I have a CalSpa 2200 electronical controller. This unit has two (2) pumps and one of the pumps just stopped working. I have done the basic troubleshooting and have isolated the problem to the fact that there is no power on Pump 1 Between the WHITE (Common) and the BLACK (Low Pump) or RED (High Pump) power wires/connection. (*Please refer to the table below)

The table below shows the voltage measurments that we observed between the various wires by selecting the pump settings on the control panel. The voltages for Pump 1 between Ground (Green) and Pump Low (Black) and Pum Hi (Red) are consistent with the working Pump 2. The problem is clearly between the Common (White) and Pump Low (Black) and Pum Hi (Red). The voltage reading is 0 Volts for Pump 1, but is 250 Volts for the working Pump 2.

Pump 2 Low
Ground to Common)  125 Volts
Ground to Black (Low)  125 Volts
Ground to Red (High)
Common to Black (Low)  250 Volts
Common to Red (High)

Pump 2 High
Ground to Common)  125 Volts
Ground to Black (Low)
Ground to Red (High) )  125 Volts
Common to Black (Low)
Common to Red (High)  250 Volts

Pump 1 Low
Ground to Common)  125 Volts
Ground to Black (Low)  125 Volts
Ground to Red (High)
Common to Black (Low)  0 Volts
Common to Red (High)

Pump 1 High
Ground to Common)  125 Volts
Ground to Black (Low)
Ground to Red (High) )  125 Volts
Common to Black (Low)
Common to Red (High)  0 Volts

Green Wire  GROUND
White Wire  COMMON
Black Wire  PUMP LOW
Red Wire  PUMP HIGH

Additional Information:
There are two (2) pump connectors on the control unit and one works perfectly. I have verified that Pump1 is working properly by temporarily plugging it into the receptical for Pump 2. I have bypassed the WHITE wire in the connector and STILL NO POWER, so the WHITE wire and the connector are fine.
