    My Warmflow boiler with a Riello 40 pressure jet burner has been fine for 18 years. It is controlled by a lifestyle programmer.
    Now it will not power up. Turning on the power at the fused spur supply results in a blown fuse. A multimeter across the boiler supply terminals gives a reading of about 30 ohms. Seems a bit low? No other obvious problems with the control box, capacitor or wiring. What sort of resistance should there be across the motor windings??

    Any ideas? Help!!!

    your problem can be with anything that is switched on at the same time as the burner; pump, motorised valve, thermostats etc. isolate the boiler and see if fuse blows. The burner is the last in line. To test the motor, disconnect the wire from terminal 6 of the base and put it to the live feed without the control box in place.

    If you think the fault is at your boiler Del & you have a multimeter, have you tried a simple continuity test on the L or Sw/L to earth, on the appliance only. If the boiler has a faulty component that's shorting, that'll pop your fuses.

    Most likely cause is usually the central heating pump.

    Disconnect that for a start and go from there.
