Does this guide apply to your appliance?

Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.

No exact model number is recorded here. Confirm the code in your appliance manual before following a check.

Likely causes

  • Dirty or blocked dishwasher filter
  • Debris blocking the accessible drain-pump area or a pump cover that is not properly secured
  • Kinked drain hose
  • Clogged air gap or drain connection

What to try

Clean and reinstall the dishwasher filter

Easy
  1. Turn the dishwasher off and disconnect it from power.
  2. Remove the filter according to the owner manual for your Bosch model.
  3. Wash the filter under running water with mild soap and a soft brush.
  4. Reinstall the filter securely, following the model-specific instructions.
  5. Reconnect power and test the dishwasher with a rinse cycle.

This step is marked caution. Stop if you are not qualified to continue.

Check accessible drainage points

Moderate
  1. Turn the dishwasher off and disconnect it from power before checking the pump area.
  2. If standing water remains, inspect only the accessible pump area for loose debris and confirm that the pump cover is fully latched.
  3. Do not reach into debris blindly; broken glass may be present.
  4. Check the drain hose for kinks.
  5. Check the air gap or drain connection for a visible clog, if fitted.
  6. Reconnect power and run a rinse cycle to test drainage.

This step is marked caution. Stop if you are not qualified to continue.

Use the model-specific reset procedure or arrange service

Professional

This is a service referral, not a do-it-yourself repair procedure.

  1. Find the dishwasher’s Model Number/E-Nr. and consult the matching Bosch owner manual for the correct reset instructions.
  2. Perform the model-specific reset only after cleaning the filter and checking the accessible drainage points.
  3. If E22 returns, the dishwasher still will not drain, or you see a leak or electrical fault, stop using the appliance.
  4. Contact Bosch support or a qualified appliance technician for further diagnosis and repair.

This step is marked professional. Stop if you are not qualified to continue.

The code returned or the check did not help?

Avoid repeated resets and do not select a replacement part from the code alone. Record the exact code, full model number, when it appeared, and the checks you tried with their results. Share these details with the manufacturer or service technician.

Disconnecting power does not establish that internal components are safe to touch. This guide does not authorize opening electrical components or bypassing safety devices.
