Documented failures

Transmission

Usually DIY

Price this one before starting — a top-load transmission is one of the most expensive individual parts on the machine; weigh it against a replacement washer first.

Try this first — it costs nothing. Rule out the belt before anything else — see drive belt above; a slipped or broken belt produces the identical 'motor runs, nothing moves' symptom.

Check, in this order

  1. TOP-LOAD only — front-load washers have a direct-drive motor bolted to the drum and no separate transmission.
  2. Confirm the belt is intact and seated first (see drive belt above) — a slipped belt mimics a dead transmission exactly and costs nothing to rule out.
  3. With the belt confirmed good, listen during agitate and spin: grinding or a burning smell from underneath points at the transmission's own gears or clutch.

Before you open anything

Tools

The repair, in order

  1. Remove the agitator and the outer tub cover to expose the transmission mount.
  2. Photograph the belt routing and every wiring connector near the transmission before disturbing anything.
  3. Disconnect the drive belt from the transmission pulley and unbolt the transmission from its mount.
  4. Fit the replacement transmission and reconnect the belt in the photographed routing.
  5. Reinstall the agitator and confirm nothing binds before restoring power.

How you know it worked. The machine agitates and spins normally through a full cycle with no grinding and no burning smell.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Repair or replace? Replace the transmission only after confirming the basket/agitator drive is the source; its labor and part cost make a technician quote worth comparing with replacement on an older laundry center.General guidance for this component — no model-specific price maths behind it.

Lid lock

Usually DIY

DIY. If a new lock still won't register closed, check the wiring harness for a chafe point near the hinge before condemning a second part.

Try this first — it costs nothing. Clean the strike and switch area of detergent residue and lint first — a gummed-up striker often won't seat even though the lock itself is fine.

Check, in this order

  1. TOP-LOAD only — front-load washers use the door lock on the boot, covered separately above.
  2. Confirm the lid actually closes flush and nothing is holding it open — the switch can't sense a lid that isn't fully down.
  3. Listen for a click as the lid closes; no click at all points at the switch/lock assembly rather than its wiring.
  4. With power off, test the switch's continuity with the lid held shut versus open before ordering a new assembly.

Before you open anything

Tools

The repair, in order

  1. Unplug the washer and remove the console or lid-hinge trim to reach the lock/switch assembly — this varies by brand, so photograph screws and clips as you go.
  2. Photograph the wiring harness plug before disconnecting it.
  3. Unscrew the lid lock/switch assembly from the tub flange or console.
  4. Fit the replacement, reconnect the photographed harness, and reinstall the trim.

How you know it worked. The lid locks (or the switch registers closed) at the start of a Spin cycle, and the cycle completes without stopping for a lid fault.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Repair or replace? This is normally a repair-first part: a confirmed failed lid lock is modest relative to a replacement laundry center.General guidance for this component — no model-specific price maths behind it.

Drain pump

Usually DIY

DIY. Escalate only if the pump is fine and the drain error persists, which points at the control board or wiring.

Try this first — it costs nothing. Clean the drain filter - manual: MAINTENANCE.

Check, in this order

  1. Clean the drain filter behind the lower access panel FIRST - a coin or lint clog mimics a dead pump exactly and costs nothing.
  2. Confirm the drain hose is not kinked and its end is below 96 in (2.4 m) - the manual lists both as the drain error causes.
  3. With power off, spin the pump impeller by hand; if it is seized or noisy, replace the pump.

Before you open anything

Tools

The repair, in order

  1. Open the lower access panel and drain through the filter hose into a shallow pan.
  2. Remove and inspect the pump filter — coins, hair clips and lint clog it and mimic a dead pump exactly.
  3. If the filter was clean, photograph the pump's wiring connectors, then unplug them.
  4. Release the hose clamps to the sump and the drain hose; expect more water.
  5. Unscrew the pump from its mount, fit the replacement, and reconnect clamps and connectors in the photographed order.
  6. Run a Rinse+Spin with the panel still off and watch for leaks before closing up.

How you know it worked. Run Rinse+Spin. A good repair drains fully within the drain step with no drain error and no drip at either clamp.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Repair or replace? Repair first when the pump is confirmed blocked, leaking, or electrically failed; consider replacement only if major drive or control faults are present too.General guidance for this component — no model-specific price maths behind it.

