Severity

Can you fix it yourself?

Yes — DIY-safe

Estimated time for safe first checks: 1–2 min — reposition items and restart.

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard — A6 is a loading indicator on drawer dishwashers.
  2. Open the dishwasher drawer fully.
  3. Look for any item that extends above the upper inner edge of the drawer — this is the maximum permissible height.
  4. Reposition tall items so they sit below the upper inner edge, angled downward if needed.
  5. Check that the spray arm below the top rack can rotate freely — spin it by hand to confirm nothing is blocking it.
  6. Close the drawer firmly and restart the cycle.

If the door warning comes back

  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • A6 appears on an empty or correctly loaded drawer with no tall items present
