... Pressure Washers

I have a KARCHER Model K 2401 which onstart up has normal water pressure rather than the high. I can usually get it to work by removing the tip, pressing the trigger and running some water through without the tip on. The i replace tip and it will usually retain the high pressure. If I stop depressing the trigger I have to go through these same steps. It is like it loses prime. It works well once I get it started putting out the high pressure.

I have Karcher 520m and when you press the trigger you can hear what sounds like a relay engaging but there is no water pressure, then it will fire up and work, but next time you press the trigger the same thing happens, I have been using it on harvested water, but even connected to the mains it does the same thing. Its now got to the stage it doesnt want to work at all.


The issue you are having is with the unloader valve in the pump. Now with the 520m it is a little bit harder to repair than with more gasoline powered pressure washers but it can still be done. It would be easier if I could just send you a email of t ... Karcher 1750 Psi Elec Pressure Washer
