Rubbish! :( At least now I have some piece of mind that i'm not going mental as it should work but doesn't!

Is it still looking like the control PCB then? or will the lack of continuity on the summer/winter switch on the DHW setting on the main switch cause me problems? Sorry for all the questions, I'm a right wuss when it comes to cold showers! :lol:

I'm getting 50.4 and 53K... Boiler is cold - last time the thermistors played up though it knocked the CH out straight away..

I tried that, still no hot water in DHW/CH position sadly! What readings am I looking for on the thermistors please? :)

I have just metered the summer/winter switch again, I get continuity if I select DHW/CH, but not when turned just to DHW.. Thankyou for all the advice, it's much appreciated :)

The switch i've arrowed below Is this a low water pressure switch? Would that reading incorrectly cause the boiler not to light?

I've put the meter across the summer/winter grey terminals on the main switch, and am getting nothing - there doesn't look to be an actual summer / winter switch as such.. the main switch has either DHW, off or DHW&CH, It was the 2 grey terminals i've arrowed in yellow below I tested...

Further to my above reply, would you think it would be the red ignition pcb? Or the actual main boiler board that's kippered? Would the DHW pressure switch cause the fault too? Thanks!

The wires from the microswitch are ok, I checked the switch at the plug on the board.. The board was my thoughts too, argh! I can't see it being much else with the central heating working ok and everything to the board working too... Thanks :)

Thanks picasso, I've popped my meter across the DHW potentiometer, and i'm getting a variable resistance when i move it so I assume all is ok there? I've metered the microswitch too and that is all ok as well..

Hello :) I'm about at the end of my patience with my boiler. The central heating side of it is working fine, however when I turn on the hot tap, it shuts off the flame and I get no hot water. I've tried turning the selector to DHW only, When I turn on the tap, the diverter valve plunger moves...
