5. My Dolphin is not picking up dirt/debris, or it’s escaping out the top of the unit:
• Check your filters and the impeller to make sure they are clean. Remove any debris from the impeller area.
• Check the intake opening on the bottom side of the cleaner for any obstructions.
• Check that the rapid drain flap is in place. (The flap is a black rubber part located behind the rear roller brush
and is visible by turning the unit upside down).
• Perform an out-of-water self-test to check for a bad impeller. (Refer to Item #2 for out-of-water self-test).
6. My Dolphin gets stuck on my VGB main drain cover:
• Turn the pool pump o while the Dolphin is cleaning. The additional suction from the main drain can cause the
Dolphin to get stuck.
• If available on your model, open the My Dolphin App or Remote Control and select “Manual Drive” mode and
steer the Dolphin o the drain.
• For certain bottom-loading models, Maytronics oers a VGB replacement impeller cover that can provide extra
propulsion that will help propel the cleaner o the main drain cover. Call Maytronics Customer Service for
availability.
• There are several after-market, drain assist devices that can be attached to the main drain cover to prevent
the Dolphin from getting stuck. These devices include:
> Main Drain Clip-On – inexpensive clips that fit most 8” main drain covers.
> Zodiac Unibridge Suction Outlet Cover – Creates a surface for pool cleaners to travel over.
> Color Match Pool Fittings – VGB Drain Covers – VGB Certified; reduces pool cleaner hang ups.
7. When I remove my Dolphin from the pool, dirty water/debris escapes out the bottom:
• The filters are overfilling. Empty filters.
• The Non-Return Flaps leading into the filter area may have become clogged with dirt/sediment, or have an
object lodged in the opening, preventing the flap from closing and allowing dirty water and debris to escape.
Rinse and remove any visible dirt, debris or objects with a hose.
• If this does not restore the non-return flap to its normal closed position, check the spring of the non-return
flap to see if it is broken. If so, take your Dolphin to your local dealer for a replacement part or call Maytronics
Customer Service.
8. My Dolphin gets stuck in one part of the pool, or consistently misses part of my pool:
• Make sure there is enough cable in the pool to reach furthest points.
• Try placing the Dolphin in the pool from a dierent location.
• The filters may be dirty. Try running the cleaner without the bag or cartridge filters. If the cleaner climbs the
wall, thoroughly clean the filters before putting them back in the cleaner.
• Scrub the pool floor. Algae can be on the pool surface before it is visible, making it slippery for the plastic
brushes.
9. My Dolphin floats/won’t sink all the way to the bottom of the pool:
• When a Dolphin wants to float it is usually due to trapped air in the cleaner or the pool’s chemicals are out of
balance – either the pH or salinity. Refer to your owner’s manual for appropriate ranges.
• If your model has a filter bag, turn the Dolphin upside down in the water. While upside down, open the two
flaps on the bottom filter lid, and using your fingers, open the two slots where the debris goes in, and allow
any trapped air to be released. Periodically, wash the bag in a washing machine – Air dry.
