Washers take more abuse than almost any appliance in the house. Every cycle fills the tub with water, spins a heavy wet load at high speed, and drains it again, often several times a day in a busy household or laundromat-style rental. That workload wears out a predictable set of parts: lid switches and door locks, drain pumps, door boots, motor couplers, agitator dogs, shift actuators, tub bearings and water inlet valves.
When a washer won't spin, won't drain, leaks on the floor or sounds like a jet engine, one of those parts is usually the culprit. Replacing the right component costs far less than a new machine, and on many top-load and front-load platforms the repair is straightforward for a technician or a mechanically capable owner. This category stocks Supco washer parts built to fit the major brands, including Whirlpool, Kenmore, Maytag, GE, Frigidaire, Samsung and LG.
Before ordering, pull the model and serial number from the tag (under the lid, on the door frame or on the back panel) and match the OEM part number. Washer parts change between model years more than most people expect.
A water inlet valve with hot and cold solenoids opens on command from the control to fill the tub. A pressure switch or water level sensor tells the control when the tub is full. The motor then drives agitation or tumbling. On a direct-drive top loader, a plastic and rubber motor coupler links the motor to the transmission; on many belt-drive and newer direct-drive machines, a shift actuator or mode shifter tells the transmission whether to agitate or spin.
Top loaders with a dual-action agitator use small plastic agitator dogs (cogs) that let the upper section ratchet in one direction. Front loaders tumble the load in a horizontal drum supported by a pair of bearings and a seal at the rear of the outer tub. The door boot, a rubber gasket between the cabinet and tub, keeps water in during tumbling.
Safety interlocks keep the machine from spinning with the lid or door open. Top loaders use a lid switch or lid lock assembly; front loaders use a door lock that latches mechanically and reports its status to the control. At the end of the cycle, the drain pump pushes water out through the drain hose.
Every washer repair starts with the model number. Use it to find the parts diagram and OEM part number, then match that number to the replacement. Supco product pages list the OEM numbers each part replaces.
| Symptom | Likely Part | Washer Type | Quick Check |
|---|---|---|---|
| Won't spin, lid closed | Lid switch / lid lock | Top-load | Continuity with lid closed; error code |
| Won't start, door lock error | Door lock assembly | Front-load | Lock engages and reports locked |
| Motor hums, no agitation | Motor coupler | Direct-drive top-load | Broken plastic drive forks |
| Upper agitator slips | Agitator dogs | Top-load, dual-action | Upper section turns freely both ways |
| Won't switch from agitate to spin | Shift actuator | Many top-load models | Error code; actuator test |
| Water left in tub | Drain pump | All | Clear filter and hose first |
| Roaring during spin | Bearing kit | Front-load, some top-load | Rumble when drum is spun by hand |
| Won't fill or overfills | Water inlet valve | All | Solenoid resistance; inlet screens |
Supco has been making replacement parts since 1945, and their washer components are built to match OEM fit and function. HVAC365 product pages carry OEM cross-reference numbers and spec details so you can confirm the match before checkout. Washer parts in this category ship in 3-5 business days, which matters when a family or a rental unit is waiting on laundry.
Check the lid switch or lid lock first, since it is the most common cause. If the interlock tests good, look at the motor coupler on direct-drive models or the shift actuator on models that use one. Fault codes, if your model displays them, can narrow it down quickly.
The door boot traps water, lint and detergent residue in its folds. Over time it can mildew, tear or harden. A torn boot leaks during tumbling and needs replacement. Wiping the boot dry after use and leaving the door cracked helps a new one last.
It depends on the machine. Bearings are inexpensive, but the labor is significant. On a quality front loader with no other problems, a bearing kit with a new seal is often worth it. Have a technician inspect the tub and spider for corrosion before committing.
On some models, yes. If the pump housing is intact and the motor is sold separately for your model, motor-only replacement works. If the housing is cracked or the impeller is damaged, use the full assembly.
They are small plastic cogs inside a dual-action agitator that let the upper section ratchet in one direction to roll clothes down into the load. When they wear, the upper agitator spins freely. They're inexpensive and usually replaced as a set.
Signs include slow fill, no fill on hot or cold, or water entering the tub with the washer off. Clean the inlet screens first. If the screens are clear and the solenoids test out of range, replace the valve.
