o
The tank resistor does not operate in the following cases:
•
Machine OFF.
• If the tank temperature condition is met (TT≥Set temp) .
•
If the tank level condition is not met (PT<PT1).
•
During automatic drainage or the running of a drainage programme with self-cleaning.
•
In the event of a tank probe error (see table of errors).
o
Depending on the heating configuration, the tank and boiler resistors may or may not operate together at
the same time
•
For the alternate heating type: The tank and boiler heating are alterate, i.e. the 2 resistors never
operate at the same time. If both are due to start, the boiler takes precedence over the tank.
•
For the simultaneous heating type: The tank and boiler heating may be simultaneous, both heaters
may operate together without problem.
9.6.9. SCREEN ON/OFF
When the dishwasher is switched off, none of the Led are lit. The message on the display shows the name of the
model, the date and the time.

The machine is switched on and off by pressing ON/OFF for one second . ON is lit whenever the machine is on.
When the machine is on, RG is active, as this is the general relay of the electrical installation.
In ON , the display shows the messages for each operating mode.
9.6.10. FILL AND PREPARATION
If the machine is empty and the user presses ON/OFF , the dishwasher will come on and the machine filling and
heating process is run automatically. This process is known as machine filling and only L1 (red LED) remains lit
with the message “FILL” on the display.
When the machine is switched on, if PC>=5 the rinse pump (BA) is activated until PC<5 + 5 seconds.
During the filling the procedure is as follows: VC is activated, waiting until PC gives the signal that the boiler is full.
In models with a water softener, EVR1 is activated with VC but is deactivated with a delay of 8 seconds to prevent
the water returning to the salt circuit.
On reaching the level, VC is deactivated, CC is activated (after a delay of 10 seconds to update the temperature).
CC remains active until TC reaches 65 ºC or the error “E5 FAULT IN BOILER HEATING” , is triggered, in which case
an error is given. BA is activated for 15 seconds.
Next the boiler is filled for the second time, BA is activated for 15 seconds when it is full and hot.
This sequence is repeated as often as necessary until PT (tank pressure switch) gives the tank full signal
(PT=PT3). This indicates that the machine is full and it goes from the filling stage to the preparation stage (TT=60
ºC and TC=65 ºC by default), and the boiler fills again and the water is heated to 82 ºC (programmable rinse
temperature). Similarly the tank water is heated to 60 ºC (programmable wash temperature).
L1 (red LED) remains lit until the programmed tank level is reached and TT<=(Setting -10), indicating that the
machine is not ready to run a cycle. In any case, if the defined level is reached, the user may run a cycle, in which
case WARNING A3 is given.
When the tank level is reached and TT>(Setting-10), L2 (green LED) is lit, indicating that the machine is now ready.
In addition, the display will show the tank temperature (wash Temp) and the selected wash programme (P1 by
