  1. Confirm PE on the exact model

    Reversible

    Photograph the complete display, record the model tag and note the cycle stage. Similar-looking codes can mean different things on another product line.

  2. Check the condition named by the code

    Reversible

    Record whether the tub is empty, normally filled or overfilled before changing anything.

  3. Correct the remaining user-serviceable cause

    Reversible

    Power the washer off briefly and inspect only external hose and drain installation.

  4. Run one controlled verification

    Retry one empty cycle and stop if the displayed level does not match the actual water. The sensor and internal pressure tube are service components; do not open the cabinet.
