Ariston euro combi a/23 mffi pump running nothing else .

[clive]

Hi all,

I'm new on here so please go easy on me , got called out to a aristo a/23 mffi , pump running but nothing else.

seems to be power to air pressure switch stats ect, the right hand pcb , got power going to the pump,

none going to the fan only 12volts going up the neutral wire to the fan. The red light on the right hand pcb does not
illuminate but boiler is on as pump running. Checked quick blow fuses all ok.

i think it might be the pcb. Horrible boilers I know.

help or advice would be much appreciated. I am gas safe registered 562134
