What the HCP error code actually means

Your Samsung washer has detected that a component on the internal heating control board got dangerously hot, over 150 degrees, and stayed that way long enough to trigger a safety shutdown. The washer stopped to prevent potential damage or a fire hazard. This issue typically requires inspection or replacement of internal electronic parts and is not something that can be resolved by simply restarting the machine.

Questions people ask about HCP

What does HCP mean on a Samsung washer?
The HCP code means the heater relay on the Heater PBA has overheated, specifically exceeding 150 degrees Celsius for 10 consecutive seconds. This is a safety fault that shuts down the washer to prevent further damage or fire risk. The Heater PBA is the board that controls the heating element circuit in your washer.
Is the HCP error on a Samsung washer a safety concern?
Yes, this error is a genuine safety concern. The HCP fault indicates a relay reached temperatures above 150 degrees Celsius, which is high enough to cause board damage or ignition in the surrounding area. Before attempting any inspection, unplug the washer from power and check the Heater PBA area carefully for any signs of burning, melted plastic, or scorching.
How much does it cost to repair an HCP error on a Samsung washer?
Repair costs depend on which component needs replacement. A Heater PBA typically costs in the range of $80 to $200 for the part alone, while a Main PCB can run $150 to $350 or more. Adding professional labor, total repair costs generally range from $200 to $500 depending on your location and the specific model. If the wiring is simply disconnected, the fix may cost little to nothing beyond your time.
Can I fix the HCP error myself?
You can start by checking the DC wiring harness connected to the Heater PBA for loose or disconnected plugs, which requires no parts and is a reasonable DIY step. However, if the board shows any signs of scorching or burn damage, or if reconnecting the wiring does not resolve the fault, the Heater PBA or Main PCB will need to be replaced. Board replacement typically requires some comfort with appliance electronics and should be handled carefully to avoid further damage.
Will resetting my Samsung washer clear the HCP error?
A simple reset is unlikely to permanently clear the HCP error because the fault is triggered by a physical overheating condition, not a temporary software glitch. Even if the code clears after a power cycle, it will return as soon as the relay reaches the threshold temperature again. The underlying cause, whether a faulty board, damaged relay, or wiring issue, must be corrected first.
