Having problems with your Pressure Washers ?

Ok I wasnt satisfied w/ the previous answer so I did some digging. I took off all the hose attachments and drained the line. I then checked for any clogging in ALL the screens. As usual the wand screen was clogged. this is an easy fix w/ a safety pin, but an easier fix is to replace it w/ stainless screen, or alum. The majority of the gunk is Rust. Anyway take the bottom piece off w/ a 6mm. allen key and remove the 5 bolts holding on the casting. (this will expose three pistons on the underside of the motor.) if it dont bust loose use any type of dead blow to knock the seal loose.(should come off easily). Once inside check the o-rings and make sure none were pinched during assembly. Now when I got to this point I started to think,"maybe I'm in over my head". Then I wanted to see if the pistons moved up and down. so I tug on the pull start and she was hydrolocked. so I popped off the spark plug pull a couple of times and notice all was well w/ the 3 pistons, which moved very freely. Then I proceded to put the cast piece back on using a tire tightning pattern. after all is put back together and tightned and turned on, check for pressure if nothing is better I'm sorry. but mine worked and now I'm washing my quad. peace in the middle east, randy
I took the pump off of the motor. Then removed the soap dispenser fitting, 3 piston cap fittings, and then hooked up to the spicket and it helped loosen up the problem.

Troy-Bilt 2550 20293 pressure washer not producing pressure. Worked when last used 2 months ago. Pump pistons are moving up and down when engine is pulled through. Inlet water is flowing through pump but no pressure when engine is started. I have the same problem. Water flows thru the pump when not running, but no flow or goes in by-pass mode when I start the pump. The pump being Troy Bilt Model 020296-01. I replaced unloader valve even. Anything else I can do?


You replaced the unloaded valve. Are you positive you have the unloader screwed to pressure and not turned the opposite way? You will have no pressure if it is adjusted wrong. One other thing I have encountered is that the unloader has a ball bearing ... Pressure Washers

No pressure Gas powered pump is a radial type from DeVilbiss. There is very low pressure, although there is some pulsing from the pumping action. There are no leaks and the supply pressure is good. Pump pistons are in good condition. They seem to be pumping when I had it disassembled and operated by hand. I suspect it is something in the bypass or unloader. Or it may be in the ''easy start'' assembly which I assume reduces backpressure on the pump when starting the engine. Pump has a temperatu

My pressure washer starts fine, shoots water OK. After running for 5-10 minutes cleaning siding I shut off machine. I go to start it again within a minute or two and the thing feels like it's just about seized. If i wait until the motor is completely cool, it will pull start freely and start right up. I think something is wrong with the pump, not the engine.

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 Troybuilt pressure washer which has a Honda GC160 engine. The engine starts easily but quits after about a minute. One pull and it re-starts, then quits in a minute....... This goes on for as long as I want to keep re-starting it. Anyone know what it might be? I pulled the carb off and blew out all of the various ports I could find. I did not remove the carb adjustment screws as I have not had any luck getting them back in place during previous problems with other gas engines.

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.

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.
