The cart body makes this process a little confining but it can be carried out without removing the pump from the motor.

  1. Refer to assembly 9 in the diagram. Remove the splash cup by working the push-on nut off the top of the cup.
  2. Remove two Torx fasteners (13) and twist the nylon valve retainer gently while pulling up to remove it. Be aware of the small parts under the retainer.
  3. The objective is to get the valve (12) out of the bore (A). Connect the hose and wand to the pump, make sure the wand valve is closed. Connect the water supply to the pump and turn on the water flow.
  4. Place a shop towel over the valve bore and with the throttle in the off position, pull the start cord briskly several times to see if enough pressure builds to pop the valve out of the bore. If not, set the throttle to low and start the engine. Unless the valve bore is really corroded, this should pop the valve out.
  5. If this process fails, you may have to unmount the pump and employ a more brutal approach that will likely require a new valve.
I have worked on my washer for the last 2-3 years to keep it going but I've opted to replace the pump this year. My replacement is an "AR RMV2G25D" (~$170) .

After removing the unloader valve and cleaning i


If you have pulsating usually you have at least one of the six check valves stuck open, so you're only running on two cylinders. You might have got some of your plumbers " grease" in the check valve. (Do you mean pipe dope?) three of the check valves shold be accessable from the outside of your pump but the other three are inside. You can get parts for your unit from www.pressure-washer-parts.com

Clean and unloader valve on Karcher hd3500 pressure washer -intermittent pressure on and off. Cleaned inlet screen. Think unloader valve is is under pressure knob? Will cleaning help?


Hi:
Cleaning it is not enough. You need to make sure the o-rings are in good shape and grease it with a very very good waterproof grease. Here is a schematic of the pump. The unloader is parts 7 to 13 on D-2

No pressure / Karcher G 2400 HH


Hi ruthkapres:
Here is a diagram. The unloader/spill valve is #12 on page D2 or F2 depending on your model. You must pull it out, inspect the o-rings for dents or tears and make sure the valve is lubricated with a good water proof lubricant.

How to clean unloader valve..


The Karcher K2400HH and G2400HH do not have an unloader valve, they have a spill valve which is located under the black cap on top of the pump.

The spill valve needs to be removed and the side walls of the hole it sits in need to be wire brushed to remove deposits. then you can put it back in and put the pump back together.

Pressure washer that leaks oil through the air breather


Most likely your air filter is plugged or dirty, or the crank case vent valve needs to be cleaned.if it still does it check that the oil level is at the full mark, if overfilled it would cause the same problem.
