Safety Information & Precautions

Critical warnings for technicians to prevent injury, electric shock, and damage to the appliance.

HazardPrecaution
Electrical ShockDisconnect power at outlet before servicing. Discharge capacitor.
Moving PartsEnsure washer is completely stopped. Keep hands clear of agitator/spin basket.
Sharp EdgesWear cut-resistant gloves when handling internal panels or components.
Hot SurfacesAllow motor and other components to cool before handling.
Chemical ExposureUse gloves when handling drain pump or hoses that may contain residual detergent.
Heavy LiftingUse proper lifting technique or assistance when removing counterweights or tub assembly.

Model Identification & Specifications

Identify the correct washer model using the serial tag location and decode technical specifications.

  1. Serial Tag Location: Typically inside the lid or on the rear panel.
  2. Model Number Format: WTW####### (e.g., WTW5000DW1). Verify against SM 8525146-A coverage list.
  3. Electrical Specs: 120V AC, 60Hz, 15 Amp dedicated circuit.
  4. Water Requirements: Hot and Cold water inlet pressure: 20-120 psi.
  5. Dimensions & Capacity: Standard top-load dimensions, 3.5-4.5 cu. ft. capacity.

WARNING! Always verify the model and serial number before ordering parts or proceeding with service. Using incorrect parts can cause malfunction or safety hazards.

Diagnostic Mode & Error Codes

Entering diagnostic mode and interpreting fault codes to isolate system failures.

  1. Enter Diagnostic Mode: Unplug washer. Press and hold specific buttons (e.g., "Start" + "Cancel"). While holding, plug power cord back in. Release buttons when display shows test code.
  2. Navigate Tests: Use cycle selector knob or buttons to scroll through component tests (e.g., Lid Lock, Drain Pump, Agitate, Spin).
  3. Common Error Codes:
    • F1/E1: Lid Lock/Switch Fault
    • F2/E2: Drain Timeout / Pump Fault
    • F5/E5: Motor Control / Triac Fault
    • F7/E7: Control Board Communication Error
    • F8/E8: Water Fill Timeout
  4. Clear Codes: Complete the diagnostic cycle or unplug the unit for 5 minutes.

CAUTION! Diagnostic mode may initiate automatic cycles. Keep hands clear of moving parts during tests.

Disassembly Procedures

Component Testing

Use a multimeter to test components for continuity, resistance, or proper voltage.

Lid Lock/Switch: Test for continuity when lid is closed/open. Water Inlet Valves: Test solenoids for proper resistance (typically 500-1500 ohms). Drain Pump: Test for continuity and check for obstructions. Motor: Test windings for shorts or opens. Shock Absorbers/Suspension: Check for smooth damping action, no leaks. Control Board: Visually inspect for burnt components. Check for proper output voltage to components during diagnostic tests.

Parts List & Exploded Views

Reference diagrams with callouts for part numbers.

  1. Locate the exploded view diagram for the relevant assembly (e.g., "Cabinet Assembly," "Drive & Tub Assembly").
  2. Match the callout number (e.g., 12, W10835678) to the parts list table.
  3. Order parts using the exact part number listed (e.g., Lid Switch Assembly - W10835678).

Tip: Always check for any service bulletins or updated part numbers before ordering.

Wiring Diagrams & Schematics

Detailed electrical schematics for tracing circuits.

  1. Identify the schematic corresponding to your model's control board version.
  2. Trace power from the inlet (L1, N, GND) through the main harness to components.
  3. Identify wire colors and connector references (e.g., J3, Pin 4 - Yellow/White wire).
  4. Use the schematic to verify voltage presence at test points during diagnostics.

WARNING! Always disconnect power before probing wires. Use diagrams to avoid short circuits.

Reassembly & Calibration

Reverse disassembly steps with attention to torque specifications and alignment.

  1. Ensure all seals and gaskets are properly seated (e.g., tub seal).
  2. Torque suspension rod nuts to specified value (e.g., 40 in-lbs).
  3. Reconnect all wire harnesses securely. Route wires away from moving parts.
  4. After reassembly, run calibration cycle (if applicable) via diagnostic mode to set motor positions.
  5. Perform a test wash cycle with no load to verify operation.

CAUTION! Overtightening can crack plastic components. Under-tightening can cause vibration and noise.

Performance Verification

Final checks to ensure repair is complete and washer operates to specification.

FunctionVerification TestPass Criteria
Water FillSelect Normal cycle, start.Both hot and cold valves open, tub fills to appropriate level within time limit.
AgitationDuring wash cycle.Agitator moves smoothly through full motion. No unusual noise.
Drain & SpinAfter agitation.Water drains completely. Spin basket accelerates smoothly to high speed. No excessive vibration.
Lid LockClose lid during spin.Lid locks immediately. Washer stops if lid is opened during spin.
Cycle CompletionRun full cycle.Cycle progresses through all stages and ends automatically. No error codes displayed.

SymptomPossible CauseCorrective Action
Washer won't start/powerNo power, lid switch, control boardCheck outlet, test lid switch for continuity, inspect control board for power LED.
No water fillWater valves, pressure switch, controlCheck water supply, test valve solenoids, test pressure switch tube for blockage/leaks.
Will not drain/spinDrain pump, lid lock, motor controlCheck pump for obstruction/continuity, verify lid lock engages, test motor and control board outputs.
Excessive vibration/noiseUnbalanced load, suspension, bearingsRedistribute load, inspect shock absorbers and springs, check tub bearings for wear.
Error code displayedSee Diagnostic Mode sectionEnter diagnostic mode, run corresponding component test, replace faulty part.

Reset Procedure: Unplug washer for 5 minutes to perform a hard reset on the electronic control.
