Samsung Washer Error Code HH — What It Means & How to Fix It

What Does This Error Mean?

The HH error on a Samsung washer indicates a problem with the heating element or the water temperature sensor circuit. Samsung washers that use heated water for sanitize or hot wash cycles monitor the heating system closely. HH typically means the temperature sensor has detected an abnormal reading, the heater has failed, or there is a wiring fault in the heating circuit. The washer will stop the cycle to prevent overheating or washing with cold water when hot is required.

Affected Models

WF45R6100AW
WF50R8500AV
Samsung front-load washers with internal heaters
WF42H5000AW
WF45T6000AW — models with sanitize and steam wash cycles

Common Causes

Heating element inside the washer has burned out and can no longer heat the wash water
Water temperature sensor (NTC thermistor) has failed and is sending an out-of-range signal
Wiring harness to the heating element or temperature sensor is damaged or has a loose connection
Scale or mineral buildup on the heating element causing it to overheat and trip a thermal fuse
Thermal cutout fuse on the heater circuit has blown due to overheating from scale or prolonged high-heat use

How to Fix It

Turn the washer off and unplug it from the wall. Leave it off for 10 minutes and then try again. Occasionally the HH error is a temporary sensor glitch that clears with a power reset.

If the code returns within the next cycle or two, the fault is real and needs investigation.
Avoid running hot or sanitize wash cycles until the fault is resolved. Running the washer on cold water cycles will not trigger the heating system and may let you continue using the machine for basic loads while waiting for repair.

This is a temporary workaround only — the underlying fault should still be diagnosed and fixed.
If you are comfortable doing a basic inspection, pull the washer away from the wall and check the power cord and rear panel wiring for visible damage. Look for any burned or melted wires near the back of the machine where the heater connections are.

Do not open the machine or touch internal components without unplugging first and confirming all stored energy is discharged.
Check if you are in a hard-water area. Mineral scale buildup on heating elements is a common cause of heater failures. Running a drum-clean cycle with a washing machine cleaner or descaler monthly reduces scale buildup and extends heater life.

White vinegar or citric acid powder are effective descalers for regular maintenance. Run an empty hot cycle with the cleaner once a month.
Have a technician test the heating element resistance and temperature sensor readings. A heating element reads a specific resistance value when healthy — a reading of open (infinite) or near-zero resistance confirms the element has failed. The NTC sensor should change resistance predictably with temperature.

A complete heating element replacement kit for Samsung front-loaders typically includes the element, gasket, and mounting hardware.

When to Call a Professional

Replacing a washing machine heating element requires draining the drum, removing the back panel, and working with electrical components. This is best left to an appliance technician unless you are comfortable with appliance repair. Expect $150 to $300 for diagnosis and heating element replacement.

Frequently Asked Questions

Does the HH error mean my Samsung washer has permanently failed?

Not necessarily. HH most commonly means the heating element or its sensor needs replacement — not that the entire washer is at fault. Heating element replacement is a standard appliance repair and usually costs far less than a new washer.

Can I still wash clothes if my Samsung washer shows HH?

Yes — for basic cold or warm water washes that do not require the internal heater. Avoid the sanitize, steam, or high-temperature wash cycles until the heater is repaired. For most everyday laundry, a cold or warm tap-water cycle is sufficient.

How long does a Samsung washer heating element last?

Typically 7 to 12 years with normal use. Hard water areas shorten heater life significantly due to scale buildup. Regular descaling maintenance can extend the heating element's life considerably.
