Measure VCC 5V between Pin 1
(GDD) and Pin 4 (VCC)
The pump V35 is defective. Check if the pump V35 connections
are properly inserted (CA-008 cable).
Check if the Cable CA-008 is not
damaged resulting to a short-circuit

Measure the level of the cleaning
liquid on the dispenser.
To check that the liquid is extracted
from the cartridge during the suction
cleaning process, make a small mark
on the cartridge at the current liquid
level. After performing a suction
cleaning session, check that the
liquid level has dropped during the
process. Otherwise, check the
reasons described down below.
