How To: Samsung Washer Vibration Sensor DC93-00278B

What the Vibration Sensor Does in a Samsung Washer

The vibration sensor, also called a balancing sensor, is a safety mechanism that detects when the washer tub becomes unbalanced. It is located on the bottom of the outer tub and has a wire that connects to the main control board.

This important part monitors vibration levels during high-speed spin cycles. Excessive vibration occurs when a heavy load becomes off-centered. Too much imbalance can damage components and make the washer “walk” across the floor.

To prevent this, the sensor communicates balance issues to the control board. When the vibration reaches a certain threshold, the sensor will automatically stop the spin cycle and initiate a recalibration. It causes the washer to display error codes like UE, 0E, or dE.

Diagnosing a Failing Samsung Washer Vibration Sensor

Here are the most common signs your Samsung washer has a defective vibration sensor that needs replacing:

  • The washer stops mid-cycle, usually during spinning
  • You get an unbalanced load error code but the tub seems balanced
  • Spinning problems happen intermittently even with normal loads
  • The washer seems to vibrate, shake, or “walk” excessively during spin cycles
  • You hear loud banging noises coming from the washer tub area

If any of these issues sound familiar, it’s highly likely the vibration sensor is malfunctioning and interrupting normal operation. Not replacing it will result in ongoing performance problems with your washer.

Materials and Tools Needed

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

  • Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
  • Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
  • Take your time and don’t rush while working to prevent accidents and personal injuries.
  • Work in a well-lit area so you can clearly see and access the interior parts.
  • Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
  • Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
  • Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
  • Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
  • Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
  • If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
  • Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
  • When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
