Answer to continue safely
Is it safe to keep using?
No. The dishwasher cannot fill properly. Running it wastes water and energy with no cleaning action. Fix the drain path before next use.
Can I reset the code?
Yes. If a missing high loop caused siphoning, installing one resolves E24 permanently. A stuck drain relay requires board repair.
When to stop immediately?
Stop if you notice: Standing water is present after every cycle regardless of reset, Drain pump makes a high-pitched whine but water level does not change.
Symptoms You May Notice
Water drains continuously during fill
The dishwasher fills with water but simultaneously pumps it out, creating a fill/drain loop that prevents the cycle from proceeding.
Cycle never advances past fill phase
The control board keeps the fill valve open because the water level sensor never registers a full tub, as water drains out as fast as it enters.
Running water sound is constant
Both the fill valve (hissing) and drain pump (humming) sounds are audible simultaneously, which is abnormal.
E24 appears after extended fill attempt
The board times out after failing to achieve proper water level within the maximum fill time (typically 5-8 minutes) and displays E24.
Possible Causes
Drain valve stuck open or check valve failed
The one-way check valve in the drain path has failed or the drain solenoid is stuck open, creating a siphon effect that drains water as it enters.
Requires ProfessionalDrain hose installed without high loop
If the drain hose runs downhill from the dishwasher to the disposal without a high loop or air gap, gravity siphons water out during fill.
DIY PossibleControl board drain relay fault
The relay that controls the drain pump has failed closed, keeping the pump energized even during fill and wash phases.
Requires ProfessionalSafe Checks You Can Do
-
1
Check drain hose routing
Look under the sink and verify the dishwasher drain hose loops up near the underside of the countertop before going down to the disposal or drain. This high loop prevents siphoning.
The top of the loop should be at least as high as the flood level of the sink.

Listen for drain pump during fill
Start a new cycle and listen carefully. You should hear only the fill valve hissing. If the drain pump is also running simultaneously, a control board relay fault is likely.
The drain pump makes a distinct low humming sound different from the fill valve hiss.
When to Call a Professional
Contact a qualified technician if:
- Drain pump motor tests open on a multimeter — replacement required
- Impeller is cracked or broken and the full pump assembly must be replaced
- Drain hose routing requires pulling the unit from the cabinet to correct
