The SM 8525146-A is the official service manual for specific Whirlpool top-loading washer models. This document provides authorized technicians with comprehensive information for diagnosis, disassembly, repair, and reassembly. It includes safety warnings, technical specifications, exploded views, wiring diagrams, error code interpretation, and step-by-step troubleshooting procedures. Below are key sections covering safety, model identification, component access, testing, and replacement instructions.
Critical warnings for technicians to prevent injury, electric shock, and damage to the appliance.
| Hazard | Precaution |
|---|---|
| Electrical Shock | Disconnect power at outlet before servicing. Discharge capacitor. |
| Moving Parts | Ensure washer is completely stopped. Keep hands clear of agitator/spin basket. |
| Sharp Edges | Wear cut-resistant gloves when handling internal panels or components. |
| Hot Surfaces | Allow motor and other components to cool before handling. |
| Chemical Exposure | Use gloves when handling drain pump or hoses that may contain residual detergent. |
| Heavy Lifting | Use proper lifting technique or assistance when removing counterweights or tub assembly. |
Identify the correct washer model using the serial tag location and decode technical specifications.
WARNING! Always verify the model and serial number before ordering parts or proceeding with service. Using incorrect parts can cause malfunction or safety hazards.
Entering diagnostic mode and interpreting fault codes to isolate system failures.
CAUTION! Diagnostic mode may initiate automatic cycles. Keep hands clear of moving parts during tests.
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.
Reference diagrams with callouts for part numbers.
Tip: Always check for any service bulletins or updated part numbers before ordering.
Detailed electrical schematics for tracing circuits.
WARNING! Always disconnect power before probing wires. Use diagrams to avoid short circuits.
Reverse disassembly steps with attention to torque specifications and alignment.
CAUTION! Overtightening can crack plastic components. Under-tightening can cause vibration and noise.
Final checks to ensure repair is complete and washer operates to specification.
| Function | Verification Test | Pass Criteria |
|---|---|---|
| Water Fill | Select Normal cycle, start. | Both hot and cold valves open, tub fills to appropriate level within time limit. |
| Agitation | During wash cycle. | Agitator moves smoothly through full motion. No unusual noise. |
| Drain & Spin | After agitation. | Water drains completely. Spin basket accelerates smoothly to high speed. No excessive vibration. |
| Lid Lock | Close lid during spin. | Lid locks immediately. Washer stops if lid is opened during spin. |
| Cycle Completion | Run full cycle. | Cycle progresses through all stages and ends automatically. No error codes displayed. |
This appliance complies with relevant UL (Underwriters Laboratories) standards and NSF/ANSI residential appliance requirements. Contains materials that must be recycled or disposed of properly according to local regulations.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Washer won't start/power | No power, lid switch, control board | Check outlet, test lid switch for continuity, inspect control board for power LED. |
| No water fill | Water valves, pressure switch, control | Check water supply, test valve solenoids, test pressure switch tube for blockage/leaks. |
| Will not drain/spin | Drain pump, lid lock, motor control | Check pump for obstruction/continuity, verify lid lock engages, test motor and control board outputs. |
| Excessive vibration/noise | Unbalanced load, suspension, bearings | Redistribute load, inspect shock absorbers and springs, check tub bearings for wear. |
| Error code displayed | See Diagnostic Mode section | Enter 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.
