AEG i44

AEG error code I44 indicates: AEG Favorit / ProClean / ComfortLift Series: Pressure sensor zero calibration error at cycle start i44; sensor fails to establish atmospheric zero reference..

The primary root cause for AEG code I44 is: On AEG (AEG Favorit / ProClean / ComfortLift Series) 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. Rotate selector to 12 o'clock (OFF), press and hold Start/Pause and Exit simultaneously for 4 seconds until the diagnostic LED sequence resets error memory.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if AEG code I44 persists, the physical component causing On AEG (AEG Favorit / ProClean / ComfortLift Series) 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.
