SUGGESTED REMEDY
Check that the water valve is fully
open. Make sure that the water
pressure is between 18 and 176psi.
Load dishes to prevent water and
detergent from being trapped in or
between items. Water should
circulate freely.
Temporary solution: Pour 1
teaspoon to 1 tablespoon of citric
acid crystals in instead of the pre-
wash detergent directly on the
inside of the door. Follow this per-
wash with a full detergent wash.
Use the pots/pans or normal wash
cycle. Permanent solution: install
an iron removal system in the
water supply.

Remove stains be hand, using a
solution of ½ cup bleach and 3
cups warm water. (Do not use on
