Fixing a Leaking Dishwasher

If you find that water is pooling underneath your dishwasher on a regular basis, you most likely have a leak in need of repair. In this article, we share the most common causes of dishwasher leaks and repair strategies.

Using Unsuitable Products

Make sure you use a dishwasher-suitable product rather than a regular dish soap solution. Products not suitable for use in the dishwasher can cause a build-up of pressure inside the machine that could lead to a leak.

Door Latch and Gasket Leaks

If the dishwasher door is failing to seal properly, you will notice that the water pools directly underneath the door. Firstly check the latch to see if it is not properly aligning or loose. On occasions, you may be able to fix it yourself by simply straightening or securing the latch.

The rubber sealing around the door, known as the gasket, is designed to stop leaks. If it becomes damaged, it may need to be replaced by a professional.

Hose Leaks

Water flows in and out of the dishwasher through two hoses: the drain hose and the water supply hose. If these hoses come loose, this may cause a pool of water on the floor. You could also want to try to tighten the screws, nuts, and connections to the sink valve or inlet valve, or replacing the thread seal tape.

Damaged or Corroded Tubs

Your dishwasher is fitted with a tub, the bottom of which may corrode over time. Whether damage is repairable or not depends on the severity of the damage. If you are unsure on how severe the issue is, it is best to refer the issue to a service technician to avoid more damage.

Pump Leaks

You can inspect the dishwasher pump for leaks in the body or seal (it is located under the lower front panel above the motor and attached to the drain hose). If you notice damage to the body or seal, consult a professional for repair or part replacement.

Safety Tips

Always disconnect the dishwasher from power and water supplies BEFORE beginning repairs.

When removing the dishwasher from underneath a countertop for closer inspection, make sure that it is unplugged and unscrewed from the counter top. You may also need to disconnect the drain hose.
