How to Fix Samsung Washer Error tE1
Problem: Heating element thermistor fault (models with water heater)

How to Fix tE1 Error
1. Access thermistor at bottom of tub near heating element (requires draining tub completely).
2. Disconnect power and verify tub empty before servicing.
3. Measure resistance as per tE procedure at ambient temperature.
4. Check connector for mineral deposits causing poor contact – clean with electrical contact cleaner and small brush.
5. Verify thermistor physically secured to tub with mounting clip (loose sensor gives False readings).
6. Replace thermistor DC34-00024A if resistance out of spec.
7. Verify heater element resistance separately (should read 20-30Ω) to rule out heater failure causing thermistor error.

How to Fix Samsung Washer Error 3E2
Problem: Erratic motor speed signal or hall sensor intermittent fault

How to Fix 3E2 Error
1. Inspect hall sensor wiring harness for chafing against sharp edges near motor mounting points.
2. Wiggle sensor connector while monitoring resistance with multimeter – intermittent changes indicate bad connection.
3. Replace hall sensor DC31-00138A if intermittent readings detected during wiggle test.
4. Check motor mounting bolts for looseness causing vibration-induced signal loss (torque to 15 ft-lbs).
5. Verify 15V DC supply to hall sensor at PCB connector pin 3 (critical for signal integrity).
6. If power supply unstable or signal distorted: replace main PCB DC92-01543A.
7. After repair, run diagnostic spin test to verify stable RPM feedback.

How to Fix Samsung Washer Error 3E3
Problem: Motor phase imbalance detected by inverter – winding fault or PCB issue

How to Fix 3E3 Error
1. Measure all three motor winding resistances (U-V, V-W, W-U) – must be within 5% of each other.
2. Check for burnt smell or discolored windings indicating internal short.
3. Inspect inverter board connections at motor terminals for arcing damage or loose screws.
4. Test inverter output waveforms with oscilloscope if available (requires technical expertise – should show clean 3-phase sine waves).
5. Replace main PCB/inverter assembly DC92-01543A as complete unit – individual component repair not recommended due to integrated design.
6. After replacement, perform motor calibration via service mode (Spin + Temp + Power, then navigate to calibration menu item

How to Fix Samsung Washer Error 3E4
Problem: Motor stall detection during acceleration – mechanical binding or sensor fault

How to Fix 3E4 Error
1. Verify drum rotates freely by hand (no bearing seizure) – should complete 3+ rotations when spun.
2. Inspect drive belt tension and condition – replace if glazed, cracked, or stretched (proper tension: 1/2″ deflection with 10 lbs pressure).
3. Check suspension rods for proper tension (all 4 should have equal resistance when pulled down 2 inches).
4. Test hall sensor operation as per 3E procedure with drum rotation.
5. Measure inverter DC bus voltage during startup attempt with multimeter (should maintain >300V DC under load).
6. Replace main PCB DC92-01543A if DC bus collapses during startup attempt indicating faulty power components.
7. Inspect tub bearings for roughness by rotating drum slowly – replace bearing kit if grinding noise present.
