Hi thisworked last time my batteries run out but this time am getting code co7 instead of co5 any ideas what I do as have to keep switching everything off because heating stays on red hot doesn't switch off???????
Thanks for this video. I have had problems with my heating working intermittently for the last few months. It will work fine for a few days or maybe a week and then the boiler won’t fire when the call for heat is made. If I turn it all off for a couple of days and then start again it will work again for a while. I assumed it was the boiler at fault nd maybe the PCB but then I noticed the hot water on its own works fine, boiler fires no problem and it works as it should. It only seems to be when CH only is selected. I can hear the boiler clicking on and off trying to start so I think it communicates with the room stat, goes to start and then the mid position actuator doesn’t move as it should. Does this sound the likely issue to you because if it was the brass valve then the hot water wouldn’t work either? Thanks.
Demand for hot water tends to be from the stat on the tank - rather than the 3 port. When heating demand on you should be able to hear the microswitch be clicked… Or, if you take the cover off the head you may be able to actually see the lever hit the switch. Be careful - 240v knocking about. I really will try and knock a video up later today and upload it - been meaning to do one for ages….
The hot water works fine yes When the heating is selected on the controller I can hear the boiler clicking as if to try and start. I can hear the click in the airing cupboard as well from the actuator, it might go anything from 0 seconds to hearing the pump start for various lengths of time but the boiler won’t fire (but only for CH), sometimes it will work ok and start straight away. The boiler seems to be communicating with everything ok but I just wonder if something inside the actuator is not working every time as it should hence the intermittent business
That's a great video! Thank you very much! I have just moved in to a house with quite old Worcester 24cdi rsf that has got mechanical clock/timer and it's broken... so was wondering if I could have a thermostat instead as there is only 3 wires coming out the boiler PCB into that clock/timer unit that sits in the bottom panel on the boiler...
Spend half hour trying to repressure with the values on the pipes and got nowhere - totally the wrong valves to be messing with. Then I found this video - I couldn't see the "twiddly knobs" on my unit so didn't think to try them, this video set me right and I was back to piping hot water in minutes - THANK YOU
This video was so useful, thankyou! Recently my thermostat is showing a much higher temperature than what the actual temperature is in my home, it is not positioned near a window or a heating source, would very much appreciate any advice!🙏🏼
Should it completely seal one side of the system when it's switched to heating or water only? Mine just restricts it. Can still blow through it if I try
Thank you so much …really informative…the little black lever is broken..does it have a name so I can get a new one please? Hve a great week, you’ve been so calmly helpful!! 😊
Well - if i were you i’d probably just take the lever to screwfix/a plumbers merchants like wolseley/plumber centre and explain… they’ll probably just sell you an isolator with a lever on for a couple of quid. Just swap the lever over and ditch the metal bit. Hope that helps. Have a good one
Hi. My EPH controller buttons are working. The screen is up and showing room temperature and date as normal but none of the buttons are working. Could you please advise on how to sort this. Thanks a lot
I dunno if you'll see this but a quick question. I get this error every few months, no biggie, but for mine I turn both valves towards me till the pressure goes up, then both away from me to close them. Is.. have I been turning the left one the wrong way and do I currently have it wrong or COULD my boiler be different? It's a baxi platinum combi boiler with the exact same valves you show here. I only ask because doing it the way I do it has worked fine but on the right valve there's little drips of water starting to show up and I'm wondering if maybe I'm the cause from not doing it correctly. Thanks!
Hi how does the copy work plse is it possible you can do a quick demo video on this please I'm not tech savey & the booklet not to clear or if anyone out there can help me Thanks
