Possible Causes

Detergent and fabric softener residue in tub and hoses, Standing water in door boot folds, Infrequent hot washes, Clogged drain or vent passages

How to Fix / Troubleshooting

Safety first: Unplug the washer before cleaning internal areas. Use gloves and ventilation when using cleaners.

  • Clean door boot: Wipe the Insignia door gasket folds with a cloth and a mixture of hot water and mild bleach or washer cleaner to remove slime and mold.
  • Run cleaning cycle: Use the washer's tub clean cycle (if available) with a commercial washer cleaner or 1 cup of bleach (no laundry).
  • Leave door open: After each use, leave the door slightly open to allow the interior to dry and reduce odor formation.
  • Clean dispenser drawer: Remove and wash the detergent drawer and housing to remove buildup.
  • Check drain path: Ensure the drain filter and hose are clear so water fully evacuates after cycles.
