The Motor Controller has recorded a water level of empty while it is agitating. The water level
must have been greater than empty for Smartdrive the enter the agitate mode initially. The most
likely cause of this fault is that the pressure transducer hose has been severed or fallen
off during agitate. Alternatively the pressure transducer may be faulty.
Primary Source - Mechanical
Action - Check that the pressure tube is intact and has not been cut.
Secondary Source - Motor Controller. (Display Module Phase 1).
Action - Replace the Motor Controller. (Display Module Phase 1).
39. (00100111) Phase 1 to 5 – Tap or Pressure Sensor Tube Fault
During fill, the Display module has not registered a change in the water level reading for a
certain length of time. It has then carried out a bowl check and found that the bowl is floating
although the water level reading is below bowl float level . The probable cause of this fault is
that the pressure tube has become blocked or kinked or has fallen off completely.
Alternatively the pressure transducer may be faulty.
Primary Source - Mechanical
Action - Check that the pressure tube is intact and not blocked with water, dirt or kinked.
Secondary Source - Motor Controller. (Display Module Phase 1).
Action - Replace Motor Controller. (Display Module Phase 1).
40. (00101000) Phase 1 to 5 - Bowl Dis-Engaged Fault
While carrying out a bowl check, the Display module has found that the bowl is not engaged
even though the pressure sensor indicates that the bowl is empty. The Motor Controller
continues to check for 2 minutes after which time the display this fault. If restart is on this
fault can take up to 4 hours to diagnose. The first two areas to check are the clutch and the
pressure tube. If these two appear correct, then the fault could be in the pressure transducer in
the Motor Controller.
Primary Source - Suds
Action - Too many suds, too much detergent has been used. Restart product when suds have
disappeared, or select a deep rinse option.
Secondary Source - Mechanical
Action
1. Check that there are no clothes or other foreign objects preventing the clutch from re-
engaging.
2. Next check that the pressure tube has not come off and that it is not kinked.
Tertiary Source - Motor Controller. (Display Module Phase 1).
Action - Replace Motor Controller (Display Module Phase 1), if the above check out without
fault.
