Problem: Low voltage detection (<90V AC) or power surge event triggering protection

How to Fix 9E1 Error

1. Measure wall outlet voltage under load with multimeter (minimum 105V AC required during operation).
2. Check for shared circuit with high-draw appliances (AC units, microwaves) causing voltage sag.
3. Inspect power cord connections at terminal block inside machine – tighten screws to 8 in-lbs if loose.
4. Test noise filter DC96-00488A for continuity between input/output terminals (should read <
5. 5Ω).
6. Replace noise filter assembly if open circuit or burnt appearance on components.
7. If filter good but error returns within 10 seconds of power-up: replace main PCB DC92-01543A (faulty voltage monitoring circuit).
8. Install dedicated 120V/15A circuit if household voltage unstable below 105V during operation.

Still Not Working?

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

Problem: High voltage detection (>140V AC) or power anomaly triggering protection

How to Fix 9E2 Error

1. Measure wall outlet voltage with multimeter (should be 110-125V AC nominal).
2. Check for utility voltage spikes using recording voltmeter over 24 hours (common during grid switching).
3. Inspect noise filter DC96-00488A for bulging capacitors or burnt varistors (look for discoloration).
4. Test MOV (metal oxide varistor) resistance across L-N terminals (should read OL when cold; <100Ω indicates failure).
5. Replace noise filter assembly DC96-00488A if MOV shorted or filter damaged.
6. If filter tests good but error immediate on power-up: replace main PCB DC92-01543A.
7. Consider whole-house surge protector installation for recurring high-voltage events.

Problem: Flood condition; water leak detected by floor sensor under tub

How to Fix FL Error

1. UNPLUG IMMEDIATELY. Remove standing water.
2. Tilt washer forward to access base. Locate leak sensor (flat pad under tub). Dry thoroughly.
3. Inspect all hoses, pump, tub seals for leaks. Common culprits: torn door bellow (DC64-00110A), cracked tub, loose hose clamps.
4. Replace faulty component. Test fill/drain cycles with panels off to verify no leaks.

Problem: Pause error; cycle interrupted unexpectedly (door opened mid-cycle)

How to Fix PA Error

1. Close door firmly until latch clicks.
2. Press START/PAUSE button to resume.
3. If unresponsive: Power cycle washer (unplug 2 mins). Restart cycle from beginning.

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

Problem: Heater circuit fault – open circuit or short in heating system wiring

How to Fix HC Error

1. Test heating element resistance as per HE procedure (20-30Ω normal).
2. Inspect element terminals for corrosion or loose connections (clean with wire brush if corroded).
3. Check high-limit thermostat continuity mounted adjacent to element (should read closed at room temp, open at 185°F).
4. Measure voltage drop across element during operation (should see near full line voltage 110-120V AC).
5. Replace heating element DC47-00013A if open circuit or terminals burnt.
6. Replace thermostat if open circuit at room temperature.
7. If element and thermostat good but no voltage at terminals: replace main PCB DC92-01543A (faulty heater relay).

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

Problem: Temperature control error; heater not reaching target temp

How to Fix TC Error

1. UNPLUG. Test thermistor (DC34-00040A) and heater elemen per HE steps.
2. Check continuity of heater relay on main board.
3. Replace faulty sensor or main board (DC92-01003A).

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

Problem: Pressure switch error; water level sensor malfunction

How to Fix PC Error

1. UNPLUG. Remove pressure switch hose. Blow through to clear moisture/debris.
2. Test switch continuity per 5E steps.
3. Replace pressure switch (DC34-00050A).
4. Verify air dome port on tub is clear of lint/debris.

Still Not Working?

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

Problem: The machine is not filling with water fast enough. Check for kinked hoses or clogged screens on the water inlet valves. If water pressure is good, the valve itself may be broken.

How to Fix E1 Error

• UNPLUG washer immediately. Remove standing water under unit with towels or wet/dry vacuum.
• Tilt washer forward carefully (with assistance) to access base pan. Locate moisture sensor pad under tub.
• Dry sensor pad thoroughly with lint-free cloth. Allow 60 minutes air drying time.
• Inspect door bellow gasket for tears, cracks, or mold buildup. Stretch gasket to check entire circumference.
• If bellow damaged, replace using OEM part DC64-00110A: remove spring clamp, extract old bellow, install new bellow ensuring lip seats fully in tub groove, secure with new clamp.
• If bellow intact, check tub weld seams, pump housing, and hose connections for leaks. Tighten loose clamps.
• If sensor remains triggered after drying and leak repair, replace moisture sensor using OEM part DC34-00060A.
• Reassemble. Run fill/drain test cycle with panels off to confirm no leaks before final reassembly.

Problem: The washer is not draining. This is almost always a clogged drain pump filter (coin trap) or a broken drain pump. Check the filter at the bottom front of the machine first.

How to Fix E2 Error

• UNPLUG the washer from electrical power.
• Locate pressure switch at top rear of tub assembly. Disconnect thin vinyl air hose from switch port.
• Blow forcefully through vinyl hose to clear moisture, lint, or debris. Inspect hose for cracks/kinks; replace if damaged.
• Test pressure switch operation: set multimeter to continuity mode. With tub empty, switch should read OPEN. Blow firmly into switch port—the switch should click and read CLOSED.
• 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 on tub is clear of lint/debris using flashlight and small brush.
• Reassemble panels. Run fill cycle to confirm water level stops at appropriate height.

Problem: The washer detected an overflow level of water. This typically happens if the water inlet valve is stuck open and lets water in even when the machine is off.

How to Fix E3 Error

1. • UNPLUG washer from electrical power. Remove rear access panel.
   • Manually rotate drum pulley. Listen for grinding noises or feel for excessive resistance indicating bearing failure.
   • Disconnect motor wiring harness from main board. Label connections before removal.
   • Test motor windings resistance between U-V, V-W, and W-U terminals. All readings must be equal (2-5Ω). Uneven readings indicate internal fault.
   • Test hall sensor resistance per service manual pinout (typically
   • 5-
   • 5kΩ between sensor pins).
   • If motor binds mechanically or electrical tests fail, replace entire motor assembly using OEM part DC34-00030A.
   • Remove drive belt, stator mounting bolts (4-6 bolts), and rotor nut (requires rotor puller tool). Extract old motor.
   • Install new motor assembly. Reattach rotor, stator bolts (torque to 22 ft-lbs), and drive belt with proper tension.
   • Reconnect wiring. Run motor diagnostic test to verify rotation direction and speed.
