Samsung Dishwasher 9E Error Code: Water Level Sensor Fault

Quick Answer

Samsung 9E error code indicates a water level or pressure sensor fault. The sensor DD96-01018A monitors water level via air pressure in a small tube connected to the tub. A blocked or kinked air tube causes the same symptom as a failed sensor.

What Does the 9E Code Mean?

9E fires when the pressure sensor reads a value that does not correspond to any valid water level. This can be a dirty air tube, a sensor with scaled-up contacts, or an actual sensor failure. It is occasionally caused by a control board fault if the sensor tests in-spec.

Frequently Asked Questions

What does 9E mean on a Samsung dishwasher?

9E means the water level pressure sensor reported an out-of-range value. It is most often caused by a blocked air tube feeding the sensor or the sensor itself failing.

Is 9E the same as PC on Samsung dishwashers?

Both involve the pressure sensor circuit and use the same part DD96-01018A. They can appear on different model variants and slightly different sensor configurations. The diagnosis steps are nearly identical.
