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.
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
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 👍
paul rossiter Thanks mate.. it’s funny out of all the vids I produce that’s the video that I filmed a dozen times until it was right 🙏🙏🙏 pleased u enjoyed 👍
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
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.
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
I don’t understand though. When on CH why does it pass through the diverter valve on the return. I’d of thought the flow would go to the diverter valve first and then go to the plate or radiators.
@@drpipe so the pressure relief valve (blow off) and expansion valve are all connected to the pump housing (the heating return?) thanks great vid btw mate
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?
Jonathan smith yes def could 👍 I’m trying to work on a way to flush Hex that would be the only way I Could guarantee 4 sure. Did think of running on LPG to try. Maybe future one as I have kept the Hex and marked for sure. Thanks for the comment and watching. 👍
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
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
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.
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?
@@drpipe Actually it was ok to having low temp to both HW and CH. But Vaillant blocked this for Dutch boiler version. Maybe because the boiled would not condesate with the valve in the middle position. No idea. I would want to test it.
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
Dr Pipe gotta video on it or is this it and I’m just slow 😂 I understand the dhw and the Ch water doesn’t touch each other inside the plate I just don’t get why there is a diverter from the ch side that then feeds dhw too.. hope I make sense 🙋♂️
@@drpipe hi I have the eco tech 28 and its blowing the circuit board fuse, the engineer changed the pump but it blows the fuse he now thinks it could be the fan, have you come across this before.
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!!
Great, as you have so much to SAY on the subject put your money wear your mouth is and….buy me a mic at www.drpipe.co.uk leave a donation or buy a product .. ok ?
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.
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.
One of the best teaching videos, Big thanks

Can you do this for a worcester
Appreciate your perseverance and sharing your knowledge 👍
@@RobertJones278 pleased you enjoyed 👍🙏🙏
Very useful. I just replaced a leaking diverter on mine and I'm not considering giving the whole thing a good clean out.
You did a good job here bud very well explained !
Nicely explained

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.
Brilliant video and explanation more like this please your an inspiration to the industry
Thank you
Great informative video
That was really good. I had no idea the CH took a route through the small heat exchanger.
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
Anthony I’m just filming next weeks ! Enjoy your fish n chips 👍 will do the kit one soon.. have been asked a couple of times now. Thanks for watching.

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?
It could stay in that position and give low temp to both Hw and Ch.
@@drpipe Actually it was ok to having low temp to both HW and CH. But Vaillant blocked this for Dutch boiler version. Maybe because the boiled would not condesate with the valve in the middle position. No idea. I would want to test it.
What does the screw do on the diverter valve? The adjustable scew you can see
Bypass adjuster
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.
That’s why I made it ! If you can understand and “see “ how it works then it will make it super easy to repair. Thanks for watching
Thank you plz upload more similar video's if you have time.
Was great , thanks
Great video , could you explain a little about the bypass valve on the div valve please :)
When flow is restricted it allows the ch circuit to bypass for safety reasons 👍👍
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

Michael H Ch water goes around the rads.. but when demand for Hw is present diverter (hence name) sends thru the Dhw plate to create Hw 👍

Great content, do you know if Vaillant offer an upgrade from the old to new style hydraulics you mention at ~2.30?
Yes it’s a chunk of 💰 for 2 pipes and change of position of Wps.. called f75 kit
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?
Not at the mo 👍
Think I’ve got it sorted. Rigged up supply dc from battery and tested signal wires.
Great vids!

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
Brilliant ain’t it... it’s like a pension 🙏
