Hi
I have a Vaillant Turbomax 828E showing F.28 fault, Has worked fine since I fitted it in 2002. Its developed an intermittant problem in the last few weeks, doesn't always fire up (no heating or hot water); works ok in the morning but heating doesn't come on in evening , when we also lose hot water,comes back on if you switch it off for a while ( no set time). cleaned electrodes, hoovered fan and burner sections, was ok for a couple of days. but the heating didn't even come on this morning and its Freezing today, (hence the name MrFreeze), cleaned electrodes again today and it started working again after a while but I know this isn't a permanent fix,Have ordered new set of electrodes but on reading up on this the (F 28= No gas, Incorrect gas valve adjustment, Electrode defective, Ignition lead defect, Electronic lighter defect) is a common fault with the 828E and no particular fix, Just wondering if you guys know any more on this before I end up ordering more parts, any help on this will be appreciated,
