What Does the PC Code Mean?

PC fires when the pressure sensor sends a reading outside the expected range during the fill or wash phase. This sensor measures water level by detecting air pressure in a sealed tube connected to the tub. A kinked, blocked, or disconnected tube produces the same symptom as a failed sensor.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Pressure sensor air tube kinked, blocked, or disconnected40%
Pressure sensor DD96-01018A failed24%
Mineral scale inside sensor housing affecting readings14%
Control board sensor input circuit fault12%
Connector pins corroded on sensor wiring harness10%

Symptoms You May Notice

  • PC code at start of fill cycle
  • Machine fills without stopping at correct level
  • Machine does not fill at all - PC code triggered instead
  • Water level erratic across different cycles

Can you reset a Samsung dishwasher to clear the PC code?

Hold Start/Cancel for 3 seconds to clear PC. Code will return if the sensor or air tube issue has not been resolved.

Frequently Asked Questions

What is the difference between PC and 9E on a Samsung dishwasher?
Both indicate a pressure/water level sensor circuit fault and use the same part (DD96-01018A). PC tends to appear on specific model variants; 9E is more common across the lineup. The repair steps are essentially the same.
Where is the pressure sensor on a Samsung dishwasher?
It is located behind the lower front panel near the sump area. Remove the lower kick panel by unscrewing 2-3 screws and look for a small disc-shaped sensor with a thin plastic tube running toward the tub.
