Problem: The pressure switch (water level sensor) signal is missing. The washer won’t run because it doesn’t know how much water is in the tub. Check connections or replace the switch.

How to Fix 7 Error

• UNPLUG washer from electrical power.
• Locate pressure switch (typically mounted on cabinet side wall or top rear of tub).
• Disconnect vinyl air hose from pressure switch port. Inspect hose for cracks, kinks, or water accumulation.
• Blow forcefully through hose to clear blockages. Replace hose if damaged.
• Test pressure switch with multimeter in continuity mode: switch must be OPEN when tub is empty. Blow into switch port—the switch should CLOSE with audible click.
• If switch fails to change state, replace using OEM part DC34-00050A: disconnect wiring harness, remove mounting screws, install new switch.
• Reconnect vinyl hose securely to both pressure switch and air dome port on tub.
• Verify air dome port is clear of lint/debris using flashlight and small brush.
• Reassemble panels. Run fill cycle to confirm water stops at correct level.

Problem: Flash code: 8 flashes = Overcurrent error; motor overload or short

How to Fix 8 Error

1. UNPLUG. Inspect motor harness for shorts/burns.
2. Test motor windings per LE steps.
3. Check for mechanical binding (foreign object, seized bearings).
4. Replace motor assembly (DC34-00030A) if faulty.

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 irregular voltage from the power outlet. This can be a home electrical issue, but often it is a failure of the main control board’s power supply.

How to Fix 9 Error

• Verify household voltage at washer outlet using multimeter. Must read 110-125V AC during operation.
• Check home circuit breaker panel: ensure washer circuit breaker is fully ON and connections are tight/clean.
• Confirm washer is on dedicated 15A+ circuit. Unplug other appliances sharing the circuit.
• UNPLUG washer. Remove rear panel to access main control board.
• Inspect board near power input terminals for burnt components, bulging capacitors, or charred traces.
• If household voltage is stable but error recurs, replace main control board using OEM part DC92-01003A.
• Transfer all connectors to new board one-by-one. Secure with mounting screws.
• Restore power. Monitor voltage during startup using multimeter to confirm stability.
• Install whole-house voltage regulator if home experiences frequent surges/brownouts.

Problem: Rare code: Unbalanced during spin with suspension fault detected

How to Fix UbC Error

1. UNPLUG. Remove top/front panels.
2. Inspect all 4 suspension rods: check for detached springs, broken mounts, or oil leaks.
3. Replace damaged rods (DC97-16350T). Torque mounting bolts to 18 ft-lbs.
4. Verify counterweight integrity (concrete blocks). Tighten bolts to 35 ft-lbs.

Problem: Water overflow detected during the fill cycle. The cold water inlet valve may be mechanically stuck open, forcing water into the machine continuously.

How to Fix OE1 Error

• UNPLUG washer immediately. Drain any standing water from tub using emergency drain hose.
• Locate pressure switch at top rear of tub assembly. Disconnect vinyl air hose.
• Test switch operation with multimeter in continuity mode: with tub EMPTY, switch must read OPEN circuit.
• If switch reads CLOSED when tub is empty, it is mechanically stuck.
• Attempt to free switch by tapping gently with plastic tool while monitoring multimeter. If no change, replace switch.
• Install new pressure switch using OEM part DC34-00050A: disconnect wiring harness, remove mounting screws, position new switch.
• Reconnect vinyl hose securely to switch and air dome port. Ensure no kinks in hose path.
• Verify air dome port on tub is clear of lint/debris using flashlight and small brush.
• Restore power. Run fill cycle to confirm water stops at appropriate level without overflow.

Problem: Water overflow detected during the wash cycle. The hot water valve may be stuck, or the machine is siphoning water back in through the drain hose.

