Hello
I've cribbed off this site a thousand time but now I've hit a snag that I can't seem to solve so need to post.
Woke up yesterday morning and the rads were hot. The boiler (worcester 240) was running even though it is not on a timer and the switch was off.
I climbed up into the loft and had a look.
Could smell burnt electrics so switched off the power all stop.
switched back on and saw sparks coming from the righthand (three wires) switch activated by the diverter valve.
Stripped the valve off and the connections were fried.
Got a new (secind hand, both switches) assembly and fitted it.
Now the CH switches on and off on the switch, result.
However when you turn on the HW tap the diverter activates, the switches are switched and the boiler switches off!!!! Not so good.
Any clues?
What is the function of the two way switch? As that was the one that was cooked I'm guessing it tells the boiler to come on when the diverter valve switches it? what is it doing when the divert is closed?
What is the other switch doing? is it a flow sensor? if that was faulty would that switch the boiler off.
One of them switches the pump off I've worked that out. and that one works as you can hear it cut.
