No hot water
Last week I had no hot water but heating, after resetting the system I now have heating but no hot water.
I've sent countless emails and voicemails to support but had NO reply.
Can anyone here shed any light?
Boiler: worcester bosch 30cdi
and ai believe i have an unvented hot water system.
Below is a picture of behind the extension kit.
Jumper was put into position 2 and no wires were changed
