Vaillant thermistor fault
Vaillant ecotec plus 418 from about '07 or '10 or thereabouts. Pump stopped running, boiler gave error codes
F22 dry fire F72 NTC thermistor value out of range Pump sorted, but boiler won't run reporting F72. Thermistors measured at 12k & 12-13k - I can measure them more accurately if needed. Anything I should know or check before getting replacement thermistors? NT |
