DIYer here and this has been annoying me now for a few days.
It all started with the boiler (Potterton Suprima with a new board) in the kitchen just clicking on and off failing to light. A few minutes with the meter and I speculated that there was a pump motor problem especially since spinning the pump by hand sometimes got the system running. So off I go and buy a new pump.
The system magically kept running though so I left it alone for the day until I noticed that I had hot water but no heat, when there was a call for heat there was no activity from the boiler. My initial thought was that I'd disconnected something with the meter but now I was making myself problems. Time to call the "Professional" heating guys
"Professional" comes out and looks at the system, I mean just looked and says your pump is bad you have another one so just replace it and it'll fix everything, ask are you sure everything, I have two sets of symptoms? He says yeah and promptly leaves, 10 minute visit. I'm complaining about that to the company.
So I change the pump, no joy, and then notice that the mid flow valve isn't changing position for hot water. I move it by hand, low and behold the heat system now exhibits the same problem as the hot water. My "professional" didn't bother to check that one?
Pull the system apart and find that despite voltage the motor won't move even on its own so another quick trip out and get a new motor, fit it, no joy.
Now I notice that the new motor says it is 230v and the terminals feeding it only read about 90v which is odd but might explain the motor not working.
At the moment I feel like I'm throwing good money after bad because I can't seem to track down what this intermittent issue is, some days the boiler starts, others like today nothing. My gut is saying boiler control board but that is an expensive "trial"
Does anyone have any tips to help me trouble shoot this?
Things I've done so far are cleaned the igniter area on the boiler
Any help would be great.
Thanks,
Gary

Change the pump
Change the actuator on the valve
Reset everything repeatedly
Checked the wiring as best I can with a meter
Changed the thermostat on the boiler since the old one just spun around
