ICOS HE18 F/L Fault

[kainam]

Hi ive read quite a few on here where it wont start and shows f/l fault, however mine is a bit different.

Shows, F/L fault. Then i switch the boiler off 5 secs and it comes back on fine. It will then work for anything from 5 mins up to 5 days before once again its stopped showing the F/L fault. Weird. and Annoying

Coincidence but about a month ago a plumber came and installed a shower (never ever had a problem before that) but then the problems started next day. He never went near the boiler but of course was messing with wiring...

Just a coincidence? Any idea?? Heelp

When its working, says status "c" and the burner light flashes.

Thanks

Chris

Get it serviced. Sounds like the condensate trap is fairly blocked up.
