Yep the microswitch which dictates the flow of water for dhw is what im referring to aswell. It causes the burner to turn off immediately. Even when the CH is on and the burner is already on, as soon as the microswitch is on the burner turns off, but when I release the microswitch the burner...

I tested out the microswitch for the pressure differential. The CH was on, the burner light was on. As soon as I turn on the microswitch which tells the boiler to direct water to DHW, the burner will turn off. Once I release the switch the burner turns back on. Any idea if this is normal or how...

And which microswitch, are you referring to. There's a microswitch for the pressure differential valve and for the diverter manifold. I'd also like to say, I've followed the manuals debugging chart. and through following it. The two final solutions it leads me with is replace gas valve or...

Yes sorry for the confusion. What I meant by firing up is that the boiler makes a whirring noise which means some part of the boiler is reacting to the need for dhw, however the burner does not turn on. There is no flame.

Hello everyone, My CH works fine, but my DHW doesn't. DHW only works when CH is on too. I've gone through and checked my boiler out. The two microswitches work as expected. The pressure is hovering within the correct range. Both the lights to CH and DHW light up when expected. However, the...
