Hoover AL05

Hoover error code AL05 indicates: Hoover H-DISH 300 / 500 / 700 Maxi Tub Smart Dishwasher: Water filling timeout alarm AL05; wash tank does not fill to operating level within program timeout limit..

The primary root cause for Hoover code AL05 is: On Hoover dishwashers utilizing H-DISH Maxi Tub architecture, Triple Self-Cleaning micro-filtration wash system, and hOn Wi-Fi connectivity: 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). Hold the Programme selector button and Start/Pause together for 6 seconds until all indicator LEDs light up, then power off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hoover code AL05 persists, the physical component causing On Hoover dishwashers utilizing H-DISH Maxi Tub architecture, Triple Self-Cleaning micro-filtration wash system, and hOn Wi-Fi connectivity: 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.
