E21: Drain difficulty
E21
Maximum drain time exceeded (measured for every cycle phase)
Clean the filter and repeat the diagnostic cycle
to check for any further alarms.
Is the drain filter clean?
Disconnect and check the drain system
and repeat the diagnostic cycle to check
for any further alarms.
Is the drain system ok?
(drain pipe and water system of the home)
-(Fig.1)-
Is the drain pump
working?
(in the diagnostic
cycle, select
phase 2 fill and
phase 8 drain)
(noise from the
pump)
Is the resistance
measurement of the
pump approximately
155÷182 Ω? (Measure
it directly on the
connector on the board
side between J5-4 and
J5-5) –(Fig. 4)-
Replace the pump
and repeat the
diagnostic cycle to
check for any
further alarms.
Is the resistance
measurement of the
pump approximately
155÷182 Ω?

on the pump)
-(see Fig.5)-
Check/replace the wiring and repeat the
diagnostic cycle to check for any further alarms.
Is the pump rotor
mechanically
blocked or broken?
Is the pressure switch's water circuit efficient?
(no clogging)
Replace the circuit board and repeat the
diagnostic cycle to check for any further alarms.
Repair the water circuit of the pressure switch
and repeat the diagnostic cycle to check for any
further alarms.
