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

I had a 'pulsing' Karcher K3 that I was determined to repair and ended up changing parts in order of known failure points until the problem was cured.
Firstly I changed the output elbow (Plastic and known to crack due to frost) No difference.
Then the pump head (Again, plastic and frost susceptible) No difference and expensive.
Then the input elbow (More plastic BUT comes with a small red capped valve)
It worked!
The final solution for me was the small red capped valve, assessable inside the input elbow with long nosed pliers.
In reality, although an easy fix, the machines are VERY poorly made.
Good luck to all in their repair endeavors :-)

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

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.

This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.

No pressure on certain settings


Dear Osville,
It is not clear what type of lance or nozzel you have. You said that the machine works fine with the circulating water jet(the turbo). So it seems the machine is fine. I do sometimes service variable nozzels and variable lances. But the best solution is to replace nozzels and variable nozzles and lances with new ones. Regarding the fan spray setting it could have no pressure because it might be in the chemical setting. The chemical setting lets out a fan shape flow of water, but with less pressure. The chemical system only works on low pressure in domestic washers, that is why it needs a low pressure flat spray. The pencil jet has 2 jets comming out because if it is a lance or nozzel with ball bearings, these ball bearings must have stuck in a wrong position. Also 2 jets can come out, due to a damaged nozzel hole.
Altogether, the best advice is to buy a new nozzel or lance...which ever your machine uses. All Karcher machines have their own specific nozzels, lances and high pressure hoses. You cannot change these from one model to another.
Regards,
Fulltech.

Hi,karcher hds hot pressure washer now pressure when you pull trigger and pulses.


what you need to do is, take the screw fitting which goes to the water tank off, then the one that goes from the water tank to the pump head .
then put the one that was in the first place going to the water tank on to the pump and force feed with water.
see if you can see water leaking from any where seals hose.
try running the machine to check the pressure.
if water leaking from pump head you need seals.

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.
