Whirlpool TUD4700 用户手册

■

Sometimes there is a water/chemical reaction with certain 
types of glassware. This is usually caused by some 
combination of soft or softened water, alkaline washing 
solutions, insufficient rinsing, overloading the dishwasher, 
and the heat of drying. It might not be possible to avoid the 
problem, except by hand washing. 

To slow this process use a minimum amount of detergent but 
not less than 1 tb (15 g) per load. Use a liquid rinse aid and 
underload the dishwasher to allow thorough rinsing. Silica 
film and etching are permanent and cannot be removed. Do 
not use heated drying.

■

Has the dishwasher detergent removed cookware 
seasoning? Reseason cookware after washing in the 
dishwasher.

■

Does your water have high iron content? Rewash dishes 
using 1-3 tsp (5-15 mL) of citric acid crystals added to the 
covered section of the detergent dispenser. Do not use 
detergent. Follow with a normal wash cycle with detergent. If 
treatment is needed more often than every other month, the 
installation of an iron removal unit is recommended.

■

Are aluminum items rubbing dishes during washing? 
Disposable aluminum items can break down in the 
dishwasher and cause marking. Hand wash these items. 
Remove aluminum markings by using a mild abrasive cleaner.

■

Are large amounts of tomato-based foods on dishes placed 
in the dishwasher? Stains can gradually fade over time. 
Regular use of heated drying will slow fading. Stains will not 
affect dishwasher performance. Regular use of a rinse cycle 
and an air-dry or energy-saving dry option will reduce the 
likelihood of staining.

■

Did you load your dishwasher to allow proper water 
drainage? Do not overload. Refer to the “Dishwasher 
Loading” section. Use a liquid rinse aid to speed drying.

Are the plastics wet? Plastics often need towel drying.

Is the rinse aid dispenser empty? Refer to the “Rinse Aid 
Dispenser” section.

Did you use an air-dry or energy-saving dry option? Use a 
heated drying option for dryer dishes.

■

Did you load the dishwasher properly? Load the dishes and 
glasses so they are stable and do not strike together from 
washing action. Minimize chipping by moving the rack in and 
out slowly. 

NOTE: Antiques, feather-edged crystal, and similar types of 
china and glassware might be too delicate for automatic 
dishwashing. Wash by hand.

■

A hard object has entered the wash module (on some 
models). When the object is ground up, the sound should 
stop. If the noise persists after a complete cycle, call for 
service.
