Diagnostic Procedures
| Error Code | Description | Diagnostic Procedure |
|---|---|---|
| LE | Motor Error | Check motor wiring, measure motor resistance (should be 2-5Ω between phases) |
| FE | Flooding Error | Check flood switch continuity, inspect for water leaks in base pan |
| TE | Temperature Error | Test NTC sensor resistance (10kΩ at 25°C), check heater continuity |
| DE | Door Lock Error | Measure door lock resistance, check microswitch operation |
| PE | Pressure Sensor Error | Test pressure sensor voltage (0.5-4.5V), check air tube for blockages |
| IE | Water Inlet Error | Test inlet valve coils (2-4kΩ), check water pressure (20-116 psi) |
Advanced Diagnostics
Motor Testing
Measure phase-to-phase resistance (2-5Ω) and insulation resistance (>10MΩ). Check hall sensor signals during drum rotation.
Control Board Diagnostics
Verify power supply voltages (+12V, +5V), test communication lines, check for burnt components or cold solder joints.
Sensor Calibration
Perform pressure sensor zero calibration, verify temperature sensor accuracy, calibrate load sensing system.
Repair Instructions
Motor Replacement
Remove rear panel, disconnect motor wiring, remove mounting bolts. Install new motor with proper torque specifications (8-10 Nm).
Drum Bearing Service
Complete disassembly required. Remove spider assembly, press out old bearings, install new bearings with proper alignment.
Control Board Repair
Identify faulty components using schematic. Replace relays, capacitors, or power transistors as needed. Test all functions after repair.
Door Seal Replacement
Remove front panel, release spring wire retainer. Clean seating surface, install new seal with proper alignment and lubrication.
Shock Absorber Service
Access through base panel. Remove mounting bolts, compress and remove old shocks. Install new shocks with proper orientation.
Heater Element Replacement
Access through rear panel. Disconnect wiring, remove mounting nuts. Install new element with proper thermal compound and torque.
