So I managed to get a new oil pump and a gauge so I could set it up. Fir the last 2 days heating has been working fine. Heating engineer coming next week to set everything up. So looks like it was a pump/solenoid issue that I had.
Haven't had a chance to look at burner yet but might pick up new solenoid any way and try that. I would go for a new pump but I have no way of setting up pump pressure and my heating engineer can't make it till end of next week.
I've had the oil pump off and all felt free. Checked drive as I know that's a common issue but that is fine. I feel that it's a fuel issue as it did fire up and run for a bit then surly the only reason it would lock out when running is due to no fuel.
So reset and tried to fire up boiler. Boiler went through start up sequence and fired up fine. It then ran for 2mins 40sec before locking out. Took photocell out and cleaned in up (wasn't dirty). Put back together now won't fire up. Oh the joys. Think ill leave it tonight and start a fresh with...
Ok when I was checking the voltage output I stupidly had the photocell out there for it was giving the false flame signal hence no voltage to solenoid. I then tried it with the photocell covered and I got voltage. So I put everything back together and she fired up and ran fine for over 1 hour...
Photocell resistance when covered =9kohms when exposed to daylight = 200kohms. So looks like photocell is fine. My understanding of the photocell was that when it did not detect flame it allows the electrodes to spake then once it sees flame it stops the ignitors. I did not realise it was...
OK will check the photocell. It was replaced 2 years ago as I gave the burner a major overhaul due to. Intermittent issues. I replaced photocell, ignitors and control box. I replace the Nozzles yearly as part of its service.
Yes John it's a danfoss BFP11R3 pump. Just away to get my voltmeter out and test. Any idea what reading I should be getting on the solenoid resistance and what pins should I be getting a voltage across from the control box.
So my boiler has stopped working. I've traced the fault to no fuel coming out of the pump outlet. So I thought OK pump is faulty. So checked the pump drive all good there. I then cracked open the bleed valve and turned boiler on and fuel came out. So that's got me thinking is it the pump, the...
So I was round tonight to look at my mates. Hive. I rewired the receiver to how it was previously then linked the signal wires from. The old wall mounted thermostat and everything is now working as it should with hive.
Yeah my plan when I go round is to rewire the thermostat wiring at the receiver end then link the signal wires at the end that would have connected to the wall thermostat so that it would constantly be calling for heat. As see if that works.
I belive its a y plan with a 3 way motorised valve. I've not had a chance to check his system. Just wondering if it was something simple that might have been missed.
