Samsung Washing Machine EE Error Code
Control board EEPROM memory fault
What this error means
EE is an EEPROM fault—the main control cannot read stored calibration and cycle data reliably. Samsung may flash random segments or refuse cycles until the board passes self-test.
How EE is detected
When EE appears on a Samsung washing machine, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung WA50R5400AW, Samsung WF45K6500AV, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most EE calls are resolved without parts: unplug 60 seconds and retry—ee from a single glitch sometimes clears once. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If EE returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Lightning or brownout corrupting EEPROM chip
- Age-related memory failure on decade-old boards
- Moisture intrusion after base pan leak
- Failed firmware write during interrupted SmartThings update
Step-by-step fixes
- 1Unplug 60 seconds and retry—EE from a single glitch sometimes clears once
- 2Move the washer to a dedicated grounded outlet without shared loads
- 3Record model and serial before calling—EE repair is usually board swap
- 4Compare repair cost to machine age before ordering a main PCB
When to call a technician
Persistent EE after one clean power cycle requires main control board replacement and reprogramming.
Affected models
- Samsung WA50R5400AW
- Samsung WF45K6500AV
- Samsung WF50K7500AV
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines to prevent EE from lint and food debris buildup.
- Record when EE appears in the cycle and whether it clears after a 60-second power reset on your Samsung washing machine—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for EE; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting EE; reversed plugs on pumps and valves cause immediate repeat faults.
