Karcher Answered Questions & Fixed Issues

Sounds like its shot. You can probably buy a replacmentnoff Ebay at a low price.

Actually it's on the box above the bar code. But who still has the box right?

I have one that will shut off pressure when the water supply varies. Check your water tap, make sure all your connections are TIGHT. If not they will suck air and interrupt and pump cycle. Use new hose washers on everything. The engine (mine is Honda) will also buck in response to varying flow demand. It has an auto-close spring/lever to prevent it from overrunning if it loses incoming water. Good luck.

this can be that you need to bleed the system of air or that there is a problem with your trigger gun sticking when you release the trigger. These are two things I would check before you go into the machine.

Check the owners manual for that information. No manual? try https://www.manualslib.com/

Had the same problem and it turned out to be an obstruction in the nozzle and I mean a small obstruction, it looked like an ant leg. I pushed a 1mm drill bit through and now it works fine.

Maybe press regulator was reset before the unloaded was installed and needs to be set at lowest and then increased as needed.

My Karcher has a reset button as part of the cord. If yours is the same, try that

Possibly. The amount of "badge engineering" going on, its possible they are the same machine with a different name sticker. You would need to have both to confirm.

check gfi plug for failure

The trigger valve either needs new o rings or possibly just to be snugged up a bit.

Hot water, not boiling, pour over the joint and then try. I take it the joint is the standard push in type. When re-fitting, a smear of grease around the joint would not do any harm.
