HOt water problem with Baxi Combi

bannistuta · 2 Jul 2010

Hi All

Recently had a problem with hot water on my baxi combi boiler. when turning the hot water tap on, i get no hot water I have to turn the water dial off and on to fire the boiler up. When it does fire up the green water light flashes and the temperature lights start to increase but water occasionnally gets hot but mostly stays cold or luke warm.

Any ideas what is causing the problem? Thanks in advance

Sorry

I'm pretty sure its a baxi 105HE.

ok.......does the pin on the front diferential come out and make contact with the micro switch when you open a tap?......front bottom left.

If it doesnt your diaphram has split and needs replacing.

Does your flow pipe for heating warm up when you call for water? If so it is the diverter valve that neds replacing.

It maybe other things to but check these first and report back

Sorry it's actually a baxi 105e (if this makes any difference) I can't locate the microswitch, don't really know what i'm looking for, as for the pipe warming up, the pipe on the far left gets hot if this helps?

Thanks

if pipe on far left gets hot when your running a tap, sounds like the divertor valve is stuck causing the heat to go to your rads instead of to the plate heat exchanger to heat your water.

is there anyway of getting it "un-stuck" bearing in mind i don't really know what i'm doing!!

what would it cost to get someone to do it?

Thanks
