You need to push in on the coupler and right at the connection it has a collar to pull out on to release the connector

Can you suggest an alternative soft flexible hose for a Karcher power pressure washer 100bar


You need to ensure the Hose can handle the PRESSURE your machine is putting out. The Flexibility is a direct correlation to the requirement of the hose's ability to handle the pressure. Your 100 Bar is equal to 1460 psi. Depending on where you live, there are places that have Hose and Couplers and can make a Hose to your Specifications with the above information.

I was unable to get the water through the hose, but it did run freely from the washer with the hose off. I took the wand/handle apart to clean it and I am now unable to generate enough strength to compress...


Hi Bill,

Yea, I've had that same problem. What I have done is to put the spring in a vise to compress it, then tying the coils together with some thin wire, putting it on the "tool", then snipping the wires.

I hope this helps. If it does, I'd appreciate your vote. Thanks,

Water pressure not that good , sometimes have to shut washer off then crank back on and sometimes its OK


It sounds like you are getting air into your pressure hose. Try just turning your faucet on and squeezing your wand handle for a few minutes before you crank your pressure washer up. This should bleed the air from your hose.

Getting ready to move, is it hard to unhook


Hi from retired Englishman in SW France,

If your posting is complete (?) the answer is 'no'; it is not hard to unhook. Taps turned off and unscrew hoses and put them in the drum so they are not lost. Unhook (probably) the drain hose and attach as best as you can to the rear- with tie-wraps or something similar. Disconnect plug from electricity supply and do the same with the plug and cable. Those are the easy bits.
Now- ideally when moving a washer the transit bolts should be in place to stop the drum and suspension from thrashing about and becoming damaged. If the original transit bolts cannot be found, a get-around method is to remove the back and pack the interior around the drum with blocks of sponge and/or blankets or equivalent, paying particular attention to NOT disturbing or damaging any plugs, cables or hoses in the process! Careful handling and transportation should be requested ;-0)
I hope my rantings were what was asked for!
Good luck, John C

My pressure washer will not pump the soap, when you take the pipe loose from the handle it pumps out when you hook it back to the handle it quites pumping


Most pressure washers introduce soap into stream of water by the siphon method. In order for the system to siphon the pressure tip must be changed to one with large opening. Once the large tip is install, the fast moving low pressure water thru the hose and wand will draw-in soap. With the pressure tip installed soap will not be drawn-in. To spray soap and water under pressure use a large container (larger the better like clean 30 gallon trashcan) and fill with clean water and measure of liquid detergent. Use short water hose from with-in container and connect to pressure washer as normal. Keep checking water level so that washer will not run dry. Most pressue washers will **** water in quickly from container, however you can pre-fill the water hose with water to speed things up. Trailer mounted pressure washers use a very large container for water. You can estimate how log the pressure washer will take to use the water by checking the gallons per minute rating of your machine. Good luck

The F/H is Beeping at me


Try taking the hoses off the machine . Turn on the water with hoses in a sink or bucket and see if you have Good water pressure on both sides. Also I need to know if you have flood safe hoses and which screens did u clean the ones in the hoses or the ones in the water valve.

Maytag neptune front load washing machine will not fully discharge water after the rinse cycle...HELP???


Check the drain hose and clear it from any debris that might be blocking the water from draining out completely. If the drain hose is clear of debris, check and clean the pump. Disconnect the machine from the power outlet before servicing for safety purposes.

Remove the rear access panel to access the pump and disconnect the wiring harness from the terminals of the drain pump and the pressure switch.

Loosen the clamps holding the drain hose and the tub hose to the pump assembly. It is a good idea to spread a towel under the pump before loosening the clamps.

Remove the hoses and rotate the pump assembly counterclockwise to release the pump assembly support legs from the keyed slot in the base of the washer. Remove the pump assembly from the washer.

Clear the pump impeller from any debris that might be causing it to work improperly. Clean the tub and the drain hose.

Reassemble the pump, the hoses, and reconnect the wires to the terminals of the pressure switch and the drain pump. Reinstall the rear access panel and run the machine.

Replace the pump (part #25001052) if water still do not drain out completely.

Remove the plastic bag covering the pressure switch. Press in the locking tabs on the back of the pressure switch and pivot the pressure switch off the pump bracket.

Grasp the pressure switch and lift the nipple of the pressure switch from the pump cap.

Install the pressure switch into the new pump assembly in reverse of the steps above.

STARTS AND RUNS FINE BUT WHEN I START WASHING IT QUITS SPRAYING AND THEN BUILDS PRESSURE AND KILLS ENGINE


The reason it stops spraying might be a clogged gun, hose or nozzle-tip.
The reason for pressure buildup killing the engine might be a stuck unloader valve in the pump.

While you are checking each component of the "output" side, spray some penetrating lube into the "input" side of the pump (where the garden hose connects) and let it be working on the unloader valve.

Fix the spraying problem first:
Start at the nozzle and verify that it is open by using low-pressure air. Clean or replace as needed. Next check the hose (with nozzle and gun unhooked) and finally the gun/trigger mechanism.
All must be clear and open to perform correctly.

Next, pour a few ounces of power steering fluid (or similarly LIGHT oil) into the garden hose, attach it to the pump and turn on the water supply.

Leave the "output" hose, gun, etc. UNHOOKED and point the output port of the pump (where the high-pressure hose connects) towards a vacant, safe area.
Startup the engine and allow the oil in the garden hose to work its way thru. (About 1 -3 minutes of run-time.) Shut it down and attach the high-pressure hose.
Hope this solves the problem!
