glow worm betacom 30 diverter valve

[TFGplumbing]

Got one of these with ch water tracing up the flow when the hw is in use, Iam I right in thinking changing the diaphragm on the diverter valve will solve this? or will the whole valve need to be replaced?

thanks in advance guys & bah-humbug

That's also a sign that the plate heat exchanger could be blocked, is hot water performance affected?

I would check plate first before ordering diverter valve, I had same fault on same boiler the other week and it was blocked plate.

Thanks shaky, whats the easiest way to check the plate on these?

best way would be to whip it out and have a look.

Take a new one with you, sounds like it will be the problem.

Check your temps in and out of the plate heat ex first of all. You'll know if its not working correctly. Check temp rise on nearest outlet and f+r on primary side.
