Dishwasher Error Code Help
Samsung Dishwasher HE Error Code
If your Samsung dishwasher displays HE, it usually points to a heater-related error or incorrect temperature detection during the wash cycle. A one-time reset may clear it, but repeat HE codes typically need service.
Quick Answer
Q: What does the Samsung dishwasher HE error code mean?
A: HE commonly indicates a heater error or that the dishwasher isn’t detecting temperature change the way it expects. If it repeats, likely causes include the heater, a thermistor (temperature sensor), wiring, or the control board.
Common Symptoms
- Dishwasher stops mid-cycle and displays HE
- Cycle ends early or drains out unexpectedly
- Dishes may come out cool/wet (not heating) or cycle behaves oddly during heating
- Error returns in the same part of the cycle (often during the heat phase)
Safety First
- If you smell electrical burning or see abnormal steam, shut off power at the breaker and stop using the dishwasher.
- Let the unit cool before restarting.
- Avoid accessing internal electrical components—heater circuits require proper testing equipment and safe procedures.
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 control 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 HE returns quickly, it’s likely a heater/sensor/control issue rather than user settings.
3) Confirm normal fill and wash sound
Heating faults can sometimes appear if the unit isn’t filling or circulating correctly. Listen for normal wash/circulation. If it sounds unusually quiet or like it’s not washing, stop and schedule service.
4) If HE repeats, stop and schedule service
Heater and temperature-sensing issues typically need electrical testing of the heater circuit and sensor readings. Continuing to run the dishwasher can lead to repeated shutdowns and unreliable cleaning performance.
Most Common Causes and Likely Parts
Heating system issues
- Heater not heating or heating inconsistently
- Heater relay/control output issue (model-dependent)
- Wiring/connector problem in the heater circuit
Temperature detection problems
- Thermistor (temperature sensor) reading incorrectly
- Loose connector or damaged harness
Control-side issue
- Control board misreading temperature or not driving the heater correctly
- Intermittent control behavior
When to Call Beacon
If HE returns after a reset and a normal test cycle, schedule service. The fix usually requires testing the heater circuit, thermistor readings, and control outputs.
Request service Call (352) 726-7530
Our friendly technicians in yellow can safely test the heater and temperature sensing circuit, inspect wiring/connectors, and confirm whether the control board is driving heat correctly. For service info, visit www.BeaconSaves.com.

FAQ
Is HE the same as an overheating code?
Not exactly. HE usually indicates a heater error or incorrect temperature detection, which can be “not heating enough” or “temperature behavior isn’t as expected.”
Can I clear HE by resetting the dishwasher?
You can try a breaker reset and then run a normal cycle. If HE returns, the underlying heater/sensor/control issue still needs repair.
What’s the most common cause of an HE error?
Common causes include a failing heater, a thermistor (temperature sensor) reading incorrectly, wiring/connector issues, or the control board not driving the heater properly.
Will the dishwasher still clean if it can’t heat properly?
It may wash, but results often suffer—grease and detergent performance depend heavily on correct water temperature.
Is it safe to keep running cycles when HE shows up?
If HE keeps returning, it’s best to stop using the dishwasher and schedule service. Continued operation can lead to repeated shutdowns and inconsistent performance.
When should I call Beacon for an HE error?
If HE returns after a reset and a normal test cycle, call Beacon so the heater circuit and thermistor readings can be tested safely.
