Safety first: Do not open electrical enclosures without isolating power.

Review programming: Consult the Lowara manual and review all programmed speeds and schedules. Correct any overlaps or conflicts.
Check external control: If connected to a pool automation system, verify that external commands are not overriding the pump’s internal schedule.
Save settings: After programming, ensure settings are saved according to the manual to survive power outages.
Firmware reset: If behavior is erratic, perform a factory reset and reprogram.
When to call a pro: Persistent control anomalies may indicate a faulty keypad or control PCB requiring replacement.
