Symptoms You May Notice
Dishwasher leaks from bottom during cycle
Water appears on the floor beneath the dishwasher during the wash or rinse phase, originating from the motor area or supply connections.
Spray arms lose pressure mid-cycle
The spray arms start strong but weaken significantly during the cycle as water escapes through the leak point.
E27 triggers flood protection shutoff
The base pan float switch activates due to accumulated leaked water, triggering an emergency drain and cycle halt.
Musty smell from under dishwasher
Repeated small leaks create persistent moisture under the unit, leading to mildew or mold growth on the floor or cabinet.
Possible Causes
Worn wash motor shaft seal
The mechanical seal around the wash pump motor shaft has worn from age or debris, allowing water to drip past during high-pressure operation.
Requires ProfessionalCracked sump housing
The plastic sump that collects water before routing it to the pump has developed a crack from thermal stress or impact, creating a slow leak.
Requires ProfessionalLoose hose clamp on internal connection
A hose clamp connecting the sump to the spray arm supply line or drain hose has loosened from vibration, allowing seepage.
DIY PossibleSafe Checks You Can Do
-
1
Identify leak location
Place paper towels or newspaper under the dishwasher, run a short cycle, then pull the unit forward to see where the paper is wettest. This localizes the leak source.
Front wetness often indicates a door gasket issue; rear wetness suggests internal hose or pump seal failure.

2
Inspect door gasket
Examine the rubber door gasket for cuts, food debris, or areas where it has pulled away from the channel. Clean the gasket and tub lip with warm soapy water.
A displaced gasket at the bottom corners is the most common cause of slow door leaks on Dacor Contemporary dishwashers.
When to Call a Professional
Contact a qualified technician if:
- Outlet voltage measures below 110 V under load — an electrician is needed
- Terminal block connections inside the dishwasher show arcing or melting
