What Cold / Eco Warm means

Samsung washers without a digital display report problems with blinking lights instead of codes, and a blinking Cold or Eco Warm temperature light is the pattern for a jammed button. The control reads a button as stuck or pressed continuously. This follows the same meaning as the bE2 and E2 group on washers with a numeric display. You see the light flashing and the washer may ignore button presses.

Common causes of Cold / Eco Warm

  • Control panel button held down or swollen
  • Debris or moisture under the buttons
  • Panel button contact
  • Main board button input
✓ One safe check you can try

1. Turn the washer off. 2. Press each button on the panel and work it back and forth so you reach every edge. 3. Wipe the panel dry and keep sprays off the buttons. 4. Turn the washer on again. If the light keeps blinking or a button looks damaged, request service.

! Why to stop there
  • A button that still reads pressed after being freed points to the panel contacts.
  • We test each button's response and the main board input.
  • We confirm the blinking pattern matches this meaning on your model.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Cold / Eco WarmCold / Eco Warm questions
What does the Cold light blinking mean?

On these washers a blinking Cold or Eco Warm light is the pattern for a jammed button. It is the same condition that numeric-display washers show as bE2.

Will freeing the button fix it?

Often. Working each button back and forth releases a sticky one. If the light returns, the panel needs a look. If the light returns after cleaning around the buttons, the panel contacts need testing and we price that in writing.

Is it dangerous?

No. It is a button reading problem, not a water or heat issue. Still, a washer that will not take presses should be checked if cleaning does not help.
