What the display tells you

What does Bosch E24 / E-24 mean?

Bosch's current dishwasher code page lists several possible E24 contexts, including a blocked or loose pump cover, a sharply bent drain hose, or a restriction in the air gap or drain path. The exact relevant check depends on the installed model and its manual.

A useful distinction

This is the condition described by the maker—not a remote diagnosis of your appliance. A code can point to a system or symptom without confirming which part, if any, needs replacement.

Safe first checks

Begin with what you can see and with instructions for the exact model. Do not skip the maker's cautions to clear the display faster.

  1. Record E24 exactly and note the model and E-Nr from paperwork or a safely visible rating label.
  2. If the drain hose is visible without moving the installed dishwasher, look for an obvious kink. Do not disconnect a hose or remove a pump cover based on this general summary.
  3. Use Bosch's exact model instructions for any owner-accessible filter step; otherwise arrange service, especially if water remains in the tub.

When to stop and get help

Safety boundary

Stop if water is leaking, standing near electrical parts, or the dishwasher must be pulled from cabinetry to inspect it. Contact Bosch or a qualified technician if E24 remains after the model-approved checks.

Why the model number matters

Bosch's guidance presents multiple E24 possibilities and steps. Pump-cover access, drain routing, and owner-serviceable components vary by model; do not treat one procedure as applicable to every Bosch dishwasher.

Look for the full model identifier in the owner's paperwork or on a label that is safely visible without moving, tipping, or opening the appliance. Use that identifier when you open the manufacturer source below.
