Make sure the ON/OFF button is turned ON. The electrical outlet the control unit is connected to is not supplying electrical power. Plug main power cord into another electrical outlet that is powered and ensure the green light flashes once. If the green indicator does not illuminate, contact your local Polaris service representative.

The filter is full or sirty and needs to be cleaned following the procedure Section 5.1, "Cleaning the Filter Canister".

NOTE: The cleaner is not designed to climb up to the waterline.

1. The filter is full or dirty and must be cleaned following the procedure Section 5.1 of the owner's manual, "Cleaning the Filter Canister".
2. Microscopic algae are causing the pool side to become slippery. Do a shock chlorination treatment and slightly reduce the pH. DO NOT leave the cleaner in the pool during this treatment.
3. Tires are worn and need to be replaced.

There is air in the appliance casing so you must submerge the cleaner following the procedure in Section 4.1 of the owner's manual, "Submerging the Cleaner".

The control unit needs to be reset or it is not properly connected. Submerge the cleaner and reset the supply by:

1. Unplug the main power cord from the electrical receptacle.
2. Disconnect the floating cable connector from the control unit and then reconnect it following the procedures in Section 3.3, "Electrical Connection".
3. Plug the main cord in the electrical receptacle and check if the green indicator light illuminates.
4. Press the ON/OFF button. If the green indicator does not illuminate or flashes, contact your local Polaris service representative.

The cleaner is too heavy. Contact your reseller to obtain a polystyrene floater to install under the cover plate.

Remove debris from the stirrup and verify that it pivots freely. If the roller is worn, replace as necessary. Remove the polystyrene floater. Unscrew the cleaner cover plate and remove the polystyrene floater from inside the cover plate. Replace the cover and resubmerge the cleaner.
