hot water won't turn off

[Bradley31]

Quick update. The water came on as the timer asked it to, but again the hot water has stayed on even though the timer and the HC60 box have gone off. It is so hot upstairs now as the excess hot water has gone to the Rads upstairs.

The hot water one stays open with the system off and it keeps the boiler going

Wired wrong or prog faulty do you have 240v on the brown to the hot water valve ?

Have 240v And it’s been wired the same as before the fault. this is why it’s been driving me mad lol

Programer sticking needs changing if you remove it from the base plate you should loose your 240v on the brown hot water

I’m guessing the programmer is set to all off ?

If your water is getting excessively hot, it would indicate that the HW valve is being by-passed, the rubber ball in the valve could have perished as they tend to do, they do not last forever.
