Question about Computers & Internet
I have a new valliant pro boiler showing a faulkt code of f28. It ignites then switches off after about 5 minutes. I have checked the rads but on one there was a leak coming from the thermostat. Its lost lots of water. The carpet is saturated and it was dripping into the living room. The rad is in the bedroom....

Got exactly the same problem with mine. Manual says f28 = fault in gas supply, gas pressure too low. Boiler will ignite but goes out within minutes? HELP!

IF the weather is extremely cold, and you're getting F28, the external pipework may be blocked with ice. Warm up the external pipes (lag them if you can) - and now see if your boiler will re-ignite.
A friend fixed our condenser boiler with this tip - hope it helps you.

air in gas
gas rate low
could be gas valve faulty,ignition transformer,ignition cable.
if there is a spark then its your gas valve,if no spark then check continuity on harness and spark generator,also check earth to appliance
