E24 Bosch Dishwasher Error Code

DIY

What does E24 mean?

United States

The dishwasher is not draining properly, typically due to a blocked drain filter, a loose drain pump cover, a kinked hose, a clogged airgap, or a garbage-disposal knockout plug left in place.

United Kingdom

The appliance is not draining properly due to a blockage.

Common causes

The manufacturer support page points to these conditions for this code:

  • A blocked or dirty filter
  • A kinked, bent, or pinched hose
  • A blocked, kinked, or incorrectly installed drain hose or standpipe
  • A loose or missing drain pump cover

What to check first

  1. Check the inlet hose isn’t kinked;
  2. remove the filter and make sure the drain pump cover underneath isn’t loose;
  3. if the drain hose connects to a garbage disposal, confirm its knockout plug was removed.

Safety

  • Unplug the appliance before opening the filter, pump cover, or drain area, and expect water to come out.

When to call a professional

If the problem persists after the checks, book an engineer.
