Questions people ask
Does Bosch E24 always mean the drain pump is bad?
No. Bosch E24 often comes from a blockage before the pump fails. Clean the filter, pump cover, air gap, and hose path before assuming the pump needs replacement.
Can a clogged garbage disposal cause Bosch E24?
Yes. If the dishwasher drains into a disposal, a clogged disposal or an unremoved knockout plug can prevent draining and trigger E24.
