Hi Jamie, thanks for this very helpful video. Just one question my problem is a bit different from yours, the problem is my hot water doesn't work but heating does by doing some research it is Diaphragm switch and I got bit leak like yours and when I pull microswitch lever myself hot water comes on sell I just change the potterton performa pressure differential valve. Please Help thank you
This is such a helpful video - thanks so much. I'm about to so the same, just one question did you turn off the cold water inlet (tap on 4th pipe) or did you just switch off the water completely ? Or both!!?
I've got the same boiler and it seems to be leeking in between the diafram housing and diverter valve , is there a rubber seal or something in between them that could be perished thanks
Hi Peter, im afraid i dont know and it was a long time ago i made the video. Like ive said in all my replys im not a boiler engineer. Hope you find the answer! J
Hi Jamie , I meant the 4th pipe leading into the boiler, which is the water inlet. I meant did you turn that tap off , but obviously you meant the domestic stopcock. Apologies if I wasn't clear. Thanks for your reply - like I said this video is very helpful and is going to save me and I'm sure a few others a bunch of cash.
Problem is the rubber oring on the spindle of the diaphragm. U don't need to take the diaphragm out the brass end unscrews to reveal the spindle and oring. Your welcome in advance. Lol
there is absolutely no need to drain the system for this repair. Just turn cold water supply off to the boiler (second iso valve from the left) and open hot water tap. That is all!. Also when fixing boiler you never drain the system. You isolate the boiler at iso valves (first left and first right) and drain the boiler only through a boiler draining point located next to the pump on this particular boiler!
Its looks like you have a faulty micro switch as you have described but there may be the following things to look at the boiler before coming to conclusion Thermistor, Micro Switch and Diverter Valve it is very difficult to tell when you are not in physically at the boiler Check these components but its more likely Micro switch or DHW Diaphragm
Turn the cold water off, open the hot water tap put a small tray for the remaining water in the system then you Do NOT need to remove all off for this parts for this problem. U Just remove the micro switch and change the "Deverter Valve / Gland Nut" in eBay around £3.5. should solve the dripping problem.
Yes yes and that's how you change the Diaphragm inside the divert-er valve of a Baxi 105e boiler. Clean the unit and replace with new diaphragm and the pins if its need to change. You isolate the boiler and drain the primary circuit before carrying out this maintenance. Its is best to change both diaphragm DHW and CH so later you don't need to come back and do the CH. Gas Safe Register is not required with this maintenance Video should be more educational a step by step guide any way well done
Hi, Jamie, Do you think one can just take off the microswitch and then just unscrew the 6 screws to change the diaphragm? Did you have to take the whole unit out and then disassemble to change the diaphragm?
Hi I think it may be possible to do it that way and it sounds much easier! Im no boiler expert so was more or less just experimenting when doing this. 11 months later and the boiler is still working fine.
Jamie Crawford Jamie thank you for your help. My water heater is working fine again. Same problem. A hole in the diaphragm. One more question. How do you maintain your water heater? Do you flush it? I don't think it says so in the owner manual. It just talks about cleaning each part, etc... If anyone knows how to maintain, let me know. One plummer came out and "maintained" it but only checked outside tubing, and checked for leaking. Did not flush or anything like that. I am not sure if I can really trust any of them...
James Shin Sorry James Ive just noticed this comment now! LIke I said im no expert in this type of thing and just fixed the problem that I had, so cant help you with this problem. Jamie
Oh, no prob. I already fixed my own boiler long time ago thanks to you and others in the internet. I had a hole in the diaphragm. I hope others can also save money like I did. Only spent about 30 bucks when the plummer was asking for $3,500 to replace the whole unit.
James Shin Good for you. it's amazing how much you can save on repair bills. I've fixed my own boiler on more than a couple of occasions. Thank goodness for RU-vid and Internet forums for that extra help and advice. Some are reluctant to give advice but they're the ones that do it for a living and rip people off at the same time. I know so much about my own condenser boiler now that I would be happy to replace it with the same type and brand should I ever need to because the inside is so familiar to me.
