Samsung Dryer ET / EE — EEPROM / Control Board Memory Error

Samsung Dryer · Error code ET

What ET Means

The main control board failed to read or write its own memory. The board can't reliably store cycle settings — usually indicates a failing PCB.

Symptoms

  • ET or EE on display
  • Settings don't save between cycles
  • Random cycle behavior
  • Dryer won't accept any cycle selection

Common Causes

1
Corrupted EEPROM on main board

Memory chip failed — board replacement is typical fix.

2
Power surge damage

Recent lightning or grid surge corrupted firmware.

3
Loose ribbon between UI and main board

Intermittent connection causing read failures.

4
Failed voltage regulator on PCB

Marginal supply voltage causing memory faults.

How to Fix It

  1. Unplug the dryer for 10 minutes and try again — a hard reset occasionally clears soft EEPROM errors.
  2. Reseat the ribbon cable between the user interface board and the main control board.
  3. Inspect both boards for burn marks, swollen capacitors, or surge damage.
  4. If ET returns and you've reset/reseated everything, replace the main control board.
  5. Install a surge protector on the dryer outlet to prevent recurrence.
