What i41 Means
i41 means no pressure sensor signal. The service manual sets it when the signal from the analog pressure sensor is lost for more than one second; the program is aborted and the code shown. Checks are the sensor harness and its connection to the board, then the sensor itself.
Common Causes of i41
- Pressure sensor connector loose
- Sensor harness damaged
- Pressure sensor failed
🔧 One Safe Check You Can Try
Switch off the breaker for a minute and restart. If i41 or i40 returns, the dishwasher needs service; the sensor is under the tub.
⚠ Why You Shouldn't Go Further Than That
- The sensor and harness are reached from under the dishwasher.
- Without a level signal the dishwasher cannot fill safely.
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.
