Maytronics DOLPHIN-M400 user manual

If the blue light on your Maytronics Dolphin M400 is flashing, it typically indicates one of the following issues:
1. Pool Cleaning Cycle: During a cleaning cycle, the blue light will flash, indicating that the robot is actively cleaning your pool. This is a normal operation and nothing to be concerned about.
2. Obstruction Detected: If the robot encounters an obstacle or gets stuck in a particular area, the blue light might flash. Check if there are any obstructions in the pool or tangled debris restricting the movement of the cleaner. Clearing the obstruction should resolve the issue.
3. Filter Full: If the filter cartridge is full of debris, the blue light might flash as a warning. In this case, you need to clean the filter and remove any accumulated debris to ensure the efficient operation of the cleaner.
4. Impeller Blockage: A flashing blue light may indicate that the impeller is blocked, preventing the robot from functioning correctly. Inspect the impeller area for any clogs or debris, and clear them if found.
5. Battery Low: If the battery charge is low, the blue light might flash to indicate that the robot needs to be placed on the charging station for recharging. Make sure to connect the power supply and allow the robot to charge fully before using it again.
If the issue persists or you have concerns, it is recommended to refer to the user manual or contact Maytronics customer support for further assistance.

To reset your Maytronics Dolphin M400 pool cleaner, follow these steps:
1. Make sure the pool cleaner is turned off and unplugged from the power source.

3. Locate the reset button on the power supply unit. It is usually a small pinhole button.
4. Use a small object, such as a paperclip or the end of a pen, to press and hold the reset button for about 5 seconds. You may need to apply a bit of pressure.
5. While still holding the reset button, plug the power supply unit back into a power source.
6. Continue holding the reset button for an additional 5 seconds, then release it.
7. The pool cleaner should now be reset and ready to use.
Note: You may need to reprogram your desired cleaning settings after resetting the unit. Please refer to your owner's manual for specific instructions on how to program your Dolphin M400 pool cleaner.

There could be a variety of reasons why your Dolphin M400 pool cleaner is not moving. Here are some possibilities:
1. Power supply: Ensure the cleaner is properly connected to a power source and that the power supply is functioning correctly. Check if there are any loose connections or if the power supply is damaged.
2. Clogged or dirty filter: A clogged or dirty filter can restrict water flow and prevent the cleaner from moving. Clean or replace the filters as necessary.
3. Debris obstruction: Check for any debris, such as leaves or large objects, that may be obstructing the cleaner's wheels or impeller. Remove any obstructions and ensure the cleaner has a clear path.
4. Damaged or tangled cables: Inspect the cables for any signs of damage or tangling. If they are damaged, they may need to be repaired or replaced. If they are tangled, untangle them to ensure free movement.
5. Mechanical issues: There could be mechanical issues with the cleaner's motor or internal components. In this case, it may be necessary to contact the manufacturer or a professional technician for repair or troubleshooting.
If you've checked these potential issues and the pool cleaner still does not move, it is recommended to contact the manufacturer's customer support for further assistance or to consult a professional pool cleaner technician.
