called to this horrible boiler today, i like to condemn these normally but for various reasons cant do this one.
system filled and vented to 1.5 bar. all electrics perfect. pressure switch working.
basically turn the unit on, and after 20 seconds ish, the fan turns on and off cycling every second (ish) - nothing else happens
i removed the +ve pressure hose from flue to switch and the fan runs constantly without anything else happening.
the flue is not blocked in any way, even though termination is ncs
i know its the pcb but looking forward to hearing from anybody who has seen this problem before!
ta.
anybody??
