36. (00100100) Phase 1 to 5 - Water Leak Fault
The Motor Controller has needed to top up the water level more than 4 times during agitate.
This is excessive as normally only one or two top ups are required to replace the air that has
escaped from a full load during agitate. The most likely cause is that Smartdrive is siphoning.
The other alternative is that Smartdrive has developed a leak.
Primary Source - Pump System
Action - Check the height of the drain hose outlet. 850mm min. 1200mm max.
Secondary Source - Mechanical
Action
1. Check pressure tube connection on outer bowl and Motor Controller.
2. Check that the drive shaft seals and the pump house seals have not developed a leak, by
looking through the front inspection cover.
Tertiary Source - Motor Controller. (Display Module Phase 1).
Action - Replace Motor Controller. (Display Module Phase 1).
37. (00100101) Phase 1 to 5 - Pump Block Error
While draining, the water level reading from the pressure transducer has not changed for over
3 minutes. There are four likely reasons for this fault. One is that the drain hose has been
squashed or kinked and the pump out rate has been dramatically reduced. The second
possibility is that the pump is partially or fully blocked. The third is that the pump is not
operating due to Motor Controller, wiring, or pump failure or thermal overload cut out. The
fourth is that the Motor Controller is not reading the water level correctly. This fault could also
appear if Smartdrive is pumping to an unusually high head of drain hose or into an extended
length of drain hose.
Primary Source - Pump Blocked
Action
1. Run pump and check flow rate from drain hose. This will identify whether the pump is fully
or partially blocked or is functioning OK.
2. Drain the product and inspect pump from the top of Smartdrive by removing the top deck
and inner bowl. Clear blockages if found. Check the pump hood is secured tightly. If this is
loose this can give poor pump performance.
3. Visually check that the drain hose has not been kinked. Check length of drain hose and try
to reduce length if excessively long.
4. Check for correct resistance of the pump. (NB. Pumps are fitted with a thermal cut-out
which will reset on cooling). If resistance is low replace pump. Check Pump Harness is
connected correctly to pump.
Secondary Source – Pressure Tube
Action - Check the pressure tube is not kinked and clear of water droplets. Clear tube and
reconnect when bowl is empty.
Tertiary Source - Motor Controller
Action - Replace Motor Controller.
NB. Consider fitting Pump Hood Kit (WM013). If 5kg Smartdrive fit splash guard to pump.
