What Bosch E26 error means on your dishwasher
Error code E26 indicates a fault with the diverter motor or diverter valve assembly. The diverter directs water flow between the upper and lower spray arms during the wash cycle. When the diverter motor cannot reach its target position or the control board doesn’t receive position feedback, E26 is triggered. If you encounter the bosch e26 error, professional Bosch dishwasher repair may be needed.
Symptoms
- Poor cleaning results — only the top or bottom rack gets cleaned properly
- The dishwasher may stop mid-cycle with E26 on the display
- You may hear clicking or grinding sounds from the base of the dishwasher during cycle changes
- Water spray from one level is noticeably weaker than the other
Common causes
- Debris in the diverter valve — food particles, broken glass, or foreign objects jam the valve mechanism
- Failed diverter motor — the small motor that rotates the valve burns out or seizes
- Position sensor fault — the feedback sensor that tells the control board the valve’s position has failed
- Wiring issue — a loose or corroded connector between the diverter motor and the control board

Troubleshooting steps you can try
- Clean the filter system — remove and clean the main filter and mesh filter at the base of the tub. Debris from the filter area can migrate to the diverter.
- Reset the dishwasher — power cycle by turning off the breaker for 5 minutes. A one-time motor stall can sometimes be cleared.
- Run an empty cycle — run a short cycle with no dishes to see if E26 reappears without a loaded tub.
- Check Bosch support — visit Bosch’s official dishwasher support page for model-specific troubleshooting guides and tech notes.
When to call a technician
If E26 persists after cleaning and resetting, the diverter motor or valve assembly needs inspection. The diverter is located inside the sump assembly at the base of the dishwasher and requires partial disassembly to access. A technician can test the motor, check for mechanical obstruction, and replace the component if needed. Codes may vary by model generation and series. Schedule a certified Bosch technician for fast, reliable diagnosis and repair.
