Troubleshooting
TrueSTEAM has internal system diagnostics that monitor operation, maintenance schedules, and faults. If a
system fault is detected, TrueSTEAM will attempt to recover up to ve times in a 24-hour period.
• If TrueSTEAM is unable to recover by itself within 24 hours, the red Service light blinks in a series that
indicates the fault detected.
• Refer to the table below for the fault indicated, along with the steps to x TrueSTEAM.
• Press and hold the Go button until the Service light turns off.
