Why does the motor run when I do not pull the trigger of the gun after the high pressure washer is turned on? The motor is supposed to run only if the trigger of the gun is pulled and shuts off when the...


When water is running through system, the motor has to run to keep the pressure built up. So, if the water is leaking out, the motor think it needs to keep running to keep the pressure built up. The leak needs to be fixed to the motor will not run constantly.

What is a bypass unloader


According to epowerwash.com:
"The unloader valve diverts water flow into bypass when the trigger gun valve is closed. Unloaders may be designed to respond to either an increase in pressure or a change in flow. The unloader valve may also be used for variable pressure adjustment."

650 Brute Pressure washer, wayer comes out of nossle for about 3 seconds with the correct pressure, then stops, after a few times wayer is warm from wand


Leaving it outside may have broken something inside as water freezes, it expands a lot. The wand is unlikely to be the problem. Your problem is indicative of a water supply problem. Some hose fittings has a non-return valve in the middle, and I have seen these foul the fitting on the power washer and cut off the flow. The pump is a simple centrifugal pump that spins very fast. This is why the water is getting warm because of friction. In normal circumstances, the water running through it cools all the parts.

Karcher k1 leaking from inside casing.


The most likely issue, which seems to occur alot with karcher, is a cracked water pump. What happens is that as you release the trigger on the handle, the rise in pressure should cut off the motor, but as it also cuts off the water flow at the wand end and the motor spins a few more revs until it stops, then there is a huge pressure glitch which blows apart the weak plastic pumps that they use. Since the plastic cracks it is very difficult to repair and the only option is to go and buy another. BUT...this time tape up the trigger on the handle so it is always on and then it won't blow itself up. Just use the unit on/off switch to turn the motor on and off.

Do not know how to work power washer


Dear Carrie688,
I cannot for sure understand your problem. You say, you do not know how to WORK power washer. Does WORK mean FIX...or USE???? I will assume that you wish to know how to use it.
First without water connected and without gun connected...switch on the machine. If it turns, then this means the electric motor is OK. Now connect the hose and gun. Connect water supply. Now always start the machine with gun open. This will help to remove air from system. When pressure builts up, close gun, and machine must stop instantly. If machine does not stop, open the gun again and switch off the machine. If the machine continues working when the the gun is closed, this will result in a lot of damage. I do not know what model you have, because also there are old models that when gun is closed, the machine keeps running. I assume your model is recent. So the machine will stop when gun is closed. Now when finished, switch off machine and electricity. And most important release pressure from gun. Do not store machine with pressure still in it. This will damage machine and it is not safe.
Now if you have detergent, this can only work on low pressure. There are bigger machines that detergent works on high pressure. But the normal system is that detergent works on low pressure. Also before storing, pass fresh water to remove all detergent from pump of machine. Never store a machine with detergent in its system.
Regards,
Fulltech.

Karcher/Winner 11 - motor pulses when hose is not operating


Hi, I had the same problem, Replaced the O rings and the rubber seals and cups inside the pressure washer and eventually the hose itself burst. Turns out the hose was leaking, internally between the inner sheath and the outside plastic cover, for quite some time and this caused the pulse. New hose and pressure cleaner is as good as new.

Need new gun and connection to gun


The DuraBuilt and Coleman pressure washers have a gun that tends to leak through the plastic clyinder wall that holds the plunger that moves with the trigger. You won't see the holes, but if you remove the upper half of the housing, hold the plastic tubes in place with one hand and turn on the water, not the motor, you will see water shooting through the wall.

Amazon sells an exact replacement gun and hose. FAIP PowerWasher Replacement Gun and Hose #80012. Mine does not leak at all and was $29 shipped.

Powermate pressure washer Model PW0872400


pressure washers has this pressure switches where in as you press on the trigger, the washer works and if you release it, the pressure would build up high and it would trip this switch to turn off the motor or deflect the water to the by pass hose ( if the motor is not stopping) then as you press again the trigger, water should come out of the gun again but would not,

i have encountered the problem is in the pressure switch, even the pressure went down, sometimes it wont close the contact then the motor wont run ,

if the motor is continously running, then the trigger switch is the problem, the pressure excerted on the switch is so high that even if you press it , it won't open up to release the water.

what i can suggest is to tie the trigger in the gun so that it is always pressed and then just unplug the unit if you want to stop using it. it is an inconvenience but it will work.

or, open the gun and see if you can figure out why pressing the trigger would not open the switch.

another option is you can lower the pressure of the washer if it has an adjustable pessure controller. by lowering the pressure might open the switch when ever you press the trigger.

i hopw i was able to fix...

good luck,
