Dishwasher Error Code Help
Samsung Dishwasher HC Error Code
If your Samsung dishwasher displays HC, it typically points to a high-temperature / heater overheat condition. Sometimes it’s a one-time glitch that clears after a power cycle, but recurring HC usually means the heater circuit or temperature sensing needs service.
Quick Answer
Q: What does the Samsung dishwasher HC error code mean?
A: HC commonly indicates the dishwasher detected a high-temp heater/overheat condition or abnormal temperature rise. If it returns after a reset, likely causes include the heater circuit, a thermistor (temperature sensor), wiring, or the control board.
Common Symptoms
- Dishwasher stops mid-cycle and shows HC
- Unit drains and shuts down for protection
- Dishes come out unusually hot, or cycle ends early
- Error returns in the same portion of the cycle (often during heating)
Safety First
- If you smell electrical burning or see steam that seems excessive, turn off power at the breaker and stop using the dishwasher.
- Let the unit cool before restarting or inspecting anything.
- Avoid pulling the dishwasher out if you’re not comfortable working around plumbing/electrical—call Beacon instead.
Homeowner Quick Checks
1) Power cycle the dishwasher
Turn the dishwasher off at the breaker (preferred) for 2 minutes, then restore power. This can clear a one-time temperature sensing glitch.
2) Run a normal cycle (no extra-high-temp options)
Try a standard Normal cycle and avoid “Sanitize” or extra high-temp options for the test run. If HC returns quickly, it’s more likely a component or sensing problem.
3) Make sure the dishwasher can fill and circulate normally
Heating problems can sometimes show up if water isn’t moving correctly. Confirm the dishwasher filled with water at the start and you heard normal wash/circulation sounds. If it sounds unusually quiet or “dry,” stop and schedule service.
4) Check your hot water settings (basic sanity check)
If your household water is set extremely hot, it can push temperatures higher than expected. Typical home hot water setpoints are much lower than scalding temperatures. If you suspect your water heater is set unusually high, consider having it checked.
Most Common Causes and Likely Parts
Heater circuit issues
- Heating element / heater circuit fault
- Heater relay sticking (model-dependent)
- Wiring/connector heat damage or loose connection
Temperature sensing problems
- Thermistor (temperature sensor) reading incorrectly
- Sensor harness connection issue
Control-side issue
- Control board misreading temperature or driving heat incorrectly
- Intermittent control behavior causing abnormal heating
When to Call Beacon
If HC returns after a power cycle and a normal test cycle, schedule service. Heater/overheat errors usually require electrical testing of the heater circuit, sensor readings, and control outputs.
Request service Call (352) 726-7530
Our friendly technicians in yellow can check heater operation, verify thermistor readings, inspect wiring and connectors, and confirm whether the control board is driving heat correctly. For service info, visit www.BeaconSaves.com.

FAQ
Is Samsung dishwasher HC the same as an overheating code?
Yes. HC generally relates to a high-temperature or heater/overheat condition detected during the cycle.
Can I keep using the dishwasher if HC pops up occasionally?
If it was a one-time event that clears and doesn’t return, it may have been a glitch. If HC returns, stop using it and schedule service to prevent damage.
What’s the first thing I should do when HC appears?
Power cycle the dishwasher at the breaker for a couple minutes, then run a normal cycle without extra-high-temp options.
What parts most commonly cause an HC code?
The most common suspects are the heater circuit (element/relay/wiring), the thermistor (temperature sensor), and the control board.
Could extremely hot household water trigger HC?
It can contribute, especially if combined with high-temp cycle options. If your water feels scalding at the sink, consider having your water heater settings checked.
When should I schedule service for an HC error?
If HC returns after a reset and a normal test run, schedule service so the heater circuit and temperature sensing can be tested safely.
