Worcester-Heating on - on its own own

[ikelsall]

Hi
A Worcester combi boiler (5 years old) constantly firing up for 2 mins etc . Radiators can get slightly warm and heating symbol shows on control panel briefly. Heating won’t turn off sometimes

Worth paying an engineer or take the hit on small amount of extra gas it’s using ??

Ensure it's in Eco mode so it won't fire intermittently to "preheat" the water - there's a cop out!! If that is why it's firing then your bypass is "passing to the heating or the plate is blocked. If it isn't the eco being off, it's getting a demand from somewhere. AGSR Engineer is your safest bet
