Answer to continue safely
Is it safe to keep using?
No. Standing water in the tub creates bacterial and odor issues. The unit should not be loaded with new dishes until draining is restored.
Can I reset the code?
Yes. Cleaning the drain filter often resolves E9 immediately. If the drain pump has failed, professional repair is needed.
When to stop immediately?
Stop if you notice: E9 appears on every cycle without exception, A burning smell is noticed during the wash or dry phase.
Symptoms You May Notice
Water remains in tub after cycle ends
The dishwasher completes its wash cycle but standing water remains in the bottom of the tub, several inches deep.
Drain pump does not activate
No sound from the drain pump during the drain phase — the unit is silent when it should be pumping water out.
Gurgling without effective draining
The drain pump activates and makes noise but water level does not decrease, suggesting a blockage downstream.
Foul odor from stagnant water
Standing water that remains in the tub between cycles develops bacterial odor, especially in warm environments.
Possible Causes
Blocked drain hose or air gap
Food debris, grease buildup, or a kinked hose prevents water from exiting the dishwasher through the drain path to the garbage disposal or drain line.
DIY PossibleFailed drain pump motor
The drain pump motor has burned out or seized, preventing it from evacuating water from the tub at the end of each cycle phase.
Requires ProfessionalClogged filter basket or check valve
The fine mesh filter or the one-way check valve in the drain path is obstructed with food particles, preventing water flow.
DIY PossibleSafe Checks You Can Do
-
1
Clean the drain filter
Remove the lower spray arm, then twist and lift out the cylindrical filter assembly. Rinse under running water and clear any food particles or grease from the mesh.
The fine filter should be cleaned monthly on Dacor DDW24 models — this is the most common cause of E9 drainage faults.

Check the drain hose for kinks
Pull the dishwasher out slightly (after disconnecting power) to inspect the drain hose for kinks, compression, or visible blockage. The hose should have a high loop under the counter.
A drain hose without a high loop allows sink water to backflow into the dishwasher.
When to Call a Professional
Contact a qualified technician if:
- Heating element tests open on a multimeter — requires replacement
- Thermal fuse reads no continuity and must be replaced before the unit is used again
- NTC sensor resistance falls outside the 10-50 k-ohm range at room temperature
