Problem: Motor tachometer/hall sensor signal error – no speed feedback to inverter

How to Fix 3E Error

1. Unplug washer and remove rear panel.
2. Locate hall sensor connector on motor stator (3-wire white connector near motor windings).
3. Disconnect and inspect for corrosion or bent pins – clean with contact cleaner if needed.
4. Measure resistance between pins 1-2 (should read
5. 5-3kΩ), pins 2-3 (same value).
6. Rotate drum manually 360° while monitoring resistance – should fluctuate smoothly without jumps.
7. Replace hall sensor DC31-00138A if open circuit or erratic readings detected.
8. If sensor tests good: check motor windings (U-V, V-W, W-U should read 5-15Ω balanced within 5%).
9. Replace main PCB DC92-01543A if motor and sensor both test good but error returns immediately on restart.

Still Not Working?

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: The washer cannot detect the motor’s speed or position. This is usually caused by a failed Hall Sensor on the motor or a loose wire connection. The machine stops immediately to prevent damage.

How to Fix 3C Error

1. • UNPLUG the washer from electrical power and wait 5 minutes.
   • Remove the rear access panel to expose the motor assembly and wiring harness.
   • Inspect the motor harness connector at both ends for burn marks, corrosion, or bent pins. Clean contacts with electrical contact cleaner and a soft brush.
   • Test motor windings resistance between terminals U-V, V-W, and W-U using a multimeter. All readings must be equal (typically 2-5Ω). Uneven readings indicate motor failure.
   • Test the hall sensor resistance within the motor assembly per service manual specifications (typically
   • 5-
   • 5kΩ between designated pins).
   • Verify ground continuity at motor mounting bolts—ensure tight connection to chassis.
   • If motor tests faulty, replace entire motor assembly using OEM part DC34-00030A: remove drive belt, stator mounting bolts, and rotor assembly. Install new motor, reattach belt with proper tension, and reconnect all wiring.
   • Reassemble panels and run diagnostic test cycle to verify operation.

Problem: Leak detection sensor activated – moisture detected in base pan

How to Fix LC Error

1. Unplug washer and tilt machine 45° backward (use furniture dolly or 2 assistants) to drain base pan water completely.
2. Remove lower front panel and inspect leak sensor (small white disc under tub center with 2 wires).
3. Dry sensor thoroughly with hair dryer on cool setting for 5 minutes – moisture causes False triggers.
4. Trace water source systematically: check inlet valve connections, drain pump housing seals, tub gasket, and all hose connections for drips.
5. Run empty rinse cycle while observing base pan with flashlight to pinpoint leak source.
6. Replace leak sensor DC96-01703A if base pan dry but error returns immediately (corroded contacts).
7. If slow drip found at inlet valve: replace valve assembly DC62-00243A to prevent recurrence.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: Thermistor (temperature sensor) open circuit or short circuit

How to Fix tE Error

1. Unplug washer and remove lower front panel.
2. Locate thermistor mounted on outer tub bottom (white plastic sensor with 2-wire harness).
3. Disconnect connector and measure resistance at room temperature (70°F/21°C = ~12kΩ).
4. Compare to thermistor resistance chart: 32°F=35kΩ, 104°F=5kΩ, 140°F=
5. 5kΩ.
6. Submerge sensor in ice water bath – resistance should increase smoothly to 30-40kΩ.
7. Replace thermistor DC34-00024A if reading OL (open) or 0Ω (short) or unstable fluctuations.
8. Inspect wiring harness for rodent damage or pinched wires near tub mounting points.

Still Not Working?

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: The temperature sensor (thermistor) is broken or disconnected. The machine has stopped heating because it cannot read the water temperature. Replace the sensor if the wiring looks good.

How to Fix TE Error

• UNPLUG the washer from electrical power.
• Remove the lower front access panel to access the tub assembly.
• Locate the thermistor mounted on the front of the outer tub. Disconnect its wiring harness.
• Measure resistance across thermistor terminals using a multimeter set to resistance mode. At room temperature (70°F/21°C), reading should be approximately 10kΩ (±10%).
• If resistance reads infinite (open) or near zero (shorted), replace the thermistor.
• Remove the mounting screw securing the sensor. Extract old thermistor and install new OEM part DC34-00040A, ensuring metal surface makes full contact with tub wall.
• Reconnect wiring harness. Inspect entire harness path for damage near tub movement points; repair if necessary.
• Reassemble access panel. Run hot water cycle to verify temperature readings stabilize correctly.

