Buy a new valve not the kit. One small mistake and you may have problems
all over again and having to but a new valve.

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

How difficult is the job?

Evening people,

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

I have rung up a boiler engineer (the same person whom fixed this
problem 2 years ago) He tells me it's a Valve that has gone.

The price he gave me was 120pounds for a reconditioned part OR
190pounds for a new part both with ONLY 1 years guarantee.

I am quite a competent guy and am prepared to fix my boiler myself.
Can someone tell me what is actually wrong with the boiler and what
needs changing.

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
