10. My Dolphin’s “Full Bag/Cartridge Indicator” light comes on when the bag/cartridge is not full:
• This usually occurs when the impeller cannot spin fast enough due to dirty or clogged filters. Inspect the
impeller for debris and remove; clean the filters. Restart the cleaner; press and hold the reset button until the
light goes o (approximately 5 – 20 seconds).
• If light still does not go o, take your Dolphin to your local dealer or call Maytronics Customer Service.
• After resetting the full filter indicator light, run the unit without filters, see if light comes back on. If so, it may
be time to replace the filters.
11. My Dolphin is “popping a wheelie” or lifting; Does not make contact with the floor:
• Models with a single roller brush will “pop wheelies” when changing directions – this is normal.
• After turning, if the Dolphin does not return to the floor, check that the filters are not dirty or clogged.
(Although filters may look clean, small particulates can dry in the filter material and clog the pores).
• Make sure the filters, cartridges or bag are properly installed – snug, with no visible gaps and filter panels are
snapped securely in place.
• If your unit has a filter bag – make sure the elastic of the bag is snug against the bottom lid and that it is over
the plastic lip on the lid and no gaps are visible.
• Make sure you allow the foam climbing rings to become fully saturated before starting your cycle – usually this
takes 10-20 minutes.
> If these rings are not allowed to become absorbent, they can remain hard and sti. This can prevent
good suction and keep the brushes from contacting the pool’s surface.
12. My Dolphin’s cable is twisting or kinking:
• Only place as much cable in the pool as is needed to reach the far corners of the pool. Loosely coil excess
cable on the side of your pool.
• Periodically, straighten out cable and allow it to rest in the sun for several hours, then roll up loosely.
• If you Dolphin has floats on the handle, try pushing in the float on the non-cable side.
13. My Dolphin’s filters are torn or damaged:
• Please call Maytronics Customer Service along with your Serial Number for a replacement part number. Parts
are available through local Maytronics dealers or our approved internet retailers.
14. MyDolphin App is giving an error message; Unable to use the App
• The initial connection to the Dolphin using the app needs to be completed when the smartphone is connected
to the internet (by WIFI, 3G or 4G). If more than one Dolphin appears on the pairing screen, you need to
identify the correct Dolphin according to the Serial Number and not by its position on the pairing screen.
• Before connecting to the Dolphin for the first time, turn on the Dolphin for one minute. While the app is
connected to the Dolphin, the buttons on the Power Supply Unit (PSU) are in disable mode. In many cases,
restarting the app will solve the issue.

• If your Dolphin App is displaying an error code at the top of the screen (1 - 23), please contact your local Dolphin
dealer for diagnosis and repair. If you purchased an internet model, please call Maytronics with your Dolphin’s
serial number and the error code displayed for assistance with corrective actions to take.
