A) I'm not able to disengage the filter head from the filter canister.
Assure that all the four silver metal lid fasteners are simultaneously wide open. The presence of foreign objects could have generated an anomalous friction. Take off the filter head by simultaneously pulling the appropriate handles (there could be the need of another person helping you). After that, proceed with filter gasket cleaning.
Important: The motor head could get stuck if you try to remove it by pulling one side only. Remove the filter head by pulling with both hands on the proper grip points.

B) I'm not able to close the four metal lid fasteners.
The filter head is not correctly oriented with respect to the filter body. Not all four metal lid fasteners are fully inside their seats. Assure that all the metal lid fasteners are simultaneously wide open before proceeding with filter head closing operation.

C) The pre-filter lid doesn't close
Check that pre-filter handles are properly aligned in the "lock" position

D) When removing the filter head from the unit, water comes out from the metal locking levers
In order to avoid water spills when cleaning, during normal operation, the filter unit is not completely full of water. It maintains an air chamber underneath the filter head. The water inside the system is at a level where it does not overflow. During the standard procedure for releasing and maintaining cartridges or AQUASTOP disengagement, the water level inside tends to rise somewhat. Wrong operations may cause water to gather inside the unit head and then spill. The cartridge cups also hold some water when they are removed during standard maintenance operation. This restores an appropriate water level.
In order to prevent water seepage, DO NOT:
- Release then re-engage the AQUASTOP or open the AQUASTOP valves repeatedly.

This sequence should never be performed more than 2 times without removing one of the cartridges or emptying the unit.
- Close the AQUASTOP valve, open one of the cartridges, close the cartridge and then open the AQUASTOP valve,

The whole sequence should not be perfomred more than 2 times consecutively.
- Remove one of the cartridges and pour the content of the cartridge cup back into the unit.
- Re-insert a cartridge without having previously emptied the cartridge cup of its contents.
- Re-insert a cartridge too rapidly. (splash effect)
- Remove one of the cartridges and then opening the AQUASTOP valve lever.

E) There is water under filter canister feet.

During filter cartridge maintenance, water has seeped into the gap between the motor base and the top shell and is siphoning between the filter canister layers.

A gasket (probably that of the filter canister) or the chemical cartridge is missing.
