Washer-dryer combo displays PF and cycle stops unexpectedly, often after a power interruption.

Safety first: Ensure your hands are dry when handling power plugs or breakers.

Steps to address:

• Check household power: Verify that other appliances on the same circuit are working. Reset the breaker if tripped.
• Inspect plug and outlet: Ensure the Samsung combo's plug is fully inserted and the outlet is not loose or damaged.
• Restart cycle: After stable power is confirmed, restart the cycle or select a drain/spin if water remains in the drum.

When to stop: If PF appears frequently without actual power loss, the internal power supply or PCB may be failing and should be inspected by a technician.
