Diagnosing the Procedure.

1. Take off the U shape cover at the back of the generator and plug out the connection wire for controller, then press the “TEST” button.
If the generator can fill with water -> heat up -> produce steam, then press “TEST” button again to stop.
This means that the main circuit board is working properly and the faults should be on the controller part (including temperature sensor), please replace the faulty parts.

Otherwise the faults are in the main board, sub-board, water level sensor, inlet electromagnetic valve or inlet pipelines, please carefully test each part and replace the faulty ones.

2. If the generator can fill and drain out water properly but does not heat up, please check the connection wire between main circuit board and the sub-board, the relays on sub-board and heating elements.

3. If water comes out from the steam outlet pipe seriously, please clean or change the outlet electromagnetic valve.

4. If the system keeps on heating up even when the current temperature is more than 2℃ above the setting value with the indicator on, carefully test the relays on the sub-board and change the faulty ones, or change the whole sub-board.

Please refer to the circuit and connection diagrams for diagnosing and repair.
Do cut off the power supply before repair.

If problems still cannot be solved by the procedures listed above, please contact the dealer.
