Heatslave 12/14 Lockout

[tsenn]

Hi All,
Our old reliable combi oil boiler of 15 year or so years has just started to go into lockout. I have reset the lockout a number of times and the boiler does restart and continues on for some time, but will eventually go back into lockout.
I have found that if I turn off the central heating side of the boiler, then it will continue on (multiple continuous showers) with out problems. If I turn the central heating backon then it will eventually go into lockout!
I have checked:
Oil levels OK
Photocell cleaned
replugged all connectors (with power off)

Any ideas, before calling in a professional?
BTW - the boiler does appear to be hotter than normal, but that could be just me.

Cheers for any suggestions.
Tim.

Solenoid Coil!

Thanks 'Terrywookfit' - I have found and ordered one from the net - it looks fairly straight forward to fit (I hope). I will let you know the results.

Cheers Tim.

Solenoid coil arrived today and it took about 5 minutes to fit, all I needed was a hex key. The system has been running for about six hours now without problems.

Thanks for your suggestion and help Terry you have saved me a callout charge

Cheers Tim.
