Understanding the Problem
If your Maytag dishwasher (model series PDC3) is leaking, the leak can come from several common places: the door seal, the pump/sump area, water inlet or drain hoses, or the dispenser. Leaks may appear as a steady drip, puddles under the dishwasher, or water on the cabinets or floor after a cycle. Because dishwashers use pressurized water, small failures in seals, clamps, or plastic parts commonly cause leaks that worsen with use. Start by isolating where the water is originating — top of the door, front bottom, underneath the dishwasher, or behind it. Safety first: turn off electrical power at the breaker and shut the water supply if you’re going to pull the dishwasher forward. Many leaks are repairable with a replacement gasket, hose clamp, or pump seal; others (cracked tub or failing pump housing) may require replacing assemblies. If you see water near the control area, or electronics are wet, stop using the appliance and dry/inspect components to avoid electrical damage.
Common Symptoms
Puddles or damp floors beneath the dishwasher, water seeping from the bottom front edge of the door, water behind the appliance, dishwasher stops mid-cycle or shows water-related error codes, rust or water stains on cabinetry
Common Causes
- Worn, torn or improperly seated door/boot gasket
- Failed pump/sump seal or cracked pump housing
- Loose or split water inlet or drain hose / bad hose clamp
- Detergent dispenser or inner door cracks allowing water to escape
- Stuck float or faulty float switch causing overfill
- Poor leveling or installation (dishwasher not flush with gasket contact)
- Clogged drain leading to overflow or back-splash
- Cracked tub (rare, usually plastic tubs) or corroded seals

Helpful Repair Tip
To pinpoint the source, place dry paper towels or cardboard under and around the dishwasher, then run a short rinse cycle while watching. The wettest towel/location shows the leak origin — if it’s under the sump/pump area, suspect the pump/sump or connections; at the front bottom, suspect door seal or inner door panel.
Frequently Asked Questions
How do I know if the leak is coming from the door gasket or the pump?
Place a dry towel under the front of the dishwasher and another directly under the base where the pump/sump sits. Run a short rinse cycle and watch where the towel gets wet first: water at the front edge of the door usually means the door gasket or inner door panel; water under the center or slightly to one side under the unit typically indicates the pump/sump assembly or hoses. If in doubt, pull the unit forward for a visual inspection with the power off.
Can I keep using the dishwasher if it's leaking a small amount?
You should not keep using a leaking dishwasher for long. Even a small leak can damage flooring and cabinets, and water contact with electrical parts can be dangerous. If the leak is minor and you can catch/contain the water while you obtain parts, you might run a temporary short cycle, but best practice is to turn off power and water and repair or replace the faulty component promptly.
