How to Fix Bosch Dishwasher Error Code E24

1. 1

   Clean the drain filter system

   Remove the bottom rack. Unscrew the coarse filter (twist counterclockwise), then lift out the flat fine mesh filter. Rinse both thoroughly under running water using a brush.

2. 2

   Check the drain hose

   Pull the dishwasher out slightly and trace the drain hose. It should loop up to the underside of the counter and not be kinked.

3. 3

   Check garbage disposal

   Run the disposal before starting the dishwasher. If newly installed, check that the knockout plug was removed.

4. 4

   Check pump impeller

   If filter is clean and hose is clear, reach into the sump and feel around the pump opening for broken glass or hard debris blocking the impeller.

   ⚠️ Use gloves — broken glass may be present.
