Worcester ri 24 service mode max wouldn't fire but blue flashing light 5 times

That negative fan test is bullshit, ive had it pass that test but need a full strip and clean, and fail that test but not need a strip and clean.

Could just be me but i dont do that test, i remember when it came in and i find it proves nothing

Strip down every 4 years or new customer

Yes, totally agree. I tell customers a proper service every 3 years.

Every third service is a full strip on the ones I have on a service contract. Cheers kop
