Hi! robcarroll
Did you purge the air from the pump before starting the motor.

To determine if your problem is due to an easily replaceable part, follow these steps:

1. Connect the water supply hose, the pressure hose, and the wand WITHOUT any nozzle tip.

2. Turn on the water supply, and press the trigger until water is smoothly running out of the nozzle
after any air is all purged out. Release the nozzle trigger.

3. Start the engine, and let it warm up for about 30 seconds.

4. With the engine running smoothly, press the nozzle trigger. The water should flow out of the nozzle (without the tip installed) at a faster rate, while the engine noticeably loads down as it used to do before your "no pressure" problem. If it does not load down, turn it OFF, and disconnect everything, and contact a Karcher repair facility.

5. If the engine does load down, release the trigger, and install one of the nozzle tips (not the black one).

6. Press the trigger, and the engine should load down, and you should have normal pressure from the wand. After you release the trigger and press it again, you will probably again have no pressure, and the engine will not load down. Removing the nozzle tip, pressing & releasing the trigger, and re-installing the tip should give you normal pressure again, but releasing the trigger will cause no pressure until you again remove the tip, press the trigger, and re-install the tip.

This is caused by a bad UNLOADER VALVE, which is located under a black cap with a metal button on it located on the top front of the pump. I don't know if you can purchase the replaceable parts from a Karcher repair shop, but when a neighbor & I took his washer to a repair place, it looked pretty simple to do this repair, and he was charged about $60 to replace a $5 (maybe) part, and it took about 5 minutes.

The machine has a pressure leak. Check for a cracked controll head or either a leaking outlet elbow. The machine will short cycle if the holding pressure can not be maintained

SOURCE: Pressure is fine when first started ,if trigger released no Psi

Your uplift injector valve in the water pump is sticking. You need to remove this part. Lube the top o-ring only with a water proof grease. Reinstall this part. You will be up and running again.

You need to use needle nose vise grip tool to easily remove the valve. You need to grind down the vise grip tool to fit the opening where the valve is installed.

To prevent this problem from reoccuring use a pump guard additive.

These units have pressure valves that automatically turn off the pump once the pressure is high enough. The pressure switches do fail and sometimes stick and act as you've described.

Pressure washer will not shut off when water trigger on wand is released


Sharon, you first should make sure you have no connection/leaks any where. There is a pressure switch inside the pump, which controls when the motor turns on and off. Leaks in pressure causes the pressure switch to activate the motor. Leaks are the biggest contributor to a cycling machine. If no leaks, the pressure switch is defective. Check the attached links,instruction and guides, Good luck

What is this problem - Karcher 3.86 electric pressure washer: humming noise, plug gets very hot, then unit shuts down?


Your pressure washer is either not fitted with a run/stop device in which case like mine you have to switch off within a few seconds of closing the trigger. Check your model features?
The humming noise is the motor stalled out against the pump because there is nowhere for the water to go. The shutoff is caused by the safety overload switching off after overheat.
Or, it has a pressure operated run/stop which is not working. Because water and electricity don't mix, I would suggest getting more specific help. You can download Karcher manuals /spares lists online from Karcher specialists but remember electricity is the silent killer.

My electric Karcher pressure washer does not shut off.


this can be that you need to bleed the system of air or that there is a problem with your trigger gun sticking when you release the trigger.
These are two things I would check before you go into the machine.

Karcher K2.36 motor cut out and won't restart


Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.

Pulsating when idle


The motor doesn't pulsate when you are spraying and pulsattes when not spraying is normal otherwise the pressure will just keep building and burn out the pump. However, if you are not using the sprayer right away then the unit should be shut off until your ready to start again.
I hope the answer is helpful, please rate if the answer has helped in any way. Good Luck and have a great weekend.
