What iB0 Means
iB0 is a turbidity sensor code: calibration did not complete within 15 seconds. The program continues as if the dishes were heavily soiled, so cycles run longer and use more water. Checks are the turbidity connection and harness, then the sensor.
Common Causes of iB0
- Turbidity sensor dirty
- Sensor connection loose
- Sensor failed
🔧 One Safe Check You Can Try
Clean the filter and sump; heavy soil around the sensor can upset calibration. Cycles will still clean.
⚠ Why You Shouldn't Go Further Than That
- The sensor is in the sump, reached from under the tub.
- It is not urgent, but running heavy cycles every time uses more water and energy.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
