Diverter valve?

[aggy]

Hi all.
My combi boilers giving me grief.
The heating side works fine but the dhw doesn't. It doesn't light up at all.
How do I tell if the diverter valves working properly?
When I open the hot tap the little pin from the valve pops out and triggers the switch. I can see the pin coming out and hear the switch clicking.
Does this mean its working ok and there must be another fault?
Thanks.

Make and model of your boiler would have been helpful .

I fixed it, it was a wiring problem. I dismantled stuff to try and clean out the heat exchanger but it didn't work when it was all back together.
Cleaning the heat exchanger didn't make any difference to the dhw running cool though.
A clima+ formel 23V if that means anything to anyone.

I took the exchanger out again and cleaned it with some hydro. Loads of fizzing etc. Put it back in, wire the diverter back in correctly this time, run hot tap and the water gets hotter than its been for a while but then the flame goes out and it cools a bit again then fires up and gets nice and hot etc.
Would the rad side of the exchanger being gunged up cause this?
If not what would?
We're in a hard water area which is a bit new for me as in UK I lived in central Scotland which has lovely soft water.
Nice wheels Agile.