Water inlet valve

Usually DIY

Replacing the valve is DIY. BUT if the machine keeps filling when it should not, close the faucets, unplug it and call for service - do not attempt that one.

Try this first — it costs nothing. Clean the inlet filter screens - manual: Cleaning the Water Inlet Filters.

Check, in this order

  1. Check both faucets are fully open and the hoses are not kinked - the manual's first two the fill error causes.
  2. Clean the inlet filter screens (manual: MAINTENANCE > Cleaning the Water Inlet Filters); hard-water scale is a common cause and needs no parts.
  3. If the machine fills with the power off, the valve is stuck open and must be replaced.

Before you open anything

Tools

The repair, in order

  1. Close both faucets and unscrew the inlet hoses from the back of the machine.
  2. Pull the filter screens out with pliers and soak them in white vinegar (manual: Cleaning the Water Inlet Filters) — scale here causes the fill error with no part needed.
  3. If the screens were clean, remove the top panel to reach the valve body.
  4. Photograph the wiring and hose positions — hot and cold are not interchangeable.
  5. Swap the valve, reconnect in the photographed order, and reattach the hoses.
  6. Open the faucets and check for weeping at both couplings before running a cycle.

How you know it worked. Machine fills at a normal rate on a cold and a warm cycle, and does NOT fill when powered off.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Repair or replace? Repair first after screen, hose, and faucet checks rule out supply issues; this valve is a contained, lower-cost repair.General guidance for this component — no model-specific price maths behind it.

Agitator

Usually DIY

DIY. If the agitator's own splines are fine but it still won't turn, the fault is in the transmission or belt below it, not the agitator.

Try this first — it costs nothing. Check nothing is jammed in the agitator's base or dogs before assuming it's broken — a jammed agitator can look sheared when it isn't.

Check, in this order

  1. TOP-LOAD only — front-load washers tumble the drum itself and have no agitator to inspect.
  2. With the lid open, grab the agitator and try to rock it side to side and lift it — genuine play or a cracked base confirms the part rather than a drive problem underneath it.
  3. Run a short cycle and watch whether the agitator moves at all: no movement while the tub fills points at the transmission or belt instead, covered separately.

Before you open anything

Tools

The repair, in order

  1. Pry the cap off the top of the agitator with a putty knife to reach the retaining bolt.
  2. Remove the retaining bolt and lift the agitator straight up off its shaft — it can be a tight fit.
  3. Inspect the base and any internal dogs/cam for cracks or stripped splines before fitting the replacement.
  4. Seat the new agitator fully on the shaft, refit the retaining bolt, and press the cap back on.

How you know it worked. The agitator strokes back and forth through a normal wash fill with no play at the base.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Capacitor

Usually DIY

DIY. If a new capacitor still hums without turning the drum, the motor windings or the belt/transmission are the next suspects, not a second capacitor.

Try this first — it costs nothing. Nothing free here — a failed start capacitor is a part swap, but it's cheap, so confirm the hum-with-no-turn symptom before assuming a bigger motor fault.

Check, in this order

  1. Applies to belt-drive washers with a separate motor start/run capacitor — many direct-drive washers don't use one at all, so confirm the platform has one before ordering.
  2. The classic symptom is the motor humming loudly on Spin or Agitate but never actually turning — hum with no movement is the capacitor's signature.
  3. Check the capacitor's mounting bracket for bulging, leaking, or a burst top — a visibly swollen capacitor confirms it without testing.

Before you open anything

Tools

The repair, in order

  1. Locate the capacitor and its bracket, usually near the motor at the back or underside of the cabinet.
  2. Photograph the wiring before disconnecting the two leads from the old capacitor.
  3. Unscrew the bracket and remove the old capacitor.
  4. Fit the replacement in the same bracket and reconnect the leads exactly as photographed.

How you know it worked. The motor starts turning immediately on Spin and Agitate with no prolonged hum.

Dispenser

Usually DIY

DIY.

Try this first — it costs nothing. No no-part fix for this one - go straight to the checks.

Check, in this order

  1. Confirm the leak is the housing and not the drawer seal or the inlet hose above it.
  2. With water supplies off, inspect the housing hose connections for looseness, cracks, or a wet trail before ordering the housing.

Before you open anything

Tools

The repair, in order

  1. Confirm the leak is the housing and not the drawer seal or the feed hose above it.
  2. Remove the top panel to reach the housing and its hoses.
  3. Photograph hose positions, swap the housing, reseat every clamp.

