UI EE failure
Self-Clearing (No), Retry Count (0), Retry Delay (0 Seconds), User Reset (No)
This fault indicates that an error occurred in the memory area of the chip used to store User Interface
parameters when configuring the pump. For some reason, the software was unable to read the
values from memory.
Power down the motor. Press any
Speed
button to restart the pump. If the fault continues to occur

Motor Stalled
Self-Clearing (No), Retry Count (50), Retry Delay (12 Seconds), User Reset (Yes)
This fault indicates that the rotor is locked. When the software detects a locked rotor, the motor
automatically shuts down and restarts. The pump cycles through the shutdown/restart sequence the
number of times specified in the Retry Count to correct the fault condition.
A locked rotor may be caused by an accumulation of dirt or debris in or around the motor causing the
impeller to jam. Refer to the
Maintenance
section on
page 30
for steps you can take.
·
Always disconnect electrical power at the fuse box or circuit breaker panel before handling
electrical connections or performing maintenance on the motor. Allow the motor to come to a
complete stop and wait two (2) minutes. This allows the control bus capacitors to discharge
any residual voltage.
Press the
Start/Pause
button to clear the fault from the LCD display. The retry sequence will start
over. Then, press any
Speed
button to restart the motor. If the fault continues to occur after a
maintenance inspection, contact your pool professional or a qualified electrician for service.
