Why is My Dishwasher Leaking?

Why is My Dishwasher Leaking?

If your dishwasher has suddenly sprung a leak, don’t call a repair technician just yet. Some of the most common culprits of dishwasher leaks can be repaired with DIY solutions. Check out why your dishwasher might be leaking, along with how to detect and fix the problem.

Why Does My Dishwasher Leak?

Before you get started, lay down towels to soak up water and prevent slipping.

Note: If the leak happens when you run the kitchen sink, this indicates a drain pipe issue. Raise the dishwasher drain pipe above the level of the sink drain to solve the problem.

If the leak happens when the dishwasher runs, here are the possible problems to troubleshoot:

  • Leaky gasket: Water on the kitchen floor in front of the dishwasher could indicate leaking door gasket. It’s easy to find out – simply open the dishwasher and check the seal around the door. If you see ripped or worn out sections, replace the gasket before you run the appliance again.
  • Faulty door latch: The latch is what holds the dishwasher closed during a cycle. If it’s loose, water may seep out. You could have a faulty door latch if the dishwasher opens too easily. A new latch should fix the problem.
  • Incorrect detergent: Using dish soap or laundry detergent may cause excessive suds, forcing soap and water out of the door. Only use dishwasher detergent to prevent this problem.
  • Cracked hoses or faulty valves/hose connections: If water flows out from under the dishwasher, you could have a water hose or valve issue. Unplug the dishwasher or turn off the circuit breaker. Remove the toe kick from under the dishwasher door to access the water inlet valve, recirculation hose, drain hose, and other components. Run your hand along various hoses to feel for water. Also, look for loose connections, corrosion, or a bad solenoid valve. To stop the leak, you may need to replace any faulty parts you find.
  • Leaky pump seal: While you’re looking under the dishwasher, check the seal around the water pump. You know it’s leaking if you see water dripping from the pump housing or motor. To remedy this problem, remove the pump and replace the rubber seal.
  • Float switch problem: If the dishwasher tub gets too full, the doors are more likely to leak. The purpose of the float switch is to prevent the dishwasher from overfilling with water. If the float switch is caught on something, it may not work properly. Replacing this mechanism should solve the problem.
  • Drainage issue: If the water doesn’t drain adequately during a dishwasher cycle, this can cause the water level to rise higher than intended. Check the filter at the bottom of the dishwasher tub for a clog that could be preventing proper drainage.
  • Dishwasher sitting crooked: The appliance must sit level to work correctly. Set a carpenter’s level on the rail where the bottom rack rolls to see if the dishwasher is level from front to back. Set the level on the open door to see if the dishwasher is level from left to right. If needed, adjust the leveling screws on the front legs using your fingers or an open-end adjustable wrench until the appliance is no longer crooked.
