Decision path

Safe checks, in order

  1. 1

    Confirm code and model scope

    Compare the complete display and full model number with the cited manufacturer page or manual before applying any troubleshooting instruction.

    Expected: The official source explicitly covers the displayed code and product family.

    If not resolved: Contact manufacturer support with the full model and serial number.

  2. 2

    Follow the official owner checks

    On the models listed below, simultaneously press and hold down the Cycle Select and Start pads for 5 seconds or until the 999 code goes away. A blank display or another number appearing is acceptable. Press ANY button to complete the reset process (130 or another cycle time may appear).

    Expected: Only the user-accessible condition identified by the official source is corrected.

    If not resolved: Stop repeated resets and arrange qualified service if the code returns or the source directs service.

Reset and test

  1. Yes (official: Cycle Select + Start for 5 seconds; see source article for model list).

Important: A reset may clear the display but cannot repair the underlying condition; follow only the exact model-specific manufacturer procedure.

Escalation point

Stop and arrange service when

  • On 'Floor Protect with Alert' models, contact service (the official article lists model numbers where the 999 is a leak alert).
