What Does Error AL5 Mean?

The Zanussi dishwasher AL5 error indicates a water inlet or filling fault, preventing the dishwasher from filling with water. Typical symptoms include a flashing warning light or beep at startup, along with the inability to start the cycle due to a lack of water. Common causes include a closed water supply tap, low water pressure, or a kinked inlet hose. Address these issues first to resolve the error.

Common Symptoms:

  • Dishwasher does not fill with water
  • Warning light flashes once or beeps once at start
  • Cycle won’t start because no water enters

Possible Causes

  • Water supply interruption (tap closed or no home water flow) (high)
  • Low water pressure or multiple appliances drawing water simultaneously (medium)
  • Kinked, twisted, or damaged inlet hose / blocked inlet filter (high)
  • Faulty water inlet valve (less common) (medium)

How to Fix Error AL5

DIY Fix Check basic water supply and inlet components

  1. Ensure the household water supply is active and water pressure is adequate.
  2. Confirm the water supply tap to the dishwasher is fully open.
  3. Check the inlet hose for kinks, twists, or visible damage.
  4. Turn off water and power, then remove and clean the inlet hose filter next to the tap.
  5. Reconnect everything and restart the dishwasher to test if water fills.
  6. Avoid running other major water appliances concurrently to ensure sufficient pressure.

Technician Only Inspect and repair internal water inlet components

  1. Verify correct operation of water inlet valve (electromechanical valve) with multimeter and flow tests.
  2. Inspect internal water inlet assembly and pressure sensors for faults.
  3. Replace faulty inlet valve or pressure sensor as needed per model specifications.
  4. Check dishwasher control logic for water fill detection if inlet components are functioning.
  5. Test dishwasher filling operation after repairs.

Parts needed: Water inlet valve, Inlet hose and filter, Pressure/flow sensor

🛑 When to Call a Pro:
  • After user‑level checks if dishwasher still does not fill and AL5 persists
  • If inlet hose is damaged or internal components (valve/sensor) are suspected faulty
  • If water leaks or other unrelated error codes also appear
