I have karcher 620m pressure cleaner. Motor runs constantly but no pressure, just a thin stream of water which is just the pressure from the hose. Any idea what's wrong?

Try this. While pushing the trigger of the gun, turn lance fully anticlockwise and then turn back fully clockwise.

Washing machine will not stop filling up with water

Is the machine siphoning off water as it fills? If it is check the height of the drain hose and make sure it is above the height of the normal level of water that would be in te drum when washing, if the hose is to low the drum will siphon off the water on its own and continue to fill. If the machine is not siphoning off water while filling then you may have a blocked pressure hose or the pressure hose bottle may be blocked not allowing the pressure switch to activate. there may even be a small hole in the pressure switch hose. Check the thin pressure hose that goes from the bottom of the drum to the pressure switch.

Kenmore Elite HE4t was flashing F/H and now it wont function at all. I have clothes I can't get out of the washer. Can you help with this?

An FH error is displayed when either no water is detected entering the machine or... water has entered the machine and the water level pressure switch did not trip when water level was reached.

Causes are clogged inlet water screens in the inlet of the water valve. Turn off the water, remove the hoses, use a thin knife blade on the outside of the screens and pull them from the inlet of the water valve. Wash them under slow running water by rubbing them with your fingers on both sides of the screens. Re-install them, reconnect the hoses and turn on the water.

There is a flow meter in-line of the tub fill hose from the inlet water valve to the tub that senses water flow that can cause this error.
Flow meter: (picture)

As far as the water level control pressure switch.. there is a thin 1/4 inch rubber tube that runs from the pressure switch to the tub. If that tube gets clogged or a hole in it the pressure switch fails to function normally. The remedy here is to remove the hose and clear any obstuctions withthe wash tub EMPTY. If the hose is removed while there is water in the machine it can overfill or not sense the proper water level.

Try draining the water from the machine if there is water in it by lowering the drain hose to the floor and catching the water for disposal. Then unplug the machine for 10 minutes and plug it back in. See if you can then open the door by pressing cancel / end cycle . If not respond here and I will help you get the door open.

Replaced the Pump/Motor now the LD/OB messages are gone, however, now it won't fill the tub and after a little while I get the LF message. Water will run through the detergent and bleach dispensers, but...

LF Error code: LF stands for long fill and occurs when the water level does not change for a period of time after the valves are turned on.

All washers are designed to operate with a water supply pressure of 20-100 PSI. When the pressure drops below 20 PSI the washer can have the following problems:

* Slow Fill- low water pressure reduces the speed at which water flows into the machine.
o Verify the pressure at all other water sources in the house (i.e. sinks, showers, etc..). If you find other places where the pressure is low, the problem is not with the machine but with the water supply.
* Continuous Fill- The valve may not fully seat under 20 PSI which would allow for a constant flow even when the machine is not supposed to be filling.
o Contact the water company to verify the pressure being supplied to the house.
* dispenser- Needs a minimum amount of pressure to function. May dispense constantly, at the wrong time, or not at all.
o A plumber may need to be consulted if the pressure is found to be too low.

Things you can check :

* Are the Hot and Cold water faucets turned on
* Are the water hoses kinked
o Make sure all the hose are straight and able to flow water
* Are the screen inside the water valve plugged
o Inlet valve should be free of debris and rust.
o Turn off water and remove the inlet hoses from washer.
o Remove any accumulated film or particles.
o Assure rubber washers are in the end of each inlet hose.
o Reinstall hoses, turn on water and check for leaks.

Error codes can be caused by a Power Surge or other electrical anomaly,attempt to return the washer to operation by following the Hard Reset procedure below.

1. Unplug or turn the circuit breaker off for 30 seconds.
2. Reconnect the unit to the power source by turning the breaker back on or plugging the unit back into the wall outlet.
3. Press the Pause/Cancel/Stop button twice to clear the display.
4. Start a short cycle to check the operation of the machine by selecting a cycle and pressing and holding the start button until the machine starts

Water does not stop running into tub.

If it is filling even with the machine turned off the water valve is stuck and has to be replaced. If it fills constantly when used the pressure switch hose could be blocked or the pressure switch is bad.

Karcher Pressure washer

don't know if this will help, but when I use mine, to start the pressure up I have to turn the nozzle to fine spray then turn it to the power spray and it works every time, shouldn't have to do this but I got it for nothing.

Got a karcher 410 water pressure passed down to me without directions need help working it

Fairly simple to opperate. Connect water supply hose. Connect wand hose. Plug in, turn on water supply and turn on. Then squeeze the wand handle to spray. With mine, there are times when the unit looses pressure, but if you leave it running, it seems to recover. Also note that you can turn the flare at the end of the wand for a soft stream versus pressure spray. I have had mixed results with the pull out clear tube that is supposed to siphon liquid soap into the mix.

Drain pump runs constantly:Error code E02

Suggestions: First see that the exit hose behind your machine is inserted at a particular height, ie about 3 feet above ground level, then into the standpipe in your wall. If things dont work plug off the wall, open up behind, you will see a thin pipe coming down from the pressure switch to the drain area. Disconnect this pipe carefully from the top and blow into it, it should be free. If blocked clear, if broken or damaged change. Refit carefully.

Pl rate me helped.......
