SOURCE: Karcher HD 655 S Does not come up to full pressure

yes...check the check valve. A one-way directional valve, this part is also known as a DUMP valve. It opens when too much pressure builds in the hand wand (when not spraying water) in order to protect the pump, by returning the high pressure to its source reservoir. I suspect the DUMP valve is stuck in open condition (or nearly open).

Karcher k3.00 lack of power


Are you using the same water supply as before when you had good pressure? Some house water lines have pressure reducers to protect your pipes and appliances. This can restrict the water flow and reduce the pressure the machine develops. If the flow surges (good, then weak, then good etc) you are not getting enough water to the pump. Try a larger diameter garden hose (5/8"). If you know where your water line enters the house, try the hose bib closest to it. Often times it is at street pressure instead of (reduced) house 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.

My Kärcher K2.080 pressure cleaner (1450psi /


According to my search, Karcher has a 2 year warranty on this product. If you can get the serial number and model number off of it. They should be able to identify when it was made and then can honor that warranty. Otherwise the pump seals appear to be damaged by your description of the problem. Hope I've helped.
Best, Mark

Motor running, water supply adequate but when


clean whole water supply and outlet from all debris, clean inlet filter as well. connect water and pressurise washer, pull trigger and wait about 3sec for pump to activate, if pump do not activate adn you have pressure from nozzle as it will be from main, this determines pressure sensor (it is extremelly rare for pump itself) is damaged.

check if you have still warranty,this will qualify as warranty repair, if warranty is expired, pressure sensor need to be replaced.

if you find my advice useful, please do not hesitate to leave your remarks and vote for me, thanx!

Karcher G2600 VH - low water pressure


If the spill valve activates is "spills" water under the washer. There is a restriction or the pump has become inefficient and will not pump the volume and pressure it should at full RPM.

Pressure surge on and off for 2 seconds w/ new Karcher


It can be one of three conditions,
  1. The water supply in is not sufficient
  2. The pump oil is low
  3. The seals are bad in the pump.
I would check the first one first as this is the most common problem.
The water supply hose should be a high volume hose of at least 1/2 inch but 5/8 inch or greater is best.
