Maytag Dishwasher MDB6702AWS41 Not cleaning dishes properly

The Pump Filter is an OEM part for Whirlpool dishwashers. This part is strategically designed to trap and filter out food particles, debris, and other substances that could clog the dishwasher's pump and drainage system.

A bad Pump Filter can result from debris buildup, wear and tear, and structural damage. This can hinder water flow, reduce cleaning efficiency, and compromise particle trapping ability.

Symptoms of a malfunctioning Pump Filter include:

• Poor cleaning results, as clogged filters can impede water flow and reduce the dishwasher's effectiveness.
• Water not draining properly, potentially leading to water pooling at the bottom of the dishwasher.
• Unusual noises from the dishwasher, which can indicate that the pump is working harder than normal to circulate water through a clogged filter.

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

Located on the supply tube behind the upper dishwasher rack.

This dishwasher wash impeller mounts on the circulation pump to drive water through the spray arms. A worn or damaged impeller can cause weak spray, poor cleaning, or noise; replacing it restores proper wash pressure. What it does:

• Moves water from the circulation pump through the filter and spray arms for effective cleaning
• Maintains proper wash pressure and spray action during the cycle
• Common fix for poor cleaning, spray arms not turning, or weak/no water circulation
• May reduce grinding or rumbling noises caused by broken or stripped impeller blades

• Includes 1 wash impeller

• Disconnect electrical power and shut off the water supply before servicing
• Remove the lower rack and spray arm; take off filters/sump cover to access the impeller
• Note impeller orientation; transfer any spacers as found and secure the impeller without overtightening
• Reassemble, check for leaks, and verify spray arm rotation after a test cycle

Color white. The wash arm measures about 11 inches, and the retainer about 3 inches.

This upper wash arm directs rotating spray to the dishwasher's top rack to help improve cleaning coverage and reduce food/residue on upper-rack dishes. Fits as the rotating upper spray arm assembly for compatible dishwashers. What it does:

• Rotates and sprays water across the upper rack to help remove stuck-on food and rinse dishes.
• Helps correct weak or uneven spray patterns from the top rack.
• Can reduce spotting and areas that remain soiled when the upper arm is damaged or clogged.
• Replaces a worn, cracked, or clogged upper spray arm to restore proper spray action.

• Always disconnect power to the dishwasher and turn off the water supply before servicing.
• Remove the upper rack to access the arm; unclip or unscrew the old arm and install the replacement until it seats/threads securely.
• Clear any debris from the mounting area and ensure the arm spins freely before running a test cycle.
• Run a short rinse or quick cycle to verify correct spray pattern and fit.

This heater warms the wash water inside the tub during selected cycles. Replacing a failed element restores proper water temperatures, supporting cleaning performance and preventing extended run times or incomplete cycles. What it does:

• Heats water in the washer tub during hot/sanitize/temperature-controlled cycles
• Helps maintain target temperature for effective cleaning and stain removal
• Common symptoms include water not heating, cycles taking unusually long, or cycles stopping early
• Accompany control errors related to water temperature or the heater circuit

• 1 heater

• Disconnect power and shut off water supplies before servicing
• Access is typically from the rear or bottom; be prepared for residual water when removing the old element
• Clean sealing surfaces and seat the element fully; tighten fasteners evenly to prevent leaks
• After installation, run a hot cycle to check for leaks and heating

Lower wash arm redirects pressurized water across the dishwasher's lower rack to rinse and remove food and residue, restoring intended wash coverage and improving cleaning performance. What it does:

• Directs jets of water through multiple spray holes to rinse dishes on the lower rack.
• Helps remove stuck-on food, film and spotting on plates, bowls and cookware.
• Replaces cracked, clogged or broken lower spray arms that can cause poor cleaning or leftover residue.
• Works with the dishwasher's pump flow to maintain proper spray pattern across the lower rack.

• Refer to your model's parts diagram and instructions; the arm commonly snaps or threads onto the lower spray arm mount and procedures vary by model.
• Always disconnect power to the dishwasher before servicing; follow basic safety precautions.
• Clean the filter and any debris from spray holes before installing to avoid re-clogging.
• Inspect the mounting clip or retaining nut when removing the old arm and replace if damaged.

This wash arm cap secures the dishwasher spray arm to its hub so it spins freely and distributes water. Replace a worn or missing cap to restore wash performance and keep the spray arm from loosening or coming off.

• Locks the spray arm onto its post/hub for proper alignment
• Allows smooth rotation for even water spray coverage
• Helps prevent wobbling, noise, or the arm detaching during cycles
• Common signs: spray arm falls off, is loose, doesn't spin, or dishes aren't getting clean

• Disconnect power; open the door and remove the rack to access the spray arm
• Unscrew and remove the old cap; lift off the spray arm if needed
• Seat the spray arm and hand-thread the new cap; tighten snugly without over-tightening
• Spin the spray arm by hand to ensure free movement before running a cycle

This top wash arm retainer secures the dishwasher's upper spray arm so it spins freely and stays aligned, helping maintain proper water distribution for upper-rack cleaning. Replace a cracked or worn retainer to reduce wobble and misalignment. What it does:

• Holds the upper/ top spray arm in place on the spray assembly so the arm can rotate correctly.
• Prevents the spray arm from slipping or wobbling during the wash cycle.
• Helps restore proper water spray coverage to the upper rack when the original retainer is broken or worn.
• Compatible with standard upper spray arm mounting—no modification required.

• Includes: 1 top wash arm retainer

• Disconnect power to the appliance before beginning any repair.
• You may need to remove the upper rack and/or the spray arm to access the retainer; keep parts organized for reassembly.
• Inspect the spray arm and attachment for damage or debris while replacing the retainer.
• Use hand tools only.
