Can't get the quck connect valve to work

that's probably the unloader valve all it might need is a quick dissasle to see whats gumming up the works , as all I was able to find for sale for that model here was a new gun and the soap injector for about sixty bucks each , you might have to look around in the Uk for one as that's were there most popular

no water coming in--tap or hose kinked
no connection to the motor --drive coupling broken -loose
pressure regulator valve not working

release pressure by squeezing trigger then grab the brass quick connect fitting at the knurled section (at end of hose) and push it toward the pump. when properly pushed back, the hose connector will pop out.

Hi Mike
You could have one are two problems with the pressure washer.
1...pump for pressure washer worn and needs washer/seal replacement.
2...Need to adjust the pressure discharge relief valve to the needed pressure.
Please take time to rate me

The fill time is taking too long as what error code E10 pertains to. The problem is either the water supply is not turned on, the water valves are not working or the screens are blocked, the pressure switch is not tripping, or the water flow meter, is there's any, is not working. Check if water is actually coming in or not.

Water Not Coming In
The problem is with the water supply or the water valves. Make sure the water supply is open and the water valve screens are clear. If water supply is on and the screens are clear, measure the voltage across the water valve solenoid which must be around 120VAC when the water valves must turn on. If there's voltage, the problem is with the water valves, replace it. If there's none, the problem is with the timer/control or the wire harness connecting the water valves. Check the wires and if there's no problem, the timer/control is fault and needs to be replaced.

Water Coming In
The problem is with the pressure switch not tripping. Check the pressure hose attached to the pressure switch for kinks and air leaks as these can prevent pressure build-up that should trip the switch from empty to full position. Also detach the pressure hose then blow air forcefully down through to clear any possible clogs. Do the same with the pressure switch inlet to possible free welded or stuck contacts. Replace the pressure switch if there are no apparent problem with the pressure hose and its connections to both the switch and the bottom of the tub.

FH: If after 30 seconds the control does not detect water entering
machine, the valves will be turned off and the error code will be
displayed. OR If the control has turned the water valves on and after
8 minutes the flow sensor has detected 10.5 gallons of water passing
through it, but has not detected the pressure switch trip, the valves will
be turned off and the error code will flash.
Press PAUSE/CANCEL twice to clear the display.
If there is no water in the unit:
-Make sure that both valves at the water source(s) are turned
on all the way.
-Check for plugged or kinked inlet hoses or plugged screens in
the inlet valves.
-Verify inlet valve operation.
If there is water in the unit:
-Verify drain pump operation.
-Verify that the pressure switch hose is in good condition and
properly connected to tub and pressure switch.
1. Verify there is not a siphon problem.
2. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves,
pressure switch, drain pump, flow meter, and
Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power
6. Verify pressure switch operation.
7. Verify flow meter operation by blowing air through the part and
measuring the resistance.
8. Verify CCU operation by running a Diagnostic test or any cycle.

shut off the hot and cold water.disconnect the water line from the washer and stick them in the washer,turn the water back on,make sure you have someone hold the lines so when the water is on the hoses don't spray all over the place from the pressure in the lines,if no water comes out you have a bad home water valve and need to change it out,if water comes out check the valve where the water lines connect to on the back of the washer,if there are screens inside the opening on the valve pull them out and clean them or you'll have to change the valve out.you didn't send the model number so i don't know what kind of machine you have,if it's a newer washer you could have problems with the electronics or something else,also i've seen water lines with pressure valves in them,if you have this change them out to regular burst proof hoses.good luck

The automatic clothes washing machine counts on a pressured water system - like what is provided in a town / city or from a well that has a pressure system to deliver water at pressure like when you open a valve for a bath tub, sink or shower.
You need to have a plumber provide valve/faucets for both hot and cold water. The valves are sometimes called a "hose bibb" with a threaded end that the hoses connect to and then are connected to the back of the washer. When the hoses are connected and the valves are open, the automatic washer will open a solenoid valve when the time is right to allow water to flow in, then closees. Some owners keep the hose bibb valves open forever after they connect the washer, others close the valves after they are done washing all loads for the day/week.
You will also need a drain provided that connects into the house plumbing. The Whirlpool Duet provides the drain hose from the washer which drops into the pipe the plumber provides. It is important that the drain pipe allow air to move past the washers drain hose, to allow proper draining.
Hope that helps. Please post back how things come out, OK?

It sounds like an air lock. Try this: With the machine off, connect the hose to the washer and let it run for several minutes to get all of the air out of the hose, and to purge any air out of the pump. Shut off the water, and connect the high pressure hose, but not the gun. Let the water run for several minutes. stretch out the HP hose and make sure that the air is displaced. Shut off the water, connect the gun, and purge as before. Now crank it washer up. As quickly as safe to do so, open the trigger to keep water moving through the washer. It should come up on pressure very quickly. It is better during normal operation to keep water moving through the system. When I am through for a while, I shut down my washer, but leave the trigger depressed to allow the pump to stay full of water, and cool. This prevents further problems when I restart it.
Hope this was useful.

I have foud a solution 4E error for my Samsung WD7101CKW. Water that comes inside washer is splitted in splitter with valves. One of these valves has a red label on it - this is a valve with restrictor of flow inside. This restrictor is used to limit flow speed mainly for testing purposes of pressure/water level sensor. Because of that restrictor (red cap with two holes of 0,5 mm diameter) blocked flow too much, after some time washer controller thinks that water has too low pressure.
Unplug washer, disassemble hoses from valves, disassemble valves from the washer (screwdriver needed), drill both holes in red restrictor to 1 mm (use 1 mm drill or just big needle). Assemble in reverse. Will work :)
