Samsung Washer Error Code FC — What It Means & How to Fix It

What Does This Error Mean?

The FC error on a Samsung washer indicates a problem with the frequency or the motor control circuit. The washer's inverter board controls the motor speed by adjusting electrical frequency. When the inverter cannot communicate with the motor properly, the FC code appears and the cycle stops. Symptoms include the drum not spinning at the right speed, stopping mid-cycle, or not spinning at all.

Affected Models

Samsung front-load washers with inverter motor
WF45R6100AW
WF50R8500AV
WF56H9100AG
WF210ANW and other Samsung front-load models

Common Causes

Faulty inverter board that controls motor speed and frequency
Hall sensor on the motor providing incorrect speed feedback to the inverter
Loose or damaged wiring harness between the inverter board and the motor
Motor windings have failed or developed a short, drawing unexpected current
Overheating of the inverter board due to blocked ventilation or a prolonged heavy load

How to Fix It

Unplug the washer for 5 minutes and plug it back in. This resets the inverter board and control board. Try running a short cycle to see if the error clears.

A temporary power fault or software glitch can trigger FC. A reset resolves it in some cases.
Check that the washer is not overloaded. Remove half the load, redistribute the remaining clothes evenly around the drum, and restart the cycle.

Overloading stresses the inverter by making the motor work too hard. This can trip the inverter's protection circuit and log FC.
Make sure the washer has adequate ventilation. If it is in a tight enclosed cabinet, ensure air can circulate around the back and bottom. An overheated inverter will shut down and log FC.

The inverter board generates heat during operation. Adequate airflow is essential for reliable performance.
Inspect the wiring harness running from the control area to the motor at the bottom rear of the machine. Look for loose connectors, pinched wires, or any signs of burning.

A disconnected harness connector on the motor or inverter is an easy fix — just reconnect it and retest.
If the error persists after reset and inspection, have a technician test the hall sensor and inverter board. These components require specialized testing equipment to diagnose accurately.

Replacing the inverter board is the most common fix for a persistent FC error. The hall sensor is an inexpensive secondary suspect.

When to Call a Professional

The inverter board and motor sensor are not straightforward DIY repairs. This code almost always requires a trained appliance technician. An inverter board for Samsung washers typically costs $100 to $200 for the part alone. Total repair including labor is usually $200 to $400.

Frequently Asked Questions

What is an inverter board on a washing machine?

An inverter board is an electronic circuit that controls the motor speed. Instead of using a traditional motor with a belt or gears, inverter washers use a variable-speed motor driven by the inverter. This makes the washer quieter, more energy efficient, and more reliable. When the inverter fails, the motor cannot spin at the right speed.

Is FC a common Samsung washer error?

FC is less common than drain or door errors, but it does occur on models with inverter motors. It tends to appear after 5 or more years of use when the inverter board starts to age. Overloading the machine regularly can accelerate inverter wear.

Can I replace the inverter board myself?

It is technically possible if you are comfortable with appliance repair. The inverter board is located at the rear of the machine and requires accessing the back panel. However, without a multimeter and knowledge of how to test motor circuits, it is difficult to confirm the inverter is actually the faulty part. Professional diagnosis before ordering parts is recommended.
