Samsung Dishwasher Error Code PC

DIY checks firstReviewed November 2026Checked against manufacturer documentation
What this code means
PC: Zone Wash / dividing valve error: the valve that directs water between zones is not working

The valve that sends wash water to the selected zone or half of the machine has a fault, so cycles that use Zone Wash or Half Load will not run properly. A restart is worth one try; beyond that it is a valve or control problem for a technician.

Common causes

  1. Dividing (diverter) valve is defective
  2. Valve motor not moving or position feedback failing
  3. Wiring fault between the valve and the control board
  4. Main control board fault

What to check, in order

Safety first. Switch the dishwasher off and unplug it (or turn off its breaker) before checking hoses or filters. Expect water in the bottom of the tub and around the filter; keep a tray and towel ready. If you are not comfortable with any step, stop and call a technician.
  1. Turn the dishwasher off for at least 30 seconds and then back on.
  2. Deselect Zone Wash or Half Load and try a plain Normal cycle with a normal load.
  3. If the code only appears when a zone option is selected, avoid that option until the valve is repaired.
  4. Book service if the code returns, since the valve sits inside the machine.

Clear the code and test

  1. Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
  2. Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
  3. Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
  4. If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.

When to call a professional

Most cases are solved by the checks above. Book a technician if any of these apply:

  • The code comes back after you have run the checks and a test cycle.
  • You smell burning, see sparks or scorch marks, or the breaker trips.
  • Water is leaking and you cannot stop it at the tap.
  • The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.

When you call, give the brand, the code PC, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
