What does Bell & Gossett E01 mean?

E01 indicates the e-90E Smart Pump's internal communication link between its control board and drive module has been lost. The pump cannot coordinate motor operation without this link and will shut down immediately. This is a locking error that requires a manual restart after power cycling.

What does Bell & Gossett E02 mean?

E02 signals a motor overload condition on the e-90E Smart Pump. The current drawn by the motor has exceeded the drive's protection threshold, forcing a shutdown to prevent winding damage. This is a locking error that stops the pump until power is cycled and the root cause is resolved.

What does Bell & Gossett E04 mean?

E04 indicates the e-90E pump motor rotor is blocked or has lost synchronism with the drive. The motor attempted to start or run but the rotor could not rotate freely, causing the drive to detect a stall condition and shut down to prevent overheating and damage.
