The experts at Maydone are happy to provide you with a step-by-step guide to help your leak and learn how to fix it!

Prepare and Get Started 

Before you start troubleshooting and fixing your leaking dishwasher, you should consider safety and what you will need to fix the issue. 

First, you must always ensure that the appliance is unplugged or disconnected from the power source. Remember that dishwashers have a dangerous mix of water and electricity, so it’s best to be extra careful.

Additionally, have some towels, a mop, and a container at hand to catch any excess water that may spill out during the repair process.

Step 1: Start At The Door 

The most common culprit behind a dishwasher leak is faulty door gaskets. Because doors have to hold off the water pressure from the inside it means they can get worn and start leaking. 

Your door gasket is the rubber seal that runs along the edge of the dishwasher door. Over time, it can wear out, become fragile, or get damaged by debris, causing water to seep out. 

How Do You Check A Door Gasket For Leaking?

1. Open the dishwasher door and carefully examine the gasket for any visible signs of damage, like cracks, tears, or wear
2. Clean the gasket with a damp cloth to remove any food particles or residue that may be preventing it from sealing properly
3. If you find any damaged areas, you may need to replace the gasket. Consult your dishwasher’s manual for specific instructions or seek professional help

Step 2: Check Your Dishwasher Float

If you are wondering what is the dishwasher float? Then we’ll tell you, the dishwasher float is a small, round device located in the bottom of the tub.

This element of the dishwasher is there to monitor the water level inside the appliance. If the float is stuck or malfunctioning, it can cause the dishwasher to overfill and leak. 

How To Inspect The Dishwasher Float?

1. Remove the bottom rack of the dishwasher to access the float assembly
2. Gently lift the float arm up and down. It should move freely without any obstructions
3. If it’s stuck, clean the area around it and try again
4. If the float is damaged or not moving properly, you may need to replace it

Step 3: Examine Your Drain Hose

A clogged or damaged drain hose is another common culprit for dishwasher leaks. The drain hose is responsible for removing wastewater from the dishwasher to the drain or garbage disposal. 

How To Inspect A Dishwasher Drain Hose?

1. Remove the lower panel or kickplate at the front of the dishwasher to access the drain hose
2. Carefully inspect the hose for any visible signs of damage, like cracks or leaks. If you find any, it will need to be replaced
3. Check for clogs by disconnecting the hose and running water through it. If there is a blockage, use a pipe cleaner, wire, or other to remove it

Remember professional dishwasher installation can prevent issues like this, assuring your appliance parts have the right setup to function properly. 

Step 4: Check The Inlet Valve

The inlet valve controls the flow of water into the dishwasher. A malfunctioning inlet valve can result in water leaks during the dishwashing cycle

How To Inspect Your Dishwasher Inlet Valve?

1. Check your manual for the inlet valve location, they are usually on the front panel
2. Remove the bottom front panel of the dishwasher to access the inlet valve
3. Inspect the valve for any visible signs of damage, such as cracks or leaks
4. If the valve is damaged, you will need to replace it. Consult your dishwasher’s manual for specific instructions

Step 5: Check The Dishwasher Tub

If you’ve checked the components mentioned above and still can’t find the source of the leak, it’s time to inspect the dishwasher tub itself. 

Cracks or damage to the tub can cause leaks that are more challenging to fix. 

How To Check A Dishwasher Tub?

1. Carefully examine the interior of the dishwasher tub for any visible cracks, holes, or damage
2. Dishwasher tubs are a considerable piece of the appliance so this could be a more difficult repair
3. If you find any significant damage to the tub, it may be best to consult a professional technician for this dishwasher repair or consider replacing the appliance altogether 

Say Goodbye To Your Leaking Dishwasher 

A leaking dishwasher can be a nuisance, but with some careful inspection and the right steps, you can often identify and fix the issue yourself. 

By checking these different parts of the appliance you can narrow down the source of the leak, which is the essential issue to fix, then take the necessary steps to repair or replace the faulty components. 

Remember to check your dishwasher’s manual for specific guidance on where parts are, repair suggestions, replacement parts, and procedures.
