baxi boiler 105e

[tenerife]

Hi

Can anyone help me because couple of gas fitters that I have had in can't.

My baxi 105ecombi boiler heating switches on ok and runs ok until I turn on the hot water. When I turn off the hot water the heating does not come on. The outlet outside is dripping.

A couple of gas fitters have been in and have tried several things the last thing changed was the mitre switch - the heating worked ok for a couple of weeks and then bang the other day its back to when the water turns on the heating does not come back on and I have to switch the boiler off and turn it back on again.

Can anyone help me

thanks

The outlet outside is dripping.

Why didn't the gas fitters repair this?

cos they were plumbs

when the water turns on the heating does not come back on and I have to switch the boiler off

What lights are displayed when this happens?

 

[tenerife]

I think the light for the heating and the water stay on and it thinks the heating is back on -

If that is the case (I don't think it is) your PCB is shot.

Probably a sticking DHW plunger.

Hi
Realised what a PCB was after a I sent message.

As for DHW - a new diaphram was input but the same thing still happened.

any ideas!!