Hi Chirag, Im afraid I cant help you with this problem as im not a boiler engineer. I only changed the diaphragm myself as it was an easy job. Sorry I cant be of any more help, but the comments from Taqqiyastar may be of use to you.
Would be good if you filmed the whole thing and just left the camera running rather than all the cuts. Also, you didn't turn the water off. This video could have been so much better.
ok the silver metal bit is now rusty on mine, had a shower this morning, hour later and that part on my boiler was dripping real bad i was told by a boiler guy that its a rubber washer broken and he gave me a replacement, seems to be a common problem for baxis, cant see one in this video lol
No you don't need to drain the system just turn off to cold supply to the boiler and open your hot tap. This part of the boiler is not part of the heating system so that can stay fully pressurised. Although don't touch it if your not has safe registered leave to people who know what they are doing like me
I never touched any of the gas parts in the boiler, this was water only. The leak stopped and the boiler is working fine. With a name like happy slapper its easy to see that you are a troll - you tool!
Alan metclaff Depends what country. In the UK, as far as I'm aware you cannot connect up the gas - that's illegal. But you can do the rest, so like 99% of the job - all the water and electrical parts. I personally think it's a crap law that doesn't allow people to fix their own boiler.
if you break into the gas parts of the boiler or anything connected with flue and disposal of combustion products then you need to be gas safe registered. There's very good reason for this. you can repair anything else like electrics, hydraulics etc
+RA30st08 The reason you can't legally repair gas parts on your boiler paid or not is that usually when it explodes it's not just YOU that's in danger. It's a duty of care to get trained and prove competence. common sense really
Simon Shields I understand the rationale dude. As non-tradesman that has done basically every trade in my spare time, its hardly rocket science. Use the right parts and decent tools mixed in with a shred of common sense - equals a job done on par with the best 'qualified' boiler installer. The same goes for mechanics, I've had to fix repairs done shoddily on friends and family members cars because they've given it to the unexperienced yet newly qualified mechanic. I could for instance, work on the brake system of a 16 seater transit van, that could end up killing them all plus how many extra in a pile up due to incompetence....so why is that not illegal!? "It's a duty of care to get trained and prove competence." AKA - pay some business to give you a shit course and simple test that lets you do something you've already known how to do but now you've a shiny certificate....bravo. We both know that the majority of gas explosions are caused with wankers tampering with meters. Not competent people with common sense installing boilers. And by the by, there's PLENTY of 'certificated' installers that still manage to fuck it up and cause loss of life. A company near me fitted a boiler and killed 3 with carbon monoxide poisoning just last year.
You shouldn't be tampering with gas appliances mate. It's against the law and you cannot even remove a boiler cover without being gas safe registered. Just giving you a heads up.
Ok thanks for the comment, I did not know this. The comment below (Alan Metclaff) seems to disagree, but like I said I have no idea about the laws around boiler maintenance etc.
@crissyno1. Rubbish!!! It's not against the law for a homeowner to mend his/her own boiler if they have the confidence to do it. Please find and quote what law! A heating engineer only has to be Gas Safe Registered if they are going to perform work on other peoples boilers for payment of money., i.e.,..they do it for a living. Even then, Gas safe Registered means naff all. It just means they are 'Competent' (supposed to be), in what they do. I have saved lots of money on my own boiler repairs. I replaced a PCB, replaced a couple of heat sensors and replaced an Air Pressure Switch, (APS). It's not rocket science. It's either a mechanical fault, electrical fault, or a plumbing fault. Gas itself rarely comes into the equation unless you start messing with the combustion chamber. No engineers can ever rip me off again!
Jamie Crawford Take no notice Jamie. he's talking nonsense. You have every right to fix your own boiler. I do it all the time. Just the other day my heating wouldn't work. Flame failure lockout as soon as it tried to fire up. Consulted manual and noted I just needed to replace a temperature sensor. (Manual said - contact an Engineer). Sod that! This is something I can do myself I thought. So I ordered one for under a tenner, old sensor out, new one in,..five minutes job done! A simple plumbing job. Not gas. Engineer probably would have charged me not much short of a 100 quid!
