Why Does My Dishwasher Keep Leaking?

A dishwasher leaking can be frustrating, but the good news is that it’s often caused by issues you can fix yourself. Here are some of the most common reasons for leaks and what you can do about them:

Worn-Out Door Gasket or Seal

The door gasket (or seal) is what keeps water inside the dishwasher during a cycle. Over time, it can get dirty, cracked, or worn out, which means it won’t seal properly, and water can escape from the bottom.

Take a look at the gasket. If your dishwasher is cracked or damaged, it's best to call a professional technician for a dishwasher repair service, and consider replacing any faulty parts to restore proper function. Regular cleaning can also help prevent issues.

Trouble with the Water Pump System

Your dishwasher’s pump system is responsible for circulating water for washing and draining.

If dishwasher parts like the pump, hoses, or clamps are damaged or loose, water can start leaking out the bottom.

Check for cracks or loose connections and replace or tighten anything that isn’t in good shape.

Clogged Filter

The filter traps food particles to keep the drain clear, but if you don’t clean it regularly, debris can build up and block the water flow. This can lead to overflow and the bottom of the dishwasher leaking.

Make it a habit to remove and clean the filter at least once a month. This will help keep things running smoothly.

Problem with the Water Inlet Valve close-up-of-a-dishwasher-water-inlet-valve

The water inlet valve controls how much water flows into your dishwasher. If it’s broken, too much water can get in, causing leaks from the bottom. You might also notice unusual noises while the dishwasher fills.

If the valve isn’t working right, it’s best to repair or replace it to avoid more leaks.

Float or Float Switch Issues

The float and float switch are there to control water levels inside the dishwasher. If the float gets stuck or the switch isn’t working, your dishwasher might overfill, leading to a leak under the dishwasher.

Check that the float can move freely and inspect the switch for any damage. Replace any broken parts to keep water levels in check.

With a little inspection and maintenance, you can often solve these issues yourself and avoid further damage to your dishwasher!

Can a Leaking Dishwasher Be Repaired?

The short answer? Yes, you can fix a dishwasher dripping. But it all depends on what’s causing the problem. Here’s a quick rundown of potential fixes:

  • Replace the Door Seal: If water is pooling at the bottom, it could be a worn-out gasket. Replacing it is quick, easy, and affordable.
  • Fix the Pump or Valve: A leaky water pump or inlet valve might need replacing. If the dishwasher leak repair costs more than half the value of your dishwasher, it might be time to upgrade.
  • Check the Drain: A clogged or damaged drain hose can also lead to leaks. Clearing out the block or swapping the hose usually does the trick.
  • Call in a Pro: For bigger issues like a broken float switch or tub damage. It’s best to let the experts handle it. A service team can ensure everything is fixed properly.

DIY or Call the Pros?

  • DIY Dishwasher Leak Repairs: Simple fixes, like unblocking a drain or replacing a gasket, are easy enough to handle yourself.
  • When to Call for Help: For trickier problems, like pump failures or major leaks, it’s worth bringing in the professionals to get it done right and keep your dishwasher running smoothly.

Diagnose a Dishwasher Leaking from Bottom: Step-by-Step

Before you jump to conclusions, take a moment to properly figure out where the leak is coming from. Here's a step-by-step guide to help you inspect your dishwasher:

Step 1 - Turn Off the Power and Water

First things first. Unplug the dishwasher or switch off the circuit breaker to stay safe. Then, turn off the water valve under the sink. This stops the water flow and prevents any accidental flooding while you check things out.

Step 2 - Check the Door Gasket

Take a good look at the door gasket (that rubbery seal around the door). If you see any cracks, tears, or dirt, give it a quick clean with a damp cloth or replace it if it’s damaged. A good seal is key to keeping water where it belongs and to preventing the dishwasher door from leaking. For a detailed step-by-step, check out our guide on how to fix a leaking dishwasher door.

Step 3 - Look at the Water Pump and Inlet Valve

Pop off the bottom kickplate and check the pump and inlet valve. If they’re leaking or look damaged, you may need to replace them. Calling in a pro for this is usually a smart move.

Step 4 - Inspect Hoses and Connections

Check all the hoses and their connections for leaks or wear and tear. Tighten any loose fittings or swap out damaged hoses to keep things running smoothly.

Step 5 - Clear Any Blockages

Don’t forget the filter! Clean it out to remove any debris, lime deposits or blockages that could mess with proper drainage. Keeping the filter in good shape can save you a lot of trouble later on.

With these steps, you’ll have a better idea of what’s causing the leak under the dishwasher and whether it’s a simple fix or time to call in the experts.

Is a Dishwasher Leak Covered by Insurance?

Dishwasher leaking can sometimes be covered by your home insurance, but it really depends on the situation.

Here’s what you need to know:

What are the causes of a leaking dishwasher?
If it’s a sudden issue, like a burst pipe, your insurance will likely cover it. But if it’s from wear and tear over time, you’re probably out of luck.

What does your policy say?
Take a close look at your policy. Some cover accidental water damage, but there are often exclusions for things like leaks from old appliances.

Are you keeping up with maintenance?
If you’ve been neglecting regular upkeep, your claim might get denied, even if the damage was unexpected. Regular servicing can save you a lot of trouble down the line.

Pro tip:
Take some clear photos of the damage and contact your insurance company ASAP to figure out what’s covered and get the claims process rolling.

Preventative Measures to Avoid Dishwasher Leaks

An ounce of prevention is worth a pound of cure, right? Here are some easy tips to prevent your dishwasher dripping:

Keep It Clean

Take a minute each month to clean the dishwasher filter. It’s amazing how much gunk can build up! Don’t forget to wipe down the gasket, too. A clean dishwasher means fewer leaks and better performance.

Use the Right Detergent

Stick to dishwasher-specific detergents and avoid the temptation to overload on soap. Too much detergent can leave behind residue and make your dishes less sparkly.

Check for Wear and Tear

Give those hoses, seals, and clamps a quick look now and then. If you spot issues like dishwasher seal leaking or dishwasher door seal leaking, replace them ASAP to avoid leaks and keep things running smoothly.

Install It Right

Make sure your dishwasher is level and properly hooked up. A wobbly or poorly connected machine can cause leaks and other headaches down the road.

A little TLC goes a long way in making sure your dishwasher stays in tip-top shape!
