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

3minutes. 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.
