Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not open drain or pump areas while the appliance is powered.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Dishwasher filter blocked by food debris
- Filter not cleaned regularly
- Drain-area debris restricting water movement
Basic checks
- Stop the cycle if safe.
- Check for standing water before removing the filter.
- Clean only the user-accessible filter areas described by Bosch.
- Check for standing water after the cycle stops; if water remains, treat the issue as an active drain restriction.
- Inspect the visible drain hose for kinks or crushing; if routing is pinched, correct it before a retry.
Reset or retry steps
- Retry only after the filter is reinstalled correctly and no leak is visible.
When to call a technician
- Call Bosch support if E22, E-22, or E9240 returns after safe filter cleaning.
- Call service if the filter is damaged, stuck, or cannot be seated.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
