Whirlpool Washer dET Error Code

dET is model-specific to washers with a dispenser cartridge. Whirlpool directs owners to make sure the cartridge is inserted correctly and the dispenser drawer is fully shut.

Applies to Whirlpool select front-load washer

What the appliance detected

Detected condition

The detergent cartridge is not detected in the dispenser.

What may contribute

Possible causes

  • The detergent cartridge may not be inserted correctly.
  • The dispenser drawer may not be completely closed.
  • The washer may be using single-load detergent doses instead of the cartridge system.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Confirm the dispenser type

    • Check the model manual to confirm whether the washer has a detergent cartridge system.
    • If using single-load doses on a model where Whirlpool says to ignore dET, do not treat the message as a failure by itself.

  2. Check the accessible dispenser

    • Open the dispenser drawer normally and confirm the cartridge is seated as the manual shows.
    • Close the dispenser drawer completely without forcing it.

  3. Watch for a returning message

    • Restart only as the model controls allow.
    • If dET remains on a cartridge-equipped model after the cartridge and drawer are seated, request service.

Actions not recommended

  • Do not disassemble the dispenser beyond owner-manual cleaning or cartridge placement.
  • Do not remove panels or access dispenser sensors or wiring.
  • Do not treat dET as a universal Whirlpool washer code.

When to stop and request service

  • dET persists on a cartridge-equipped model after the cartridge is seated and the drawer is closed.
  • The dispenser drawer, cartridge, or visible mechanism is damaged.
  • The model manual does not match the displayed message.
