3C (Pump operation check) - This error indicates the dishwasher cannot verify proper pump operation. According to the service manual, this in most cases results from a faulty circulation pump or blocked water lines. Requires technician diagnosis; repairs take 60-90 minutes.

AP (Smartphone connection error) - Occurs when the dishwasher fails to establish connection with the SmartThings app. The official manual states this is caused by Wi-Fi signal interference or incorrect app settings. Users can resolve this in 15 minutes by resetting network connections.

PC (Zone wash function check) - Signifies a malfunction in the targeted washing zone system. The manual specifies this stems from either a defective zone wash valve or control board error. Professional repair required with an estimated parts cost of $85-$120.

Follow these steps sequentially when any error appears:

  1. Power Cycle - Unplug dishwasher for 90 seconds (official manual specifies minimum 60 seconds)
  2. Inspect Filters - Clean both mesh and coarse filters (located behind the lower spray arm)
  3. Check Connections - Verify water supply pressure exceeds 20 PSI and drain hose has no kinks
  4. Error Logging - Note exact error code and frequency of occurrence

The service manual states these steps resolve approximately 30% of error conditions without further intervention.

How do I reset error codes on my DW80R9950-SERIES?

Section titled “How do I reset error codes on my DW80R9950-SERIES?”

To clear error codes, press and hold the Delay Start and High Temp buttons simultaneously for 5 seconds (per service manual page 37). This performs a soft reset. For persistent errors, unplug the unit for 5 minutes.

The UUUU error indicates cycle sequence disruption. The manual identifies three potential causes: incorrect detergent usage (page 42), faulty water inlet valve (page 89), or control board timing error (page 112). Professional diagnosis is required.

The service manual explicitly states (page 15) that non-OEM parts can cause additional errors and void warranties. Samsung-approved replacement parts have specific part numbers beginning with “DA97-”.

Service manual estimates:

  • Pump replacements: 75 minutes
  • Control board swaps: 105 minutes
  • Sensor changes: 45 minutes These times include mandatory testing procedures.
