Operation sequence:
•
Water inlet solenoid opens.
•
Open circuit on Low Water Level Sensor after 15 minutes.
•
Open circuit on High Water Level Sensor after 15 minutes.
•
Lockout forced (error displayed at Networker).
•
Water inlet solenoid closes.
•
20 minutes delay till ServoSeal closes and drain valve opens.
•
ServoSeal closes and drain valve opens (20 seconds).
•
WashWaitTime period starts (45 seconds).
•
Water inlet solenoid opens for 30 seconds (WashTime).
•
WashWaitTime period starts (45 seconds).
If both the Low and High Water Level Sensors have
failed short circuit
, then the
Low Water Level Sensor failure will be forced after 120 minutes of pump operation.
Error 40 code will be displayed, alternating with this drain error, when and if the water
inlet solenoid is open.
Because both the Low and the High Water Level Sensors are closed circuit, the water
inlet solenoid will remain closed.
As the water inlet solenoid will not open, the coolers tank will not fill, and/or any water
that was present will eventually evaporate.
This condition will not harm the pump, but will result in poor and inadequate cooling
performance.
To rectify this condition, refer to Service Checks on page 73.
