How To Fix An Overflowing Washing Machine – Washer Water Overflow Repair

(Last Updated On: December 22, 2013)

You just put your load of clothing in your washer, turned your back, and now it has overflowed all over the floor. There are many reasons for this. This will be a DIY fix guide for all TOP LOAD WASHING MACHINES. Front loaders work slightly different. Many older model washing machines that are a few years old may have this common issue. This is attributed to the wear and tear of everyday use that can vibrate parts loose and wear out parts over time.

The absolute FIRST thing you need to do is check the pressure switch (water level switch). The pressure switch is what senses the water level using air pressure and tells your washer to stop filling with water. The pressure switch has a tube attached to it. This tube can vibrate off of the pressure switch and therefore your machine does not know when to shut off the water. Most of the time, the pressure switch has either become clogged or the tube connected to it has vibrated off. If this tube becomes disconnected your washing machine has no way of knowing when to turn the water off. Usually you will find that the hose clamp or spring loaded screw clamp has become loose and the hose is no longer attached to the pressure switch. So, this is what you are going to check first.

You will need to clean up the mess the washer has made first. Then unplug your washer and remove the top front control panel to visually inspect the pressure switch and tube. Depending on the manufacturer of your washing machine, the removal procedure will be slightly different. We are talking about the metal panel where all of the controls are located (see picture below). Usually there will be a few screws holding the control panel in place. So once you figure out how to get that removed, you need to grab a bright flashlight and find the pressure switch on your washer. NOTE: Some washing machines have the pressure switch located at the bottom of the drum. If you remove the front control panel and the pressure switch is not there, then you need to remove the lower front panel to gain access. See your user manual or do a Google search for your washing machine.

On most top loading washing machines, the pressure switch is located behind the control panel.

Once you have the panel removed, locate the pressure switch or water level control valve and see if the tube is still attached. If not, reattach it so it does not vibrate off again (zip tie and small hose clamp). Once reattached, put panel back on and test machine. If the tube is still connected to the pressure switch, then most likely the tube is clogged or the pressure switch is either stuck, clogged, or has failed. If the tube is not clogged up, then you should remove the pressure switch and clean it out to remove the clog. Remember, the air pressure from the washer goes through the tube and presses against the pressure switch. So you can push or blow into the pressure switch and see if it is working. If there was a clog or it was stuck and you fixed it, reinstall it and test the washer. If the pressure switch is burned or cracked we recommend to replace it. Many online appliance parts websites have your type of pressure switch / water level switch that include free 2 day shipping.

  1. I have a top load washer that overfills. The pressure switch functions normally and the pressure tube is clear. When the tub is filling, I can see water going into the pressure chamber but only fills slightly; leaving no water to run up the water tube. When I unplug the pressure tube from the pressure chamber, I notice the water begins to rise in the chamber. What is the problem?

  2. I have a GE WHRE5260E1WW that had overfilled and began to spill out onto the floor. I’ve checked the water level sensor behind the panel and in the front panel where the opposing end connects. Both are secure and there doesn’t appear to be any blockages. What else can I look for?

      If the water level pressure switch is securely connected electrically, then check the water level pressure switch with a meter to be sure it is working and is getting power.
      If so, then check the water inlet valve as it may not be shutting off in time.
      Also if there is a small clear tube attached to the water pressure switch, be sure it is clean and securely attached.
      At times the small clear tube will clog up and prevent the pressure switch from working properly.

  3. We have replaced the water level switch and the washer is still overfilling with water. It worked half way through the wash then the cycle stopped. When we restarted it the washer just kept filling and wouldnt stop til we stopped it told it to drain and spin. What else could be the problem?

  4. We have an Asko 20005 Excellence washing machine…20 years old. Its works fine but can overflow. The pressure switch has been checked and seems to work. We have unusually high water pressure (eg. I don’t need to buy a pressure cleaner for cleaning cars!). I turned down the water supply tap to 50% and all overflows stopped, regardless of which type of wash we did. Could it be that our domestic water supply is just too high to have the machine run on full pressure?

      John Boyd,
      Try shutting off power to the washer. If the washer still overflows even when it is not getting power, this indicates that the water inlet valve is defective. If the water inlet valve is defective, replace it.
      If that is not the issue, you may need to check to be sure the water pressure switch is in working condition.

  5. This question is for my top-loading LG WT4870 CW machine. It’s filling with water to the brim no matter how large or small my laundry load is. It’s not overflowing all over the floor, but water is leaking out of the drum when it agitates because it’s overfilling. I believe it may be the pressure switch. Does anyone have any tips on checking that valve for clogging and/or replacing the part if needed?
    I believe the part is not located in the top panel of the machine, but rather in the back, beside the drum. Any advice would be great. Thanks all and happy new year!

      Yes the washer water pressure switch is located usually (on top load washers) behind the front panel and to the right. If it is clogged or has hard water blocking it, the washer may overfill or under-fill… Remove power to machine and remove front panel to check to be sure it is not clogged. Take it out of the machine and clean it completely. Clean out the tube also. Reinstall in the washer and run a test wash. This should fix your issue.

