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.

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 Honda GC160 5 horsepower power washer with 2400 psi. When its cold it is easy to start but after it has been running for a while the only way to start it is to have the water shooting out of the wand. Once it is hot and running if i stop the stream of water (release the trigger on the wand) then the machine shuts off. It seems like the only way to keep it running is to constantly have water running through the wand. Please help

Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on - off at approx 1 second interval. I suspect that the plasstic oulet tube is leaking causing low pressure leak out of bottom when trigger is actuated and causes pressure switch to cycle when the trigger is released. Any Help? This pressure washer is approx 18 months old!

I really appreciate the help and the information I have read so far. My Karcher K2400HH runs like heck until you release the trigger. Then, if I take the quick-connect nozzle off, pull the trigger and shoot a stream of water, I can then put the nozzle back on and it runs like heck again UNTIL I release the trigger. Then, it is the same process each time I release the trigger. Kind of frustrating.

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.


Sounds like the unloader is not working correctly. Try replacing it and see what happens. ... Briggs & Stratton Prosumer 20324 Gas Pressure Washer
