baxi combi 80e hot water problem

olliebears · 20 Dec 2008

Hi all

my baxi works great! but only on central heating I get no hot water at the tap The water only setting went first but I got hot water through the CH & water setting on the selector switch ....now I get great hot water through the rads but always cold out of the taps........thought it may be electrical as in the PCB or switch but now not so sure. any advice?

Thanx in advance

Diaphragm has gone

Thank you for the fast response

Does this mean I have to drain everything or can this be done by shutting off cold water inlet and and draining off at boiler drain point? Book I have just says drain primary circuit....does not say any more than that before I take apart the pressure differential valve and change the diaphragm.

usually you only need to shut off the cold mains to the boiler and open a hot tap to release pressure.

Drain the cold water out into a bowl etc.

Cheers Dave .......I am assuming here that this diaphagm failure will also stop the Water LED from lighting up when the switch is turned to hot water only

If the diaphragm has perished then nothing at all will happen when a hot tap is turned on, as the boiler won't 'see' the HW demand.
