Hi CCU/Touchpad/LED assembly error (f21)
This error occurs if the touchpad/DED assembly is not able to transmit/receive data to/from the central control unit (CCU)
1. Check the touchpad/LED assembly by selecting different cycles and changing the modifiers and options available to confirm the touchpad/LED is responding 2. Unplug washer or disconnect power for five minutes. This will reset the CCU, and may reactivate the communication if the damage isn't severing. 3. Check Wire Harness connectors to the touchpad/LED assembly and Central Control Unit (CCU).
Please get back to us if you have further query else please accept the suggestion.

Hello &
Welcome to FixYa
F21 error is displayed when the washer is unable
to drain, press PAUSE/CANCEL button twice to clear the display. After this
please check the drain hose and drain pump filter for any blockages and make
sure it is not clogged with foreign particles. You can also check the drain
pump to verify that its working. Please get back to me if you have any other
questions.
