Miele Dishwasher F4155

Miele error code F4155 indicates: The device interrupts the spinning phase and displays a drain error; the laundry remains excessively damp..

The primary root cause for Miele code F4155 is: A drain problem specifically manifests itself before or during the spin cycle, often due to a partial obstruction or a weakened pump..

To resolve error code F4155: 1. Turn off the machine. 2. Perform a complete check of the drain circuit, including the filter, the tank-pump hose and the drain pipe. 3. Make sure that the pressure switch is working correctly and is not giving false residual water level information. 4. Test the drain pump under load for effectiveness and replace if necessary.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Miele code F4155 persists, the physical component causing A drain problem specifically manifests itself before or during the spin cycle, often due to a partial obstruction or a weakened pump. 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.
