The unit keeps triggering the overload button on the powerboard

Need help eliminating the issue with pressure cleaner. I need to bypass micro switch in order to see if the automatic ss valve is the problem or the micro switch . Clear instructions on how l can bypass the micro switch .. Or any suggestions regarding why it's triggering the powerboard

Is this a good question?

Triggering the overload on a powerboard indicates that the unit is drawing too much power.

If the micro switch that you are referring to is on the powerboard, it is there for your safety.

It may be that the powerboard safety circuit is faulty and tripping when it shouldn't but the way to prove this is to try a different powerboard that also has a safety overload switch and not to try and bypass a safety switch. If the new powerboard also trips out then this proves that the first is OK and that it was just doing its job and that there is a problem with the cleaner.

If it is found that the cleaner is drawing too much power then I suggest that you take it to an electrical repair centre for advice and repair. I do not know where you are but most electrical repairs need to be carried out by a licensed repairer.

The micro switch is on the pressure washer.. Has nothing to do with powerboard have eliminated that by trying other boards as well as directly plugged into the wall socket removing all other appliances in order to eliminate that it drawing too much power.. The micro switch is activated by the automatic ss valve when I press the trigger on the gun it activates the valve and the probe activates the switch which then activates the pump/motor to turn on and off.., l need to test the automatic ss valve so that when l order the micro switch I can order that as well..any suggestions welcome


Hi, I got a bit lost. What is not happening? Is the pump not operating even though the switch appears to be operating with the pressure valve? Not having a circuit, if the valve is mechanically operated by pressure and it has a probe that operates a micro switch to operate the pump, then if it is accessible, with the power removed, use a DMM (Digital MultiMeter - Ohmmeter function) to prove continuity from the plug thru the switch operated (can you operate it by hand) to the motor. If you cannot get all the way thru check from the plug to the switch and then the switch to the motor. Or use the Ohmmeter directly across the switch terminals (hopefully there are only the two) and see if there is continuity thru the switch with it operated. If this proves OK perhaps the valve probe is either not moving far enough for the switch to be operated fully or the valve is not operating.

if the valve is electrically operated, with the power removed, connect the Ohmmeter directly across the valve coil terminals and see if there is continuity, or check from the trigger down to the valve etc . You may have to trace it around but then basically trigger should operate valve should operate switch should operate motor, all electrically except for valve operating micro switch, Hopefully I have got it right and that this makes sense.

If you haven't got a DMM they are only about $10 at most hardware stores.
