Display shows PF after a power outage; unit may beep but otherwise operates normally.

Safety: Ensure your electrical circuit is properly grounded and not overloaded.

Steps:

• Confirm power stability: Check that the outlet is supplying steady power and that no other appliances are causing breaker trips.
• Clear the alert: Press and hold the appropriate button combination (often the power or light button for 3–5 seconds) as described in the Costway manual to clear PF.
• Secure the plug: Make sure the power cord is fully inserted into the outlet and not loose.
• Monitor: If PF recurs frequently without actual outages, have an electrician check the circuit and consider using a surge protector rated for appliances.
