E11 — Control Board Checksum (Memory) Error

E11 is a checksum error — the main control board's memory failed its internal check and has become corrupted. It is not a communication loss between the user interface and main control board.

Keep using it?
Yes, with caution
DIY difficulty
Moderate

How to fix it

  1. Unplug the dryer for 5 minutes to fully power down the control, then retry — this clears a one-off memory glitch in some cases.
  2. If E11 returns, the control board's memory has failed its checksum and won't self-correct — replace the main electronic control board.
  3. Plug the dryer into a surge protector rated for major appliances after repair to reduce the chance of recurrence.

  • Power surge or brownout corrupted control board memory An electrical disturbance scrambled the stored checksum data.
  • Failing control board memory The memory circuit on the main control board is degrading and no longer checks out correctly.
