Flashing Error Lights
Dolphin (Maytronics) Robotic Pool Cleaner
Severity: ModerateWhat Does This Error Mean?
Flashing lights on a Dolphin robotic cleaner indicate specific errors. The pattern tells you what is wrong: drive motor, pump motor, or sensor issue. Check the manual for your model's specific light codes.
Affected Models
- Dolphin Nautilus CC Plus
- Dolphin Premier
- Dolphin Sigma
- Dolphin M600
- Most Maytronics Dolphin models
Common Causes
- Drive motor jammed — debris wrapped around the tracks
- Pump motor blocked — filter full or impeller jammed
- Power supply fault
- Cable tangled preventing the robot from moving
- Sensor detecting the robot is stuck
How to Fix It
-
Remove the robot from the pool and check for debris.
Hair, leaves, and string often wrap around the drive tracks or brushes. Remove all debris.
-
Clean or replace the filter bag/cartridge.
A full filter prevents the pump motor from working. Rinse the filter thoroughly or replace if worn.
-
Check the cable for tangles.
A tangled cable prevents the robot from navigating. Un-tangle the cable and let it float straight in the pool before restarting.
-
Check the power supply.
Make sure the power supply LED is solid green. Flashing or red on the power supply indicates a power issue.
