How to Fix a Dishwasher Leaking Water

The dishwasher is one of the most wonderful modern inventions. It cuts down on your time to get the kitchen clean, it does a much better job of cleaning dishes and utensils than using a dirty sponge, and it has probably kept the peace in families all across the country when someone just doesn’t feel like doing the dishes. But when it malfunctions, it can be a source of stress. Such is the case when it leaks. Why does it happen, and what can you do to fix it?

6 Reasons Why Your Dishwasher is Leaking Water

Before working on your dishwasher, remember to unplug it and to shut off power from the circuit breaker. Also, shut off the dishwasher’s water valve. It’s located under the kitchen sink.

1. Old door gasket

This is one of the most common reasons for dishwasher leaks. When this occurs, you’ll see water leaking from the sides of the dishwasher. Just as with refrigerators, the gasket around your dishwasher’s door can get worn over time and lose its ability to seal correctly. To verify whether this is the issue, open the dishwasher door and run your hand around the gasket. If you notice any cracks or missing pieces, you’ll know it’s time to replace it. Same if the door opens without giving a slight pull.

How to fix it: Order a new one from the manufacturer. Once you receive it, pull out the old gasket, and replace it with the new one.

2. Broken wash arm

This is the spinning portion on the bottom of the dishwasher. If it’s cracked, tilted, or broken, it can force water through the edges of the door. Before automatically assuming that there’s a problem with the wash arm, first make sure that no dish or utensil is blocking it from rotating.

How to fix it: Simply pull out the defective arm and replace it with a new one. Make sure you have the correct make and model of your appliance.

3. Loose tube connection

If the tube that connects to the water outlet opening is loose, water will spray continuously and cause waves on the bottom of the dishwasher to seep out.

How to fix it: Open the dishwasher and remove the bottom rack and the arm wash. If the tubes are loose, you’ll be able to see it. You can manually tighten them back together.

4. Broken water inlet valve

This is the opening where water comes out during a wash cycle. It’s located on the sidewalls of your dishwasher. Regular wear and tear can sometimes cause it to get stuck in the open position, causing your dishwasher to overflow.

How to fix it: Inlet valves cannot be fixed, so if this is the case, you’ll have to purchase a replacement. Note the make and model of your dishwasher to order the correct one.

Dishwasher Pump Leaking

5. Damaged sump seal

To figure out if this is the issue, purchase a drain pan floor mat with a spout on the front. If the problem is a broken sump seal, the pan will fill up with water, which will be diverted to the front of your dishwasher. Use the screwdriver to remove the sump’s lid.

How to fix it: Purchase a new sump seal for your particular make and model of dishwasher. Open the cabinets under the sink and disconnect the dishwasher from the water supply valve – place a small bucket or folded towel underneath. You’ll need a wrench to loosen it up. Open the dishwasher and remove the lower rack. Use a Phillips screwdriver to remove the screws that attach the dishwasher to the countertop and cabinets. Pull the dishwasher from under the cabinets. Lay a big towel on the floor, then lay the dishwasher on its back on top of the towel. Remove the screws from the bottom of the dishwasher and disassemble the pump. Follow this video tutorial to replace the broken sump seal.

Dishwasher Leaking From Motor Area

6. Cracked motor shaft seal

This seal is located underneath your dishwasher. If water is leaking from under your dishwasher and the sump seal is relatively new, the issue may be with the motor shaft seal.

How to fix it: Newer models allow you to simply replace the seal – while others require that you replace the entire motor. If your dishwasher is in the latter category, open the dishwasher, remove the bottom rack, remove the wash arm, and pull out the entire circular base that holds it up.

If your problem persists, then it may be a more complicated issue. Call a certified technician to help you identify the source of your problem.
