Boiler running constantly

    Basically what the title says!!

    Got it serviced recently (vokera) as it had stopped working, with an "e041" water pressure fault. The guy from vokera came out and replaced the parts needed and got it working. The problem is it never stops running. Even when the thermostats don't call for heat, all the radiators are turned off and the hot water tank is full, it still runs.

    I turned the boiler from heat and hot water to just hot water. It turned off then. After about 3 hours the boiler was flashing red with "low water pressure fault" "check plant" so I turned it back on to heat and hot water.

    Anyone got an idea what could be wrong because I'm dreading the next gas bill.

    Cheers.

    did you check your 2 port valves sometimes they can get stuck and will cause the system to call for heat constantly

    Is it zoned?

    one of those zoned valve actuators could be stuck open?

    works the other way too if one of them is stuck closed it won’t turn on.
