## Discrepancy

LAV ISSUE, FLIGHT DIVERTED.  CREW COMMENTS:  ALL LAVS SHOW FULL WILL NOT FLUSH SAMC TEXT:  BITE TEST THE CONTROLLER AND IF IT FAULTS THE 41MG SENSOR, THEN REMOVE AND CLEAN THE LIQUID LEVEL SENSOR (CAREFULLY) TO REACTIVATE THE LAVATORY FLUSH SYSTEM.  SVC LAVS OPS OK LIQUID LEVEL GOOD.  SVC'D LAVS, OPS OKAY.  LIQUID LEVEL GOOD.
