It all started about 14mths ago, when the red lock out would intermittently happen. Then this became more frequent but still random, so photocell was changed. All okay for months, but lockout happened on xmas day 
. After turning off the mains and checking the photocell, the boiler did start and run without fault for weeks.
It locked out and would not start last Sunday morning... Checked oil supply, filter, solenoid etc...Fault tracked down to motor getting power but not turning. The back of motor would become warm, but not turn. Could turn the motor/oilpump shaft by hand indicating pump was not/nor part seized.
Checked motor by removing it and connecting directly to a safe 240vac supply.
Original EB90C electric motor made by AEG on this late 80's Trianco TR028/32 replaced EOGB MOTOR 90W M0219012 INTER 10 11 12 99 109 which simply 'plugged' in without any hassle.
Since then, boiler has fired up without a problem.
My question is, under normal running conditions, how hot should the back of the motor become? It's to hot to touch for more than a few seconds, but no burning smells or indications of overheating.
