If you're compotent
Step 1
Check live, swl and neutral incoming are correct and pump feed out is correct, note readings!
(Isolate power)
Disconnect and isolate your Switched Live swl feed at the boiler terminal
(Power on )
Does it still make the noise at the same time as before?

What do you mean by no demand?
What diverter do you have?
