Hi guys, seen some good responses on here for my boiler, and I have an issue with mine.

Noticed yesterday that my boiler was running, saying it was HW going, no flame. All taps were off.

I read about DHW valve (bottom left). The pin came in and out as expected. However, it kept going when stopped. I pushed it firmly and the boiler stopped..? It didn't move, but somehow me pushing did the job.

I tried to get the CH going, the boiler started but the valve didn't open. Effectively just making the boiler the only 'radiator' in the house. It's been a hot summer, and I'm guessing a lack of movement with the diverter valve has made it stick, or maybe it's dirty.

I fancy stripping down the diverter valve and giving it a clean. Anything I should look out for?

I don't think this a PCB issue as I can physically make it stop i.e. mechanical.

Thanks is in advance
