Could be allsorts. seals worn. ceramic pistons split, inlet manifold split( frost damage), unloader valve sticking, etc etc.

Put mains water pressure onto it and look for leaks, then run machine and see if it increases pressure, if not i would suspect unloader valve sticking.....

Not very familiar with the 1050 but i'm a service engineer for high press cleaning equipment...

My pressure washer has lost pressure and has water coming out of a small outlet i assume to be a pressude release device;can this be fixed or replaced ?


that's probably the unloader valve all it might need is a quick dissasle to see whats gumming up the works , as all I was able to find for sale for that model here was a new gun and the soap injector for about sixty bucks each , you might have to look around in the Uk for one as that's were there most popular

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.

Karcher g2500vh..sheared off spill valve


I've seen that before many times. If you have removed all the broken parts you can purchace a new spill valve, grease it and install it. If not, you need to remove the pump and sit it brass side up before removing the bolts holding the brass to the aluminum part (you have to do it that way so the oil doesn't spill out. CAUTION: there is some spring tension on the brass head.), find the other pieces of the spill valve, then put it back together. Then you can buy a new spill valve and install it. there are several on-line companys that sell spill valves for karcher machines, but most of then you would need to call to get the part number and price. I'll help you out by giving you the part number.

Part #4.591-040.0

If this helped please rate it.

My karcher pressure washer has lost its water power


I have the same problem. With mine I have to remove the tip that I am using then pull the trigger and then replace the tip and pull and pressure should return. I believe that one of my valves is sticking causing me to reprime the pump frequently. I am trying to clean or replace my valves to fix the problem.

I hope this helps.

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).
