Can I fix Bosch code E24 myself?

Start with these safe checks: Check the drain hose under the sink isn't kinked or damaged. Remove the filter and make sure the pump cover underneath isn't loose. If the drain hose connects to a garbage disposal, make sure the knockout plug was removed from the disposal's dishwasher inlet. If it still won't drain, contact Bosch support or a technician.

When should I call a technician for code E24?

If it still won't drain, contact Bosch support or a technician. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
