trianco 50/65 boiler locking out.

[CottageKen]

Hi anyone, I have a Trianco 50/65 boiler fitter with the minor 1 burner
and satronic control box.
It has just started to lock out regularly.
On starting, it will get hot, then lock out. If I press the reset it will burn again
for a couple of minutes then lock out again.
I have removed & cleaned the photcell and this has made no difference.

Has anybody any helpful suggestions.

a common fault is the danfoss oil pump soleniod coil breaking down when hot. available seperatly and easily replaced
