Question about Karcher K2.26 Electric Power Washer

1 Answer

The engine on my Karcher K2.26 turns on when you turn the switch and continues to run rather than just when you pull the wand trigger. Lower pressure also results.Any solutions?

    This is often a symptom of too low a water supply (inlet) pressure. Does the washer behave the same on a known good water supply pressure?

My Karcher 530M runs ok until I release the trigger, then it will not start again unless I switch and allow the water to run through for about 15 secs before switching on again


Hi Cliff:
My experience is that the pump pressures prevent the engine from starting, so we hold the trigger while starting.
My brother has cut a wedge of wood that he uses to jam the trigger open to bypass the problem. It can get a bit wild if the wand is not secured when the unit is started..

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.

How do you use the tube for the detergent


Put the tube into a bucket with detergent that is recommended for your machine then put the wand into low pressure mode and if it has a valve where the hose connects turn the valve to the on position and pull trigger and watch to see if soap starts being drawn out of the soap bottle if it starts pulling the soap up continue to allow it to flow till you get your part soaked with soap, then let it set for 10 minutes then hit it with high pressure hose to wash off, when it is clean then put it on low pressure and pull hose out of bucket with soap and then allow the soap to be pulled out of tube and until there is no longer any soap coming out then store the hose for use later. some machines have a control valve at the end of the wand by turning the tip or pushing tip in or pulling it out some models requires you to use quick disconnect fan tips to lower pressure to use soap.

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.

Karcher pressure washer trigger problem


The wands that it will not run with would most likley have a little dirt in the tip of the nozzle. This would not allow the water to flow through in turn activating the pressure switch and shutting the machine down

Karcher 2400 psi blaster When you release the trigger it will not pick up pressure when you use it again


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.
