hi, its that time again think the 3 way valve is stuck ?
i have a oldish myson economist boiler with a potterton e2000 controller. we always use the controller as when we need hot water and cent heating. but when i try to switch the heatin on it doesnt turn on ( it did kick in after 3 hours) just think the 3 way valve is not turning because the hot water is ok. i have replaced this valve twice over the past 10 years , any tips etc ?
