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

Karcher pressure washer unloader valve sticking? I have the pump shown on page 3 of Karcher manual number 91392030. I removed the unloader valve, but am not sure if I have the entire assembly. I got the top seal and a spring. The bottom seal may be jammed in the pump.

I recently replaced the water seals, V-packing & all six check valves in a CW-3504-4MGH pump on a MiTM 3504 pressure washer that had very low pressure. Usually this would fix most pressure problems on most machines, but in this case it had little to no effect. I suspect that the unloaded is the culprit in this case, but since I have had little experience in repairing unloaders (let alone adjusting them). I would appreciate feedback from anyone that has experience in this area. Thanks

I was given a low hour, 10 year old, CH PW205002LE 6.5 HP gas vertical shaft 2000 PSI/2.5 GPM pressure washer with a Lavor pump. It did not work - no pressure. I found a broken o-ring on the brass unloader valve and replaced it with a ring as close in size as I could find as the part break down doesn't state size. Everything was very clean. I coated everything with silicine grease and reassembled, seating the brass piston? as deep as it would go. I had to press the trigger in order to get the mo

Northstar Hot Water Pressure Washer (model #157322) While using the pressure washer the safety relief valve activated venting steam and hot water from it...

The motor runs fine, but the pressure hose pulsates as if the pump is intermittently making pressure, and the pressure out of the sprayer is about half of what it should be.

I have a HD 2701 DR pressure washer that starts and runs fine and usually works fine the "first" time but if you let go of the trigger and then try to use it again you just get a trickle out of the end of the wand. Usually if you hold the thing open for a while it will kick in (sometimes it takes forever...). Any ideas? It sounds like some of the "unloader valve" problems are similar but I do not see an "unloader valve" in the parts lists for the 2701...
