Samsung Dishwasher Error Code PE

The PE code on a Samsung dishwasher indicates a half load or distributor motor error. The control board detected that the synchronous distributor motor did not reach its correct position within the required time: 2 minutes during normal operation, 1 minute in test mode, or 3 minutes during a cleaning cycle. The distributor motor controls water flow direction between the upper and lower spray arms, and a micro switch confirms its position. When that confirmation does not arrive in time, the PE fault is triggered.

A reset may temporarily clear the PE code, but if the underlying problem with the distributor motor or micro switch is not corrected, the error will return during the next wash cycle. Resetting is useful for ruling out a one-time electronic glitch, but a recurring PE code requires physical inspection and repair of the motor, switch, or wiring.

If the fix involves only reseating loose connectors, there is no parts cost and minimal labor time. Replacing a faulty micro switch typically costs in the range of $10 to $40 for the part, while a replacement distributor motor can range from $40 to $120 or more depending on the model. Professional labor to diagnose and complete the repair may add $80 to $200 depending on your location and service provider.

Start by checking the wiring connectors at the distributor motor and the micro switch, as loose or corroded connections are the most common cause. Unplug the dishwasher, locate both components, and firmly reseat each connector. If the connections are secure, the micro switch and distributor motor should each be tested to determine which has failed and needs replacement.

The dishwasher will typically halt the wash cycle when the PE error is active, so it will not complete a normal wash. Attempting to run cycles repeatedly without addressing the fault is not recommended, as it can place additional strain on the motor and related components. It is best to diagnose and repair the issue before resuming regular use.
