Glowworm Ultimate 40FF water Pump is constantly running?

if you turn your room stat from high to low and your hear it click then it should be working ok

your time clock overrides your room stat so the fault is more likely to be there

as for your pump running after it should have gone off,,, some times a pump over run was fitted that let the pump run for about 10 mins after the timer turns it off ,,,but that ws fitted mainly on low content aliminium heat exchanger boilers and yours is a cast iron heat exchanger

your clock is most likly to be the culprit because the boiler cannot work unless the clock tells it to ,,,also check your clock is mounted properly on the back plate on the wall just in case you knocked it

room stats a very cheap so it may be worth changing at the same time just in case,, there are3 or 4 wires inside so you need the correct stat with the same kind as yours 3 or 4 wires inside you should also use a qualified electrician
