Samsung Dishwasher Error Code PC

PC indicates a distributor motor position error. The dishwasher's control board detected that the distributor motor failed to reach its required position within 40 seconds, and this happened 5 times during the wash cycle. When this error occurs, the dishwasher skips the drying stage. The problem is centered on the distributor motor and its cam positioning mechanism.

The dishwasher may still run parts of the cycle when the PC error appears, but it will skip the drying stage and water distribution may be compromised. Dishes are unlikely to be cleaned properly in all zones. Continuing to run the unit without addressing the fault is not recommended, as repeated strain on a failing motor can lead to further damage to the distributor assembly or control board.

Repair costs vary depending on whether the issue is a wiring connection, cam alignment, or a full motor replacement. A distributor motor part alone can range from roughly $40 to $120 depending on the specific model. If a technician is needed, labor costs typically add $80 to $200 on top of parts. Clearing an obstruction or reseating a connector yourself would cost little to nothing beyond your time.

Some causes of the PC error are DIY-friendly. Checking for debris blocking the distributor assembly and inspecting the wiring connectors to the distributor motor are reasonable first steps for someone comfortable working on appliances. If the motor itself or the cam needs replacement, the repair requires disassembling part of the dishwasher interior and is moderately complex. If you are not confident working with appliance wiring and components, a technician is recommended.

A reset may temporarily clear the PC error code, but the fault will return if the underlying problem with the distributor motor or cam is not resolved. Because the error requires the mismatch to occur 5 times in a single cycle, the control board is detecting a genuine, recurring mechanical or electrical failure rather than a one-time communication glitch. Resetting without repairing the root cause is not a lasting solution.
