Halstead finest boiler no DHW - CH is fine

[mrM]

I have halstead finest boiler, have just replaced the flow manifold/diverter value as it was leaking water.
Now DHW will only come on when I have CH on.
When I turn the hot water tap on, boiler is not kicking in, in the past I would hear a click indicating the micro switch had been activated and now no click.
Please note all the the diaphragms are new and therefore I like to think that these are not the problem, I have not changed the thermoresistor however and instead replaced them with the old one from the on manifold/divertor value.
Advice and recommendation would be appreciated.

Does the domestic flow switch operate when you run a tap.

have you refitted the micro switch assembley back correctly

The issue was indeed the micro switch, it was fitted correctly however the micro switch was not working correctly. Replace the micro switch and everything worked correctly.
