Match the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
Show stop conditions
- The code returns after one power reset
- Water or the cabinet becomes excessively hot, there is smoke/odor, or a breaker trips
- The PCB relay, thermistor, heater, or wiring must be electrically tested
Likely causes
- The heater relay is not switching as the control expects on supported older models
- The wash-water heater circuit is not heating correctly
- A thermistor or temperature-feedback signal is abnormal
- The relay, PCB, wiring, or heater circuit needs model-specific electrical diagnosis
Quick checks, in order
Record when Hr appears
Note the cycle and whether the washer is trying to heat wash water. Hr is treated by Samsung as a washer heater/heater-relay error rather than a drying-stage HC2 condition.
Power-cycle once
Switch the washer off for 2–3 minutes, restore power, and retry one normal cycle. Do not repeatedly reset a returning heater code.
Check for overheating symptoms
If water is unusually hot, the cabinet smells electrical, or a breaker trips, stop use immediately.
Leave relay and heater testing to service
PCB relay, thermistor, heater resistance, wiring, and live-voltage checks require qualified electrical diagnosis.
Does Hr return when the washer enters a heated wash stage?
The heater, temperature feedback, relay, wiring, or control remains the relevant fault area. Arrange model-specific service after one reset attempt.
That pattern strengthens the case for a wash-heating circuit or temperature-feedback problem rather than a drain, balance, or drying-only fault.
Verify the exact display and model documentation; Samsung uses separate drying-heater codes such as HC2 on supported FlexWash/washer-dryer families.
Stop and get qualified help when
- The code returns after one power reset
- Water or the cabinet becomes excessively hot, there is smoke/odor, or a breaker trips
- The PCB relay, thermistor, heater, or wiring must be electrically tested
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does Hr mean on a Samsung washer?
Samsung's current washer code guide groups Hr with heater errors, and older model-specific Samsung support describes Hr as missing heater-relay operation. The exact circuit varies by model, so use the full model number before replacing parts.
Is Hr a drying-heater code?
Not in the Samsung washer guidance used for this page. Hr is treated as a washer heater/heater-relay fault; HC2 is separately documented on supported FlexWash/washer-dryer families for the drying heater.
Can I test the heater relay myself?
Not as a normal user-level check. Relay, thermistor, heater-resistance, and live-voltage testing involves internal electrical components and should be handled by qualified service.
