Gen 3: Run Flow Meter Diagnostic

  • MAINTENANCE Menu, FL tst
  • Press and hold Green ► button for 5 secs.  Unit will open inlet valve and water will flow for 6 seconds.

One of four results will be displayed.

  • OK:  Flow is normal and flow meter is OK
  • Low:  Flow is low and flow meter is OK
  • High:  Flow is higher than normal and flow meter is OK

A Fail result means either that the flow meter is fouled with sediment and must be cleaned (usual) or has failed and must be replaced.
