Make sure dishes and glassware are
loaded so spray reaches all surfaces
and items drain properly. Do not
overload. Do not nest items.
Make sure large items do not block
spray from reaching detergent
dispensers.
Check spray arms to make sure they
turn freely after loading. Be sure a
utensil has not prevented their
turning.
Use more dishwasher detergent. Use
detergent with highest available
phosphorous content...especially with
hard water.
Use only fresh dishwasher detergent.
Store tightly closed container in cool,
dry place. Discard old detergent. Do
not fill dispensers until ready to start
dishwasher.
If water pressure is low, do not use
water for other purposes while
dishwasher is running (to assure
correct fills).
Check for rainbow hue on glasses. A
rainbow hue is the first sign of etching
(corrosion of glass). Reduce the
amount of dishwasher detergent. Use
a detergent with a lower phosphorous
content.
If water pressure is low do not use
water for other purposes while
dishwasher is running (to assure
correct water fills). Make sure dishes
and glassware are loaded properly to
assure adequate rinsing and draining.
Do not overload.
Temporary remedy:
1. Set empty dishwasher for a “one
wash” cycle.
2. Start dishwasher and unlatch door
to stop it when it has filled for the
wash part of the cycle.
3. Add l/4 to l/2 cup (120 to 240 mL)
of citric acid crystals (usually
available in drugstores).
4. Close and latch door to complete
cycle.
Permanent solution:
Install an iron or
manganese filter to home water
supply.
