Dishwasher leaks can happen for several reasons, from clogged filters to faulty seals. Let’s go through the most common causes and how to fix them quickly.

1. Check for Loose or Blocked Hoses

If your dishwasher is leaking from the back, the water supply or drain hose could be loose or clogged.

Quick Fix:

• Turn off the water supply and unplug the dishwasher.
• Inspect the hoses for cracks, blockages, or loose connections.
• Tighten any loose fittings or replace damaged hoses if necessary.

2. Clean the Filter and Drain

A clogged filter or blocked drain can cause water to back up and spill out of the dishwasher.

Quick Fix:

• Remove the bottom rack and locate the filter.
• Rinse it under warm water and remove any food debris.
• Check the drain for blockages and clear them if needed.

3. Inspect the Door Seal (Gasket)

A damaged or worn-out door gasket can cause water to leak out during a cycle.

Quick Fix:

• Open the dishwasher and inspect the rubber seal around the door.
• If it’s worn, cracked, or has food buildup, clean it with warm soapy water.
• If the seal is damaged, replace it with a new one.

4. Make Sure the Dishwasher Is Level

If your dishwasher isn’t level, water can pool and leak out.

Quick Fix:

• Use a spirit level to check if the dishwasher is sitting evenly.
• Adjust the legs by turning them clockwise or anti-clockwise until the machine is level.

5. Use the Right Detergent

Using regular dish soap instead of dishwasher detergent can create too many suds, leading to leaks.

Quick Fix:

• Only use detergent specifically designed for dishwashers.
• If you’ve accidentally used the wrong soap, run an empty cycle with vinegar to clear out excess suds.

6. Check for a Faulty Float Switch

The float switch prevents overfilling. If it’s stuck, your dishwasher may take in too much water and start leaking.

Quick Fix:

• Locate the float switch (usually a small plastic piece at the bottom of the tub).
• Gently move it up and down to check if it’s stuck.
• Clean any debris around it to ensure it moves freely.
