Heatslave 18/25 not firing.
No heating or hot water but no lockout light and diverter switch is locked in place.
Hot water was scalding hot earlier despite being set at a middling temp on the boiler and now there’s no CH or hot water.
Makes a whirring noise but nothing fires up when we call for heating and hot water.
It’s late on a Saturday so we’re stuck until Monday unless we can figure it out.
Thanks
