Worcester Combi 30 hot-cold water

[upholsterit]

I have a Worcester Bosch 30CDi and when the heating is off, the water will run hot, just fine.

When the heating is on however, the hot water runs hot then cold, and so on.

I had Bosch come out a few years ago and paid about £260 for a single repair with a 12 month warranty when it was leaking and they put loads of new parts in and it's been brilliant until this new issue.

I've read it may be a diverter valve!

Any ideas?

get them out again then as a few would probably turn their nose up with doing it anyway
