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.

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).

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.

Problem: Power failure during cycle operation – informational code after outage

How to Fix PF Error

1. This is informational code, not a fault – appears after unexpected power loss during cycle.
2. Press Power button to clear display and restart desired cycle.
3. If washer won’t restart: unplug 5 minutes to reset PCB memory completely.
4. Check household circuit breaker for partial trip (reset fully OFF then ON position).
5. Verify GFCI outlet hasn’t tripped (common in laundry rooms with moisture exposure).
6. If PF appears without actual power loss: replace noise filter DC96-00488A (False trigger from voltage spike or failing filter).
7. Consider installing UPS backup for areas with frequent brief power interruptions.

Problem: Button error; control panel key stuck or shorted

How to Fix bE Error

1. UNPLUG. Press all buttons firmly 5x to dislodge debris.
2. Remove control panel: disconnect ribbon cable. Inspect for moisture/corrosion. Clean contacts with isopropyl alcohol.
3. Test button matrix continuity with multimeter.
4. If short persists, replace main control board (DC92-01003A). Recalibrate after installation.

Problem: Heater relay stuck closed or temperature runaway condition

How to Fix CE Error

1. UNPLUG WASHER – safety critical check before proceeding.
2. Test heating element resistance for shorts to ground (should read OL between terminals and tub/chassis).
3. Inspect element for blistered coating or bulging indicating internal short to ground.
4. Measure thermostat continuity – should open at 185°F (85°C) when heated with heat gun.
5. Replace heating element DC47-00013A if shorted to ground (fire hazard).
6. Replace main PCB DC92-01543A if element and thermostat test good (stuck relay RL

8. NEVER operate washer with this error until repaired – fire hazard exists from uncontrolled heating element operation.

Problem: Alternative drain error code on specific Samsung models (WF45T series)

How to Fix SE Error

1. Clear drain filter completely.
2. Remove pump assembly by disconnecting wiring harness, loosening hose clamp at discharge port, and rotating pump counter-clockwise 1/4 turn to release from mounting bracket.
3. Inspect impeller for hair/fiber wrapping around motor shaft – clean thoroughly with needle-nose pliers.
4. Check pump housing for cracks near mounting points.
5. Test impeller rotation resistance – should spin freely with moderate drag.
6. Reinstall pump ensuring O-ring seal properly seated in groove.
7. Replace drain pump DC34-00008A if impeller damaged or housing cracked.
