We have a Karcher G2500VH pressure washer. If you start the engine with the trigger pulled on the spray wand it will run at full pressure until you release the trigger. after that, when you pull the trigger it will not have any more pressure than the water hose feeding it. Does it have an internal unloader valve? What is the part number?

I have the Karcher 2400 psi, 5.0 Honda engine. Starts fine, but when you pull the handle on the spray wand, the pump does not kick in and the water just continues to trickle out of the end of the wand at regular faucet pressure. Occasionally the "clutch" will kick in and you have full pressure, but if it does and I let off of the trigger then chances are that it won't kick in again. has been getting worse for several years.

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

I have a Husky pressure washer with a Honda 2600psi engine. Problem is, no water will come from the pressure hose. I connected the water w/out the pressure hose and water flows thru strongly. I then connected the pressure hose w/out the wand and water flowed thru the hose fine. When I connect the wand and pull the trigger, nothing. I have replaced the wand and that was not the problem. Please help.

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 had 3 Karcher pressure washers all experience the same problem and so have two of my neighbors. Our area has very hard water and it causes problems with the washer not bringing up the pressure when the trigger is pulled (or surges up and down) and the nozzles clogging, etc. The service repair facilities cannot tell me how to prevent this. Many attempts to contact Karcher for advice have been ignored. I have been thinking that perhaps running the engine for a few seconds with no hoses a

I borrowed my neighbor's Karcher Model G 2650 OH (it's several years old). It had the yellow tip already on, but after awhile, I took the tip off to use a different tip,and pulled down the brass coupling at the end of the wand to insert the new tip. The problem is that the brass coupling at the end of the wand won't snap into place around the tip -- so I tried another, and another. No luck. And now the original tip that was on the wand won't snap back into place. HELP! I need to get my neighbor
