Problem: Flash code: 7 flashes = Power supply fault (non-display models); voltage instability or outage

How to Fix Dryer Error

• Verify household electrical power is stable. Check circuit breaker panel to ensure dryer’s dedicated 30A breaker is fully ON.
• Measure voltage at dryer outlet with multimeter during operation – must maintain 220-240V AC. Significant drops indicate circuit overload.
• Inspect power cord and terminal block connections inside dryer for looseness, corrosion, or arcing damage. Tighten terminals to 15 in-lbs torque if accessible.
• Ensure dryer is on dedicated circuit with no other high-draw appliances sharing the line.
• For recurring voltage issues: Install whole-house voltage regulator or dedicated UPS for dryer circuit.
• After verifying stable power, restore dryer operation and monitor for error recurrence during multiple cycles.

Problem: Flash code: 8 flashes = Moisture sensor fault (non-display models)

How to Fix Dryer Error

• UNPLUG dryer from electrical power.
• Open dryer door. Locate moisture sensor bars inside drum (typically two parallel metal strips on front bulkhead).
• Clean sensor bars thoroughly with isopropyl alcohol and non-abrasive cloth to remove fabric softener residue or buildup.
• Inspect sensor bars for cracks, corrosion, or physical damage. Check wiring harness connections at sensor and main board.
• Test sensor circuit continuity per service manual specifications using multimeter.
• If bars are damaged or circuit tests faulty, replace moisture sensor assembly using OEM part DC34-00042A.
• Remove mounting screws securing sensor assembly. Disconnect wiring harness. Install new assembly ensuring proper alignment.
• Reconnect harness. Reassemble components. Restore power and run auto-dry cycle with damp load to verify proper cycle termination.

How to Fix Dryer Error

• UNPLUG dryer from electrical power for 15 minutes to reset electronics.
• Restore power and check if error clears. If persistent, proceed.
• Remove rear access panel to access main control board.
• Inspect board thoroughly for burnt components, bulging capacitors, or charred traces near processor chip.
• Check all board mounting screws and ground connections for tightness and corrosion.
• If visual inspection shows damage or error persists after reset, replace main control board using OEM part DC92-01003A.
• Transfer all connectors to new board one-by-one. Secure board with mounting screws to 5 in-lbs torque.
• Restore power. Enter service mode per model instructions to initialize board and verify all subsystem operations function correctly.

Problem: Unbalanced load detected during spin cycle

How to Fix UE Error

1. Pause cycle and redistribute laundry evenly around drum circumference.
2. Remove 1-2 bulky items if overloaded (max 80% drum capacity).
3. Ensure large items (blankets, rugs) are balanced with smaller items.
4. Restart cycle.
5. If persistent: Level machine using adjustable feet (front feet turn clockwise to raise, counter-clockwise to lower; rear feet auto-level).
6. Check suspension rods for damage – access requires removing top panel (3 screws at rear) and inspecting 4 suspension rods at drum corners for broken springs or detached hooks.
7. Test spin cycle empty to verify mechanical balance before reloading.

If the Samsung washer UE error returns after leveling the washer, reducing the load size, and redistributing items, stop and recheck the full model number, suspension movement, tub balance, spin behavior, and wiring before buying another component.

Problem: Alternative display format for unbalanced load error on specific models

How to Fix Ub Error

1. Pause cycle and redistribute laundry evenly.
2. Reduce load size to maximum 80% drum capacity.
3. Ensure machine is level on solid floor (use carpenter’s level on drum).
4. Check that shipping bolts were completely removed during installation (4 bolts at rear of drum with plastic caps).
5. Inspect drum bearings for excessive play by lifting drum vertically at 12 o’clock position – should have <1/8" movement.
6. Test spin cycle empty to verify mechanical balance before reloading.

Problem: Unstable current/voltage supply detected during operation – fluctuation >15%

How to Fix UC Error

1. Unplug washer for 30 seconds to reset PCB memory and clear transient fault.
2. Verify dedicated circuit not shared with other appliances causing load fluctuations.
3. Check outlet wiring for loose neutral connection (major cause of UC errors – measure neutral-ground voltage <2V).
4. Test noise filter DC96-00488A input/output voltage drop under load (should be <2V difference with 10A load).
5. Replace noise filter if excessive voltage drop or physical damage present.
6. If error recurs within first minute of cycle: replace main PCB DC92-01543A (faulty voltage monitoring IC).
7. Install line conditioner if household voltage fluctuates >10% during operation (common in rural areas).

Problem: Drain system fault – pump failure or main PCB relay issue

How to Fix 5E Error

1. Clear drain filter thoroughly as per nd procedure.
2. Disconnect power for 10 minutes to reset PCB memory.
3. Inspect pump wiring harness at connector J4 on main PCB – look for burnt pins or moisture corrosion.
4. Reconnect power and enter diagnostic mode: press Temp + Delay Start + Power simultaneously, then press Temp 4 times to activate drain pump.
5. Listen for pump operation – if silent but voltage present (measure 120V AC at connector during drain cycle), replace drain pump DC34-00008A.
6. If no voltage at pump connector: check PCB relay RL4 continuity with multimeter (should read closed circuit when energized).
7. Replace main PCB DC92-01543A if relay defective or traces burned near relay location.

4. 5 PSI.
5. Inspect pump volute for foreign objects (remove 3 screws securing pump to tub assembly).
6. Rotate impeller manually – replace pump if binding or broken vanes detected.
7. Check for siphoning: ensure drain hose has proper air gap at standpipe (not sealed airtight).
