AEG i43

AEG error code I43 indicates: AEG Favorit / ProClean / ComfortLift Series: Dynamic water level fluctuations alarm i43; abnormal pressure oscillations detected during circulation..

The primary root cause for AEG code I43 is: On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Spray arms jammed against tall plates or cutlery, lower spray arm clogged with lemon seeds, or foaming from rinse aid overfill..

To resolve error code I43: Ensure upper and lower spray arms rotate freely by hand. Clean clogged spray arm nozzle orifices with a needle. Check for excessive foam. 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 I43 persists, the physical component causing On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Spray arms jammed against tall plates or cutlery, lower spray arm clogged with lemon seeds, or foaming from rinse aid overfill. 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.
