Answer to continue safely
Is it safe to keep using?
No. A failed wash motor means dishes will not be cleaned and standing water may remain in the tub, creating bacterial growth.
Can I reset the code?
Yes. If debris in the impeller caused the stall, clearing it and power cycling may resolve E1. Motor burnout requires professional replacement.
When to stop immediately?
Stop if you notice: Tub is completely dry after two fill attempts, You hear a buzzing valve but water flow does not start.
Symptoms You May Notice
Dishwasher fills but does not start washing
Water enters the tub but the wash motor never activates. The unit sits with water in it and eventually displays E1.
No motor sound during wash cycle
The normal humming sound of the wash motor is completely absent, though the drain pump may still function.
Cycle timer advances without action
The control board counts down cycle time but no washing motion occurs — dishes come out untouched and dirty.
Water leaks from door seal area
Standing water in the tub may reach levels high enough to seep past the door gasket if the unit attempts multiple fill cycles.
Possible Causes
Failed wash motor or motor winding
The main circulation pump motor has burned out or developed an open winding, preventing it from generating the water pressure needed for spray arm operation.
Requires ProfessionalWash motor capacitor failure
The start capacitor for the wash motor has failed, preventing the motor from generating enough starting torque to begin spinning.
Requires ProfessionalBlocked or seized pump impeller
Debris such as glass fragments, food particles, or a dislodged utensil has jammed the wash pump impeller, preventing rotation.
DIY PossibleSafe Checks You Can Do
-
1
Check for debris in the sump
Remove the lower spray arm and the filter assembly beneath it. Inspect the sump area for broken glass, food debris, or objects that could block the impeller.
A toothpick or small bone fragment wedged in the impeller is one of the most common causes of E1 on Dacor DDW models.

2
Power cycle and listen for motor
Turn off the breaker for 2 minutes, restore power, and start a quick wash cycle. Listen carefully for any humming, clicking, or buzzing from the motor area at the bottom of the unit.
A buzzing sound without rotation means the motor is getting power but cannot spin — likely a seized impeller or failed capacitor.
When to Call a Professional
Contact a qualified technician if:
- Inlet valve screen is clean but still no fill after reset
- Water pressure at supply hose tests below 20 psi
- Pressure sensor or wiring harness replacement is needed
