First thing is remove the water supply house and check the water screen for clogs. Remove the hose washer and pull the screen out. Wash and clean the screen then re-install. Make sure your using a 5/8" hose as a supply hose and that the water faucett is turned all the way on.

If after all of the above it still has low pressure the unloader valve is most likely corroded or has debris in the seals.

Download this parts manual The unloader / thermal valve that is supposed to reset is Item(s) 9 {Valve 60 GND} and 12 {Spill Valve} of detail A on page 11. The spring, seals and housing need a good thorough cleaning to get high pressure. If the seals are damaged they will have to be replaced. Lubricate the seals with lubriplate white grease No. 105 before you reassemble the unloader valve. Grease link: http://www.lubriplate.com/webstore/default.aspx This grease is at any automotive store.

blocked pressure hose or blocked nozzle at the end of the wand
it is controlled by a pressure relief regulator which quite often plays up.

IT HAS PRESSURE BUT IT PULSATES INSTEAD OF STEADY SPRAY


I have same model with same problem. Tried the easy fixes:
unloader valve lube and clean, inlet water sufficient, and nozzles and hose are fine. Broke down pump and called for parts (about $50 for 3 inlet valves and some seals) hopefully this will fix it. Mine has been used in my business pretty hard for a few years, so not bad.

I own a Karcher 3000 pressure washer. There is no water pressure. I've checked the obvious...hose to house, kinks, attachment is tight....Enging runs, no water pressure.


I had the same problem. On the top of the pump there is a little nickle colored button cap. It is attached on both sides with a screw. What this actually does I don't know but when I took it off with the motor running and put my finger over it the pressure come up. I also discovered that having the motor running and taking the nozzle tip off and pulling the trigger would clear the pump to work until you let of the trigger again. Weird but it works for me.

Karcher 320H i have the same pressure coming out as i put in from the tap, the motor is running ok


You have an air lock in the pump and or piping.
  • Open all drain cocks and remove the spray hose
  • Connect the inlet water hose and turn it on slow
  • allow water to run from all open ports for 2 minutes or so
  • leave the water running - close drains start motor
  • Shut down reconnect spray hose restart
  • You should now be smiling

Karcher k3.86 motor runs but has no pressure when trigger pulled, motor doesn't go faster.


Could be a pump, but most likely the unloader valve is stuck open. After replacing/repairing the valve, do the following to prevent it in the future: after finishing using it, unhook both hoses and pull the start cord on the engine several times to empty the water from the pump and valves. This is especially necessary when using hard water.

Have honda karcher 5.0 pressure washer and i cant get it to spray any water or pressure out the gun at all? Why??


Hi,

That is a on going problem with power washers the pump not working, than works sporadically. the main cause is leaving the pressure hose hooked up to the machine over a long period of ,not draining hose & machine, in the winter time the hose & pump willfreeze causing hose & pump to expand and burst. build up of calcium deposits from hard water clogging up pump nozzle,valves in the gun handle,clogging hose fittings and screens.one of these has to be your problem.you can find a parts brake down at KARCHER.COM.orRJ BOWERS.COM . and manuals,these are good info,sites,hope this helps, MrFixIt,oh could you please rate this solutions

If it is not leaking water anywhere and the nozzle is OK then go HERE
Turn it off and shut the water of. Go to pate 2.1 of the manual
Carefully remove part #2. Pull out part # 1 and make sure the O-rings are in good shape ad are lubricated with a good waterproof grease. Re-assemble and try it.

Thanks for contacting Fixya
