What is the machine model number so I don't waste your time or mine. If it's a FAV6800A or FAV9800A I can help you.

If you pull the power to the machine while the machine is filling with water will the water stop flowing?

marka19 we are in a model specific forum. I would need to know the model number and s/n of the posters machine. I watched the vid and I know the FAV6800A/FAV9800A machine very ell and the vid would not get the forum member even close to solving the over fill issue for a FAV6800A or FAV9800A machine.

A true DIY Washer repair forum will ask for Model Number and S/N before you post any comments for support.

    “”yes the water stops model#FAV6800AWW ser#1054171633 please help “” OK that tells us the Water Inlet Valve is not stuck open and closes preventing water flow with no 120VAC to those solenoids. A very basic 101 first step in troubleshooting an Overfill condition.

    Rich I’m an owner like you not a repair person. We are going to get into some DIY stuff to fault isolate the issue. I’m sure it is the pressure switch as the other forum member mentioned but these folks need to understand the machine and not just throw out general statements. Unless you enjoy Easter Egg hunts…… I’m too old for that stuff and I’m sure you are also.

    Your FAV6800A is a Series 10 machine that’s the 1st two digits of your S/N.

    Here is the FAV6800A/FAV9800A Service Manual for reference. Sears Parts Direct for reference.

    If you pressure switch is defective your Series 10 machine uses a 3 level pressure switch for water fill level sensing. We are going to check for pressure switch transitions in Service Mode as we add water to the wash basket. No matter who you order the pressure switch from make sure they know the Pressure Switch needed is for a Series 10 FAV6800A machine. The two P/N’s are 25001053 which I believe is for the 3 level sensing pressure switch but check and 25001204 for Series 12 and above again check with the parts supplier against your S/N.

    This forum is message length restrictive so I may have to add additional comments.

    OK before we spend any money for parts let’s confirm the fail point.

    Go in to Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”

    Go to page 16 of the Service Manual lower right hand corner. Follow the steps to enter into Board Functional Test Input Control

    You will bucket fill the wash basket with cold water and check if the Pressure Switch transitions go from 0 to _1 for Low fill, 0 to -1 for mid fill and I can’t type do the 0 to _-1 upper fill you get the point.

    My FAV6800A series 10 machine transitions to low _1 with very little water in the wash basket. I transition to -1 for about 3.5 inches of water in the wash basket and 7 inches of water or around the horizontal ring in the wash basket for High fill level trip point. Do you see any transistion from 0 to _1, -1, or the upper -1 for the bucket fills?

    If it is not I would check to make sure the connector is seated on the pressure switch which sits on top of the Drain Pump.

    It’s in a very difficult location to get too. In this pic the pressure switch is shown sitting on top of the drain pump. To get it out you would have to remove the drain pump.

    In this pic I show the Pressure Switch sitting on top of the Drain Pump with the Outer Tub removed for a Outer Bearing replacement job.

    See if this helps.

    Rich follow all safety instructions in the Service Manual and power down/disconnect the washer 120VAC power cord before going into the machine.

    I go by D*ick but this forum auto detects that as a badddddddddddd word.. So let me know if I can help………Rich

    Forgot to add you can empty the water in the Wash Basket/Outer Tub by going into Service Mode and turning on the drain pump or select a Spin Only cycle for a couple of minutes then hit the Off buton.

The problem is the pressure switch has failed or the hose is plugged up, has a hole in it. These are usually inexpensive and are very easy to replace. There is a video at this will walk you thru the inspection and replacement of this part. You can also enter your model # for diagrams and illustrations of your specific model. All parts come with installation instructions. Not all models are available.

SOURCE: Washing Machine won't stop filling up

Try resetting your water level control. If that doesn't help then set the water level control to the lowest setting and observe if level exceeds that setting. If so, you may possibly have a faulty water level control, or an obstruction in the air dome or water level control hose. This can be a tricky 1 to diagnose for a novice.

SOURCE: washer won't stop filling with water

In yor machine control panel you have A part called a pressure switch or water level switch. that controls the water level and tells the timer to start aggitating .If the part is bad the machine will over fill and keep running the water!!

SOURCE: water keeps going and overflows

Hi and welcome to FixYa. I am Kelly

You will have to open the top panel for steps below

Water level control is handled by the water level pressure switch inside the top panel. It is about 3.25 inches in diameter, has 3 wires connected to it and a hose that looks like a small vacuum line.

