Why is My Dishwasher Leaking?
Technically Reviewed by Oleg Chudnovski, CEO on Mar 25, 2025 | Written by Igal Geiler
A leaking dishwasher can be attributed to various factors, commonly stemming from issues with the door seal, pump assembly, or inlet valve. A damaged or worn-out door gasket may allow water to escape during the wash cycle, while a malfunctioning pump assembly can result in leaks during drainage. Additionally, a faulty inlet valve may lead to overfilling and subsequent leakage. Regular inspection of these components, addressing any signs of wear or malfunction, can help prevent and resolve dishwasher leakage problems.

How To Repair A Leaking Dishwasher
A dishwasher leaking from the bottom can lead to significant structural damage and costly repairs if not addressed promptly. When faced with such issues, it is crucial to consider both reasons behind the leakage and the necessary steps for effective repair. Professional assistance may be required for complex problems, and obtaining the dishwasher’s model number can expedite the process of finding suitable replacement parts.
Reasons for Dishwasher Leakage
Leakage in a dishwasher often originates from a malfunctioning seal pump, which is responsible for water circulation and drainage. The pump, located at the bottom of the dishwasher, consists of compartments for draining and wash circulation. Components like the chopper blade, drain impeller, and solenoid-operated diverter are essential in ensuring the dishwasher functions correctly. Additionally, seals within the pump housing and the vinyl door gasket can degrade over time due to exposure to detergents and may require replacement.
Steps and Actions for Dishwasher Repair
To address dishwasher leakage, start by inspecting the pump housing and seals for any signs of wear or damage. Remove the access panel at the bottom front of the sink to facilitate a thorough examination. If leakage persists from the front of the dishwasher, scrutinize the door gasket, ensuring it forms a proper watertight seal around the tub or door. Regularly check the door’s alignment with the tub opening, especially in models with rubber baffles at the bottom corners. Another critical area to examine is the water inlet valve, as both cold and hot water supplies must be inspected for potential leaks.
