Question about Garden

1 Answer

My Husky Pressure Washer bogs the motor down immediately upon start.

I replaced pressure gun and hose assembly. I also rebuilt the RMW pump with 6 new check valves with brass seats. I inspected the unloader valve and it seemed fine. The pump seemed to have some calcium deposits so I checked and cleaned all the orifices I could. The EZ start ball was stuck upon inspection so I freed that up. After reassembly the trigger being squeezed allows water to flow through nozzle but upon start up of pump, the engine bogs forcing me to shut it down after 3 seconds. The water pressure never changes even after start up. Is the unloader clogged or faulty?

Rebuilding the pump is not easy. Did you use the right seal drivers? Lube the seals when you installed them? Use a torque wrench? But a valve in backwards?

Testimonial: "Hey, Brad thanks for your comment on the husky pressure washer. This is the first time I have looked inside of a pressure washer pump, However, I am an industrial maintenance technician and have rebuilt many types of positive displacement pumps over the years and dealt with many types of configurations. During the rebuild I cleaned the pump and seated the check valves firmly with a light coat of oil. I am thinking that the unloader is not performing properly and redirecting the flow back to the inlet side of the pump but when I checked the spring and orings on unloader it checked OK. It is possible the unloader seat is worn. One thing I noticed is I could remove the EZ start ball and spring and it wouldn't stall motor in this condition but still know pressure change from nozzle......I am still curious as to the solution but these pumps have terrible reviews and aren't worth sinking any more cash into it. I ordered a cheap Himore pump that will serve as a replacement pump. Thanks for your advice."

SOURCE: Ex-Cell VR2500 Builds Pressure but Won't Spray

I have a similar problem and diagnosed it to be a problem with the gun. I spoke to a technician that services this pressure washer and he walked me through all the diagnostic steps. The pump is working because there is pressure being built up and the gun sort of works because you can get water out before the washer is started. The technician said that the mechanism inside the gun is either clogged or broken. I am going to Home Depot or Lowes to purchase a new gun and will try it tonight. Guns are only about $30-40. He said generic is fine as long as the thread matches and PSI is in range. Good luck!

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.

Not sure what type pump you have but you can buy a chem. injector rebuild kit at Pressure washer parts catalog quick links Pressure Washers High Pressure...
If you need to replace the spring then replace the entire kit. Ball, spring and oring. Most pumps that come on the newer TRoy bilts are AR RMW pumps. the parts diagram can be found here at http://www.arnorthamerica.com/manuals/rmw-om%201006.pdf
The parts for a AR chem. injector are

Water goes thru. have hydrulic oil to level. gun semas to stick on. NOT GETTING ANY PRESSURE AT NOSSEL.


Hydraulic oil?
Is this a pressure washer?
Pump should be half full of SAE20 or SAE30 non-detergent motor oil.
Engine should have 10W30 motor oil.

If you have a pressure washer ... and not water is coming out end of gun:
Take all hoses off machine.
Look at incoming water hose connection.
The should be a filter washer.
Clean or replace filter washer.
Hook up water and turn on water.
Water should come out other side of pump.
Turn on power washer and see if water coming out of pump is pressurized.
Now hook up pressure hose without gun.
Turn on pressure washer and see if water comes out of hose and is pressurized.
Finally, the gun may be bad.
We used to replace guns when they went bad.

My pressure washer is a G 2500 oh n i have no pressure coming out, it turns on but no pressure.


Good news, your engine runs
But your pump may be bad

Here's how to test your pump
Check oil as outlined lower down
Disconnect the washer hose and gun
Connect water hose and turn on water and water should pass straight through the pump
Look for clogs in the hose-end where water hose connects to machine

Turn on machine and see if water shoots out pump
If water shoots out of pump, but no water shoots out of gun, then you may have a 'mud-dobber' wasp clog in your washer line or gun

Look for clogs in the end of each water connection.
Now connect washer hose without the gun, tun on the machine, and see if water shoots out of washer hose
Finally, the gun trigger mechanism may be bad
I don't know which gun you have ... but we replaced guns on our machine now-and-then ... google-search power washer guns for a replacement

Check your pump oil
Pump oil is SAE20 or SAE30 non-detergent motor oil
Pump should be no more than 1/2 full of oil
Use plastic hose to drain pump oil
Do not turn machine on its side or turn machine over or engine oil will run into carburetor

My Husky pressure washer 2600 psi powered by a gcv 160 Honda. Engine starts no pressure other then from water source and soap is not being dispensed


It sounds like the (RMW 2.2 G24) pump has gone out. Mine had this problem after about 6 hours of use. I was able to order a new pump for around $160.00, and then installed it myself. Go figure it was just out of warranty. I think my next pressure washer will be one with a professional pump as I was told the one on my husky is only rated for about 40 hours of use.

No pressure


It is probably air locked....Here's what you need to do. Connect the garden hose, and HP hose, but not the gun. Turn on the water, and let it run while you make sure that there are no high points in the garden hose that can trap air....Work the hose so that any air is displaced through the pressure washer. Continue in this manner through the HP hose. Shut off the water and connect the gun. Turn the hose back on, and operate the gun for several minutes, pulling the trigger and releasing. This alternately allows the water pressure to build up on house pressure and then to depressure, pulling residual air from the system. Release the trigger, and start the machine. Usually, this is enough to get full washing pressure. If it is very difficult to start, you can hold the trigger down on the gun and pull the start cord at the same time. Holding the trigger down acts as an unloader, making the starting easier.
Hope that this helps, --W/D-- please feel free to rate this solution! Thanx!
