confirmation that central heating is shut and hot water is open to allow pump and boiler to start. Does this sound correct? And replacing the central heating 2 way valve should fix it? Any advice appreciated

Great video!! Similar problem.I have a sunvic 2701 motorised 3port valve when I turn on the rads on my electric heating panel nothing happens but when I turn on hot water both rads and hot water comes on together working off the thermostat in the hot water cylinder. Is the an valve issue

We have no hot water but the central heating is working. when I try to push the lever, it comes back to it's original position. Is it how it is supposed to be? Can I put this lever to manual to gain access to hot water and then call out an engineer to check the motor etc? What is your recommendation? Thank you for your time to answer our comment.

Great video, my same exact valve is playing up, having to bleeding rads nearly every day, will valve cause this issue ? Any help anyone.

Hi why is it when I leave mine on automatic then only downstairs radiator comes in but when I put it on manual both upstairs and downstairs radiator comes in perfect

Hi...I have a problem with Center 2 Port Motorised Valve 22mm I don't know if is a problem with the head or valve I changed just head ( not valve ) for new one and I found this problem. When I turned on the water for heating the Lever stay in position not moving( motor works ) but my central heating works as well even though it is turned off When I turned on central heating the Lever changes positions to the top ( I think this is like should be ? I have right or not?) The valve wasn't stiff I easy turned by my fingers Pls give me any advice's Thank You

Hi, I have this valve and my heating is constantly on even with the thermostat on 0, I have to turn the boiler off to turn off the heating. When I move the lever there is no spring or any resistance, is it stuffed ? Thanks in advance for help

Hi there! I have a new issue where when any hot water tap is on, it activates the central heating as well. So when I used the hot tap the two rads closed to the boiler get very hot. It wasn't doing that before - my CH had been off for months due to needing new rads. Why is the hot water tap now inexplicably linked to firing up the CH? Thanks for your help!

Can you leave the valve on all the time. Erie AG13A02A Pop Top Actuator 2 position normally closed never does it job on heating. Always stayed closed even when thermostat demand hiked up to highest. House is still cold. Costing me a fortune as contractor keep using the same valve. WHY?! Can I just override as you did. It doesn't say it has manual mode. But has that groove down I can lock it in. Pls advise. Thanks!

Thanks

only one radiator working near tank others are not but hot water is. I suspect it'd this part is it meant to be hot?

We have an issue where putting only the hot water on results in the house still heating up. Would this help resolve that? Thank you

Brilliant video, I tried you method but the valve doesn’t want to move to the manual side, it just moves to the auto side, please help,, many thanks

What is function of white cable and where white cable will go to connect

Hi, I just want to change the synchorous motor, I don't know how to remove the wire from the block though... Could you shed some light please? Thanks so much!
