The 23E error on your Samsung Washer means the control board has lost communication with the water level (pressure) sensor. This usually points to a loose wiring connection or a faulty sensor rather than a serious mechanical fault, and it can often be fixed at home.

Error code 23E
Meaning Communication fault between the main control board and the water level/pressure sensor
Severity Medium — the washer will usually pause or refuse to start a cycle until resolved
Time to fix 15–40 minutes
Tools needed Phillips screwdriver, multimeter (optional, for testing)

What the 23E error means

Samsung washers use a pressure sensor to monitor how much water is in the drum during a wash cycle. The 23E code appears when the main control board cannot get a proper signal from this sensor, either because the connection is broken or the sensor itself has failed. It is similar in nature to other Samsung communication faults such as the Samsung Washer SE Error Code, where a signal between components is interrupted.

In most cases the washer will stop mid-cycle or refuse to fill with water once this error triggers, as a safety measure to avoid overfilling or underfilling the drum.

Common causes

  • Loose or disconnected wiring harness at the pressure sensor
  • A damaged or pinched wire caused by vibration during spin cycles
  • Faulty water level (pressure) sensor
  • Moisture or corrosion on the sensor connector pins
  • A failing main control board
  • Blocked or kinked pressure hose leading to the sensor

How to fix the 23E error

  1. Power down and unplug the washer — Always disconnect power before opening any panels to avoid electric shock.
  2. Locate the pressure sensor — This is usually found behind the top or rear control panel, connected to a small air hose running from the tub.
  3. Inspect the wiring connector — Check for loose, corroded, or disconnected pins and reseat the connector firmly.
  4. Check the pressure hose — Make sure it is not kinked, cracked, or blocked, as this can affect sensor readings.
  5. Test the sensor with a multimeter — If you’re comfortable doing so, check for continuity; a sensor with no reading likely needs replacing.
  6. Restart the washer — Plug it back in and run a short test cycle to confirm the 23E code has cleared.

FAQ

Can I keep using my washer if I see the 23E error?
It’s best not to. The washer may not fill or drain correctly, which can lead to poor wash results or water damage.

Is the 23E error expensive to fix?
Usually not — most cases are resolved by reseating a wire or replacing an inexpensive pressure sensor, similar to fixes for the Samsung Washer DE Error Code.

Do I need a technician for this repair?
Basic checks like inspecting wiring are DIY-friendly, but if the main control board is faulty, professional help is recommended, much like with the Samsung Washer LE Error Code.
