About Panasonic Error Codes

Panasonic error codes cover washers in our database (22 total codes). The severity distribution includes 22 medium and 0 low codes. Panasonic machines use alphanumeric diagnostic codes displayed on the control panel. When an error appears, the machine typically stops mid-cycle and requires troubleshooting before resuming operation. Each code in the table below maps to a specific failure mode — sensor fault, valve failure, control-board issue, drum imbalance, drain blockage, heater circuit problem, or door-lock failure. Resolving these codes promptly is essential to keep a laundromat running and avoid revenue loss from out-of-service machines.

Service Guy AI maintains the Panasonic diagnostic database with troubleshooting steps, possible causes, required parts (with OEM part numbers where available), and skill-level guidance ranging from beginner attendant fixes to advanced electromechanical work that requires a factory-certified technician.

Most Common Panasonic Issues

  • Drain pump impeller jam (F02 variants)
  • Water inlet valve clogging (nF codes)
  • Door lock failure (dL codes)
  • Control board issues on newer models

How to Use This Panasonic Error Code Database

Locate your Panasonic error code in the table below and click it for a complete troubleshooting walkthrough. Codes are color-coded by severity — critical codes require immediate attention (the machine will typically lock the door and refuse to run), while medium and low codes allow continued operation but should be cleared before the issue escalates. For complex faults or when the displayed code isn't listed, run a Service Guy AI photo diagnosis — upload an image of the error display and the AI matches it against the full database including model-specific firmware variants.
