Dishwasher is leaking


A leaking dishwasher can be a frustrating and potentially damaging issue in your kitchen. Not only does it create a mess, but it can also lead to water damage to your flooring and cabinets if left unaddressed. However, before you panic and call a repair technician, there are several steps you can take to diagnose and potentially fix the problem yourself.

Common Causes of Dishwasher Leaks

  1. Door Seal or Gasket: The most common cause of a leaking dishwasher is a damaged or worn door seal or gasket. Over time, these rubber components can deteriorate, allowing water to escape during the wash cycle.
  2. Faulty Inlet Valve: The inlet valve is responsible for controlling the flow of water into your dishwasher. If it malfunctions or has a loose connection, it can lead to leaks.
  3. Loose or Damaged Hose Connections: Dishwashers have several hoses connected to them, including the water supply hose and the drain hose. If any of these hoses are loose, damaged, or improperly connected, they can cause leaks.
  4. Cracked or Damaged Tub: In rare cases, the dishwasher’s tub itself may have cracks or damage that allow water to escape during a cycle.

Steps to Diagnose and Fix a Leaking Dishwasher

  1. Turn off the Power: Before you begin any troubleshooting, ensure the dishwasher is unplugged or the power is turned off at the circuit breaker. Safety first!
  2. Inspect the Door Seal or Gasket:
    • Carefully examine the door seal or gasket for any visible signs of damage, such as cracks, tears, or mold.
    • If you find damage, replace the seal or gasket with a new one. Most are relatively easy to install and can be purchased from appliance parts stores or online.
  3. Check Hose Connections:
    • Inspect the water supply hose and the drain hose for any visible issues.
    • Ensure all hose connections are secure. Hand-tighten any loose connections, but be cautious not to overtighten and cause damage.
    • Replace any damaged hoses with new ones.
  4. Examine the Inlet Valve:
    • Inspect the inlet valve for any signs of leaks, corrosion, or loose connections.
    • If you notice any problems, consider replacing the inlet valve. Consult your dishwasher’s manual or manufacturer’s website for specific instructions.
  5. Test the Dishwasher:
    • After addressing any visible issues, run a short wash cycle with the dishwasher empty.
    • Monitor the dishwasher closely to see if the leak persists. If it does, turn off the dishwasher immediately to prevent further damage.
  6. Tub Inspection:
    • If the leak continues after checking and addressing the previous components, consider examining the dishwasher’s tub for any cracks or damage.
    • If you find any issues with the tub, it may require professional repair or replacement.


A leaking dishwasher repair can be a nuisance, but with careful inspection and some DIY troubleshooting, you may be able to identify and address the problem yourself. Remember to prioritize safety by turning off the power before working on your dishwasher. If the issue persists or you’re uncomfortable with any of the repair tasks, it’s always a good idea to consult a professional dishwasher repair technician to prevent further damage and ensure the appliance’s proper functioning.
