What to do if Stanley ST-175T-KFA-E won't operate and shows error E1?
- AamandabushAug 21, 2025
If your Stanley Heater won't operate, or the motor runs briefly, and the LED display shows “E1”, there are several potential causes. First, ensure the fuel tank has fresh paraffin. Second, the pump pressure may be incorrect and needs adjustment. Third, the spark plug might be corroded or have an incorrect gap, requiring cleaning or replacement. Fourth, the fuel filter or nozzle may be dirty and need cleaning or replacement. Fifth, there might be moisture in the fuel or fuel tank, in which case you should rinse out the fuel tank with clean, fresh paraffin. Sixth, inspect all electrical connections. Finally, the ignitor wire may not be connected to the spark plug, or the ignitor itself may be defective, requiring re-attachment or replacement.
