dET — Detergent Cartridge Not Detected

Whirlpool's OEM documentation states that 'dET' means the detergent dispenser cartridge is not detected — it isn't a low/empty warning telling you the reservoir needs refilling. If you're using single-load detergent doses instead of the Load & Go bulk cartridge, Whirlpool says this message can be ignored.

How to fix it

  1. If you're using single-load detergent (pods or cups) rather than the Load & Go cartridge, you can ignore this message — it doesn't affect the wash.
  2. If you use Load & Go, pull the dispenser out and confirm the cartridge is inserted and clicks fully into place.
  3. Wipe down the cartridge and the dispenser's contact points, then reseat the cartridge.
  4. If the message persists with a properly seated cartridge, the cartridge-detection sensor may need service.

Why it happens

Typical signs: 'dET' or 'Detergent' message on display · Message appears even with single-dose detergent (pods/cups) instead of the Load & Go cartridge · Load & Go cartridge missing, removed, or not fully seated

  • Load & Go cartridge not installed or not fully seated The dispenser can't detect the cartridge, so it prompts you.
  • Using single-load detergent instead of Load & Go Expected behavior — Whirlpool says you can ignore the message in this case.
  • Dirty or worn cartridge sensor contacts Residue on the cartridge or its contacts can prevent detection even with the cartridge inserted.
