I have a power max 155x that won’t fire up the heating following the summer break. Hot water is fine but burner won’t gone on for the heating. Any tips gratefully received!

Presumably you've fixed it by now, but for others reading this your pump was probably jammed from lack of use over the summer.
Free it by taking the big silver screw out and spinning the motor shaft with a small screwdriver.
If the pump is not getting 240Vac then this is usually failure of the central heating programmer.
