Potterton Netaheat 16/22 - Pump constantly running?
Noticed this morning, that although the boiler is functioning as it should, the pump does not seem to stop. I checked this by removing the wiring to the pump, however when reconnected regadless of the ignition state of the boiler it seems to be running (so switch off boiler for now since would this not burn out the pump motor?) Any help welcomed.
