7 Reasons Your Dishwasher is Overflowing
You’ve got your dishwasher nice and loaded; started it, and you’re ready to turn it in for the night. But wait, is that water coming out of the unit? Looks like you’ve got an overflowing dishwasher.
There are loads of reasons why the dishwasher can overflow and they can all lead to water damage on the floors, nearby cabinetry, and walls. Let’s explore the ways a dishwasher can overflow and what steps you should take if there’s water damage.
Why Is My Dishwasher Overflowing?
1. Worn Out Dishwasher Door Gasket
The dishwasher gasket is a rubber seal around the door that keeps water and soap from escaping. When it’s damaged or worn out, it allows dishwater to seep out and onto your floors or cabinets. Replace the damaged or worn-out gasket.
2. Too Many Soapsuds
The more soap you use, the more clean your dishes will be, right? Well, maybe at the expense of an overflowing dishwasher. Too much dishwasher detergent or dish soap can create a massive buildup of soapsuds. Stick to the recommended amount to avoid this.
3. A Broken Water Inlet Valve
A broken inlet valve won’t properly fill your dishwasher, sometimes resulting in an overflow. One of the other ways you can tell you have a broken water inlet valve is water pooling in your dishwasher despite not having used it. Call an appliance repair specialist to take care of this before it leads to water damage.
4. Leaky Dishwasher Tub
Load after a load of detergent and minerals from tap water can eventually cause a hole to form in the dishwasher tub. Although you can fix the problem, you may want to consider replacing the unit entirely. If the problem is severe enough, it’s probably better to replace your dishwasher to avoid other costs and issues due to water damage.
5. A Defective Float Assembly or Switch
A defective or stuck float switch won’t signal to your dishwasher to shut off water flow. This can easily lead to the dishwasher overflowing with water and more water flowing in freely. You’ll need to replace or fix the defective float switch to avoid an overflow.
6. Clogged Dishwasher
Do you notice standing water in your dishwasher after it’s finished? Then it likely has a clog. Check the drain at the back of the unit for clogged debris and the drain hose for kinks.
7. Improper Alignment
Sometimes, installation mistakes can lead to dishwasher overflows. A misaligned dishwasher has a greater chance of water gathering underneath it. To check if your unit is properly aligned, place a level on it. If it’s not level, place shims underneath and recheck until it is.

Dishwasher Overflowing FAQs
Why is my dishwasher overflowing when it is not running?
If your dishwasher is filling with water when it is not running, the water inlet valve may not be shutting off properly. A faulty valve can allow water to continue entering the dishwasher even when no cycle is active. Turn off the dishwasher’s water supply if water continues to enter the unit, and have the appliance inspected or repaired to prevent an overflow and potential water damage.
What should I do if my dishwasher overflows?
Stop the dishwasher and, if it is safe to do so, shut off its water supply. Clean up standing water promptly to prevent it from spreading into flooring, cabinets, or walls. Avoid using the dishwasher again until the cause of the overflow has been identified and repaired. If water has reached surrounding building materials or caused significant standing water, professional water damage assessment and cleanup may be necessary.
Why is my dishwasher overflowing into the sink?
If water from your dishwasher is backing up into the sink, the problem may be somewhere in the dishwasher’s drain path or connected sink plumbing. A clogged drain hose, garbage disposal connection, air gap, or sink drain can prevent wastewater from leaving the dishwasher properly. Check the dishwasher filter and drain path for obvious debris, and if the problem persists, have the drain system inspected to determine where the blockage is occurring.
How do I know if a dishwasher overflow caused water damage?
Signs of water damage after a dishwasher overflow can include wet or warped flooring, swollen cabinets, damp drywall, discoloration, musty odors, or moisture that remains after the visible water has been cleaned up. Water can spread beneath flooring and into cabinets or walls where it may not be immediately visible. If a significant amount of water escaped from the dishwasher, inspecting the surrounding areas for hidden moisture can help prevent more extensive damage later.
