Vaillant Ecotec Hydro Assembly Explained. Dr pipe 

One of the best teaching videos, Big thanks

Let me know what you think of this as I have been working on this for a while to help you guys understand this boiler. I filmed this 4 times without success.. but never give up on what I thought would be beneficial. Thanks for watching.

You did a good job here bud very well explained !

Excellent clear explanation. I showed this to a very experienced plumber and we were able to solve an F 75 fault by replacing the dirty pressure sensor in its new concealed location as shown in your video. Thank you

thanks .great video .just took apart an old vaillant and watching your video .very helpful .really appreciate it.

This guy is the master. What an amazing video. it was explained so clearly Thank you

The amount I've learnt in 2 days of watching your videos is astounding

excellent video and you explained it really well thank you very much .

Dr Pipe....gotta say that was a quality strip down and very educational for us. You strip it down like a corporal and his and his L85 rifle 👏👏👏👏👏👏 Very knowledgeable. Cheers 👍

Great Video, couldn't be explained sny better. I wish they were as easy as that to dismantle and whip back together in sn awkward cupboard.

Great demo of this main assembly. I'm not a heating guy but wanted to try and figure out why all of a sudden I have zero hot water at the taps with this boiler.

Nicely explained Excellent! Thanks

Great video, thank you for taking your time in this 👍🏼

What a legend you are!! Just out my time and this is a big help!

Thank you for all your time, effort and commitment.

Great informative video

That was really good. I had no idea the CH took a route through the small heat exchanger.

Excellent video mate and you explained it really well. Appreciate you taking the time.

Love these video breakdowns, great for the likes of me as a trainee.. please keep them coming, perhaps a generic breakdown of common boiler faults, and full strip down explanations of boilers pleassssssse

Thank you alot! Very learning

Thanks for video .it is so helpful .

Absolutely brilliant video, so well explained. Thanks

Hi your vids are really good and I've been in the trade for 45 years.

Great video once again must have taken you quite a while to video thanks for this as is a great learning kerb on how this boiler works 👍

Great help, appreciate the effort gone into making the video's.

Enjoyed this content. Wish you'd said yeah a few more times x

I am just in my local takeaway getting my dinner and I am going to go home and watch this on my tv and put the feet up .should be good. Do a video of you boiler repair tool kit .you seem to have nice tools

thanks very good explain .

Brilliant video and explanation more like this please your an inspiration to the industry

Thank you so much for this detailed video!!

Excellent video Thanks

great keep up the good work, much appreciated

Yes i did like it. Great info many greetings from Holland

Was great , thanks

Thank you. That was really great. The problem I have with my eco pro is that water is dripping from both nobs. Though I appreciate and understand your decomposition of the system, I do not recognise the tools you used. Help

Thank you very much.

very useful.....thank you so much

Very good video! Greetings from Hungary!

Amazing thankyou

Great job 👏

AND THE BEST EDUCATIONAL VIDEO GOES TO !!!!!!!!!!!!!!!!!!!!!!! Dr Pipe .

Nice video😉😉😉

great video.So well explained.👍👍🙏

Still good I've watched it a couple of times now, I came back to this after an infamous f75 fault to try and figure it out.

Would of been good to see if you could of got it running again :D great video though keep them coming

😊👍

Thank you Sir. Please do more videos like this, it helps alot, specially new engineers like me. Thank you so much.

THANKS boss

What issues would you get if the flow sensor isn’t working properly on a turbo max 282?

Great video , could you explain a little about the bypass valve on the div valve please :)

Brilliant

Good video

I have no water coming out of my hot water tap should do you think flow blockedge

Tanx for the upload,never seen hydro assembly video on you tube would you do a video on tools you use on different makes of boilers plz.

Great content, do you know if Vaillant offer an upgrade from the old to new style hydraulics you mention at ~2.30?

👍🏼👍🏼

Hi I have a valliant ecotec pro 24 and I'm having no hot water and f75 code what's the most likely problem the water preasure sensor ? The boiler was installed 2016 thanks in advance if you can shed some light .great video by the way well explained

I was hoping you could help me with a diagnosis on an Ecotec Plus 837. Working fine for several years and then a week or so ago several radiators stopped heating, the only one working really well is in the same room and a couple of warmish ones nearby. Hot water working perfectly. I hoped it was a simple pump swap, it wasn't! The system is really clean, I've checked the diverter valve and the rubber hoses have no blockage. I've noticed that the flow and return temperature (D40&D41) are quickly identical after the boiler fires up, so the boiler cycles down and just pumps, the boiler is internally bypassing which I validated from the temperature of the flow and return pipes. The bit I'm not clear on is whether I simply need to replace the internal bypass valve - can that be broken or is something else creating this problem?

Excellent video. Very informative. Keep it up. Whereabouts do you work?

sir I have a question, this aqua signal ignites the gas boiler but is it a continous signal or just a one time ? the reason i am asking this is , i am doing a project and i have connected a electric heater to heat water but i dont want to run both heaters at same time and want to save my gas money so i figured if i just block this aqua signal , i can stop gas boiler from igniting ! so please if you reply it will be a huge help ! thanks in advance!!

What does the screw do on the diverter valve? The adjustable scew you can see

can you explain the screw for the bypass on the DV please.

Hi very interesting. This boiler has an option to put the diverse valve in the middle position (D.070 = 1 ). What are the disvanteges of this, besides lower power? For some reasons they blocked the middle position for the Netherlands. Maybe any suggestions why?

Hey dr Phil I have error code f75 on my vaillant boiler I top up the pressure will be ok for a few days then turn the heating up the f75 code come back top up the pressure work fine for few days then story repeated what would you recon could it be I have no leak on the system many thanks.

Thanks

I have just stripped one of these units. Do you have a tip for testing the Pressure sensor and the Flow sensor with no power to the unit?

Very nice and clear explanation but one explanation is missing : the use of the shunt between the return of cold water ( little hole of the diverter valve ) directly to the exit of the warm water ( second hole from bottom left ) what the use? regards.

Hey Dr. pipe: The video is good, but the audio quality is poor, please use mic near mouth for clear voice in video.

May be because I’m sleep deprived or a stupid question but why does the central heating side have a diverter that feeds the Dhw side aswell wouldn’t that be contaminated with the central heating water.. new in the game and trying to get my head completely round all components in our wonderful world of work.. cheers bud

Apprentice here. I’m just confused on why they’ve done this set up to traditional type set ups

lol still got issues with the WPS even though they moved because of issues, F75 fault anyone?

Is doesn’t matter where they move that lwps it’s still a fault . That and the diverter

Übersetzen in Deutsch bitte.Danke.👍🙋

It a Combi

Not a cheap boiler. Sadly uses poor plastic materials and bad design. This renders it prone to failure and expansive repairs. The bi-matelic scale indicates lack of scale inhibitor. No excuse for a leak at rear of the plate heat exchanger. The video is well presented.
