My Combi is still refusing to work. The engineer has replaced the flue fan, expansion vessel & PCB but with no joy. When turned on, all the warning lights and temp lights come on except the yellow 50 light. Pressing the reset button results in a loud solinoid click inside the boiler, then after a couple of seconds all the lights come back on. Does anyone have any suggestions?
Thanks

has the engineer put the right epron key in the pcb?

is the boiler now ok? what was the original fault before changing all these parts? and if you have the PCB can you send it to me to check it?

you have changed a lot of parts to your boiler does the original problem still exist or has a new problem manifested after changing parts?
faulty pcb or check it again.
Check also does pump work on demand.
