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.
