Hotpoint Dishwasher Error Code AL06

Fill water timeout

Hotpoint codesHotpoint dishwasher codes

Fill water timeout - The time allowed for water to fill and for the pressure switch to reach FULL (set seconds) has been exceeded.

First step from the service manual

Check turbine connector for disconnection; check turbine cables for damage; check Main PCB/water meter turbine; check if turbine is faulty or wet; check if more than 1 litre of water has been filled manually to the tub.

What AL06 means on a Hotpoint dishwasher

The AL06 error code on a Hotpoint dishwasher indicates a fill water timeout fault. During the fill phase of a wash cycle, the control board allows a set number of seconds for water to enter the tub and for the pressure switch to register a FULL level. When that time limit is exceeded without the pressure switch confirming adequate water volume, the machine halts and displays AL06. This is a protective timeout designed to prevent overfilling, underfilling, or running dry.

The water metering system in these dishwashers relies on a turbine-based flow meter rather than a simple timed fill. Water passing through the inlet circuit spins the turbine, and the pulses generated are counted by the main PCB to track how much water has entered the tub. If the turbine connector is disconnected, the cables are damaged, or the turbine itself is faulty or wet, the PCB receives no pulse data and cannot confirm that sufficient water has filled the machine. This causes the timeout to trigger even if water is physically entering the tub.

Additional causes can include problems with the water supply itself, such as low inlet pressure, a kinked fill hose, or a blocked inlet valve filter. It is also worth checking whether more than 1 litre of water has been manually added to the tub before the cycle started, as this can interfere with the turbine meter calibration and confuse the fill logic on the main PCB.

Common causes of AL06

  1. 01

    Turbine connector disconnected or damaged cables

    Wiring / connection

    The turbine flow meter relies on a secure electrical connection to the main PCB. A loose or disconnected connector, or damaged wiring in the turbine cable harness, will prevent flow data from reaching the board, triggering the fill timeout.

  2. 02

    Faulty or wet turbine

    Part replacement

    If the turbine itself has failed or moisture has entered the turbine housing, it may stop spinning or generating pulses correctly. Inspect the turbine for physical damage, debris obstruction, or signs of water ingress.

  3. 03

    Manual water addition to the tub

    Wiring / connection

    Adding more than 1 litre of water manually to the tub before starting a cycle can interfere with the turbine meter baseline, causing the fill logic on the PCB to miscalculate and time out before the correct level is reached.

  4. 04

    Restricted water inlet supply

    Wiring / connection

    Low household water pressure, a kinked or blocked fill hose, or a clogged inlet valve filter screen can reduce flow enough that the tub takes longer to fill than the PCB timeout allows. Check that the supply tap is fully open and inspect the inlet filter.

  5. 05

    Faulty main PCB

    Part replacement

    If the turbine and all wiring check out correctly, the main PCB may not be processing the turbine pulse signals properly. This is the least common cause and should only be considered after all other components have been ruled out.

Frequently asked questions about AL06

What does AL06 mean on a Hotpoint dishwasher?
AL06 indicates a fill water timeout fault. The dishwasher was unable to reach the required water level within the allowed time, so the cycle was stopped automatically. This is typically related to the turbine flow meter, its electrical connections, or the water supply to the machine.
Can I fix AL06 on a Hotpoint dishwasher myself?
Some causes are accessible to a confident DIYer. Start by checking that the turbine connector is securely plugged in and that the turbine cables show no visible damage. Also verify the water supply is fully on and the inlet hose is not kinked. If the turbine itself needs replacing or the fault points to the main PCB, a qualified appliance technician should carry out the repair.
Will resetting the dishwasher clear the AL06 error?
A reset may clear the error temporarily, but if the underlying fault is still present the code will return as soon as the machine attempts the fill phase again. Resetting without diagnosing the root cause is not a reliable fix. The turbine, its connections, and the water supply should all be checked before assuming the fault has resolved.
Is it safe to use my Hotpoint dishwasher when AL06 is showing?
The dishwasher will not complete a wash cycle while AL06 is active, so there is no immediate safety hazard from using it. However, running the machine repeatedly in a fault state is not recommended. Until the cause is identified and corrected, the machine may not fill correctly and dishes will not be cleaned properly.
How much does it cost to repair a Hotpoint dishwasher showing AL06?
Repair costs vary depending on the cause. If the fix involves reconnecting a loose turbine connector or clearing a blocked inlet filter, the cost may only be a call-out fee, typically in the range of $60 to $120. Replacing a faulty turbine flow meter generally costs $80 to $180 including parts and labour. A main PCB replacement is the most expensive outcome, often ranging from $150 to $350 or more depending on parts availability and labour rates.
