Thanks to some great advice on this forum I have changed the following parts :
Suprima PCB (ebay job)
OH Stat
Thermistor
Motorised 3-port Valve
BUT.... I am still getting the 'lock-out' problem after the boiler has been in use for abour 30 mins or so. It is strange, it works perfectly when cold but it seems to lock-out once it has been running for about 30 mins. I have tried adjusting boiler temp control and thermostat but alas nothing. Does anyone have any ideas what is going on?
Forgot to add - Once the boiler is warm and it locks-out it wont reset and simply locks-out again immeditately unless I leave it for 10 mins or so......
Cheers!
