I can confirm it is a Vuw 242E model after opening up the facia of the boiler.

How difficult is the job?

What, learning not to top post ?

Evening people,

I have a Vaillant Vuw 242E/282E. The hot water only works when the
heating is switched on.

reading up on threads some people suggest diverter valve or diaphram
and a quick search for part prices tells me my boiler engineer is
ripping me off!

If it is the diverter valve diaphragm split, you can get repair kits for
10-20 quid, but you really have to take note of exactly how you pull it
apart to get it back together again

It could also be the switch on the motherboard having gone high
resistance or some other such fault
