Hello! Model WMMS3330RZ is fingerprint resistant but this would not be scratch resistant. Thank you for your inquiry about our Whirlpool® appliances.

We appreciate you taking the time to share your feedback with us! We're genuinely sorry to hear that you had a negative experience with your Whirlpool® Dishwasher. Please see below for some troubleshooting tips.

Is Rinse Aid being used?
Using a rinse aid will optimize your drying and wash performance. This dishwasher is specifically designed to be used with rinse aid for improved drying performance and controlling the buildup of hard water deposits. Rinse aid greatly improves drying by allowing water to drain from the dishes after the final rinse. Rinse aid also keeps water from forming droplets that can dry as spots or streaks.
The dispenser holds 5 oz (150 mL) of rinse aid, which will, under most conditions, last 1 to 3 months. Check the indicator while the dishwasher door is fully open (level). If the rinse aid is empty, the indicator will appear clear. The color of the dispenser will depend on the color of the rinse aid you are using.
NOTE: Plastic and items with nonstick surfaces can be difficult to dry because their porous surfaces may collect water droplets. Towel drying may be necessary. https://youtu.be/LPm_ZtsGvoE
Higher numbers dispense more rinse aid. You should change this setting only a little at a time and then run a few cycles before changing it again, because just enough rinse aid is more effective than too much. https://youtu.be/-_sg60h3CGg

Was Door Open Dry selected?
Some models feature a Natural Dry technology that automatically opens the door at the end of the cycle to vent out moisture and humid air, accelerating the drying process. The "Door Open Dry" option opens the door a few inches after the washing phase is complete, improving drying performance by allowing hot air to escape and fresh air to circulate inside the dishwasher.
Press the "Door Open Dry" button on the console to enable the option, and the LED will illuminate. This option can be used with all cycles.

Were the dishes loaded correctly?
Loading items in a manner that water does not pool during the wash cycle will help with drying these items. Place glasses in the upper rack between the wire tines, not over the top of the tines; these tines can create water spots. Use the tines to angle all flat or concave surfaces as much as possible to allow water to drain off the item. Rinse Aid may help reduce puddles by allowing water to sheet off the items at shallower angles.
NOTE: Due to their complex shapes, plastic items are especially difficult to load to promote drying. Also, plastic does not conduct heat like glass or ceramics. If available, load your plastic cups, bowls, and mugs in the third-level rack for the best dry performance. Don’t put plastic items on the lower rack. Plastic items are less likely to deform when loaded in the top rack. https://youtu.be/lhEu_19sc1I

Is the water temperature set correctly?
This dishwasher has a water heating feature, but it requires a connection to a hot water supply line. The hot water supply line should supply a minimum of 120°F (49°C) water to the dishwasher for best wash and dry performance. https://youtu.be/26V_Wy7SdfI

Was a heated or dry cycle used?
Ensure a heated dry cycle and/or option is selected. Check your User's Manual for cycle details and information.
Most dishwashers will have the following dry options: air dry (no indicator light displayed or specific option), Heat or Pro Dry option for smaller loads, or Extended Dry option for large loads. The default option will be the Heat or Pro Dry option, which should provide good results. If the Heat or Pro Dry option did not dry the load as you desired, select the Extended Dry option. Using this option will extend the dry time by 15 minutes and is likely to lead to even better drying performance.
Some dishwashers have an "Open Dry" function that enables the door to automatically open after the cycle to vent out moisture/Humid Air and accelerate drying.

Is the heating element working properly?
To test the heating element, run a cycle using the Sanitize option selected. If the Sanitize LED is on steady (not blinking), there is no problem with the dishwasher's heating element. If the Sanitize cycle has completed, the dishwasher has reached its max temperature, therefore the heating element (which performs the drying function) is working properly. Today's dishwashers are more energy-efficient, and the key to optimal drying performance is proper loading and Rinse Aid.
If the Sanitize LED is blinking (not on steady), there may be a problem with the dishwasher's heating element, and service will need to be scheduled.

Don't have the Sanitize option?
To test the heating element, run a "1-hour" wash cycle and ensure the "Heat Dry" option is selected. With the "Heat Dry" option selected, the total cycle time should take about 1.5 hours. Once the cycle has finished, check to see if the dishes are warm. If the dishes are not warm, there may be a problem with the dishwasher's heating element, and service will need to be scheduled. Today's dishwashers are more energy-efficient, and the key to optimal drying performance is proper loading and the use of Rinse Aid.
