What Detergent Low means

Detergent Low flashes on the display of Whirlpool front-load washers with a bulk dispenser, such as the WFW9150WW, when more detergent needs to go into that dispenser. It is a refill message, not an error. Use only high-efficiency liquid detergent in the bulk dispenser and set the concentration level correctly, because regular detergent tends to lengthen cycles and rinse poorly. Single-dose packets and powder do not belong in the dispenser at all; they go directly into the basket.

Common causes of Detergent Low

  • Bulk dispenser running low on detergent
  • Non-HE detergent used, leading to oversudsing
  • Concentration level set wrongly
  • Packets or powder placed in the dispenser
✓ One safe check you can try

1. Open the bulk dispenser and refill it with HE liquid detergent only. 2. Check that the concentration level matches your detergent. 3. Keep packets and powder out of the dispenser. 4. If you use a single-dose product, put it in the basket instead. 5. Do not use single-dose detergent and the bulk dispenser at the same time.

! Why to stop there
  • A refilled dispenser should clear the message, and if it does not, the level sensing needs testing
  • Oversudsing from the wrong detergent can look like a washer problem, and we sort out which it is
  • The price is in writing before work, and our repair carries a 30-day workmanship warranty
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Detergent LowDetergent Low questions
Is Detergent Low an error?

No. It flashes only when the bulk dispenser needs more detergent. Refill it with HE liquid detergent and the message should clear. It does not mean the washer needs repair.

Can I use powder or packets in the dispenser?

No. Single-dose packets and powder go directly into the washer basket, not the dispenser. Using them with the bulk dispenser at the same time can cause oversudsing and poor cleaning.

Why does non-HE detergent matter?

Non-HE detergent tends to lengthen cycle times and rinse poorly, and too much of any detergent can cause oversudsing. Use only HE detergent, in the amount the maker recommends, for good cleaning.
