Samsung Dishwasher Code HE: Temperature Reading

Medium · inspection needed

Code: HE
Appliance: Dishwasher
Brand: Samsung
Warranty: 30-day workmanship

What HE means

On Samsung US dishwashers with a digital display, HE is a heater error that means the temperature inside the dishwasher is being detected incorrectly. It is about sensing rather than about heat itself: the control cannot trust what it reads, so it stops the cycle and shows HE. This is a brand-wide code and names no model. A related code on the DW80T series, HC1, describes a heater that fails to warm the water, which is a separate condition.

Common causes of HE

Temperature sensor reading outside a believable range
Sensor wiring and connections
The heating circuit
Whether the code returns after a power reset

✓ One safe check you can try

1. Empty the dishwasher. 2. Make sure the detergent drawer is filled. 3. Run a Normal cycle. 4. If HE appears again, switch the breaker off and stop using the dishwasher. 5. Call us to test the sensing circuit. Mention what the display showed when you call.

! Why to stop there

A repeat cycle cannot show whether the sensor or the wiring is giving the wrong reading.
We compare the reading to the actual tub temperature before changing anything.
A written quote precedes any work, and the repair has a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

HEHE questions

Does HE mean the water is not heating?

Not exactly. It says the temperature is being read incorrectly. The water may be fine, but the control cannot be sure, so it stops. We read the actual temperature against what the control believes.

What sets HE apart from HC1?

HC1 on DW80T models says the heater did not warm the water. HE is a sensing problem. They can look alike on the display, so we test both.

Is it fine to run the dishwasher meanwhile?

We suggest not. A control that cannot read temperature may not heat or protect the machine properly. If it keeps showing HE, leave the cycles alone until we test the sensing.
