Drain the pump.
Disassemble the handle, unscrew the screws.
Disassemble the cover of the electrical part, unscrew the screws.
Push the switch lever and disassemble the cover of the float.
Remove the float, check if the material prevents the free flow and just in case proceed to cleaning.

11. TROUBLESHOOTING
Before taking any troubleshooting action, disconnect the pump from the power supply (i.e. remove the
plug from the socket). If there is any damage to the power cable or pump, any necessary repairs or
replacements must be performed by the manufacturer or his authorized customer support service, or
by an equally-qualified party, in order to prevent all risks.
