1 – Introduction
This document describes the procedures for performance of the testing cycles on the 3rd generation Electronic
Programmer for PL3 digit+programs free-standing 45cm dishwashers.
2 – Test cycle
2.1 – Cycle Access Procedure
Before recalling the test cycle, check that the dishwasher is in starting condition with the tank empty. To do this, simply
access the “Program Abort” procedure described in point 2.3.
To recall the test cycle, proceed as follows:
Program LEDs Option LEDs
T4
a) With the door closed, keep the Start/Pause key (T1) depressed. LED L1 starts flashing; keep the key
depressed for about 30 seconds, until LED L1 remains constantly on (beeper sounds).
b) Within 3”, release the Start/Stop key (T1) and press it again to confirm that you wish to perform the test cycle.

The message
If the procedure is not carried out correctly, the test program is not selected and the procedure has to be repeated from
point (a)
2.2) Exiting the test cycle
To exit the test cycle, simply switch the dishwasher off. This means that if the dishwasher is switched off during the test
cycle, all memory of it is lost and the “Access Procedure” has to be repeated to reactivate it.
2.3) Aborting the program
To abort the program and bring the appliance to a known starting status for performance of the test cycle, proceed as
follows:
a) With the door closed, keep the Start/Pause key (T1) depressed until the message
display. The appliance automatically starts the pump-out, after which the end of cycle message appears:
C0 appears on the display to confirm this operation.
P0 appears on the

2.4) Performing the test cycle
Phas
e
1)
AWAITING START OF TEST CYCLE:
The appliance has its door closed and is ready for performance of the test cycle
2)
START OF TEST
Press the Start/Pause (T1) key until the Start/Pause LED flashes. After a few
seconds the appliance starts to take in water (first with motor stopped, then with
motor running)
3)
DETERGENT DISPENSER HATCH OPENING
After the pressure switch signals full and the dishwasher is completely full, the
detergent dispenser is activated.
4)
HEATING
The appliance heats to 50°C.
During this phase, operation of the safety unit on the tray can be checked by
lifting the polystyrene float; when the float is raised, the drain pump should start
up.
NB: During this phase, pressing the Start/Pause key (T1) forces the cycle
on to the next phase
5)
WAIT FOR USER CONTROL
When the temperature of 50°C is reached, the appliance stops and beeps. The
regeneration solenoid is activated during this phase
To continue the test cycle the operator must press the Start/Pause key (T1)
6)
FINAL PUMP-OUT
After the program key has been pressed the appliance pumps out (or continues
to pump out if already in this phase) and simultaneously operates the
regeneration solenoid valve. After the pressure switch empty signal is supplied,
the drying fan starts up.
7)
END OF TEST CYCLE
At the end of the pump out cycle the appliance enters the end of test state.
Switch off the appliance, open the door and check that the detergent dispenser
hatch has opened.
N.B. If the door is opened during performance of the test cycle, when it is closed again the Start/Pause key must be
pressed to continue the cycle. However, this skips the phase of the cycle in progress before the door was
opened.

2.5) Checking operation of the display circuit board
a. Press the program selection key (T4) and check that the program changes (the program LEDs illuminate in
sequence); the display shows the duration of the program, which of course changes from program to program.
b. Checking operation of the delay timer option. Set a program other than Soak, press the “Delay timer” key (T2)
several times in succession and check that 1h, 2h, etc. appear on the display. Return to the delay timer off
condition by continuing to press the delay key (T2) until the program duration reappears on the display.
c. Checking the other options (where present). Set a program other than Soak, press the key of the option and
check that the relative light comes on. Press the key again and check that the light goes out.
GENERAL CHECKS TO BE MADE DURING THE CYCLE
1) Check for water leaks as described in I0 06
2) Check operation of the Salt and Rinse Aid warning lights (where present)
3) Operation of the top “wash” function (where present)
N.B.: The operating modes for these procedures are set in the appliance’s processing cycle (by T&M)
3) Alarms
The following is a list of the error messages which may appear on the display.
