I have just noticed that after using the hot water and turning the tap off that the hot water light on the boiler stays on. The boiler stops firing which is ok but there is still something running, like a small whirring noise, maybe a small motor and the hot water light doesn't turn off as normal. Also, at this point I am unable to switch on the central heating. The hot water light stays on and doesnt switch over to Heating and water.
Anyone experienced similar problems.
