Will try and clean out the flowswitch tonight when I get home.
If that doesnt do it, then I assume I will have to call out a plumber to check the thermister or PCB 38/40 (?).
Thanks for advice will let you know what happens.
Ideal Combi Boiler Response 80
Currently I cannot get any hot water unless the heating is switched on.
I am assuming the boiler is quite old and was already in our house when we moved in.
I have checked that all the stop cocks are fully open.
The pressure is at 1.5bar as recommended in...
