What happens after the washer warms?

FF clears after thawing and water moves normally

Run a supervised rinse or spin test and inspect every visible hose connection for leaks.

OE appears after thawing

The drain hose or pump path may still be frozen or restricted.

IE appears after thawing

The faucet, inlet hose, or water-supply path may still be frozen.

FF remains in a warm room

Verify the complete model and arrange temperature-sensing or control diagnosis.
