Before you begin
Safety first
Standing water and pump-area debris can be hot or sharp. Disconnect electrical power before reaching into the sump or handling the pump cover.
- Cancel the cycle and let hot water cool before opening the filter area.
- Switch off and unplug the dishwasher before touching the pump area.
- Wear cut-resistant gloves because broken glass may be hidden below the filter.

Common paths to check
These are source-backed possibilities, not probability estimates for your specific unit.
- 01 The filter, drain pump area, air gap, or drain hose is blocked by debris.
- 02 The drain hose is kinked or sharply bent behind the dishwasher.
- 03 The drain-pump cover is loose or not fully locked into position.
- 04 A new garbage disposer still has its dishwasher inlet knockout plug installed.
Decision path
Safe checks, in order
- 1
Inspect the visible drain path
With power disconnected and the water cool, remove the filter only as described in the model manual, clear visible standing water and loose debris, and confirm the pump cover is seated.
Expected: The filter area is clear and the pump cover locks fully into place.
If not resolved: Continue to the external drain-hose, air-gap, and disposer checks.
- 2
Check the hose and air gap
Inspect the accessible drain hose for a sharp bend. If the sink has an air gap, check it for debris without dismantling any hard-wired appliance parts.
Expected: The hose has a smooth path and the air gap is not visibly blocked.
If not resolved: Have a qualified service provider inspect the drain pump and concealed plumbing.
- 3
Check a new disposer connection
If a garbage disposer was recently installed, ask the installer to confirm that its dishwasher-inlet knockout plug was removed before the drain hose was connected.
Expected: The disposer inlet is open and the drain hose is correctly attached.
If not resolved: Stop repeated reset attempts and arrange service if E24 returns.
Reset and test
- Restore power only after all covers and filters are correctly reinstalled.
- Use the model-specific cancel or reset procedure in the owner manual.
- Run a short rinse cycle and watch for normal drainage and leaks.
Important: A reset only clears the display; it does not remove an obstruction or repair a failed drain component.
Escalation point
Stop and arrange service when
- Water leaks from the cabinet, wiring, or hose connection.
- The pump area contains glass that cannot be removed without disassembly.
- E24 returns after the accessible drain path is confirmed clear.
