Haier AL05

Haier error code AL05 indicates: Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Water filling timeout alarm AL05; wash tank does not fill to operating level within program timeout limit..

The primary root cause for Haier code AL05 is: On Haier dishwashers utilizing I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Scaled water supply tap, blocked metal strainer mesh in inlet hose connector, or defective inlet valve (~3.5–4.5 kΩ)..

To resolve error code AL05: Check faucet flow rate with bucket test. Remove supply hose and rinse out particulate debris from inlet filter. Measure valve solenoid (~3.5–4.5 kΩ). Press Power button off, hold Half Load and Start buttons together while powering on until diagnostic test mode 01 displays, then power off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code AL05 persists, the physical component causing On Haier dishwashers utilizing I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Scaled water supply tap, blocked metal strainer mesh in inlet hose connector, or defective inlet valve (~3.5–4.5 kΩ). 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.