How you know it worked. No water escaping around the drawer on a fill.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Repair or replace? Repair first if the housing is cracked or leaking after hose and drawer checks; the single dispenser part is far below laundry-center replacement cost.General guidance for this component — no model-specific price maths behind it.

Door switch

Usually DIY

DIY. If continuity is fine, the fault is upstream — the timer or thermostat on the dryer half.

Try this first — it costs nothing. Clean around the switch plunger — lint and dryer-sheet residue build up here and can hold the plunger out exactly like a bad switch.

Check, in this order

  1. This is the DRYER half of a stacked laundry center or washer/dryer combo unit — the dryer won't start or won't run with the door shut, even though the washer side works normally.
  2. Press the switch by hand with the door open and watch/listen for the dryer attempting to start — no response points at the switch or its wiring rather than the timer or thermostat.
  3. Check the door actually latches fully and nothing is holding it open a crack.

Before you open anything

Tools

The repair, in order

  1. Remove the door or the switch's console/bezel trim to reach the switch, prising gently with a putty knife.
  2. Photograph the wiring, then disconnect the switch.
  3. Test the old switch's continuity in both the pressed and released positions before condemning it.
  4. Fit the replacement switch, reconnect the wiring, and refit the trim.

How you know it worked. The dryer half starts as soon as the door is shut and stops immediately when it's opened mid-cycle.

Control board

Usually DIY

Borderline. The board is the most expensive part on this machine and is commonly misdiagnosed - get a technician to confirm before buying one.

Try this first — it costs nothing. No no-part fix for this one - go straight to the checks.

Check, in this order

  1. Confirm power at the outlet and that PF (power failure) is not simply latched - press Start/Pause first.
  2. Rule out the cheaper failures the board gets blamed for (pump, valve, door lock) before buying a board.
  3. Look for visible scorching or swollen capacitors on the board.

Tools

The repair, in order

  1. Rule out the cheap failures the board gets blamed for — pump, valve, door lock — first.
  2. Check for PF (power failure) simply latched: press Start/Pause.
  3. Inspect the board for scorching or swollen capacitors.
  4. If replacing, transfer connectors one at a time against your photographs.

Repair or replace? Obtain a repair quote after connector and power checks; a control board can be economical alone but should be compared with replacement if several electronic or drive faults coexist.General guidance for this component — no model-specific price maths behind it.

Drain hose

Usually DIY

DIY.

Try this first — it costs nothing. No no-part fix for this one - go straight to the checks.

Check, in this order

  1. Inspect the full run of hose for kinks, crushing behind the machine, and splits at both clamps.
  2. Verify the standpipe height against the manual's 24-96 in (61-244 cm) window; too high causes the drain error, too low siphons.
  3. Confirm there is no airtight seal at the standpipe - the manual warns this siphons water out of the drum.

Before you open anything

Tools

The repair, in order

  1. Pull the machine out far enough to see the whole hose run.
  2. Check for kinks, crushing behind the cabinet and splits at both clamps.
  3. Confirm the standpipe height sits inside the manual's 24–96 in (61–244 cm) window.
  4. Make sure the connection is NOT airtight — the manual warns a sealed joint siphons the drum.
  5. Replace the hose if split, reseating both clamps.

How you know it worked. A full drain step with no pooling behind the machine and no drain error.

In your manual: the manual — checked; its troubleshooting section does not cover this part.

Heating element

Usually DIY

TECHNICIAN for a persistent heating error. The element itself is a DIY part only once a technician has confirmed the diagnosis.

Try this first — it costs nothing. No no-part fix for this one - go straight to the checks.

Check, in this order

  1. Confirm the cycle actually heats - many cold/eco cycles never do, which is not a fault.
  2. Follow the manual's heating error step: unplug 60 minutes, restore power, retry.
  3. If the heating error persists after that reset, call for service.

Before you open anything

Tools

The repair, in order

  1. Check the cycle is one that actually heats; many eco cycles never do.
  2. Follow the manual's heating error step: unplug 60 minutes, restore power, retry.
  3. If the heating error persists, have the element and its thermistor tested for continuity before replacing.
  4. Access is behind the lower front or rear panel depending on revision — photograph the terminals.
  5. Fit the element, ensuring the mounting nut is snug enough to seal the gasket.

How you know it worked. Wash water warms on a hot cycle and the heating error does not return.
