Attempt
The drain pump was replaced
The original E24 interpretation drove the first repair.
Failed-replacement case · Bosch E24
A Complete Drain Did Not Stop E24 from Returning
The new drain pump moved all visible water, yet the code came back. That result weakened a simple drain-obstruction theory and opened a circulation-pump check.
The replacement changed the evidence, not the complaint
- E24 originally led to a drain-pump replacement.
- After replacement, the dishwasher visibly emptied all water.
- No drain blockage was observed.
- E24 returned the following day.
The expert reply redirected the diagnosis toward the circulation pump and specifically suggested checking rotor play. The source stops before that inspection.
A similar symptom can have a different cause on another appliance or model.
Why repeating the drain repair would ignore the new clue
Observed
The tub emptied completely
That made a total drain failure or obvious blockage less coherent with the return complaint.
Next branch
Check circulation-pump rotor play
The discussion noted that this Bosch code can return when the circulation side is the relevant mechanical fault.
The case supports a circulation-pump check, not a confirmed pump failure
The return of E24 despite a complete drain is the decisive clue. It justifies moving beyond the already-replaced drain pump, but the circulation pump remains a supported hypothesis until its rotor and operation are inspected.
No completed second repair was reported.
Verify the full machine sequence before ordering another pump
Record when E24 appears, confirm that the drain remains complete, and have the circulation assembly checked for mechanical play and model-specific faults. Preserve the part number and result of the first pump replacement.

Water and electrical safety: disconnect power and control standing water before accessing either pump. Rotor inspection and energized motor testing are qualified-service work.
