Title: Baxi 105e hot water problem..
Post by treesypeesy on Dec 14^th, 2013, 11:24am

Hi guys, now listen, please don't judge me I am a single parent with little dollar who is just trying to do her best!!!
Ok so my problem is I just moved into a new house with a baxi combi boiler 105e, I mean its so long since I lived in a house with central heating I couldn't even figure out how to turn the heating on and fire the thing up..SO.... as everything else had been turned off ie stop cock etc, I looked at taps underneath and turned all of them on.. and then tried hot water and was met with this god awful shaking and rattling, yes in hindsight I had turned the supply on that increases the bar pressure, duh, first problem...
Anyways the boiler fires up ok for the heating, but the hot water is not kicking in with or without the heating on.. no light where the tap is.. so via google etc I figure its probably the diaphragm and buy and replace that easily (the diaphragm was damaged).. when I turn taps on now the tap light comes on the boiler fires up but still no hot water.. and the flames die after 20 seconds or so and then come back on etc... meanwhile the temperature lights are going up and up.. So next I figure it could be the thermistor and replace that easily enough..
NOW I am left with boiler firing up, occasionally flames die, but still no hot water, mostly none, sometimes a little, sometimes tepid..
My question is what is the most likely thing I damaged when overpressurizing it, is there anything else I can do/try, or do I have to eat into Christmas budget and call someone out??
If you made it this far and haven't fallen asleep I would really appreciate any advice x

Hi,

Worth mentioning if it's a rented accommodation it's the landlords problem.

Do you know a good RGI friend/family that can check the boiler for you, whats your location we may know a good guy that covers your area

Hi,

Sorry don't know anyone in the St Austell PC.

It could be anything including a blocked Plate HX so need to do a few checks to avoid part changing unfortunately.

It may be worth asking Baxi how much for a fixed price repair.