  6. Figured out we needed to cut the end of the hose off to make it a snugger fit but thank you for replying.

  7. My washer was filling up but then stopping. First guess was lid switch so I tested it with a jumper wire and it didn’t fix the problem. After a couple hours it just started working again. It happened again a couple months later when once again cleaning pillows. I figured the load was big and causing water to splash up onto wires/circuit board so I unplugged it and waited a few hours and when I plugged it back in it was fine. Figured it needed to dry out. Happened again today but with just a regular load (all be it full) of clothes. Unplugged it and waited but nothing. Tried messing with the lid switch again and again it didn’t work. When I removed some clothes the water came on to fill the tub back up. So I figured the overload sensor got triggered but wouldn’t reset. In an attempt to figure out how to fix it I removed the pressure valve tube and I heard the pressure being released. I replaced the tube but now the water wont stop running unless I turn off the machine. Any help? Old Kenmore 80 series (inside top of washer looks very similar to what’s in video). Thank you.

      Most likely water pressure switch hose is not secure. Probably fell off or gunk in it or switch itself may be gunked up. Check once again and be sure it is secure.

  8. Hi there! i have a Pitsos Vario Inox 4600 front load washing machine and i need to know how to wire the pressure switch?
    Do you have a diagram or service manual or any photos or info – I have scoured the internet for days now and i cannot find any information.

    This is what i have:
    Low pressure control (9 contacts-3 levels 62/25, 77/39, 90/55) for washing machine PITSOS/BALAY Low pressure control (9 contacts-3 levels 62/25, 77/39, 90/55) for washing machine PITSOS/BALAY
    Code: 33902
    Low pressure control (9 contacts-3 levels 62/25, 77/39, 90/55) for washing machine PITSOS/BALAY

    and it fits the following machines also:

    (E-Nr. : WFB2000/01 , E-Nr. : WFB200000/07 , E-Nr. : WFB2010GR/11 , E-Nr. : WFB2010GR/03 )

    (E-Nr. : WFA2070/00 , E-Nr. : 4600/07 model:(MOD:) : 4600 , E-Nr. : 4900/07 model:(MOD:) : 4900 , E-Nr. : WFBPI03GR/16 , E-Nr. : LI4600/07 , E-Nr. : 4600/08 , E-Nr. : 4600/02 , E-Nr. : LI4600/17 , E-Nr. : WFBPI02GR/22 , E-Nr. : LI4600/01 )

    (E-Nr. : WM21000/02, WM21000/01, WM21000SK/01, WM21000SK/02, WM21000CH/01 )

    Basically when i removed the switch to replace it, there is no plug to simply plug the wire assembly back into it – they are all separate wires – i had taped them so that i could re insert them however, the tape didn’t hold and when i came back to it the wires all separated…. on my machine there are no wiring plugs they are all separate wires with clips to insert into each prong/terminal…. hence my dilemma, unsure of how to wire it back together…

    Please help! :) thank you in advance!

      Hi Emanoyhl,
      If you do not have the manual and have zero reference to rewire the pressure switch, are there any numbers or letters next to each wire connector on the switch? Are the wires from the washer to the pressure switch color coded or numbered?

      1. hi there!

        yes, the pressure switch under each terminal has numbers, and the wires are color coded….

        the pressure switch numbers are as follows:
        31, 36, 24, 11, 13, 32, 21, 22, 12, 34 (there are 10 terminals total, but only 9 wires total) – i do know that the blue wire goes to terminal 24 (because that was the only one “alone”)

        the wire colors are: (single)black, (double)green, (single)blue, (single)brown, (1)brown/(1)black, (single)red, (1)brown/(1)black, (1)red/(1)yellow, and (1)red/(1)yellow
        when i say “brown/black and red/yellow” they are actually 2 wires together, solid red and solid yellow, and solid brown with solid black clamped per terminal end…. the red/yellow for example, the yellow comes from the water inlet valve, and is terminal clamped with a red wire that goes to another terminal clamp with another yellow wire that comes from the timer box (so that red wire for the 2 sets of red/yellow is actually like a bridge between the yellow wires) – the green wire also comes from the water inlet valve and is also doubled at the terminal clamp which then goes to the timer box – all the wires are 2 wires per 1 terminal clamp except for the red, brown, blue, and black – the blue and brown wires are from the power supply that goes to power switch, then from there to timer, then from there to this pressure switch – the 2 pairs or brown/black wires come from the timer box, but the single black wire comes from one of the brown/black set….

        i hope that made sense? :)

        thanks again in advance! i could supply photos if necessary!!

        We would suggest calling the manufacturer of your washer and asking to speak to technical support. It may be possible for them to email you a wiring schematic for the pressure switch you need to reinstall. We would love to assist but we are unable to find any relevant wiring guides or diagrams that will help us help you. Try calling the toll free number for support.
