Karcher Motor Pulese On and Off

When I use my Karcher washer the motor 'Pulses' On and Off continuously. About one second on then one second off. I have a variable pressure lance and if I reduce the pressure it works without a problem.

What's wrong - is it something easily fixed?

Hi mark, you do have a problem with the lance.
you need to disconnect the lance and straighten a paper clip and insert down the nozzle end.
use the machine to wash the dirt in the nozzle backward down the lance.
Dirt only in nozzle end.
if still no good, purchase some nozzle cleaners and file out nozzle very slightly.

NT48/1 professional karcher not working. Changed fuse in the plug yet still not working. Replaced the filter. Still not working. Could be the motor not working?


Is the motor running? If not, did you check the starting capacitor?
Did you check motor windings for continuity? Did the pump seize? Is electricity reaching the unit - wire ok?

I have a Karcher K3.540 pressure washer. Won't take up detergent and motor pulses ever second if vari-lance increased towards maximim. Motor runs ok at lower pressure but can take 1min to start wh


This fault is within the control head, under the detergent valve is a small spring loaded valve that acts to induce the detergent, this will have failed, the shaft of the component breaks off the disk base leaving a small hole in the centre of the disk. This is enough to allow pressure past the component. The machine will pulse when operated and will not induce the detergent. I've looked everywhere to find this part as I have a karcher with the same fault.

The water must be switched on, and seen to be running freely from the nozzle for a few seconds before switching on the power - suggest you check the fuse in the plug, and then try the above.

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 Power Washer that surges up and down with water pressure.


Before you start it up:
1. Disconnect the high pressure hose 2. Connect the water supply and turn on 3. Make sure water is flowing through the pump
Start the motor, run for about 10 seconds and then turn off.
Turn off the water supply, connect the high pressure hose, turn water back on, start the motor and away you go.

Loss of preasue and pulses in standby mode


Check the oil. This is what happens when it is low on oil with my pressure washer. Kind of a safety feature.

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.

They are sensitive to large extention cords. My father in laws pops reset when a small cord is used. If internally shorted- motor will continually pop the reset even plugged direct to outlet. Check voltage at outlet.
