No hot water, all the right noises

Postby Jacoba » Thu Mar 12, 2009 9:57 pm

We have a Worcester Bosch 28CDI - the heating is working but we have no hot water. None of the warning lights are flashing, the flow switch is working and the boiler is making all the right noises but no hot water is forthcoming. Please could someone advise, thanks.

If NO hot water - has someone switched the cold inlet off??

When the system is cold, run the hot tap and see if the central heating flow gets hot, if it does the diverter is at fault.
