Having problems with your Karcher K2.26 Electric Power Washer ?

The motor is pulsing on and off without the trigger being pressed

\015 I have a karcher k3.91 and when switched on at the machine the motor starts to pulsate without the trigger being pressed and the is also a significant loss of pressure can anyone help please.\015

Answers :

It is probably sucking air on one of the connections or around one of the fittings at the regulator. You can also turn the pressure up allittle on the regulator, that might stop it also. Make sure the clamps on the hoses going to the regulator is tite. Also it could be that the regulator is just bypassing water and if it has air in it it will pulsate.
I fixed mine works good easy too watch my video step by step i put it on youtube

The electric motor just shuts down, if I take my finger off the pressure and let the water run with no presssure the motor runs fine. My question is this.

I have a KARCHER Model K 2401 which onstart up has normal water pressure rather than the high. I can usually get it to work by removing the tip, pressing the trigger and running some water through without the tip on. The i replace tip and it will usually retain the high pressure. If I stop depressing the trigger I have to go through these same steps. It is like it loses prime. It works well once I get it started putting out the high pressure.
