How to Fix Error HE — Step by Step

  1. 1

    Step 1: Power Cycle the Washing Machine

    Unplug the washing machine from the power outlet to reset it. Wait for 30 seconds to ensure any residual power is drained. Plug the machine back in and check if the error code HE disappears. If it does, proceed to the next step. If not, continue with the troubleshooting process.

  2. 2

    Step 2: Check the Water Heater Thermostat

    Locate the water heater thermostat, usually found on the side or top of the machine. Use a multimeter to measure the resistance across the thermostat terminals. A normal reading should be around 10-15 kΩ. If the reading is significantly lower (less than 5 kΩ) or higher (more than 25 kΩ), the thermostat may be faulty. Replace it with a new one if necessary.

  3. 3

    Step 3: Inspect the Water Heater Element

    Look for the water heater element, usually a coil or heating rod, inside the machine. Check for signs of damage, such as corrosion, rust, or excessive wear. If you find any damage, replace the element with a new one.

    Step 4: Check the Machine's Temperature Sensor

    Locate the temperature sensor, usually a small probe or thermistor, attached to the machine's tub or water inlet. Use a multimeter to measure the sensor's resistance. A normal reading should be around 10-15 kΩ. If the reading is significantly lower (less than 5 kΩ) or higher (more than 25 kΩ), the sensor may be faulty. Replace it with a new one if necessary.

  5. 5

    Step 5: Check for Blockages or Debris

    Inspect the machine's drain pump filter and check for any blockages or debris. Clean or replace the filter if necessary. Also, ensure the machine's tub and water inlet are clear of any obstructions.

  6. 6

    Step 6: Run a Diagnostic Test

    Consult your washing machine's user manual for instructions on running a diagnostic test. This will help identify any underlying issues with the machine's water heating system.

When to Call a Professional

If safety is a concern at any point during the repair, or if the issue persists after trying the above steps, get a professional assessment before attempting further repairs. Professional diagnosis can save you from replacing parts that are actually fine.

Field note: HE on a Samsung Washing Machine is a specific circuit complaint, not a reason to start with the most expensive part. Read when the code appears (start, fill, heat, drain, or idle). That timing is the diagnosis. Power-cycle for 60 seconds, then test the component named in the meaning — not a generic ‘control board kit.‘

What this code is not

  • Not a universal ‘replace the main board’ code.
  • Not diagnosed by watching one YouTube video for a different brand.
  • Match the part to when HE appears in the cycle, not to the most expensive SKU on the listing.
