We get a white film on dishes and silverware after running then dishwasher. It 's getting worse gradually over time. What is the cause and how do we correct it.
your dishes or glassware appear with a white film or a white powdery residue or spotted following a complete
wash cycle, adjusting the amount or type of detergent you?re using and
adjusting your hot water heater?s water temperature may solve the
problem. But before you do either of these, put a rinse additive (such
as Jet-Dry) in the rinse dispenser to improve the sheeting action of
Next, you?ll have to determine whether the film is
removable or permanently etched. To do this, soak a glass in undiluted
white vinegar for about 15 minutes. Or, wash the glass with warm water
and concentrated dishwasher detergent or a high-phosphate detergent
(such as Glass Magic).
If the film comes off, it is probably
caused by hard water minerals, improper amounts of detergent, or
unsuitable water temperature.
Permanent etching is often
caused by a combination of soft water and excessive heat or detergent.
If glassware is permanently etched, there isn?t anything you can do to
make it clear again. But you can avoid future etching by taking these
1) Be sure hot water entering the dishwasher is no hotter
than 140 degrees F. Don?t use extra-hot settings such as ?Power Scrub,?
and use the ?Energy Saver? dry cycle.
2) Adjust the detergent amount.
Don?t pre-rinse your dishes before loading them in the dishwasher. Food
particles on the dishes actually help the detergent and drying agents
A common cause of poor washing results is
improper loading?dishes that block or impede the spray arm(s) or
prevent the soap dispenser from opening. On the other hand, if your
dishwasher has chronic problems with good washing, the problem may not
be your dishwasher. A good first step is vary the amount of dishwasher
detergent you're using and try switching brands.
possibilities: Your home?s water pressure may be too low, your water
may be too hard, or the water temperature may not be hot enough.
order for your dishwasher to fill to the appropriate level, water
pressure should be from 20?120 pounds per square inch. If you suspect
that your water pressure may be low, turn off all faucets or other
users of water (such as washing machines and sprinklers) and then put a
half-gallon jug under the kitchen faucet. Turn on the hot water
full-blast. If the jug doesn?t fill within 14 seconds, your water
pressure may be too low for proper dishwasher operation. Call your city
water utility to discuss your options, or avoid drawing water elsewhere
in the house or yard during dishwasher cycles.
The right amount
of detergent to use depends on how large your load of dishes is and how
hard your water is. Hardness is measured in grains of minerals?the more
grains per gallon you have, the more detergent you?ll need. If your
water has 12 grains or more of hardness, fill both dishwasher soap cups
completely with detergent. If that doesn?t work, consider installing a
water softener. (For more information, see the article Water Softener
To check water temperature, hold a meat thermometer
under the hot water faucet for two minutes; if it doesn?t register a
minimum of 140 degrees F., turn up the temperature dial on your hot
water heater. (However, if you have a newer dishwasher that heats the
water internally, it isn?t necessary to turn up your hot water heater.)
your dishwasher has worked fine in the past but suddenly your dishes
aren?t clean after the dishwasher completes all cycles, listen to the
spray arm(s) spinning inside during the wash cycle. If spinning poorly,
wait for the machine to cool down, remove the spray arm(s) by
unscrewing the hubcap(s), lifting the arm(s) off, and then cleaning out
the spray holes in the spray arm(s) with a stiff piece of wire.
