The microswitch turns on the pump when operated by me. We then get hot radiators. The pump does not seem to come on otherwise. Seem to have another problem as well as even with the heating turned off and turned down to zero on dial on front of boiler the lockout has tripped over night.

so which caused which as it seems strange that both these things go wrong at the same time. Cheers Paul

Has expansion vessel problem been caused by the pressure going towards 3 bar? Which would mean this is a side effect of another problem or is this likely to be the problem in the 1st place. ie if I sort expanssion vessel problem is the boiler likely to work as I have to make a decision on cost...

I have taken the black top off the valve on the big red expansion vessel when I pressed down the centre of the valve water dribbled out. I assume this is bad news?

Is the micro switch in the diverter the only thing that controls the pump? because if so there is no way this will work as nothing gets anywhere near it when the actuator moves. re

I have taken the diverter valve off the boiler leaving a keyed vertical spindle on the valve which moves manually about 20 degrees. Turning the heating on with the solenoid off the spindle, the solenoid continually turns but springs back when it gets to its fullest point. There is also a micro...

Thats what I don't understand as every other listing on here says that when lockout button lights up is to do with lack of oil. I just wondered if their is a pressure sensor or valve that would trip the lockout to stop burner as the pressure goes up to 3 bar. This would stop the boiler pressure...

Hi hope you can help We have oil We did not run out of oil Hot water works well Heating runs warmish not hot Honeywell V4044f11411 diverter valve, pump side and pipe that runs to tank run hot. Pipe to radiators warmish. Pressure guage goes up. Manual slider on diverter valve loses spring...
