11. (00001011) Phase 1 to 5 - Pressure Sensor Fault
While measuring the water level the Motor Controller has detected a negative pressure.
Reconnecting the pressure tube to the pressure sensor while the bowl contains water can cause
this.
Primary Source – Pressure Tube.
Action - Check bowl is fully pumped out. Remove pressure tube from pressure sensor, clear
pressure tube of any water and reconnect tube.
Secondary Source - Motor Controller. (Display Module Phase 1).
Action - Replace the Motor Controller. (Display Module Phase 1).
12. (00001100) Phase 1 to 5 - Flood Protection Error
The Motor Controller has found the water level to be above the flood level and tried to pump
the excess water out. Either the water valves are stuck on and are letting water in at a flow rate
that is higher than the pump can handle or the pump is blocked and can't remove the excess
water.
Primary Source - Water Valves
Action - If the water valves are on continuously, check that the water valves turn off
mechanically ( remove power from Smartdrive ).
Secondary Source - Pump System
Action - Check pump for blockage and hose for correct height and kinking.
Tertiary Source - Motor Controller. (Display Module Phase 1).
Action - If water valves are being driven on electrically, replace Motor Controller. (Display
Module Phase 1).
13. (00001101) Phase 1 – Pump Fault
The Display Module has detected that the pump is on when it should be off.
Action
1. The pump is fitted with a thermal cut out device. Check if this device has been activated. If
it has wait until pump cools down before restarting. Check for any pump blockage and
check condition of pump i.e. pump seizure.
2. Check for open circuit pump windings. Check the resistance of the pump.
3. Check the pump harness or the connectors for an open circuit.
4. Replace Display Module.
