Having problems with your Briggs & Stratton Pressure Washers ?

2-yr old troy-bilt pressure washer with honda gcv160 engine. seems to run well, but when trigger is pulled get full pressure for less than 5 seconds before reducing to house water pressure. when left running, looks a black plastic pressure relief valve starts blasting hot water. appreciate whatever insight you can give. Thx

Answers :

It sounds like an air lock. Try this: With the machine off, connect the hose to the washer and let it run for several minutes to get all of the air out of the hose, and to purge any air out of the pump. Shut off the water, and connect the high pressure hose, but not the gun. Let the water run for several minutes. stretch out the HP hose and make sure that the air is displaced. Shut off the water, connect the gun, and purge as before. Now crank it washer up. As quickly as safe to do so, open the trigger to keep water moving through the washer. It should come up on pressure very quickly. It is better during normal operation to keep water moving through the system. When I am through for a while, I shut down my washer, but leave the trigger depressed to allow the pump to stay full of water, and cool. This prevents further problems when I restart it.

Model 01902 2350 psi . engine runs fine , sprays out nozzle but lower pressure and water sprays out plastic elbow on relief valve , that is supose to **** in soap if used , cant hold finger over spray from elbow , high pressure , took apart relief valve and plastic valves all orings are ok , brass pump seals look ok , all back together , still blows out elbow . ?? plastic spools were out by somebody else , not sure if they are in right , cant find picture to compare .

It sounds as if the non return valve in the elbow is the wrong way around .The o-ring normally goes in first then the ball then the spring. Try it and good luck. ... Pressure Washers

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

I have a Northstar pressure washer powered by a honda GC160 engine. The last time i used it, water leaks from the bottom of the unit, whether it is running or not. When running, the pressure is fine. I have felt underneath and it appears that the water is coming from the second opening from the rear. Is there a pressure relief valve there. I have a manual but cannot find any descriptors for underneath the motor.

This is a piston seal issue. You can get a kit to rebuild the pump. ... Comet AXD 3020 G Pressure Washer Pump

I have an Asko DW1875 dishwasher (10yrs old) which has just recently started having problems. The initial symptom was that during a washing cycle, unit showed '1' and inside became very hot (melting some plastic cups/plates in unit). On further investigation (with diagnostic mode), the dishwasher is filling and draining with no problem. When circulation pump runs there is barely any water pressure in blades (just dribbles out) and water leaks into undertray via a plastic white tab near front (v

Water leaks from underneath the unit. Water only leaks when the pump cuts on (pressurizes). It leaks down on to the hose connecting to the water inlet valve on the right hand side of the unit when looking at the door of the unit. When the unit is full of water and the motor / pump is not running the unit does not leak. This unit is a Maytag jetclean dishwasher Model DWU9200BAB about 12 years old

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 a Whirlpool DUL300XTLQ3 Queit Partner III. The cleaning blades stopped moving-started it-waited awhile-opened it-the blades were in the same position. Took the bottom blade+filter cover off. Then I held down the metal piece on the case and switched on the micro switch on the door to see it running with the door open. The water shot straight up about 4-5" that's it. This does not seem to be enough pressure for the water to get all the way up to the top spinner. Am I looking at a new pump

My sound conditioned Whirlpool dishwasher is real old. It fills up completely with water. It looks like it will overflow, so I stop it. I thought it always started washing from the start. Do they always fill completely up with water, then start washing. I never noticed. I am afraid the water will overflow. Can it? Last time I ran this, it had a real loud motor. I used to hear the motor running from the start, but now I don't, just water filling up to what looks like overflow if I let it. I baile
