Dishwasher displays PE and may not fill or may stop unexpectedly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty pressure sensor, Blocked pressure hose, Loose sensor connector, Defective main PCB

Safety: Turn off power and water before removing side panels.

Locate pressure sensor: On many Samsung dishwashers, the pressure sensor is mounted on the side of the tub with a small hose leading to the sump.
Inspect hose: Remove the hose and blow through it to ensure it is clear. Clean any sludge or debris.
Check electrical connection: Ensure the sensor’s plug is fully seated and free of corrosion.
Replace sensor: If PE persists, replace the pressure sensor with an OEM Samsung part. If the error still remains, the main PCB may be at fault.
