You Can Fix an Overflowing Dishwasher

A dishwasher can surely save you lot’s of time in the kitchen, but if it’s constantly overflowing, it can make lot’s more work for you to do. And, it can also damage your floor covering and if left un-repaired, it will eventually cause your flooring structure to rot.

There are several things that can cause a dishwasher to fill up with too much water and overflow onto the floor. The most common cause is the float switch, they can sometimes just suddenly start sticking. Another problem could be the electrical that starts and stops the water running into the dishwasher.

Since the float switch is the most common culprit, check it before checking the switch. The float switch is generally a cylinder shaped plastic piece that is usually on one side of the front of the dishwasher, it could also be toward the middle near where the sprayer is.

There may or may not be a protective cap over the float switch on the model of dishwasher that you have. If there is remove the screws and take the cover off so that you can get to the float switch. The switch should easily move up and down without any resistance. If it sticks, check to see if there is any debris like food particles or soap accumulated on the switch.

If the switch isn’t moving freely take it off, the float switch should just easily slide off of the shaft. Use a bottle brush to scrub the inside of the switch to remove anything that you can see. Then clean the outside of the switch with a brush.

Slide the float switch back onto the shaft and check it to see if it moves up and down more freely. Test the dishwasher to see if it still overflows by doing a load of dishes. If it does, then you probably need to just replace the float switch.

Before working with anything electrical or anything that has running water, make sure that you turn both off at the source. If you can’t get to the plug for your dishwasher to unplug it from the outlet, go to the breaker box and turn the breaker off. Try to start the washer to make sure that there’s no power running to it before attempting any repairs.

If you do need to replace the float switch, you’ll need to remove the panel on the front bottom of the dishwasher. Some panels just snap on to hooks and some are attached with screws. Once you get the panel off, find the float switch.

You’ll need to remove the wires that are attached to switch. Make sure to wrap a piece of masking tape around each wire and mark it so you’ll know the correct place to re-attach the wire. You can easily remove the wires with a pair of needle nosed pliers.

Depending on the type of screws that your model has, you’ll either need a socket and nut driver, or just an ordinary screwdriver to remove the old switch. If you’ve not already purchased a new float switch, take the old one with you to compare and make sure that you get the correct one.

To install the new switch, you just follow the same steps in reverse order. Once you’ve gotten the new switch in place and re-attached the wiring, put the service panel back on the front of the dishwasher. Plug it back in or turn the breaker back on and run the washer to make sure it’s not still overflowing.
