Specification of error signals of the PC washing machines

Rev.02, 13 February 2004

The electronic system has been equipped with the self-testing function of the washing machine to detect damages or incorrect operation of the

washing machine. The electronic controller of the washing machine signals that the error has been detected by pulsed “READY/END” diode. For the
“Comfort” washing machine, the error code is shown on the LED display by the letter E and the error number. For the “Optimum” washing machine, the
error code is shown on 4 diodes next to the function buttons. Since the number of signalling options on the diodes is much lower than on the display, in
the “Optimum” model part of similar errors has the same signals.

After cutting the power off, the washing machine remembers the most recent error, to delete the error from the memory (and operate the washing

machine further) the error signal needs to be reset by pressing the START/STOP button for about 3 seconds.

Note! Signal resetting does not mean that the error reason has been removed, but means only that information about error detecting has been

deleted from the controller memory! The error signal describes only the irregularity found but does not specify the damaged element! All signals shown
below may also occur if the wires or the electronic elements are damaged (which is not shown in each point below).

Note! Each error detected locks the door. The door may be unlocked only by resetting the error signal or switching the washing machine off

using the mains switch.

Direct cause

Action of the controller

Possible reasons for the defect

E01

No feedback signal from
the door lock

After 15 seconds, the E01 code is shown
and the washing programme is stopped.

Open door of the washing machine

- Damaged

lock

Door lock shifts the lock detector insufficiently

E11

No adjustment of the triac
of the door lock

After 2 seconds the E11 code is shown and
the washing programme is stopped.

Damaged printed board

E02

Time of water taking of
more than 2 minutes

After washing ends, the E02 error is shown.
Additional water taking is blocked above
the pressure control level.

Low water pressure

Supplying hose or valves are partly clogged

E05 D2,

No signal from the pressure The programme is stopped and the E05

No water supply

start of taking water

code is shown.

Very low water pressure

Damaged solenoid valve

Damaged pressure control

The direction-shift valve (of the washing
machine from AquaSpray) is locked in the “off”
position

E03

D2, D3

Time of pumping out of
more than 1.5 minutes

The next spinning after pumping out is
limited to 400 rpm, after the programme
ends the E03 code is shown.

The pump filter is partly clogged

The drain hose is partly clogged

E06 D2,

D3,

10 minutes after the start of
pumping out, there is no
signal of draining from the
pressure control.

The programme is stopped and the E06
code is shown.

- Blocked

pump

Clogged drain hose

The direction-shift valve is locked in the “on”
position

Damaged pressure control

E09 D1,

D3,

The washing machine has
detected too much foam
during the last spinning and
the foam has not been
removed.

The programme ends without spinning with
the error signal displayed.

The washing machine is operational, too much
detergent

E04

D3, D4

The pressure control sends
an “overflowing” signal

The programme is stopped, the pump is
switched on and the E04 code is shown. 1.5
minutes after the “empty tank” signal from
the pressure control, the pump is switched
off. If water is detected once again when
E04 is shown, the pump is switched on
again.

Solenoid valves are locked in the “open”
position

Great water pressure changes during a washing
cycle

The washing cycle starts with the water supply
closed; the water supply is opened during
washing

Damaged pressure control

E31

D1, D4

Closed temperature sensor. The programme is not stopped. After the

washing ends, the E31 error symbol is
shown.

Damaged temperature sensor

E32

D1, D4

Open temperature sensor.

The programme is not stopped, after the
washing ends, the E32 error symbol is
shown.

Damaged temperature sensor

E33

D1, D3

Waters temperature didn’t rise

Washing – machine doesn’t interrupt
program, after washing symbol E34 is
displayed

- Damaged

heater;

Washing – machines overloaded;

NTC sensor damaged

E34

D1, D3

Heating time exceeded

Washing – machine doesn’t interrupt
program, after washing symbol E34 is
displayed

Break in the heaters circuit – damage of heaters element,
bunch or controller.

E21

Locked motor: although
voltage is supplied there is
no signal from the
tachogenerator.

The programme is stopped and the E21
symbol is shown.

Damaged motor (tachogenerator, thermal switch
or wiring)

Removed motor junction

Open thermal switch as a result of motor
overheating

E08 D1,

D2,

D3, D4

Mains voltage outside the
range of 160-253V,
50/60Hz.

The E08 error is shown – the washing
cannot be stopped. After resetting, the error
(if the reason is still present) is detected
again.

Incorrect mains voltage

E22

Short circuit on the motor
triac – there is a signal from
the tachogenerator although
the motor is not powered.

The programme is stopped and the E22
code is shown.

Damaged electronic system (single cases may be
caused by putting in a very unbalanced load such a
blanket or a bathrobe).

E07

Signal (contacts open) from
the float detector – water
on the bottom of the
washing machine.

The programme is stopped and the E07
code is shown. The pump is switched on
(switched off 1.5 minutes after the “empty
tank” signal).

Water leakage from the tank or hoses

E42

Time to unlock the door
lock of more than 120
seconds

The error occurs at the end of washing, if
after washing ends, the door is not unlocked
within 2 minutes. The E42 code is shown
and does not allow another cycle to be
switched on without resetting the error
signal.

Damaged door lock

Door locked mechanically

E52

D1, D2

Incorrect data in EEPROM. The error occurs just after the washing

machine is switched on, if data from
EEPROM are incorrect.

Incorrect records in EEPROM;

Damaged EEPROM system.

Note:
E11 – means a code shown on the display;
D1, D2, D3, D4 – means diodes next to function buttons are on, with the D1 diode at the top.
