Quality Replacement Part with Perfect Fit
I found this company when doing a Youtube search for ideas on repairing my Karcher pressure washer. They had a repair video with the exact model I had. The video was very helpful and the parts I ordered from them fit perfectly and made of quality materials. The parts shipped quickly. I would order from them again. Regards, Chris

Hi. I replaced the unloader valve but still having no pressure. Thanks and blessings
Hector For model number Pressure washer Karcher G2500LH - December 23, 2022

Hi Hector, Thank you for your question. If you replaced the unloader valve and you still have no pressure, there are some other parts that you will need to check to see which one is causing the issue. You will need to check the pump check valve, the pressure spring, the pressure check valve set and the grooved ring. Once you have determined the part you need, please feel free to call customer service. We are open 7 days a week and anyone will be happy to assist you. We look forward to hearing from you!

Pressure washer pressure pulsing very fast with high pressure

William from Greenport, New York

4 of 4 people found this instruction helpful.
Difficulty Level:
A Bit Difficult
Total Repair Time:
More than 2 hours
Tools:
Pliers, Screw drivers, Socket set, Wrench set
Parts Used:
6.365-394.0, 6.365-393.0, 6.288-050.0, 5.332-391.0, 4.580-330.0, 2.884-916.0
1. Purchased all most likely parts likely to cause problem: valves, seals & springs.
2. Disassembled pump. No oil in wobble plate housing - only some water. (Probably piston seal?)
3. Cleaned housings, reused parts with carb cleaner. Added 15-40w oil. Reassembled & installed.
4. Works better than when I bought it, (was r ebuilt unit.)
5. I found seals a little tricky to install as they are flared out & you\'ll probably try to use a screwdriver to install - careful, easy to damage seal.
6.Also, check the spill valve before you remove pump - it can cause erratic (as well as low) pressure.
