Dishwasher displays Fb and may not dry dishes properly.

Safety First: Turn off power at the breaker before accessing any panels.

• Confirm symptom: Dishes remain wet and there is little or no warm air when opening the door at the end of the cycle.
• Check for obstructions: Ensure nothing is blocking the vent area inside the door (often near the top or side).
• Use rinse aid: Verify that the rinse aid dispenser is filled and properly adjusted; poor drying can trigger related faults.
• Power reset: Reset power for 5 minutes and run a cycle to see if Fb returns.
• When to call for service: Persistent Fb indicates the vent fan assembly or control output must be tested and replaced by a professional.
