Bosch Washer - E25 Error Code
The turbidity sensor is reporting invalid or no readings.
Meaning
The turbidity sensor is reporting invalid or no readings.
The Bosch E25 and F25 error codes indicate a problem with the turbidity sensor, which measures water clarity to optimize rinse performance. If the sensor becomes coated with detergent residue, lint, or mineral buildup, or if the wiring becomes loose, the washer cannot accurately determine water quality and triggers E25. This can lead to extended rinse cycles or poor cleaning results.
Symptoms
Causes
Step-by-Step Fixes
- Run a hot wash with no laundry to dissolve residue.
- Use a descaling agent if mineral buildup is suspected.
- Inspect the sensor wiring for loose connections.
- Replace the turbidity sensor if readings remain invalid.
Safety Notes
- Avoid excessive detergent use to prevent residue buildup.
