Midea LC

Midea error code LC indicates: Midea Lunar Dial / Crown / Maestro BLDC Inverter Washing Machine & Washer-Dryer: Diagnostic fault code LC registered by the microcomputer controller. Chassis base pan anti-flood leak detection float switch triggered by standing water.

The primary root cause for Midea code LC is: On Midea appliances engineered with Lunar Dial integrated knob display, high-efficiency BLDC permanent magnet motor, Water Cube stainless drum, and digital frequency level sensor (21-26 kHz): Punctured tub door bellow gasket, split drain hose, or leaking tub seam depositing water in bottom tray Metrological tolerance verification: float microswitch continuity 0.0 Ω closed (leak state), open circuit (dry state); water volume in pan > 150 ml..

To resolve error code LC: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: disconnect power, tilt appliance backward to drain safety tray, dry floor basin, and trace leak using dry paper towels. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Turn cycle selector to Off. Press and hold 'Delay End' and 'Spin' (or 'Speed') buttons simultaneously for 5 seconds until 'T01' appears. Turn dial to 'T02' (Fault Memory), press 'Start/Pause' to display stored codes, then hold 'Start/Pause' for 3 seconds until '---' appears to clear all errors. Switch machine off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Midea code LC persists, the physical component causing On Midea appliances engineered with Lunar Dial integrated knob display, high-efficiency BLDC permanent magnet motor, Water Cube stainless drum, and digital frequency level sensor (21-26 kHz): Punctured tub door bellow gasket, split drain hose, or leaking tub seam depositing water in bottom tray Metrological tolerance verification: float microswitch continuity 0.0 Ω closed (leak state), open circuit (dry state); water volume in pan > 150 ml. 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.