How to Fix OE2 Error

• UNPLUG washer from electrical power.
• Observe tub interior for 10 minutes with washer OFF. If water level rises, inlet valve is leaking.
• Remove rear panel to access inlet valve assembly. Place towels underneath to catch residual water.
• Disconnect inlet hoses from valve ports. Inspect valve seats for mineral deposits or debris.
• Clean valve inlet screens with vinegar solution and soft brush. Rinse thoroughly.
• If leak persists after cleaning, replace entire inlet valve assembly using OEM part DC62-00120A.
• Disconnect wiring harness. Remove mounting screws. Extract old valve assembly.
• Install new valve assembly. Reconnect hoses (hand-tight plus 1/4 turn), wiring harness, and secure mounting screws.
• Restore power. Monitor tub for 15 minutes with washer OFF to confirm no water ingress.

Problem: Rare code: Steam generator error (steam-capable models)

How to Fix SC Error

1. UNPLUG. Access steam generator (front lower compartment).
2. Descale unit with vinegar solution per manual.
3. Test heating element resistance (should be 30-60Ω).
4. Replace steam generator assembly (DC97-18550A) if faulty.

Problem: The wash heater is overheating. The temperature sensor detected heat above safe limits. This is either a bad sensor or a stuck heater relay.

How to Fix HC1 Error

• UNPLUG washer from electrical power. Wait 20 minutes for components to cool completely.
• Remove lower front access panel to expose heater assembly mounted on tub front.
• Disconnect electrical wires from heater terminals. Label wires for correct reconnection.
• Test heater element resistance with multimeter: set to resistance mode. Proper reading is 20-40Ω.
• If multimeter displays OL (infinite resistance), element has open circuit and must be replaced.
• Remove mounting bolts securing heater to tub (typically 2-3 bolts). Note gasket position.
• Extract old heater assembly. Clean tub mounting surface thoroughly with isopropyl alcohol.
• Install new heater assembly using OEM part DC97-14470A with new gasket. Torque mounting bolts to 15 ft-lbs in crisscross pattern.
• Reconnect wires securely. Reassemble access panel. Run sanitize cycle while monitoring for leaks and proper heating.

Problem: The dryer heater (on combo units) is overheating. This is usually caused by a blocked air duct or a bad fan preventing proper airflow over the heater.

How to Fix HC2 Error

• UNPLUG washer from electrical power.
• Remove lower front access panel to access tub assembly.
• Locate thermistor mounted near heater assembly on tub wall. Disconnect wiring harness.
• Measure resistance across thermistor terminals with multimeter. At room temperature, should read ~10kΩ.
• If resistance reads near zero ohms (shorted) or fluctuates wildly, replace thermistor.
• Remove mounting screw securing sensor. Gently pry thermistor from tub wall without damaging threads.
• Clean mounting surface on tub with isopropyl alcohol. Apply thermal conductive paste to new sensor base.
• Install new thermistor using OEM part DC34-00040A. Secure with mounting screw tightened to 8 in-lbs.
• Reconnect harness. Inspect wiring for melted insulation near heater; repair if damaged.
• Reassemble panel. Run warm water cycle to verify temperature display updates smoothly.

Problem: No drain – water not evacuating within 15 minutes

How to Fix nd Error

1. Unplug washer and turn off water supply valves.
2. Remove lower front panel (3 screws at bottom edge).
3. Place towels underneath, then slowly unscrew drain pump filter cap counter-clockwise to release water gradually.
4. Clear all debris (coins, hairpins, lint) from filter housing and impeller chamber.
5. Manually rotate pump impeller clockwise with finger – should spin freely without grinding or binding.
6. Reinstall filter snugly (hand-tight plus 1/4 turn maximum – overtightening cracks housing).
7. Check drain hose for kinks beyond 90° bends and ensure standpipe height doesn’t exceed 96 inches.
8. If error persists: Disconnect pump wiring harness and measure resistance across terminals (should read 12-18Ω).
9. Replace drain pump assembly DC34-00008A if impeller damaged or motor open-circuit.
