Possible Causes
Faulty Zeolith heater, Defective Zeolith blower, Wiring fault between Zeolith module and main control, Internal control board error
How to Fix / Troubleshooting
Safety first: Disconnect power before removing side panels.
- Identify Zeolith system: E10 typically appears on Bosch models equipped with Zeolith drying (with a zeolite container on the side of the tub).
- Access Zeolith module: Remove the side panel to expose the Zeolith container, blower, and heater connections.
- Inspect wiring: Check all connectors between the Zeolith module and the main control board for secure fit and signs of heat damage or corrosion.
- Test blower and heater: Use a multimeter to measure resistance of the Zeolith blower motor and heater. Compare to Bosch specs. An open or shorted component must be replaced.
- Control reset: After checks, perform a power reset (breaker off for 10 minutes) and run a test cycle. If E10 returns, the Zeolith module or main control board may require replacement.
