Worcester 24 cdi HW?

It is definately the diaphragm in the diverter valve, but just get a new valve, don't get the repair kit, not worth the hassle and almost definately won't work.

I did mine a few years back. Order new seal kit whilst you're doing it, o-rings and fibre washers, take your time, drain system, turn taps off at back.

Did you solve your problem? What was the solution?

I have the same problem since Thames Water installed a water meter 2 days ago...
