Clean the drain area
Wipe the drain opening inside the oven cavity. Remove any visible food debris.
Use a damp cloth — do not push debris into the drain.

Power cycle and test
Turn off at breaker for 5 minutes. Restart and run a short steam cycle to test.
If F11 clears, increase descaling frequency to prevent recurrence.