Check that vacuum looking line for any holes, kinks or disconnects.

You will need about 3 feet of the same knid of line available from any autoparts store for this test.

Remove the machine side hose and connect the 3 ft hose you just obtained. DO NOT drop the machine hose into the machine.

Place the timer on the wash cycle and start the cycle
Result = fill

Force air into the hose orally until you hear a click.
Result = fill stop agitation begin

If it does not pass this test then the pressure switch is bad.

If water never stops flowing the water inlet valve has debris internally and will probably have to be replaced.

Don't forget to reconnect the machine side hose to the pressure switch.

Thanks for using FixYa!


Then remove the vacuum

Electrolux washer MEX731CFS0 overflows

Possible fault with the inlet valve section. It is possible that the inlet valve is open, clogged or is not working due to a faulty coil. also if there is no voltage from the program controller unit it will not be active. so check this voltage to the inlet valve to confirm.

Water level control switch not working. even i set water level to very low it just keeps filling and has overflowed. i am guessing that the switch needs to be replaced.


It depending on exactly what your seeing that will determine the problem.

Does your washer start agitating and keep filling?? if yes it does start agitating and the water continuies to fill try disconnectiing the power and if it keeps filling what would be wrong is that the water inlet valve is sticking open and it would need to replaced

If the washer continues to fill and does not start agaitating would be a defective water level switch as you suspect it may be.If ya disconnect the power and it STOPS filling replace the water level(pressure) switch.

The washer fills and begins agitation, but continues filling and overflows the tub after agitation starts. Does not fill when unplugged.Both hot and cold fills are affected.

There is a pressure switch which stops the fill cycle, It is attached to the drum by a clear
tube. as the water comes up in the tank, pressure builds inside a cup that is molded on
the side of the tank, if the inlet to the pressure switch becomes plugged with lint, it
will cause this symptom. The switch is located behind the control panel. Unplug washer
and remove two philips head screws at bottom corners of the panel. It will usually hinge back. Inside is the float switch. Try removing the tube and blow into it, this will
clear the end, then see if it corrects the problem, if not then the switch has failed.
Hope this is of help to you.

My wahser just stopped working it filled with water and then started agitating and then all the sudden stopped please help

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

    LSE7806A stack: the wash fills to the water level/load size selected. it starts to agitate then stops and begins to fill with water again which causes overflow, help please

    Your fill sensor is leaking and allowing air pressure from the clear tube to seep out. First make sure your clear tube from the tub to the water level valve is firmly connected. If it is then you may need to get a new water level adjuster switch.

    Agitator starts at begining of cycle before washer is full

    Please be carful as running the agitator without enough water will overheat and kick out the motor, however it should be ok when it resets itself.
    Yes, the machine should stop agitating when you lift the lid so this too is part of the problem.
    After looking at the print I can only suggest that the cam contacts in the timer ( contacts 12 and 14) that start the motor are burned and stuck together.

    Ultimate Care II - water doesn't stop at the fill line, keeps filling to overflow and will not agitate

    If the washer overfills, it may be something as simple as a detached or broken air hose on the pressure switch. The following link explains:

    The pressure switch on top loaders is located behind the load level selector knob on the operator console. The pressure switch on front loaders will be located inside the cabinet, usually mounted along the back interior wall. In the case of certain Maytag front loaders, the pressure switch is actually located under the tub. The principles of operation on all of them is the same, though. They all have an electrical connection and an air hose that detects the pressure from the tub as the water level rises.

    If the pressure switch is not able to detect the water level properly, it will not shut off and the washer will never begin the wash cycle. Instead, you get a tub overflowing on your laundry room floor.

    Read through the link provided and let me know if you have any questions. I hope this helps you.

    NOTE: Another source of an overflow could be the water inlet valve. This is usually a slow fill fill that you find when the washer is sitting idle over night. A quick test to determine the source of the problem is to unplug the washer. If the water stops - pressure switch. If the water continues to fill - water inlet valve.

    If you have questions, please let me know. I hope this helps you.

    Washer fills continuously until it has overflown

    I found this answer on Hope it helps...

    Water-level switch A defect--or an obstruction--in the water-level switch may mean that it can't tell the water to shut off. So the machine overflows. This switch senses the water level in the clothes tub. It's 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. You can either clear any obstruction in the tube or replace the water-level switch.
