1. When the power switch of the washer of the high-pressure cleaning truck is turned on, although the machine has high-voltage output, the cleaning effect is not very good. The possible reasons for this phenomenon are: too high liquid temperature in the cleaning tank, inappropriate selection of cleaning liquid, poor coordination of high-pressure frequency, inappropriate level of cleaning liquid in the cleaning tank and so on.
2. DCFU fuse fault of DC fuse in high voltage washer. The possible cause of this failure is either the burnout of the rectifier bridge stack or the power tube or the failure of the transducer.
3. When the power switch of the high-voltage washer is turned on, the indicator lights up, but the high-voltage does not output. There are many factors causing this failure, they are: fuse DCFU fuse; transducer failure; the connection plug of transducer and high voltage power board loosening; ultrasonic power generator failure.
4. When the power switch of the high-voltage cleaner is turned on, the indicator light does not light up. The possible cause of this failure is that the fuse ACFU is fused or the power switch is damaged and there is no power input.
