E22: Difficulty in draining water during drying phase

Tests to be performed:
Is the condenser clean?
-(see fig.24)-
YES
Is the drain filter clean?
Is the drain system OK? (Drain hose and
domestic hydraulic circuit)-(fig.1)
Does the drain
pump function? (in
the diagnostic cycle,
select fill and
phase 2
drain) (noise
phase 8
from the pump).
YES
Is the hydraulic circuit of the pressure switch
efficient? (i.e. not obstructed)
Replace the pressure switch and restart the
diagnostic cycle to check for further alarms.
