Samsung Dishwasher error code HC
HC
What it means
High temperature heater error - the temperature inside the dishwasher is too hot.
Likely causes
- The temperature inside the dishwasher is too hot
Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.
Safe first checks
- Switch the power to the dishwasher off (30 seconds) and then on again, at the circuit breaker
- Empty the dishwasher
- Fill the detergent drawer, and then start a Normal cycle
When to call a pro
If the error occurs again after that cycle, request service from Samsung. Do not open the machine to reach the heater - heater work is for a technician.
Repair or replace?
Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
