SERVICE MANUAL

9. SPECIAL FEATURES

9.1 RESIN REGENERATION CYCLE

TANK

BOILER

The regeneration cycle is activated by pressing the button shown in the figure, for at least 5 seconds.

For this key to be enabled parameter rE

( in family

CFG

) must be set to 1

.

At this point you can enter the number of wash cycles that can be performed after each regeneration: parameter rCY

in the counters family

Cnt

. If

rCY

is set to zero the counter is disabled, otherwise after the preset number of cycles the message rEG

is displayed to confirm that regeneration is possible (this is an information-only message with no effect on operation of the appliance, so you can continue to use the dishwasher). The message is cleared when the regeneration cycle is terminated.

The number of regeneration cycles performed can be checked by consulting the parameter nrE

in the

Cnt

family of counters.

When there are just 15 cycles remaining before the next regeneration cycle, at the end of the wash cycle the display shows the message

End followed by

15

, at the end of the next wash cycle the display shows

End

and

14

, and so forth, i.e. the display informs the user of the number of wash cycles still available before resin regeneration is required.

Before starting the regeneration cycle remove the siphon spillway.

CAUTION: if the regeneration cycle is accidentally started, it can be switched off by pressing the button shown in the figure, for at least 5 seconds.

The hardness of the water exiting the softener can vary between 3°fH - 10 °fH / 1.7 °dH - 5.6 °dH / 2.1 °cH - 7 °cH.

9.2 MEDICAL LINE DISHWASHER WITH DOOR/HOOD LOCK DEVICE

The medical line dishwasher with door/hood lock device has a device that prevents door/hood opening for the entire duration of the work cycle.

For the door/hood lock to be active, the parameter tYP

(in the

CFG

family) must be set to

3

.

The dishwasher door/hood is locked at the start of a wash cycle and is released at the end of the final pause after rinse. The wash compartment can be accessed by stopping the work cycle in progress, as the locking device is thus disabled.

A pause at the end of rinse can be set by means of the parameter rPA

(in the dPA

family). This parameter is common to all

3 wash cycles. The rinse water temperature is displayed during this pause. Another final pause in the cycle can be set by setting the parameters

FP1

,

FP2

,

FP3

. During the final pause the display shows the time remaining for completion of the cycle.

The door/hood lock device will be deactivated at the end of the final pause (

FP1

,

FP2

,

FP3

).

For correct performance of the wash cycle the pause at the end of rinse and the final pause must assume the default values

(see Prog 032 – 034 - 035).

9.3 DETERGENT AND RINSE AID LEVEL SENSORS ACTIVATION

By setting the parameter

LES

(in the

CFG

family) to

1

, management of the level sensors located inside the external detergent and rinse aid tanks is enabled. During the rinse phase, when the rinse aid inside the tank has finished, the message rAi 0

appears on the display.

When the detergent inside the tank is finished, the message dEt 0

is displayed and after a number of wash cycles equal to

CdE

(in the dPA

family) the dishwasher inhibits the activation of other wash cycles. Therefore the detergent level in the tank must be restored.

SERVICE MANUAL

9.4 DISHWASHER WITH INCORPORATED CONTINUOUS WATER SOFTENER

Dishwashers with incorporated continuous water softener have a continuous softener in the water circuit. By means of special resins, this device removes the calcareous substances from the feed water, supplying decalcified water for washing.

To activate the continuous water softener set the parameter

SER

(in the

HCP

family) to the value

9

.

For the continuous softener to work properly the resins must be regenerated periodically, with frequency depending on the hardness of the water and the number of wash cycles carried out. Unlike conventional water softeners, this continuous softener does not require machine stops for regenerating the resins.

To regenerate the resins it is necessary to put kitchen salt in the special container located in the dishwasher.

In particular, the salt container must be filled when the dishwasher is used for the first time and whenever the message

SAL 0

is displayed at the start of a wash cycle. The salt container holds up to 1.5 kg of salt.

IMPORTANT: The message

SAL 0

may appear for several wash cycles even after topping-up the salt, as the salt must circulate in the entire system. Correct operation of the dishwasher is not, however, affected.

The number of regeneration cycles performed can be checked by consulting the parameter nrE

in the

Cnt

family of counters.

The hardness of the water exiting the softener can vary between 3°fH - 10 °fH / 1.7 °dH - 5.6 °dH / 2.1 °cH - 7 °cH.
