The rubber door gasket is the primary cause of dishwasher leaks. Over time, it can degrade, tear, or become misaligned.

How to Fix:

2. Inspect the gasket: Look for visible tears, flattening, or food debris buildup.
   
3. Clean thoroughly: Use a mild detergent and soft cloth to remove grease.

5. Replace if necessary: Order the exact model replacement and precisely install it in the channel.
   

2. Faulty Hose Connections

The water inlet and drain hoses can loosen over time or develop cracks.

How to Fix:

1. 
   
2. Locate connections: Typically found at the back/bottom of the unit.
   
3. Inspect hoses: Check for cracks and tightness of clamps.
   
4. Tighten connections: Use an adjustable wrench to secure all hose clamps.
   
5. Replace damaged hoses: If worn, install new hoses with proper fittings.
   

3. Blocked Drainage System

A blocked filter, drain hose, or pump can cause water to overflow and leak.

How to Fix:

4. Inspect the pump: Remove debris from the impeller area.
   
5. Test drainage: Run a rinse cycle to verify proper water flow.
   

4. Faulty Float Switch

The float switch regulates water level and can cause overfilling when defective.

How to Fix:

1. 
   
2. Locate the float: Usually a small plastic device in the tub base.
   
3. Check movement: Ensure it moves freely up and down.
   
4. Clean the mechanism: Remove any debris obstructing operation.
   
5. Test functionality: Manually lift the float during a cycle to stop water flow.

The plastic interior tub can develop hairline cracks from wear.

How to Fix:

1. 
   
2. Dry the interior: Wipe completely with towels.

4. Repair small cracks: Use dishwasher-safe epoxy resin.
   
5. Consider replacement: Large cracks may require a new dishwasher.
   

6. Leaking Water Inlet Valve

The inlet valve can malfunction, causing continuous water flow.

How to Fix:

1. 
   
2. Shut off water supply: Close the valve under the sink.
   
3. Disconnect hoses: Have towels ready for residual water.
   
4. Test the valve: Check for dripping when in off position.

An improperly installed unit can cause poor drainage and leaks.
