What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Stop the cycle if safe and check for standing water before any filter access.
- Clean only the user-accessible filter areas described by Bosch, with power disconnected and the exact model instructions available.
- Inspect the exposed drain hose without pulling out the dishwasher; stop if access or reassembly is uncertain.
Applicability
Regional guidance · Bosch dishwashers covered by the U.S. error-code guide · United States
This scope follows Bosch's U.S. dishwasher error-code guide; limit owner action to the user-accessible filter instructions for the exact model and do not access the pump area.
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.
Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
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 continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- 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
- Blocked drain pump or loose pump cover
- Kinked or obstructed drain hose
FAQ
What does Bosch Dishwasher code E22 usually mean?
Commonly logged when the dishwasher filter is blocked or needs cleaning. Model context matters: Bosch's U.S. error-code guide groups E22 and E-22 with blocked-filter guidance; longer display variants should still be checked against the exact model manual.
Can I keep using the dishwasher with code E22?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Disconnect power before accessing drain-area components.
When should I call a technician for Bosch E22?
Call Bosch support if E22, E-22, or E9240 returns after safe filter cleaning. A qualified technician may check Filter assembly, Drain pump cover, and Drain pump against the model's service information before treating any part as failed.
