Common Causes of Dishwasher Leaks

1. Faulty Door Seal:
   • Check for Wear and Tear: Inspect the rubber gasket around the dishwasher door for cracks, tears, or debris.
   • Cleaning: Clean the gasket with mild soap and water to remove any buildup.
   • Replacement: If the gasket is damaged, replace it with a new one.
2. Clogged Drain Hose:
   • Inspect the Hose: Check the drain hose for kinks, bends, or blockages.
   • Clear the Clog: Use a plumber’s snake or a wet/dry vacuum to clear any obstructions.
   • Ensure Proper Drainage: Make sure the drain hose is securely connected to the drainpipe.
3. Worn-Out Spray Arms:
   • Check for Obstructions: Inspect the spray arms for food particles or mineral deposits.
   • Clean the Spray Arms: Remove the spray arms and clean them with a brush or vinegar solution.
   • Replace Damaged Arms: If the spray arms are damaged or worn out, replace them with new ones.
4. Loose Water Supply Connection:
   • Tighten the Connection: Ensure that the water supply line is securely tightened to the dishwasher and the faucet.
   • Check for Leaks: Inspect the connection for any signs of leaks.
   • Replace the Connection: If the connection is damaged, replace it with a new one.
