Common failure areas on this model

The confirmed parts above group into a handful of failure areas. Here is what each points to and how to check it before you order anything.

Dishrack hardware (rollers, wheels and tines)

Symptom: A dish rack that binds, drags, or comes off its rail track when you pull it in or out, or a rack with a cracked, loose, or missing wheel or tine.

Check: Pull the rack fully out and check each wheel or roller for a crack or a missing axle pin, and check that tines aren't snapped off or pushed out of alignment along the row.

Parts in this group on CDB3100AWE: WPY912545 (Dishrack Track), W10139223 (Lower Dishrack with Wheels), WP99002342 (Tub Wheel), WP903093 (White Dishrack Roller).

Water inlet and drainage

Symptom: The dishwasher won't fill, or dishes come out with standing water still in the tub bottom after the cycle ends.

Check: Check the inlet valve's screen filter for sediment, and check the drain pump and drain hose for a clog or a jammed object -- a piece of broken glass or a bottle cap is a common culprit.

Parts in this group on CDB3100AWE: WP99001782 (Dishwasher Drain Hose), WP99001359 (Water Inlet Valve - 120V), 99001359 (Dishwasher Water Inlet Valve).

Door, lid switches and latches

Symptom: The dishwasher won't start, or stops mid-cycle, unless the door is fully latched shut.

Check: Listen for an audible click when the door latches. No click, or a visibly worn or broken latch or strike, points to this part.

Parts in this group on CDB3100AWE: WP99001553 (Dispenser Door Latch Grommet), WP99001288 (Dispenser Door Switch Retainer), WP99002207 (Door Switch).

Storage, trim and cosmetic hardware

Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.

Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.

Parts in this group on CDB3100AWE: WPW10116816 (Dispenser Latch Spring), WP912653 (Door Spring Linkage), WP6912678 (Hinge Pin), WP910654 (Impeller Screw), WP99002085 (Latch Handle), WP99002136 (Rack Stop - White), 912619 (Single Steel Screw).

Door and drum seals

Symptom: Water leaking out from around the door during or after a cycle.

Check: Check the door gasket for tears, flattening, or a section pulled loose from its channel, and confirm it seats evenly all the way around when the door is closed.

Parts in this group on CDB3100AWE: WP902894 (Door Gasket).

Controls, timers and wiring

Symptom: A cycle that stops partway through, an error code or blinking light, or the unit not starting at all.

Check: Look for burn marks or a burnt smell near the board or terminals, and check whether buttons and knobs respond -- a unit that powers on but won't cycle often traces back to this group.

Parts in this group on CDB3100AWE: WP99002363 (Float Assembly), WP911265 (Float Palnut), 99002363 (Float).

Heat control (thermostats, fuses, heating element)

Symptom: Dishes don't dry at the end of the cycle, or a heated-dry setting doesn't seem to do anything.

Check: With the dishwasher unplugged, check continuity across the heating element or thermostat with a multimeter -- no continuity means it has failed.

Parts in this group on CDB3100AWE: WP99002360 (Heating Element).

General hardware and mounting parts

Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.

Check: Compare the physical shape and mounting points to the original piece, and confirm the exact part number against your model plate before ordering.

Parts in this group on CDB3100AWE: WP99002069 (Impeller Assembly), WP910934 (O-Ring Seal), WPY912679 (Short Dispenser Door Retaining Pin), WP99001576 (Silverware Basket), WP99002240 (Switch Holder), WP902899 (Wax Motor for Detergent Cup Actuation), 99002240 (Holder Switch), 910069 (Tub Washer), 903233 (Foam Seal), 99002560 (Water Switch (White)), 902899 (Wax Motor).

Filtration and spray system

Symptom: Dishes come out with food residue, spots, or a cloudy film, or you notice leftover debris in the tub bottom after a cycle.

Check: Remove and rinse the filter assembly under the tub, and check that the spray arm spins freely and its jets aren't clogged -- these are the first things to check before assuming a pump has failed.

Parts in this group on CDB3100AWE: WP99001791 (Pump Housing Filter).

Before you buy

Match CDB3100AWE exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.

How to confirm this is your model

On most dishwashers, the model and serial plate sits on the edge of the door or the tub rim. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.
