Parts for Whirlpool UDT518SBDP0: 03 - Tub Parts

The Affresh Dishwasher Cleaner is an OEM accessory designed specifically for Whirlpool brand dishwashers. This citrus-scented tablet removes residue, odor-causing soils, and food particles from the dishwasher tub and gasket area during the cleaning cycle. Symptoms of a buildup include unwanted odors emanating from the dishwasher, especially after opening the door. Over time, residue and grime accumulate in hard-to-reach areas and provide an environment for mold and mildew growth.

Regular cleaning helps prevent this by removing leftover soils before they harden or encourage bacterial activity. The Affresh tablet utilizes a unique blend of cleaning ingredients that target soils and biofilms through a combination of powerful scrubbing action and natural cleaning enzymes.

As the #1 recommended dishwasher cleaner brand, Affresh is also compatible for use in Maytag, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and select Kenmore dishwashers for consistent cleanliness and freshness. The package includes six tablets 4.2 ounces

This door gasket seals the oven cavity to help maintain consistent cooking temperatures and reduce heat loss. Replacing a worn gasket restores an effective seal for safer, more even baking and roasting. What it does:

• Forms a tight seal around the oven door to keep heat inside the oven cavity
• Helps prevent heat and smoke from leaking into the kitchen
• Can improve cooking performance and reduce energy loss when the original gasket is damaged
• Worn or torn gaskets may cause longer cook times, uneven baking, or hot spots around the door

• One oven door gasket

• Disconnect power to the appliance before beginning any repair
• Remove the oven door or open it per your model's service instructions to access the gasket channel
• Replace the gasket by seating it into the channel evenly; avoid stretching the gasket excessively
• If you encounter clips or fasteners, reuse only the hardware specified by the manufacturer

This replacement shield is a molded protective cover that helps keep moisture, debris, and stray materials away from internal components. It restores the barrier needed for reliable operation and helps prevent damage to nearby parts. What it does:

• Covers and protects internal components from moisture, dust, and debris
• Helps prevent shorting or corrosion that can cause intermittent electrical problems
• Restores the original fitted barrier that keeps moving parts and wiring clear
• Useful when the original shield is cracked, warped, or missing

• Disconnect power to the appliance before starting any repair
• Removal of outer panels or trim may be required
• Handle the shield carefully to avoid cracking during installation
• If fasteners or clips are damaged, replace them to ensure a secure fit

Tube nut secures the end of a supply or drain tube to its fitting, helping restore a tight connection. Replace a worn or corroded nut to reduce leaks and ensure reliable tube attachment. What it does:

• Threads onto a tube/fitting to hold the tube in place and maintain a seal.
• Replaces stripped, corroded, or damaged nuts that cause loose connections.
• Common symptom fixes: visible dripping at a connection, loose tube, or poor flow from the hose.
• Used wherever a threaded tube nut is required to fasten a hose or tube to a valve or fitting.

• Turn off power and shut off water supply before replacing the nut.
• Inspect mating threads and any ferrules or O-rings; replace damaged components for a proper seal.
• Hand-start threads to avoid cross-threading, then snug with pliers—do not overtighten.

This dishwasher tub wheel mounts to the inner side of the tub and supports the rack track as it moves. Replacing a worn wheel restores smooth glide and helps keep the rack aligned during loading and unloading.

• Supports the rack track on the tub wall
• Keeps the rack moving smoothly and aligned
• Reduces friction and noise during operation
• Failure signs: rack hard to slide, squeaking or grinding, rack tilting or coming off track, cracked/missing wheel

• Disconnect power and water supply before servicing
• Pull out the rack and remove track end caps or the rack, as needed, to access the wheel
• Remove the retaining screw/clip, install the new wheel, and verify it spins freely and seats fully
• Reassemble and test rack movement through full travel

The Stop is an OEM component specifically designed for Whirlpool dishwashers. It is located inside the tub assembly and helps secure the upper rack during washing cycles.  

Causes of a bad rack stop can include broken or cracked mounting points from years of rack impact and stress. Accumulated mineral deposits may hinder smooth sliding motion.

Symptoms of a bad stop include:

• Rattling or clanking noises coming from racks  
• Difficulty fully inserting or removing dish racks
• Racks rolling or slipping out of desired position 

The stop plays an important role in maintaining rack position throughout spray cycles for optimal cleaning coverage. Precise alignment contributes to hygienic sanitization and effective drying.

This OEM Whirlpool replacement part is compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and some Kenmore models.
