What Does Error Code PC Mean on a Samsung Dishwasher?

Pump/zone wash fault — distribution motor or pump circuit error.

PC fires when the control board cannot confirm the zone-wash distribution motor has reached its commanded position, or when it reads current draw suggesting a binding, corroded, or open pump/motor circuit. Unlike drain-related faults such as nE, PC points to the wash-side distribution valve and pump wiring rather than water level or drainage. A common root cause is long-term moisture corroding the connector at the pump assembly beneath the tub, mimicking a failed motor.

Models affected: Samsung dishwashers with zone/vario wash distribution systems, including models such as DW80R5060US, DW80K5050US, DW80B6060US, and DW80CG4051SR
What owners report: Owners commonly report PC appearing mid-cycle, sometimes after years of use, and a breaker power-cycle occasionally clears a one-off sense glitch. Where the code returns, many trace it to green corrosion on the under-tub pump connector rather than the motor itself, so inspecting that harness first is often the quick win.

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Distribution/vario motor stuck or failed 40% of cases
  2. 2
    Corroded connector or harness at the pump assembly 30% of cases

How to Fix Samsung Dishwasher Error Code PC

🔧🔧🔧 Advanced DIY Est. time: 1–3 hours
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Power cycle

    Switch off at the breaker for 5 minutes — a position-sense glitch can clear.

  2. 2

    Inspect connectors under the tub

    Tip the unit (water supply off, drained) and inspect the pump and distribution motor connectors for green corrosion; clean or repair the harness.

    ⚠️ Disconnect power at the breaker before working under the dishwasher.
  3. 3

    Replace the distribution motor

    If the valve doesn't rotate during a cycle, replace the distribution (zone wash) motor assembly.

Frequently Asked Questions

Can I keep using my Samsung Dishwasher when error PC appears? +
It is not advisable. The dishwasher may still power on, but running it while PC is active can worsen the pump fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes PC on a Samsung Dishwasher? +
Across reported Samsung dishwasher repairs, the most frequent is distribution/vario motor stuck or failed (40% of cases), corroded connector or harness at the pump assembly (30%), then debris jamming the distribution valve (20%). Check them in that order before replacing any parts.
PC keeps coming back after a reset — what should I check next? +
A reset only clears the stored PC fault; if it returns, the pump problem is still present. Move on to the physical checks — power cycle, then inspect connectors under the tub — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.
How much does it cost to fix Samsung Dishwasher error PC? +
A DIY repair typically runs $0–$80 in parts, versus $170–$330 for a professional service call, so handling it yourself saves around $170. Expect the work to take 1–3 hours.
Which Samsung Dishwasher models show error PC? +
PC is documented on Samsung dishwashers with zone/vario wash distribution systems, including models such as DW80R5060US, DW80K5050US, DW80B6060US, and DW80CG4051SR. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
