PE2
Samsung Washing Machine
Severity: ModerateWhat Does This Error Mean?
The PE2 error means your Samsung washer has a problem with the water level pressure sensor. This sensor tells the machine how much water is in the drum. When it malfunctions, the washer cannot control water fill properly and stops the cycle.
Affected Models
- WF45R6100AW
- WF50R8500AV
- WF45T6000AW
- WF42H5000AW
- Most Samsung front-load washers
Common Causes
- The pressure sensor hose is blocked, kinked, or disconnected
- Water or debris has entered the pressure sensor tube
- Faulty pressure sensor (also called water level sensor)
- Control board failing to communicate with the pressure sensor
- Excessive suds from too much detergent interfering with pressure readings
How to Fix It
-
Unplug the washer and turn off the water supply.
You will need to access the back or side panel to reach the pressure sensor hose.
-
Locate the pressure sensor — a small round component usually mounted on the side wall inside the machine.
A thin rubber or plastic hose connects the sensor to the drum area. Check your user manual for its exact location.
-
Inspect the pressure sensor hose for kinks, cracks, or blockages.
Gently blow through the hose to check for blockages. If it is clogged with detergent residue, rinse it with warm water.
-
Make sure the hose is securely connected at both ends.
A loose hose will cause false pressure readings. Push the ends firmly onto their connection points.
-
Reassemble, plug in, and run a test cycle.
If the PE2 error returns, the sensor is likely defective and needs professional replacement.
When to Call a Professional
If cleaning the pressure sensor hose does not fix the issue, the sensor itself may need replacement. This involves accessing the rear panel of the machine. A technician can test the sensor with a multimeter and replace it in under an hour. Expect repair costs of $100–$200.
Frequently Asked Questions
What does the pressure sensor do on a Samsung washer?
It measures how much water is in the drum. Think of it like a fuel gauge — it tells the machine when enough water has been added and when to stop filling. If it fails, the machine cannot manage water levels and will stop with an error.
Can using too much detergent cause the PE2 error?
Yes — excessive suds can interfere with the pressure sensor's readings. Too many bubbles in the drum can fool the sensor into thinking water levels are wrong. Always use the correct amount of HE (High Efficiency) detergent for Samsung washers.
Is PE2 different from PE on a Samsung washer?
Both relate to the pressure sensor. PE is the general pressure sensor fault code. PE2 typically indicates a more specific issue, often with the sensor's electrical signal or hose connection. Troubleshooting steps are the same — start with the hose, then the sensor.
