Common Dishwashing Problems
PROBLEM
CAUSED BY
SOLUTION
Spotting and filming
Hard water
Fill detergent dispensers to capacity.
Use dishwasher detergent with highest
available phosphorus content. May be
necessary to install water softener.
To remove spots and film, try a vinegar
rinse
1.
Wash and rinse load as usual. Dry
without heat.
2. Remove all metal items.
3. Put 2 cups (500 mL) white vinegar in
a container on the bottom rack.
4. Run dishwasher through a complete
washing cycle.
Water is not hot enough
Water temperature should be at least
140°F (60°C). Set water heater
thermostat to a higher setting. Run
water at sink until hot before starting.
Not enough detergent, or improper
detergent
Use more dishwasher detergent. Use
detergent with highest available
phosphorus content especially with
hard water.
“Old” detergent 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.
Improper loading
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.
No rinse agent
Does the rinse agent dispenser need
filling? See instructions on page 7.
Drying without heat
Drying without heat may result in some
spotting of glasses and silver. Dry with
heat.
Small particles deposited on items Spray arm not rotating freely
Check spray arm to make sure it turns
freely after loading. Be sure a utensil
has not prevented it from turning.
