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.

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 RTW4340SQ0: W10123162 (Inglis Energy Guide), WP8578337 (Washer Water Temperature Switch), WP8317926 (Washer Break Hose), WP387240 (Ring Balance), W10880720 (Washer Ringtub), 285208 (Grease), 285790 (Clutch Lining Kit), 285438 (Brake Shoe Assembly), 285244 (Rear Leveling Foot), WP389140 (Drive Block - 2 5/16 Inch High), 350572 (Gearcase Oil), 3951311 (Clutch), 62570 (Gear), 63320 (Pinion), 389140 (Washer Drive Block), 350930 (Spray Paint - 12 oz. - White), 72017 (Touch-Up Paint - White).

Water inlet and drainage

Symptom: A washer that won't fill, fills slowly, won't drain, or leaves standing water in the tub.

Check: For fill problems, check the inlet valve's screen filters for sediment. For drain problems, check the pump for a jammed object and confirm the drain hose isn't kinked or looped too high.

Parts in this group on RTW4340SQ0: WP8578340 (Washer Water Inlet Valve), WPW10096921 (Washer Drain Hose), WP3360977 (Washer Water Inlet Syphon).

Controls, timers and wiring

Symptom: A cycle that doesn't advance, the wrong water level filling, an unresponsive display, or the washer 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 RTW4340SQ0: WP8572976 (Washer Timer Control), W10339251 (Water Level Pressure 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 RTW4340SQ0: 8318088 (Hinge Washer), 285901 (Counter Balance Spring Kit), WP62780 (Cabinet Retaining Clip), 285353 (Brake and Drive Tube Retainer Ring Kit), WP8536939 (Washer D-Shaped Knob Insert), 3349296 (Rack), 21366 (Washer Spanner Nut).

Suspension and tub hardware

Symptom: Excessive vibration, banging, or the machine "walking" during the spin cycle.

Check: Check that all leveling legs are actually contacting the floor, then inspect the suspension rods or springs for wear or a broken mount point.

Parts in this group on RTW4340SQ0: WP3355758 (Agitator Cap), 285811 (Agitator Repair Kit), WP64065 (Washer Suspension Spring Bracket), WP389387 (Shaft, Agitator (Complete)), 285565 (Agitator Kit), WP63907 (Suspension Spring), 388952 (Drive Basket).

Door, lid switches and latches

Symptom: The washer won't start, or it stops mid-cycle as soon as the lid is opened.

Check: Listen for an audible click when the lid closes. No click, or a visibly cracked plastic tab on the latch, points to this part.

Parts in this group on RTW4340SQ0: WP8318084 (Washer Lid Switch), WP21258 (Lid Hinge Bearing), WPW10119828 (Lid Hinge Mounting Screw), 8318084 (Washer Lid Switch Assembly).

Drive system (belts, pulleys, motors)

Symptom: A drum or tub that won't turn, a burning-rubber smell, or a loud thump or squeal during a cycle.

Check: With power off, turn the drum or tub by hand -- resistance or grinding points to the motor or a bearing, and a cracked, glazed, or snapped belt is visible once the cabinet is open.

Before you buy

Match RTW4340SQ0 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 washers, the model and serial plate sits under the lid or on the back panel. 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.
