Loading and Unloading the Dishwasher
The Whirlpool WDT730HAMZ manual stresses proper rack arrangement for optimal cleaning; check the filter is installed correctly and clean if needed.
Proper Rack Arrangement
According to the Whirlpool WDT730HAMZ manual, achieving optimal cleaning performance relies heavily on correct dish loading. Items should not block the spray arms, ensuring water reaches all surfaces.
The upper rack is designed for glasses, cups, and smaller items; face these downwards. Adjustable tines accommodate various dish sizes. The lower rack is best suited for larger, heavier items like pots, pans, and plates.
Ensure dishes are loaded so water can circulate freely. Avoid overcrowding, as this hinders cleaning effectiveness. Check that tall items don’t prevent the door from closing completely. Proper spacing is crucial for thorough washing and drying. Refer to the manual’s diagrams for visual guidance on maximizing rack space and ensuring efficient operation of your WDT730HAMZ dishwasher.
Items Suitable for Dishwashing
The Whirlpool WDT730HAMZ manual indicates a wide range of items are dishwasher-safe, contributing to convenient cleaning. Generally, durable dishes like plates, bowls, glasses, and cups are suitable, provided they are labeled “dishwasher safe” on the underside.
Most cookware, including pots and pans (excluding those with specific care instructions), can be washed. Silverware, such as forks, spoons, and knives, should be loaded handle-down in the cutlery basket. Plastic items labeled “dishwasher safe” are also acceptable, but position them on the upper rack to avoid heat damage.
However, always verify manufacturer’s recommendations. Items with delicate decorations or hand-painted designs may require handwashing to prevent fading or damage. Proper sorting ensures optimal cleaning and prolongs the lifespan of your dishware within the WDT730HAMZ.
Items to Avoid Placing in the Dishwasher
The Whirlpool WDT730HAMZ manual clearly outlines items unsuitable for dishwasher cleaning to prevent damage to both the appliance and the items themselves. Wooden utensils, cutting boards, and bowls should never be placed inside, as the heat and moisture can cause warping and cracking.
Cast iron cookware is also a no-go, as the dishwasher’s detergents will strip away the seasoning. Hand-blown glass, crystal, and delicate china are prone to breakage and should be handwashed. Aluminum cookware can discolor and lose its shine.
Furthermore, items with glued parts, such as handles, may separate. Non-stick cookware’s coating can degrade over time with repeated dishwasher use. Adhering to these guidelines, as detailed in the manual, ensures longevity and prevents potential issues.
Maintenance and Cleaning
The Whirlpool WDT730HAMZ manual stresses regular filter cleaning, spray arm maintenance, and exterior wiping for optimal performance and longevity of your dishwasher.
Filter Cleaning Instructions
According to the Whirlpool WDT730HAMZ manual, maintaining a clean filter is crucial for optimal dishwasher performance. Regularly check the filter to ensure it’s properly installed and free from debris. If needed, remove the filter – typically located at the bottom of the dishwasher tub – and rinse it thoroughly under running water.
The manual details a multi-step process: first, rotate the filter to unlock it, then lift it out. Remove any food particles or residue. For stubborn buildup, a soft brush can be used. Ensure all mesh screens are clear. Reinstall the filter by aligning the arrows and rotating to lock it into place. A properly functioning filter prevents redeposit of food particles and ensures efficient draining, contributing to sparkling clean dishes.
Ignoring filter maintenance can lead to poor cleaning performance and potential blockages, so consistent cleaning is highly recommended.
Spray Arm Maintenance
The Whirlpool WDT730HAMZ manual emphasizes the importance of maintaining clean spray arms for effective dishwashing. Over time, food particles can clog the spray arm nozzles, reducing water pressure and cleaning performance. To address this, periodically inspect the spray arms – both upper and lower – for any visible obstructions.
The manual instructs users to remove the spray arms (usually by unscrewing or unclipping) and carefully clear any debris from the nozzles using a toothpick or small wire. Ensure the nozzles are fully open and unobstructed. Rinse the spray arms thoroughly under running water to remove any dislodged particles. Reattach the spray arms securely, verifying they rotate freely.
Regular spray arm maintenance ensures optimal water distribution and prevents food residue from being redistributed onto clean dishes, contributing to consistently sparkling results.
Exterior Cleaning Recommendations
The Whirlpool WDT730HAMZ manual advises using mild dish soap and warm water for cleaning the dishwasher’s exterior surfaces. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish, particularly on stainless steel models. For fingerprint-resistant stainless steel, a specialized stainless steel cleaner is recommended to maintain its appearance and minimize smudges.
To clean, dampen a soft cloth with the soapy water solution and gently wipe down the door, sides, and control panel. Rinse with a clean, damp cloth and dry thoroughly to prevent water spots. Pay attention to the handle area, as it accumulates fingerprints. For stubborn stains, allow the soapy water to sit for a few minutes before wiping.
Regular exterior cleaning keeps your Whirlpool dishwasher looking its best and protects its finish for long-lasting beauty.

Troubleshooting Common Issues
