74. (01001010) Pressure Transducer Error
The pressure transducer frequency is out of range
Primary Source:
Action:
104. (01101000) See Fault Code 106
105. (01101001) Comms Error Time Out
These faults are reported when the Display Module detects an error in the communications
between the Display Module and the Motor Control Module. Can also occur when the
display is change with the power still on.
Primary Source:
Action:
Secondary Source: Motor Control Module.
Action:
106. (01101010) Display Module to Motor Control Module Communications Error
These faults are reported when the Display Module detects an error in the communications
between the Display Module and the Motor Control Module.
Primary Source:
Action:
Secondary Source: Motor Control Module.
Action:
107. (01101011) Motor Control Module Reset Error
The Display Module has detected that the Motor Control Module has reset when it should
not have. This can be due to a Motor Control Module supply disturbance or microprocessor
failure.
Primary Source:
Action:
108. (01101100) Comms CRC Error – See Fault Code 106
109. (01101101) AC Pump Triac Over Temperature
This fault occurs when the electronics have detected that the temperature of the pump
Triac has exceeded what would be expected under normal conditions. The most likely
cause of this is that the pump has gone low in resistance.
Primary Source:
Action:
Secondary Source: Motor Control Module.
Action:
110. (01101110) Motor Bridge Thermistor Open Circuit
The motor bridge thermistor has been detected as open circuit. This means that the Motor
Control Module can no longer monitor motor bridge temperatures. This suggests that the
motor bridge thermistor has been damaged or removed from the PCB.
Primary Source:
Action:
111. (01101111) Motor Bridge Thermistor Short Circuit
Similar to Fault Code 110, however instead of detecting an open circuit, the motor bridge
thermistor has been detected as being short circuit.
