What is true of this model and changes how you fix it
- Hardware — Whirlpool product pageBoost Cycle, Triple Filtration Wash, 55 dBA, pocket-handle door style (vs. the WDT540's towel-bar handle) — same internal platform as the WDT540HAMZ, different door hardware.
- Tub & dryingThis tier often has a plastic tub base (vs the stainless of the WDT models), which retains less heat, so drying can be a bit weaker — lean on the Heat Dry option and rinse aid. Keep plastics off the tub floor if a heating element is fitted.
- WashAdjustable racks and a sensor or dial cycle. A manual filter at the tub floor must be cleaned periodically — the top cause of poor cleaning and odor.
- OptionsHigh Temperature Wash, Sani Rinse, Heated Dry and Extended Dry, which adds about 30 minutes of drying.
- Triple FiltrationCoarse, fine and micro-fine filters.
- Model labelThe WDP540HAMZ is a Whirlpool built-in dishwasher, and the label is on the right or left inside edge of the door. The model number WDP540HAMZ is followed by a series digit that Whirlpool uses to track changes.
- Cycles and optionsThe dishwasher offers Normal, Heavy and other cycles with options such as Heated Dry and Boost. Pick the cycle by the soil, not by habit. A cycle that is too light leaves residue, while Heavy uses more energy than needed.
- Installation notesA built-in dishwasher needs a water supply, a drain connection and a power supply under the sink. A loose drain hose or a kinked inlet explains many faults, so check them before replacing parts. Whirlpool's installation guide lists the connection points.
- Loading and detergentLoad the bottom rack with plates facing the center and pots facing down, and the top rack with cups and glasses angled. Use the detergent compartment for the main wash and keep it dry before loading. Detergent pods work well if the compartment door closes freely.
- Smells and filmA smell usually comes from food in the filter or the drain, and a white film on glassware from hard water. Clean the filter, run a cleaner through the machine and use rinse aid. Check the drain line for a loop or an air gap so that water from the sink cannot flow back.

Exact questions
Questions that only have an answer for the Whirlpool WDP540HAMZ dishwasher
Is the Whirlpool WDP540 worse at drying than the WDT models?+
A little — the WDP tier typically uses a plastic tub base, which holds less residual heat than the stainless tub of the WDT models, so condensation drying is slightly weaker. Compensate by turning on the Heat Dry option, keeping the rinse-aid tank filled and raised, and cracking the door open after the cycle. Plastics will still be the dampest items regardless of tub material.
