Parts for Maytag MCD4100AWE: Pump And Motor 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

The Lower Washarm is an OEM replacement part for Whirlpool dishwashers. Positioned at the bottom of the dishwasher tub, it rotates during the wash cycle, distributing water and detergent evenly across the lower rack. 

Over time, wash arms can become clogged with food debris or mineral deposits, reducing water flow. Physical damage such as cracks or warping can also impede the wash arm's rotation and affect its cleaning performance.

Color: Gray

Symptoms of a faulty lower wash arm include:

• Inadequate cleaning of dishes on the lower rack
• Uneven or inconsistent water spray
• Clogged or obstructed spray nozzles
• The arm not spinning or rotating correctly

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

The Pump Filter is an OEM part for Whirlpool dishwashers. This filter traps debris and prevents it from entering the pump, thereby protecting the pump and ensuring the efficient operation of the dishwasher.

Causes of a bad pump filter can include clogging due to food particles and debris, wear and tear over time, or physical damage from sharp objects or improper cleaning.

Symptoms of a bad pump filter include:

• Poor drainage or standing water in the dishwasher
• Unusual noises during the wash cycle
• Reduced cleaning performance
• Frequent clogging or blockages

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

Includes: Upper and lower impellers, impeller screw with o-ring, motor shaft seal with install tool, and 3 o-rings needed to repair pump.

Dishwasher lower washarm drain pump housing.

This O-ring seal fits into a groove to create a tight, leak-resistant barrier where two parts join. Replacing a worn O-ring helps stop drips at connections and keeps your appliance running reliably. What it does:

• Forms a compressible seal between mating parts (fittings, housings, or tubing)
• Helps prevent water or fluid leaks at joints
• Maintains proper pressure and flow within the sealed path
• Replace if you see seepage at the connection or the ring is cracked, flattened, brittle, or swollen

• 1 O-ring seal

• Disconnect power and shut off water supply before servicing
• Clean the groove and mating surfaces; remove debris that could compromise the seal
• Lightly lubricate with manufacturer-approved silicone grease; avoid petroleum-based products
• Seat the O-ring without twisting; reassemble carefully and check for leaks after testing

This impeller assembly replaces a worn or damaged wash-pump impeller to help restore water circulation and spray pressure for better cleaning. Commonly used in compatible Whirlpool wash pumps to address weak wash performance. What it does:

• Spins inside the wash pump to move water through spray arms; damaged fins reduce spray force and cleaning.
• Restores proper flow during wash cycles — symptoms of failure include weak or uneven cleaning.
• Reduces abnormal pump noise and motor strain when the impeller is intact; cracked or missing fins can cause humming or grinding.
• Works with the pump housing and seals to route water; a failed impeller can allow internal leakage or cavitation.

• Always disconnect power (and water, if applicable) before servicing the appliance.
• Inspect pump seals, gaskets, and surrounding components; replace any damaged parts to prevent leaks.

This dishwasher impeller assembly mounts on the circulation pump and pressurizes wash water for the spray arms. Replacing a worn or damaged impeller restores proper spray pressure, cleaning performance, and quieter operation.

• Spins with the circulation motor to pressurize wash water
• Drives flow to the spray arms for effective wash action
• Typical symptoms: weak or no spray, poor cleaning results, grinding or rattling from pump area
• Often fails from broken vanes or debris; inspect filters/chopper while open

• Disconnect power and water before servicing
• Access is typically from inside the tub: remove the lower spray arm, filter screens, and cover to reach the impeller
• Note the order of parts and transfer any reusable hardware; replace worn O-rings/seals as needed
• Do not overtighten plastic parts; verify the impeller spins freely before reassembly and testing

This flexible drain hose routes wastewater from the appliance to the household drain so your appliance can empty properly. Durable, service-ready replacement that restores proper draining and helps prevent backups. What it does

• Carries wastewater from the appliance pump to the household drain line.
• Restores drainage when the original hose is cracked, clogged, kinked, or leaking.
• Helps eliminate standing water, slow drains, and related error codes tied to poor drainage.
• Works with standard hose clamps and common drain fittings used on compatible appliances.

• Always disconnect power to the appliance and turn off water supply before servicing.
• Inspect hose routing and clamps; replace clamps if corroded or damaged.
• Avoid sharp bends and kinks when routing the hose; secure with clamps or ties as needed.
• After installation, run a short drain cycle and inspect for leaks before returning the appliance to regular use.

This hose clamp secures a hose connection to prevent leaks and keep your appliance running smoothly. It provides a tight, reliable hold on the hose fitting so water or air stays contained during operation.

• Tightens around a hose and fitting to maintain a secure seal
• Helps stop drips, seepage, or loose connections
• Common fix when you see moisture around a hose joint
• Useful if a clamp is rusted, stretched, or no longer holding tension

• Unplug power and shut off water (if applicable) before servicing
• Note clamp position/orientation before removal
• Use appropriate screwdriver or nut driver to tighten evenly
• Do not overtighten—ensure a snug, leak-free seal without damaging the hose

Upper wash arm retaining clip.

This snap-in outlet connector secures wiring to an appliance control or harness and restores a reliable electrical contact. Designed for a direct, tool-assisted snap fit, it helps eliminate loose or intermittent connections. What it does:

• Provides a secure snap-in electrical connection between wiring and the appliance harness or control
• Restores power flow when a worn or damaged outlet causes intermittent operation or no power
• Prevents arcing and poor contact that can result from loose terminals
• Matches OEM fit for straightforward replacement when the original snap outlet is broken or missing

• Disconnect power to the appliance before inspecting or replacing electrical parts
• Remove access panels as required to reach the outlet; replacement typically snaps into place
• Verify correct orientation and full seating of the connector to ensure a solid contact
• If corrosion or wiring damage is present, replace or repair wiring per OEM guidance
