Question about Karcher PSI Electric Pressure Washer

1 Answer

Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on - off at approx 1 second interval. I suspect that the plasstic oulet tube is leaking causing low pressure leak out of bottom when trigger is actuated and causes pressure switch to cycle when the trigger is released. Any Help? This pressure washer is approx 18 months old!

You gave a very close solution yourself for the problem. But other leakages can cause such symtoms.Forexample a leaking head or a leaking chemical inlet. These can be caused because the spill valve (pressure control valve) is stuck. When this valve stucks it will leave a micro switch ON. So the machine keeps working with the gun closed. This will in turn creat internal pressure and damages the head, valves and chemical non-return and even damage outlet hose. So besides fixing the leakages you must check and service the spill valve. I often replace the spill valve. One must also checks if the micro switch is faulty. Now very important that what you mentioned that the machine cycles at one minute intervals, with trigger closed...this is most probably always the spill valve fault. If you open machine you see a place where there is a wire..this belongs to the micro switch...under you find the spill valve. Intake and suction valves may now also have a fault. Also there are systems with non-return valves at the machine outlet. You have to tackle by elimination. Fix the leakage..then tackle spill valve and micro switch.

Karcher electric power washer480 .pump runs on when trigger is released there are no leaks . Also i can not turn machine off at the main switch.


If you are unable to shut off the pressure from the wand, there may be an issue with the unloader valve that is stopping it from switching into bypass mode when the trigger wand is released. The unloader valve is designed to respond to the spike in pressure created when the trigger wand is released, and to divert the flow of water coming from the pump to bypass the pressure hose and flow back into the intake end of the pump. If the unloader valve fails to switch into bypass mode, water may continue to flow out of the trigger wand. This may also cause damage to the wand. If you are unable to shut off the pressure from your power washer, stop the engine and discontinue use immediately. The unloader valve should be removed and possibly replaced if found to be malfunctioning. The inability to stop the flow of high-pressure water from the wand can be dangerous and should be fixed before continuing to use the machine.

No pressure on my husky power washer 1650


Basic Issues As an electric-powered washer, a circuit overload may cause your Husky 1600 to shut down or prevent it from starting. In this case, check your home's electrical service panel for a tripped breaker or a blown fuse -- the 1600 requires a dedicated circuit rated at a minimum of 15 amps. To prevent a blown fuse, avoid using other large devices on the same circuit as your washer. If you use an extension cord, it must be rated at 15 amps as well. Before moving on to more complex troubleshooting measures, check the gun safety trigger and release the lock if your 1600's trigger will not move. Water Woes Releasing air from the pump serves as a simple fix for low-pressure water output; remove the wand and allow the washer to run as you depress the gun's trigger until the water output normalizes. If your water output seems to lack detergent, ensure that the clear tube is securely connected to the detergent nozzle. Likewise, check the connected water supply and make sure the faucet is fully open and that there are no kinks in the hose to ensure optimal pressure. Using a shorter garden hose makes for stronger pressure, as well -- Husky recommends a hose with a maximum length of 50 feet for a city water supply. Clearing Clogs If your Husky 1600's pressure seems lacking or its water flow is obstructed, clean the nozzle by removing the wand from the gun, clearing the nozzle hole of obstructions with a stiff wire and flushing the nozzle with clean water. Similarly, clean the washer's inner water screen, located behind the garden hose connector, by removing the screen and flushing it with water. This also corrects low or irregular pressure and may remedy a unit that does not stop releasing water when the trigger is released. Model HD1600 features a chemical solution reservoir with a similar screen; clean this screen in the same fashion if you experience chemical intake issues. More to Consider If your power washer issues go beyond troubleshooting basics, contact Husky's customer service department at 800-381-0999. Husky recommends contacting customer service when your 1600 has problems with its pump, bypass valve, discharge valve or manifold assembly, for instance. Because this series of powerwashers was originally offered around 2001 through 2008, Husky's one-year limited warranty no longer covers the cost of replacement parts or repairs.

Pressure washer will not shut off when water trigger on wand is released


Sharon, you first should make sure you have no connection/leaks any where. There is a pressure switch inside the pump, which controls when the motor turns on and off. Leaks in pressure causes the pressure switch to activate the motor. Leaks are the biggest contributor to a cycling machine. If no leaks, the pressure switch is defective. Check the attached links,instruction and guides, Good luck

Stanley motorised pressure washer. Cant get the water to flow


Disconnect the wand from the washer if you get water coming out of the discharge, the problem is in your wand or the line is plugged going to the wand.

Adjust water pump pressure


pressure control valves are non adjustable
They operate to unload the pump when the trigger is released
What can vary pressure is the jet size at the end of the wand
The screw and nut on the valve is only to regulate the stop/start pressure as the trigger is pressed/ released
low pressure at the wand jet can be from low water supply to the pump or pump internal problems

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...


This happens when air gets inside the hose. An air bubble of sorts is in the hose and will not build pressure until you blow the air out of the line. Start the pressure washer, turn on the water. pull the trigger on the gun. It will spitter and spatter and come to a trickle. release the trigger on the wand. Pull the trigger again and it will eventually work it self out.

Pressure washer stalls out when wand nozzle is released


common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.

Karcher 2400 psi blaster When you release the trigger it will not pick up pressure when you use it again


To determine if your problem is due to an easily replaceable part, follow these steps:

1. Connect the water supply hose, the pressure hose, and the wand WITHOUT any nozzle tip.

2. Turn on the water supply, and press the trigger until water is smoothly running out of the nozzle
after any air is all purged out. Release the nozzle trigger.

3. Start the engine, and let it warm up for about 30 seconds.

4. With the engine running smoothly, press the nozzle trigger. The water should flow out of the nozzle (without the tip installed) at a faster rate, while the engine noticeably loads down as it used to do before your "no pressure" problem. If it does not load down, turn it OFF, and disconnect everything, and contact a Karcher repair facility.

5. If the engine does load down, release the trigger, and install one of the nozzle tips (not the black one).

6. Press the trigger, and the engine should load down, and you should have normal pressure from the wand. After you release the trigger and press it again, you will probably again have no pressure, and the engine will not load down. Removing the nozzle tip, pressing & releasing the trigger, and re-installing the tip should give you normal pressure again, but releasing the trigger will cause no pressure until you again remove the tip, press the trigger, and re-install the tip.

This is caused by a bad UNLOADER VALVE, which is located under a black cap with a metal button on it located on the top front of the pump. I don't know if you can purchase the replaceable parts from a Karcher repair shop, but when a neighbor & I took his washer to a repair place, it looked pretty simple to do this repair, and he was charged about $60 to replace a $5 (maybe) part, and it took about 5 minutes.
