Question about Karcher Garden

1 Answer

My three year old Karcher power washer has suddenly started behaving as if it has lost its power. There is also an intermittent motor noise when I release the trigger. When I press the trigger again the motor noise is constant and normal. Can you help me please?

This sounds like it had water left in it and it froze over the winter. The motot turning on and off signals a water leak on the output side of the pump. You may have a cracked pump housing. Locate the pump and make sure nothing is leaking in that area when under pressure. looh for fine hairline cracks.

Hi, My karcher 5.86 has suddenly stopped working. No power/ noise from washer when power is switched on. Fuse & source is obviously fine. Im going to obtain relevant torx screwdriver this week to open...


If its not the fuse in the plug it might be the on/off switch. I would check switch for continuity with a multimeter to rule it out first.

Karcher K2.94 intermittent pumping and buzzing


try the machine with the lance removed from the gun.

buzzing is usually the noise made by the motor when it cant turn. if the pump start to pruduce pressure but the pressure builds up too high then the motor will stop turning... faulty lance or faulty spill valve (dump valve)

If you have a Karcher then you should always post your machines barcode.
The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....

Karcher K2.54M loss of all pressure


I have seen it before where the little plastic pistons overheat and melt. The unit still runs but with no pressure. I would pull the pump apart and check the pistons.

When i switch my karcher on the motor makes o noise and does not turn


This sounds like you may need a new capacitor. It is not a costly part to get. What the capacitor does is "jump starts" the motor so if it broken the motor will not start.

A test you can do is if you take off the front caseand then set the machine up as if you were going to use it. then when you turn on the machine quickly push the fan blade of the motor with a flat headed screw driver. If this makes the machine start to work, then you know that you need a new capacitor.

Just be carefull when doing the test.

Please remember to thumbs up :)

My Karcher pulses when on standby,stops when i use the trigger,but it also seems to have lost pressure.Is less than 6 months old but have lost receipt!


Is there a leak from the bottom ?
If so Problem, the leak is from the seam of the Manifold housing. There is a small crack in the seam. A design weakness.. A New Manifold Complete Replacement approx. $61.03.
If not you may replace the Pump Manifold Housing from Karcher, or locate a local Karcher Service Center.
If under 1 year old, and you can find a receipt,Karcher will replace the entire Pressure Washer under warranty.
