Cause 2: Only in the early production, E15 could be shown incorrectly
even if
the NTC wash sensor is open or shorted.
Before inputting the defect to the
Electric Module check the appropriate tests are carried out on the NTC
sensor which is integrated on the wash heater.
E17

the ohmic value on the Tacho (Also see E07)
also
check if the magnet is present

Visually check the cuore Electric
Module (tracks burned, water traces etc.)
IMPORTANT: in case of water traces appropriate controls are required on the
entire washing machine's hydraulic circuit.
E20
Cause 1: Difficult reading the water level: potentially defective APS Pressostat

drainage failure; as a foreign body may be present in the drain pump impeller,
clogged filter, plumbing partially obstructed,
bent drain tube. Generally,
before replacing the APS device it is better check that the appliance is draining
correctly.
E21
Unable to read water level: Check wiring and connection on the APS Pressostat
or Cuore Electric Module. Defective APS Pressostat.
E22
Troubles with water heating: Wiring or Water Heater or “Cuore" Electric
Module are defective.
