What the HC3 error code actually means

Your Samsung washer has detected a problem with the heating element used during the drying cycle. Either a wire has come loose from the heater, or the heater itself has developed an electrical fault. The machine has stopped to prevent potential damage or a safety hazard, and the heater connection or component will need to be inspected and likely repaired.

Questions people ask about HC3

What does HC3 mean on a Samsung washer?
HC3 is a heater check error indicating that the drying heater circuit has a fault, either a short circuit or a disconnected wire. The control board detected an abnormal electrical condition in the drying heater and stopped operation to prevent further damage. This code typically appears on Samsung washer-dryer combo models that include a built-in drying function.
Is it safe to keep using my washer with an HC3 error?
You should not continue using the drying function while the HC3 error is active. A short-circuited heater presents an electrical hazard, and an open circuit means the dryer will not heat at all. The washing function may still operate normally, but the underlying fault should be diagnosed and corrected before attempting any dry cycle.
How much does it cost to repair the HC3 error on a Samsung washer?
If only a wire needs to be reconnected or repaired, the cost is minimal, typically just the service call fee if a technician is involved. Replacing the drying heater element itself generally costs between $50 and $150 for the part, plus $100 to $250 in labor if you hire a professional. Total repair costs can range from around $150 to $400 depending on the specific part needed and your location.
Can I fix the HC3 error myself?
In some cases, yes. Start by unplugging the machine and inspecting the wire connector at the drying heater for any loose or disconnected pins. If the connector is intact and secure, testing the heater element with a multimeter for continuity will tell you whether the element itself has failed. Wire reconnection is a straightforward repair, but replacing the heater element requires some disassembly and comfort working with appliance components.
Will resetting the washer clear the HC3 error?
A power reset may temporarily clear the error code, but it will return as soon as the control board checks the heater circuit again during a drying cycle. The HC3 code indicates a real electrical fault in the heater or its wiring, and a reset does not address the underlying problem. The fault must be physically repaired before the error will stay cleared.
