Wayne Ovation dispenser error/ fault log format table for iGEM dispenser troubleshooting
Understanding Wayne Ovation error codes is essential for efficient iGEM dispenser troubleshooting. The error log format displayed on the dispenser screen (using codes like S21.xx or S22.xx) helps technicians quickly diagnose issues and reduce downtime.

Each log entry records key details such as error code, device number, nozzle, date, and filling count, allowing precise tracking of events. Knowing how to interpret Wayne Ovation fault codes ensures faster service and prevents costly mistakes during repairs.
When servicing your dispenser, it’s crucial to use the correct Wayne replacement parts to maintain safety, reliability, and compliance. We highly recommend consulting our Wayne error codes article and the official Wayne Ovation parts manual to identify the exact part numbers you need.
