Ariston Dishwasher Error Code AL 06

Timeout filling

Ariston codesAriston dishwasher codes

Timeout filling - no turbine rotation and pressure switch contacts do not close within 1 minute 30 seconds; also covers inlet solenoid valve or drain pump electrical circuit faults.

First step from the service manual

Check that water tap is open, inlet solenoid valve is functional, solenoid valve cables are connected, and turbine is operational.

What AL 06 means on a Ariston dishwasher

AL 06 on an Ariston dishwasher signals a timeout fault during the fill cycle. Specifically, the control board monitors two conditions during water intake: the turbine (flow meter) must detect rotation as water passes through, and the pressure switch contacts must close to confirm that an adequate water level has been reached. If neither condition is satisfied within 1 minute and 30 seconds of the fill valve opening, the board triggers AL 06 and halts the cycle to prevent overflow or dry-pump operation.

The fault also covers electrical circuit faults in the inlet solenoid valve or drain pump circuits. This means AL 06 can appear not only when water physically fails to enter the machine, but also when the control board detects a wiring or connectivity problem in those circuits. A broken or disconnected cable to the solenoid valve, for example, would prevent the valve from opening at all, producing the same timeout condition as a blocked water supply.

Diagnosing AL 06 requires a systematic check of the entire fill pathway. Start by confirming the water supply tap is fully open and inlet hose is not kinked. Then inspect the inlet solenoid valve for function and verify its wiring connectors are secure. The turbine or flow meter should spin freely without debris obstruction. The pressure switch and its hose should be checked for blockages or damage. Electrical resistance checks on the solenoid valve coil can help confirm whether the component itself has failed.

Common causes of AL 06

  1. 01

    Water supply tap closed or restricted

    Wiring / connection

    If the tap feeding the dishwasher is partially or fully closed, insufficient water reaches the machine to satisfy the fill timeout. Open the tap fully and check the inlet hose for kinks or blockages.

  2. 02

    Faulty or blocked inlet solenoid valve

    Part replacement

    The solenoid valve controls water entry and can fail mechanically due to debris in the filter screen, or electrically due to a burned-out coil. A failed valve will not open regardless of water supply pressure.

  3. 03

    Disconnected or damaged solenoid valve cables

    Wiring / connection

    AL 06 explicitly covers electrical circuit faults in the inlet solenoid valve circuit. Loose, corroded, or broken wiring connectors at the solenoid valve will prevent it from receiving the signal to open.

  4. 04

    Turbine (flow meter) not rotating

    Part replacement

    The turbine must spin as water flows past it to confirm fill activity to the control board. A jammed or debris-clogged turbine will fail to register flow even if water is entering, triggering the timeout.

  5. 05

    Pressure switch not closing

    Part replacement

    The pressure switch signals the control board when the correct water level is reached. A faulty switch, blocked pressure hose, or air trap issue can prevent this confirmation, causing the board to register a fill timeout.

Frequently asked questions about AL 06

What does AL 06 mean on a Ariston dishwasher?
AL 06 indicates a fill timeout fault. The dishwasher failed to confirm water entry within 1 minute and 30 seconds, because neither the turbine rotation nor the pressure switch contact closure was detected. The code also covers electrical faults in the inlet solenoid valve or drain pump circuits. The machine stops automatically to prevent damage.
How do I fix AL 06 on my Ariston dishwasher?
Begin by confirming the water supply tap is fully open and the inlet hose is not kinked or blocked. Next, check that the cables to the inlet solenoid valve are securely connected. If the supply and wiring are confirmed good, the solenoid valve itself, the turbine flow meter, or the pressure switch may need to be tested and replaced. A technician can perform resistance and continuity checks to pinpoint the faulty component.
Is it safe to keep using my dishwasher when AL 06 appears?
No, you should not continue running the dishwasher while AL 06 is active. The machine has already halted the cycle because it could not confirm a proper fill, and running it without confirmed water intake risks damaging the wash pump. Address the underlying cause before attempting another cycle.
Will resetting the dishwasher clear the AL 06 error?
A reset may clear the error code temporarily, but it will return immediately if the underlying problem has not been resolved. The fill timeout will repeat on the next cycle if the water supply, solenoid valve, turbine, or pressure switch fault is still present. Resetting is useful only to confirm a repair was successful after the cause has been corrected.
How much does it cost to repair an AL 06 fault on an Ariston dishwasher?
Repair costs vary depending on the root cause. If the fix is simply opening a water tap or reconnecting a loose cable, there is no parts cost and minimal labor. Replacing an inlet solenoid valve or turbine flow meter typically costs between $80 and $200 including parts and labor, while pressure switch replacement tends to fall in a similar range. Diagnostic fees from a technician generally run $50 to $100 and may be applied toward the repair total.
