De Dietrich F2

De Dietrich error code F2 indicates: De Dietrich Quattro / Space / DFI Luxury Built-in Dishwasher: Sump water evacuation timeout F2; water remains detected in the bottom sump basin after drain phase timing expires..

The primary root cause for De Dietrich code F2 is: On De Dietrich dishwashers featuring Quattro 4-level hydraulic spray distribution, ICS turbidity assessment, and 42dB acoustic encapsulation: Blocked sink spigot connection, debris in drain pump volute, or open drain pump winding (~180–220 Ω)..

To resolve error code F2: Check sink drain connector and punch out membrane if newly installed. Measure drain pump motor resistance (~180–220 Ω). Press and hold Programme Selection and Start buttons for 5 seconds until all cycle lights illuminate steadily, then switch off power.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if De Dietrich code F2 persists, the physical component causing On De Dietrich dishwashers featuring Quattro 4-level hydraulic spray distribution, ICS turbidity assessment, and 42dB acoustic encapsulation: Blocked sink spigot connection, debris in drain pump volute, or open drain pump winding (~180–220 Ω). 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.
