Therefore, fault cross validation is carried out by judging whether the reading of the flowmeter is increased or not and whether the water level of the main washing water tank is increased or not.
Secondly, when the main control board 40 sends an electromagnetic switch opening command, whether the reading of the flowmeter is increased or not needs to be judged, whether the reading of the flowmeter is increased or not needs to be further judged, whether the water level of the main washing water tank is increased or not needs to be further judged, if the reading of the flowmeter is increased and the water level of the main washing water tank is increased, the electromagnetic switch and the flowmeter do not have faults, if the reading of the flowmeter is increased and the water level of the main washing water tank is not increased, the electromagnetic switch and the flowmeter simultaneously fail, and if the reading of the flowmeter is not increased and the water level of the main washing water tank is increased, the flowmeter; if the reading of the flowmeter is not increased and the water level of the main washing water tank is not increased, the electromagnetic switch is in failure, and the flowmeter is not in failure.
Then, when the main control board 40 does not send out the electromagnetic switch opening command, it is necessary to determine whether the reading of the flow meter is increased, whether the reading of the flow meter is increased or not, it is necessary to further determine whether the water level of the main wash water tank is high or not, if the reading of the flow meter is increased and the water level of the main wash water tank is high, the electromagnetic switch fails, the flow meter fails, if the reading of the flow meter is not increased and the water level of the main wash water tank is high, the electromagnetic switch and the flow meter fail at the same time, if the reading of the flow meter is not increased and the water level of the main wash water tank is not high, the electromagnetic switch and the flow meter fail at the same time.
