Quick answer

Leak or overflow detection codes usually point to a shared symptom category, not one guaranteed failed part. Start with visible conditions, then use the matching brand code page below.

What this problem type covers

This hub groups matching appliance code pages for Dishwasher. Covered brands include GE Appliances, LG, Samsung, KitchenAid, Bosch. It is useful when searches mention a symptom, such as drain code, fill error, leak warning, or airflow restriction.

Exact steps still depend on brand and model number. Use the code page for the display text on your appliance before opening panels or ordering parts.

Common causes

  • Leak pan or base sensor is wet
  • Oversudsing
  • Loose hose or drain connection
  • Stuck inlet valve
  • Door gasket or tub seal leak

Safe first checks

  1. Turn off the water supply if water is actively leaking.
  2. Disconnect power if water is near an outlet, cord, or control area.
  3. Look for obvious hose, door, or drain leaks without tipping the unit.
  4. Let the base dry only after the source of water is understood.
  5. Move to the exact brand code page if the same warning returns.

Stop troubleshooting when

  • Water is under the appliance.
  • The code returns after drying.
  • The appliance fills when turned off.