Problem: Heater element fault or temperature sensor mismatch during heating cycle

How to Fix HE Error

1. Disconnect power and drain tub completely before servicing.
2. Access heating element at bottom front of outer tub (remove lower panel and element cover plate).
3. Measure element resistance between terminals (20-30Ω normal; OL = open circuit failure).
4. Test thermistor resistance adjacent to element (should match main tub thermistor values within 10%).
5. Verify 120V AC present at element terminals during heat cycle using multimeter (measure through access hole).
6. Replace heating element DC47-00013A if open circuit or terminals burnt/corroded.
7. Replace thermistor DC34-00024A if resistance mismatched to actual water temperature (verify with separate thermometer).
8. If both test good: replace main PCB DC92-01543A (faulty heater relay RL
9. .

Still Not Working?

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: The water is getting too hot, or the sensor thinks it is. This is often a relay on the main control board stuck in the ‘On’ position, forcing the heater to run continuously.

How to Fix hE Error

• UNPLUG the washer from electrical power. Wait 15 minutes for components to cool.
• Remove the lower front access panel to expose the heater assembly mounted on the tub.
• Disconnect electrical wires from heater terminals. Label wires for correct reconnection.
• Test heater element resistance using multimeter: proper reading is 20-40Ω. Infinite resistance indicates open element.
• Inspect wiring insulation near heater connections for melting, burns, or damage. Repair damaged sections.
• Replace faulty heater assembly using OEM part DC97-14470A: remove mounting bolts, extract old heater, clean tub mounting surface thoroughly, install new gasket, position new heater, and torque bolts to 15 ft-lbs.
• Reconnect wiring securely. Verify thermistor is functional per TE error procedure before testing.
• Reassemble panel. Run sanitize cycle while monitoring for leaks and proper heating.

Problem: Overflow error – excessive water detected in tub beyond maximum level

How to Fix OE Error

1. Cancel cycle and allow washer to drain naturally through pump operation.
2. Inspect pressure tube routing – must have drip loop below tub connection to prevent siphoning of water into tube.
3. Test water level sensor operation as per 1E procedure with frequency meter.
4. Verify drain pump activates before fill cycle completes (prevents cumulative overfill on consecutive fills).
5. Check inlet valve for slow leak after cycle end – replace valve assembly if dripping observed during 10-minute post-cycle observation.
6. Replace water level sensor DC96-01703C if frequency signal erratic or stuck at low-frequency value.
7. Ensure drain hose height doesn’t exceed 96 inches causing backpressure during drain that triggers False overflow.

Still Not Working?

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: Excess suds detected – non-HE detergent or overdosing causing foam buildup

How to Fix SUD Error

1. Cancel current cycle and select Rinse+Spin cycle without detergent 2-3 times to remove suds.
2. Use only HE (High Efficiency) detergent labeled specifically for front-load washers.
3. Reduce detergent amount to 1-2 tablespoons (15-30ml) for standard loads; 1 tablespoon for soft water areas.
4. Avoid liquid fabric softener – use dryer sheets instead (softener coats drum causing suds retention).
5. Clean detergent dispenser drawer thoroughly with warm water and old toothbrush to remove residue buildup.
6. Run Tub Clean cycle monthly with affresh tablet or 1 cup white vinegar to remove soap scum buildup.
7. Check water hardness – soft water requires less detergent than hard water (use water test strip to determine dosage).

Still Not Working?

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: The washer detects too many suds. This happens when you use non-HE detergent or too much soap. The cycle pauses to let the bubbles dissolve.

How to Fix SD Error

• Pause the wash cycle immediately when SD error appears.
• Wait 30-45 minutes without opening door to allow suds to naturally dissipate.
• After waiting period, select RINSE+SPIN cycle with NO detergent added.
• Run cycle to flush suds. Repeat rinse cycle if suds remain visible in dispenser or drum.
• Remove all laundry. Wipe door gasket folds, detergent dispenser drawer, and drum interior thoroughly with damp microfiber cloth.
• For prevention: Use ONLY HE (High-Efficiency) detergent. Reduce dose to 1/2 manufacturer recommendation.
• Never use regular detergent, non-HE pods, or fabric softener sheets. Use liquid fabric softener in dispenser drawer only.
• Run empty tub clean cycle monthly with affresh washer cleaner.
