Quick answer: Bosch dishwasher error code E24: drainage problem: dishwasher not draining properly. The most common cause is drain pump blocked by food, glass, or debris. Try this first — clean the drain filter. If that does not clear it, clear the drain pump.

What causes the E24 error?

  • Drain pump blocked by food, glass, or debris
  • Drain pump cover loose or missing
  • Drain hose kinked, bent, or clogged
  • Sink air gap or garbage disposal connection blocked, including a disposal knockout plug left in on new installs

How to fix Bosch E24 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Clean the drain filter
    Pull out the filter assembly at the bottom of the tub and wash it under running water with mild soap and a soft brush to clear trapped debris.
  2. Clear the drain pump
    Remove the filter to expose the pump cover, lift it off, and remove any standing water and debris around the pump. Snap the cover back on until it clicks firmly into place.
    Safety warning: Debris in the pump can be sharp, such as glass shards; protect your hands.
  3. Check the drain hose and air gap
    Straighten any kinks in the drain hose, clear debris from the air gap, and make sure a newly installed garbage disposal has its dishwasher knockout plug removed.
  4. Reset and test
    Reset the dishwasher per your owner's manual and run a short rinse cycle to confirm the water drains fully.
