Thermador Dishwasher E24: Drainage Code and Safe Checks

Thermador dishwasher code E24 is associated with a drainage problem on applicable models. The exact message and diagnostic steps can vary by model. Consult the owner’s manual for your dishwasher and do not assume the drain pump itself has failed.

Safe Checks

• Stop the cycle and check the manual for the approved filter-cleaning procedure. Clean only user-serviceable filters and reinstall them as directed.
• Look for a visible kink in an accessible drain hose without moving the dishwasher or disconnecting plumbing.
• If there is an air gap at the sink, check for a visible obstruction only as allowed by its instructions.
• If the pump cover is described as user-removable in your exact manual, verify it is seated as directed; do not reach into a pump or use tools.

Do not remove panels, access wiring, force the pump, or attempt an internal repair. If E24 persists after the manual-approved checks, or water is leaking, stop using the dishwasher and arrange qualified service. Provide the full model number and code.
