My 105HE stopped working on both DHW & CH.
Anyhow, after info gained from this site, I removed the front half of the divertor valve and found it to be seized. I cleaned it up and renewed the diaphragm and now the HW is working brilliant.
When I place a call for CH, the pump starts up but the boiler doesn't fire up.
I am at a loss to what could be the problem. I have tried to follow the fault finding in the installation book to no avail as each level is pointing at one of the LED's lighting up to indicate a fault.
None of the fault LED's are lighting up when a call for CH is made. The push-rod on the differential valve connects with the micro-switch and the pump starts running but it doesn't fire up.
I've also renewed the CH diaphragm and still now joy.
Any information will be greatly appreciated.
