The pulsing can be caused by a poor supply of water - check the washer is getting lots of water going in they need a good supply - check supply hose for kinks,etc.

My karcher seems to pulse when on, could this be due to the low water pressure from the hose?


I do not have specific experience of your machine.
However, the high pressure pump will be controlled by a pressure switch on the high pressure outlet to the pipe and jet.
Pulsing (turning off) suggests that the outlet (high pressure) pipe is blocked or partially blocked. Try checking the nozzle and (with the unit turned off) clearing it with a fine piece of wire.
Hope this works

Karcher pressure washer keeps pulsing when not in use and has lost pressure when in use


This can happen if the head of the pressure pump has split. You may need a new head, and to stop this happening again, tie the rigger open with a zippy tie. The water will run all time now and automatically bleed any air form the system. When you want pressure, turn it on at the main switch. This will prevent hydraulic hammer, (when you pull the rigge)r, which is what causes the head to split.

I have a Kew Hobby 80. The output from the lance is not constant but pulsates.


Could be the input water pressure is not sufficient. There is a pressure valve inside the machine that will cut off the motor if input pressure is too low or non existent.

Try a different source for the water input.
