Bosch dishwashers E24 error

The dishwasher is not draining properly.

E24

What this code can mean

Bosch associates E24 with a blocked drain filter or hose, a loose pump cover, or an unremoved garbage-disposal knockout plug.

Safe first checks

  1. 1
    Power off the dishwasher before inspecting user-serviceable parts.
  2. 2
    Clean the filter and check that the pump cover is seated as described in the model manual.
  3. 3
    Check visible drain connections for kinks or installation problems.

Possible causes

  • Drain filter or hose is blocked.
  • Pump cover is loose.
  • A new garbage disposal still has its dishwasher knockout plug.
  • The siphon or drain connection is incorrect.
Stop conditions
  • Stop if water is leaking or electrical components are wet.
  • Request service if the pump area is inaccessible or the code returns.

Use Bosch support or an authorized servicer if the documented drain checks do not clear E24.
