Westinghouse i44

Westinghouse error code I44 indicates: Westinghouse WDF Series / Fast 30 Wash Dishwasher: Pressure sensor zero calibration error at cycle start i44; sensor fails to establish atmospheric zero reference..

The primary root cause for Westinghouse code I44 is: On Westinghouse (Westinghouse WDF Series / Fast 30 Wash Dishwasher) models: Water remaining in tub from previous cancelled cycle, pressure sensor pipe holding hydraulic head, or drifted sensor calibration..

To resolve error code I44: Bail out all standing water from sump with a sponge. Blow gently into pressure sensor rubber hose to equalize pressure. 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 I44 persists, the physical component causing On Westinghouse (Westinghouse WDF Series / Fast 30 Wash Dishwasher) models: Water remaining in tub from previous cancelled cycle, pressure sensor pipe holding hydraulic head, or drifted sensor calibration. 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.
