I have reset the Potterton controller EP2002 but boiler not firing

ac, June 2008

power in---programmer---motorised valve---boiler ignition.

thats a basic description of live supply. if your programmer works then problem after that. you need to know where power gets to to determine fault.

90% motorised valve fault. programmer sending live supply but valve not making end switch to send live to boiler.
