Bosch Dishwasher Error Code E24 Meaning, Causes, and Fix Guide

What Does Bosch Dishwasher Error Code E24 Mean?

Bosch dishwasher error code E24 indicates a drainage problem. The dishwasher detects restricted or slow water flow while draining and stops the cycle to prevent pump damage or water backup.

Simply put, E24 = water cannot drain out properly.

Common Causes of Bosch Dishwasher E24 Error

Clogged Drain Filter
Food particles, grease, and residue block the filter and slow down drainage.

Blocked Drain Hose
A kinked, twisted, or clogged drain hose prevents water from exiting the dishwasher.

Garbage Disposal Connection Issue
If the dishwasher is connected to a garbage disposal, a clog or an unremoved knockout plug can trigger E24.

Drain Pump Obstruction
Small objects like seeds, glass fragments, or labels can jam the drain pump impeller.

Improper Drain Hose Installation
Incorrect hose height or routing causes water to flow back into the dishwasher.

Grease Buildup Over Time
Grease accumulation inside pipes reduces drainage efficiency.

How to Fix Bosch Dishwasher Error Code E24

Step 1: Turn Off Power
Unplug the dishwasher or switch off the circuit breaker for safety.

Step 2: Clean the Drain Filter
Remove the bottom rack and take out the filter assembly. Wash it thoroughly under warm water and remove all debris.

Step 3: Check the Drain Pump Area
Sponge out any standing water. Inspect the pump area carefully and remove foreign objects.

Step 4: Inspect the Drain Hose
Pull the dishwasher forward and check the hose for bends or blockages. Straighten or clean the hose if needed.

Step 5: Check the Garbage Disposal Port
Make sure the dishwasher drain inlet on the disposal is clear and the knockout plug has been removed.

Step 6: Run a Test Cycle
Restore power and water supply, then run a short cycle to confirm the error is resolved.
