SOURCE: karcher washer went dead

Dear jimbocom,
The problem is that the spill valve got stuck. When the machine is working and the gun is closed, a valve( spill valve) moves with the accumilated pressure and switches the machine off. So what happened is that when the spill valve did its job, it found no water...and remained stuck. This leaving the machine in an off position. Service and lubrication to the spill valve must be done or completely replacing with a new spill valve. In my opinion you have no serious damage, but this job must be carried out by an expirienced technician.
Regards,
MG.

SOURCE: trouble with Karcher Pressure washer

Dear Pgarciax,
It is important that you must have mentioned the model number of your Karcher. Just the same I can surely say that your machine's fault lies in the "SPILL VALVE"
When the gun is open and pressure is being produced, the spill valve is in a relaxed position. Also it has at the bottom a valve, which when pressure is produced it is closed. If this does not close due to dirt or corrosion, the pessure goes down. Now when you close the gun,pressure forces the spill valve down to close the electrical system. Now if the "o" rings of the spill valve are damaged, the machine will start going on and off while in stand-by. So if you know how to locate the Spill Valve, all one has to do is change it with a new one.
In some Karcher machines there are 2 spill valves. One regulates pressure and the other one is for switching off the machine when the gun is closed.
Low pressure could also be due to faulty suction or delivery valves. Most probably the suction valves.
But when saying that there are short interruptions while in stand by, I stick to the fact that the spill valve needs renewing.
Regards,
MG.

SOURCE: Cant change the high pressure hose on a Karcher

On the Kärcher, you have a bayonet mount at the base of the tip end of the pistol grip. This is where you attach different types of nozzles and gadgets after having removed the existing sprayer tube. Just push in and turn a quarter of a turn, then you pull it off the pistol grip. The hose is possible to remove from the machine as well, an ordinary threaded mount but since you need the pistol grip to regulate on/off this is probably not what you want to do. If the telescopic wand is made by Kärcher it should be very easy to snap it into place just like when you removed the sprayer tube/nozzle. If the attachment was made to fit Alto washers there is an inexpensive adapter that works very well. Good luck!

SOURCE: Pressure hose not working on Karcher pressure washer

A common problem with these is a pressure valve inside the unit that controls the power to the pump. If the unit has not been used for some time the valve can stick.

Does the motor run when you press the trigger?

Please respond and I will advise further. (add a comment)

Karcher Leaking from Back or inside...Help please

Karcher pressure washers are very sensitive to over-winter freezing. The plastic parts break, and you have to replace all of the leaking parts.
You may be missing a locking tab, without seeing the thing apart next to the exploded parts view, it's really hard to tell. Search google for "karcher parts", and put in your model number...

The hose blows off when attached and no water goes into the machine but the engine seems to be running

It sounds like the quick- connect fitting is faulty. That's the fitting on the washer that connects the water hose to the washer. They are readily available at any hardware store or Home Depot / Lowes . Don't run the washer without water going thru it. It could burn out the motor/pump.

No pressure HOSE IS BIG ENOUGH,NO KINKS, FILTER IS CLEAN. TOOK THE PUMP APART AND CHECKED ALL THE CHECKS, THEY WERE ALL OK.WHAT ELSE CAN I LOOK FOR? THE PUMP IS A KARCHER-MODEL G 1800 LB Thanks, Art

Brother Art,

Try this trick; it always works for me. Assemble the garden hose to the washer, install the HP hose, turn on the water. Now, make sure that there is no air trapped in the garden hose. Manipulate so as to direct any air trapped in the line to the washer. Connect the gun and continue to allow water to "free flow" for several minutes. Now, work the trigger, allowing the unit to rise to "house pressure, and then pull the trigger, dropping the pressure suddenly. This displaces any air hidden in the system. Do this several times, and start the washer up. If this doesn't get you up to pressure, repeat the above on an abbreviated scale, and hold the trigger on the gun down while you start the washer. This should do it.
Regards, --W/D--

Karcher Power Washer that surges up and down with water pressure.

Before you start it up:
1. Disconnect the high pressure hose 2. Connect the water supply and turn on 3. Make sure water is flowing through the pump
Start the motor, run for about 10 seconds and then turn off.
Turn off the water supply, connect the high pressure hose, turn water back on, start the motor and away you go.

I can't connect the garden hose to the water inlet. I am using a size 5/8'' hose but it wont connect to the unit. Please help!

Karcher electric pressure washers typically are supplied fitted with the male half of a standard Hozelock connector. You need the female half secured to the end of your hose, and then they just click together.

Pressure surge on and off for 2 seconds w/ new Karcher

It can be one of three conditions,
  1. The water supply in is not sufficient
  2. The pump oil is low
  3. The seals are bad in the pump.
I would check the first one first as this is the most common problem.
The water supply hose should be a high volume hose of at least 1/2 inch but 5/8 inch or greater is best.

How do i connect the hose to the karcher k399 handle

Pop out the plastic tab at the base of your gun (use point of screwdriver/knife).
Then push the hose connection into the gun and push the plastic tab back into it's slot. This will hold the hose in place.
