I have a honda 2600 pressure washer. After running fine for a couple of seconds the water will stop flowing out the tip. It is receiving water,but will not flow it to the pressure hose. I even disconnected the pressure hose and no wate was flowing out. When I shut the pressure washer off it would then flow water to the hose again. Please help

depends on where the oil leaks from , normally a cloudy or "grey" oil sheen ,oozing out from here and there doesnt consern me too much , but now the oil running from the big hole or crack in the housing now that conserns me , make sure unit is "primed" with water (small flow from tip with motor off but hose turned on) if still no good then cycle your unloader a few times by tunring the pressure adjustment all the way up and all the way down with water on and motor runninng , this should work unless you have a larger problem

Sounds like a pump failure. Does yours freeze in winter? Need to winterize like cabin plumbing.
Repair/replacement of pump could be close to new unit.

Could also be crack/leak in HP pump. If it were left in cold weather without antifreeze, I'd check there first. Part + labor might warrant new washer if more than a couple years old.
Sorry.

Honda had a problem with the gas cap not venting properly, but commonly it will run for several minutes at a time before stopping. 30 seconds sounds like possible fuel delivery problem like a sticking float or dirty carb jet..especially if you have to run it with the choke on. A bad air filter...very dirty, or oil soaked might do this. Check your oil level. Sitting, oil is a little higher level than when running and these motors will not run if the oil level is too low.

sounds like there is a valve hanging up inside the pump

the carborater may need a dighafram or carborater cleaning of the bowl

have you tried differnt tips?

Pressure washers have a pressure regulator/unloader that bypasses the water back into the intake when you let go of the trigger with motor running. If you let the machine run for long preiods in bypass the system could be damaged due to heating of the water being bypassed. The water is in a closed loop. The as the unloader wears it will tend to want to bypass which is what is happening in your case. Dirt trapped at the tip will cause this also. Install clean tip to solve problem. If clean tip did not help then try lowering the pressure by turning pressure regulator counterclock wise. If problem is gone then parts are failing but keep using pump. Good luck.

Hello:
Have you tried changing the gas, Especially, if it has been in the machine of a while. Also some Honda engines will not start if the oil is low. Also try removing the high pressure hose before you start it? Do not run it very long without water flowing through the pump, though.

Dont use your mouth youll get poisoned, soap will only come out when there is high water flow, ex. with soaper tip (the one with the bigger hole) or no tip. When you have high pressure tip on it will not work.
