The 39E error on your Samsung Washer means the control board has detected a communication failure between the main control board and the water valve or motor assembly. This usually points to a wiring or connector issue rather than a major mechanical fault, and many owners can check the basics before calling for service.

Error code 39E
Meaning Communication error between the main control board and a connected component (commonly the water valve or drive motor)
Severity Medium — the washer will usually stop mid-cycle but is not dangerous to leave until you can check it
Time to fix 15–40 minutes
Tools needed Phillips screwdriver, multimeter (optional)

What the 39E error means

The 39E code is triggered when the washer’s main control board sends a signal to a component, such as the water inlet valve or motor, and does not get the expected response back. This can happen because of a loose connector, a damaged wire, or a fault inside the component itself. It is similar in nature to other Samsung communication errors, such as the codes covered in our guide to the Samsung Washer SE Error Code: Causes and Fixes.

Common causes

  • Loose or disconnected wiring harness at the water valve or motor
  • Corroded or damaged connector pins from moisture exposure
  • Faulty water inlet valve that is not responding to control signals
  • Main control board fault or failed relay
  • Vibration during a wash cycle causing a connector to shake loose
  • Power surge or brief power interruption during operation

How to fix the 39E error

  1. Power cycle the washer: Unplug the washer for 60 seconds, then plug it back in and restart the cycle. This clears many temporary communication errors.
  2. Check the wiring harness: With the washer unplugged, remove the back or top panel and inspect the wiring to the water valve and motor for loose or disconnected plugs.
  3. Inspect connectors for damage: Look for corrosion, melted plastic, or bent pins on the connectors, and reseat them firmly if they look intact.
  4. Test the water inlet valve: Use a multimeter to check the valve coil for continuity; replace the valve if it reads open or shorted.
  5. Inspect the main control board: Look for burnt spots, bulging capacitors, or discoloured relays, which indicate the board needs replacing.
  6. Call a qualified technician: If the error persists after checking connections and components, the control board itself likely needs professional replacement.

FAQ

Can I keep using the washer after a 39E error?
You can try restarting a cycle, but if the error repeats, continued use may leave laundry unfinished or cause the machine to stop mid-cycle again.

Does a power cut cause the 39E error?
Yes, a brief power interruption during a cycle can sometimes trigger a false communication error that clears after a power cycle.

Is the 39E error covered by warranty?
If your washer is still under manufacturer warranty, a control board or valve replacement related to this error is typically covered — check with Samsung support first.
