Westinghouse E21

Westinghouse error code E21 indicates: Westinghouse EasyCare / Front Loader Washer Series: Draining timeout E21; water level fails to drop below empty threshold frequency within 90 seconds of pump activation..

The primary root cause for Westinghouse code E21 is: On Westinghouse (Westinghouse EasyCare / Front Loader Washer Series) models: Clogged domestic wall siphon, blocked sump hose eco-ball valve, worn pump magnetic impeller slipping under head pressure, or blocked pressure air trap..

To resolve error code E21: Disconnect drain hose from wall siphon and discharge into bucket to test flow. Disassemble black sump hose to verify eco-ball movement. Press Start/Pause together with Temp button for 5 seconds to exit service diagnostic mode and clear persistent EEPROM alarm.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Westinghouse code E21 persists, the physical component causing On Westinghouse (Westinghouse EasyCare / Front Loader Washer Series) models: Clogged domestic wall siphon, blocked sump hose eco-ball valve, worn pump magnetic impeller slipping under head pressure, or blocked pressure air trap. 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.
