Look for a plastic tube that leads to the switch most likely near the main control board (behind control panel)...possible the tube lands on ta board-mounted switch. the tube, at the switch end, should never have water in it. it is merely testing for air pressure which is directly proportional to the water level because of the opposite end of tube.

Water continual running piease help


The Water Inlet Valve on your washing machine is used to fill the tub with cold, warm or hot water for the wash and rinse cycles. The valve is operated by electric solenoids that are controlled by the timer or electronic control board and the water level control/water level selector switch or pressure switch. If your washer continues to fill during a cycle, the water inlet valve could be at fault. To verify that the valve is at fault, unplug the washer when the symptom occurs. If the washer continues to fill, then the water inlet valve is defective. If the washer stops filling, then the problem is related to the electrical circuit that controls the valve. The water level switch is a pressure activated switch that is used to determine the correct water level in the tub. This part is normally located behind the control panel and will have a hose or air dome tube that connects it to the tub. On washers that use an electronic control, this switch may be located at the sump area below the tub. As the water fills in the tub it will compress the air in the tube and push against a diaphragm inside the switch. The switch will control the water inlet valve and turn the valve off at the correct water level. If the tube has a leak or is plugged, not enough pressure may be created to activate the switch and the washer may overfill. If the switch is defective it may also cause the machine to overfill.
To determine if the switch is bad, you should first eliminate the air dome hose as a problem. Look for signs of cracks or worn areas on the hose. Remove the hose and submerge in water. Seal one end and blow air into the other end and look for bubbles. Check for an obstruction in the hose as well. If the air dome hose appears to be ok, then the water level pressure switch may be defective. Inspect the switch for signs of a mechanical defect or debris plugging the hole in the inlet nipple. To test the switch contacts for continuity with a multi-meter, you will need to apply the proper amount of air pressure to the air dome tube and then look for the switch to go open circuit at that level. The easiest way to do this is to start the washer and allow it to fill to the normal level and then remove the power cord. Locate the pressure switch and remove the wires from the correct terminals and then perform the continuity test. There should be infinite resistance or an "open circuit" when the water level is correct. If not, then the switch is defectiv

I have a hotpoint model # WLW3400S that the water fills and won't shut off when full, just keeps running in overflow.(washer)


You have a malfunctioning Pressure switch. This are usually freely available at appliance spare depots. The Pressure switch detects when the water level is at the correct place, and informs the Timer/Module to continue.

Hope this helps.

Washer will fill but it does not stop


Your water level switch is stuck.
Probably due to soap scum in the air dome line.
Remove the control console screws to access the water level switch.
Remove the small plastic hose from the water level switch and blow through it to dislodge the blockage.
If it is difficult to blow through,remove the front panel and take the hose off at the air dome on the side of the tub.
Push a small wire into the air dome to clear the clog.
Replace the hose on both ends.
Set the timer for SPIN and run a spin cycle.
Then retry the water level fill.
If it does not fill correctly,replace the water level switch.

Maytag pav2300 wont stop filling up. New timer


After the water fill, Switch off the mains, allow little water bleed through the hose that goes to the level switch. As the water flows try fixing into the level switch block.

Clean the water drips to dry and switch on the m/c. It should be alright since you say that the switch is OK when air is blowed!

Kenmore 80 series overflow


The water level switch senses the water level in the wash tub. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom . The tube is filled with air. As water enters the tub it also enters the tube. As water climbs inside the tube, it pushes on the air trapped inside and increases the air pressure. When the air pressure reaches a certain level, it triggers the switch. Inspect the air tube for kinks, breaks or damage. The tube should also be free of water. The tubing should be securely connected to the bottom of the outer tub and to the bottom of the water level switch. If the Tube is full of any water, remove it from the switch and replace it with a new one. Make sure that the new is correctly fitted to the switch.

The switch routes current from the timer control to the temperature switch and the water inlet valve when the tub needs to be filled. Once full, the pressure switch cuts the current and reroutes it to the motor on the timer control to continue the cycle. If the tube replacement dose not improve the fill performance, and it continues to overfill, replace the timer.

Filling/ Timer problem


There are a couple of things that can cause of the water to continue to fill. A defective water inlet valve that fails to shut off can cause the problem, but you were able to get the water to stop when you moved the timer selector knob. If the water inlet was leaking by, it would continue to run no matter what position the timer was in.

The next item would be a pressure switch malfunction. You were correct to assume this as a possible problem. The switch is located in the operator console behind the load level selector knob. Just remove the back panel of the console to access. Verify that the clear plastic air hose is still connected to the switch. The air hose is what detects the changing tub pressure from the air dome and shuts off the water at the appropriate level. If this air hose comes loose, the pressure switch never detects the change in tub pressure and the water continues to run. Sometimes to the point of overflowing. Over time the hose can stretch and become loose. The vibration of the washer eventually will cause the hose to fall off. If this is the case, re-attach the hose and place a small zip tie around it at the point where it connects to the pressure switch. Make the zip tie snug, but not excessively tight. This will keep enough resistance on the hose to keep it from sliding off again.

If the air hose is correctly installed, inspect the entire length of it to make sure there are no rips or tears. The hose cannot have any holes in it, or the air pressure leaks out. In addition, double check the electrical connections ot the switch by checking the contacts to ensure they are clean. If none of these preliminary steps correct the problem, you may have a defective switch that requires replacment. Hopefully you won't require any additional parts to fix your problem.

If you have any questions, please let me know. I hope you find this information helpful.

NOTE: When working inside the console, please UNPLUG the washer for your own safety.

GE SpaceMaker washing machine does not stop filling.


try replacing your water selenoid coming in. remember it isnt a mechanical timer it is a computerized timer, so if the selenoid isnt the problem, it might be the computerized timer. computers are very finicky, pain in the a- -!

GE wcxr1070a washing machine. fills with water


Check the water level switch and the plastic tubing to the switch.
Sometimes soap scum stops up the plastic hose and the water level switch does not close to send power to the timer.
If the plastic hose is good and the water level fills and stops replace the water level switch.

Washing machine fills in the water but does not start the wash cycle


The fact that it does not fill completely can be related to a problem with the water-level switch, that regulates the water level.

See from Repairclinic:
"This switch is usually a diaphragm device with a small, clear tube attached between the switch and the bottom of the washer's outer tub. As the water level in the tub increases, the pressure on the air in the tube increases. When the pressure reaches a certain level, it activates the switch, shuts off the water, and signals the timer to begin the agitate cycle. If the switch is defective, it may prematurely signal the water to shut off. If so, you probably need to replace the water-level switch."

However, when it is only the switch the mashine usually completes the cycle, but with less water than normal.

A possibilty is that either the timer is faulty or there is a problem with the water supply.

Check that water is coming from water supply with regular pressure, and that hoses back there are not obstructed.

More likely you will have to replace the timer.

See again from Repairclinic:
"When the cycle doesn't advance, it's probably the timer or a cold-water supply problem:

  • It's the timer, if your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer.


  • It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water. See There's no cold water."

  • You can find parts at the following websites, you need to input your model number. If the part is not listed contact them.

    Dishwasher fault


    If you have tried to run any cycle and still end up with this problem, then most likely a failed timer unit. The next step is for the water switch to enact the next step which is to start the timer.
