打开高压清洗机电源开关后，机器虽然有高压输出，但清洗效果并不太好。

造成这种现象的原因很可能是：清洗槽内液体温度太高、清洗液选用不合适、高压频率协调没有调好、清洗槽内清洗液液位不恰当等原因造成的。

高压清洗机直流保险丝DCFU熔断故障。造成这种故障的原因很可能是整流桥堆或功率管烧毁造成的或者是因为换能器故障引起的。

打开高压清洗机电源开关时，指示虽然灯亮，但高压没有输出。造成这种故障的因素有很多，它们分别是：保险丝DCFU熔断；换能器故障；换能器和高压功率板的连接插头出现松脱；超声功率发生器故障。

当打开高压清洗机电源开关时，指示灯却不亮。造成这种故障的原因很可能是保险丝ACFU出现了熔断或者是电源开关损坏，没有电源输入引起的。

After turning on the power switch of the high-voltage cleaning machine, although the machine has high-voltage output, the cleaning effect is not very good.

The reasons for this phenomenon are likely to be: the liquid temperature in the cleaning tank is too high, the selection of cleaning fluid is inappropriate, the high-pressure frequency coordination is not adjusted properly, and the liquid level of cleaning fluid in the cleaning tank is inappropriate.

DC fuse dcfu of high-voltage washer is broken. The cause of this failure is likely to be the burning of rectifier bridge stack or power tube, or the failure of transducer.

When the power switch of the high-voltage washer is turned on, although the indicator light is on, the high-voltage is not output. There are many factors causing this fault, they are: fuse dcfu is blown; Transducer failure; The connecting plug between the transducer and the high-voltage power board is loose; Ultrasonic power generator failure.

When the power switch of the high-pressure washer is turned on, the indicator light is not on. The cause of this fault is likely to be that the fuse acfu is blown or the power switch is damaged and there is no power input.
