    Hi Mike, pump supply I believe comes from the boiler via the pump overrun stat. to eliminate malfunction of this stat I am going to purchase and replace the stat

    If the boiler is wired correctly then a faulty pump over-run won’t cause your issue as the pump would still have a power source.
    But if the boiler was incorrectly wired originally (boiler could work without issues) then a faulty pump over-run could cause the pump to have no power.
    The pump will always receive a power source from either the permanent live or switched live. But if there’s no permanent live then that could be the problem that’s now been highlighted by a faulty pump over-run stat.
