Favorit i30

Favorit error code I30 indicates: Error code i30 is displayed on the dishwasher control panel..

The primary root cause for Favorit code I30 is: The connecting hose from the sump to the pressure switch does not maintain a continuous upward slope, lying horizontally or sagging slightly and forming a water trap. Accumulated water or condensate inside the hose falsely triggers the pressure switch..

To resolve error code I30: Disconnect mains power, drain any residual condensate from the pressure switch hose, and secure the connecting hose to the main drain hose using a cable tie to guarantee a continuous upward gradient and prevent sagging.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code I30 persists, the physical component causing The connecting hose from the sump to the pressure switch does not maintain a continuous upward slope, lying horizontally or sagging slightly and forming a water trap. Accumulated water or condensate inside the hose falsely triggers the pressure switch. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
