Green Kitchen Concept

Water from Wash phase (Final Rinse, Intermediate Rinse, Main Wash or Purge –

depending of application) will be stored in re-use tank for a period of time and later

re-used in the first wash phase (Pre Wash or Main Wash).

Water Re-Use is possible for 3 different Cycles/ Programs:

Reference Cycle:

6 Liter declared = saving of 40% of water vs. current cycle

Intensive Cycle:


Overnight Cycle:


Additional:

Automatic clean out cycle every 30 runs

Automatic drain from the tank after 72h



LEIA – water re-use system

Cycle implemented to clean Water Re-Use Tank is activated automatically every 30 days or

every 30 washing cycles (depends what happens first).

After Purge or Intermediate Rinse wash phase of the cycle, 4,0 liters of fresh water is filled into

the dishwasher and heated up to 68°C.

Once required temperature is reached, water is transferred into the Re-Use Tank, stays for ca.

30sec, flows back to the dishwasher, and is transferred again into the Re-Use Tank.

The operation is repeated 3 times and finally, water is drained out completely from the

dishwasher. The complete operation takes about 40 minutes.

AUTOMATIC DRAIN OUT

After 72 hours (3 days) without a new cycle being run, the machine will automatically drain

the tank.

Draining water from DW after 72 hours and Clean Out sequences are running automatically in

the first cycle (except short Initial Wash cycle) after power off occurrence.

Service set Yoshi user interface and buttons

1) Description of service set usage and related parts:

In order to avoid any possible electrostatic discharge impact and mechanical damages,

especially micro breaks of user interface PCB during service intervention, as well as to

reduce time of intervention, user interface Yoshi and lightguides/buttons component for

free standing and build in appliances are now offered by Service as already assembled

configuration, available in service sets.

Previously available separate components:


Service set Yoshi UI + lightguides buttons (position in spare parts list: 3500)


Assembly instruction of Service set Yoshi user interface and buttons

Service set includes full version of lightguides/buttons component. Please remove

unnecessary buttons and lightguides according to specification of the component (compare

with original part). We recommend using diagonal pliers as it is shown on the example below:

1. Using diagonal pliers to cut off buttons.

2. Cut off light guides.

3. Component ready to assembly.


Running Time Display

The improvement is available only to V-Touch CB 480140100554 (461972587621)

starting from Software Version 27 onwards.

The most convenient way is to verify Software

Version directly on Control Board

Cycle time indication before cycle is started

In case of old Software (> ver. 27) it was an

average values of last cycles stored in memory.

This was leading to various values being

displayed and noticed by customer during

Sensor program selection. Now (starting from

version 27) it will be displayed constantly the

same time as stored by default, with only

changes due to selections of options or features

(i.e.: Power Clean, Half load, etc.)


Indication of 6th sense decisive points

Previous (>ver. 27) decisions made by Sensor were not indicated, this was leading to

unexpected time changes displayed for customer during the running cycle. Now (starting from

version 27) it will be indicated by a "spinning snake animation" displayed for 30 sec. and

shown before the remaining time change (if the change requires a remaining time difference

higher than ±1 minute).

There is also a change linked with Dispenser activation during Test Cycle. Previously (>ver.

27) during repeating Test cycles, the Dispenser was not activated – now (starting from

version 27) it will be activated every time the Test cycle is executed (even if it is repeated).

Summary:

When the old CB is replaced by the new one (with CB Software equal or higher version 27)

customer should be clearly informed about improved functionality in terms of cycle

duration indication and indication of decisive points of Sixth Sense Technology and

Sensor’s decision.

Running Time Display


VIRTUAL RINSE AID INDICATOR VRA (only Atlantic appliances)

Rinse aid presence during the cycle is detected by Optical Water Indicator.

Therefore, in appliances with VRA, you will find no reed contact for rinse aid in the

detergent dispenser and no wiring between reed contact and control board.

During final rinse, dispenser opens twice to release the rinse aid.

Optical water indicator measures the turbidity of water just before the release of rinse aid

and 90 seconds after the release.

Adding rinse aid to warm water causes slight foam which is detected by OWI as change

of turbidity. In case of missing rinse aid the turbidity does not change during measurement

and this signal is recognized by the control board as “Rinse Aid Empty”

If it was detected, that no rinse aid was released in 2 consecutive cycles, the LED

indicating “Rinse Aid Empty” will turn on at the end of the cycle.

In case, that the customer add rinse aid, the “Rinse Aid Empty” indicator LED will be

turned off after closing the door.



In case that the customer will not add rinse aid, the “Rinse Aid Empty” indicator LED will

stay turned on when the door will be opened and closed or the CANCEL button will be

pressed.

After the next cycle without rinse aid, the LED will turn on again at the end of the cycle.

Procedure will repeat until the customer refills rinse aid.

If the current detergent setting is powder detergent, the “Rinse Aid Empty” indicator LED

will be activated to show that rinse aid is needed.

If the current detergent setting is tablet ”Rinse Aid Empty” indicator LED will be not

activated.

If the OWI becomes disabled (unable to calibrate), because of filming due to hard water or

food soils, the rinse aid detection is no longer activated. The “Rinse Aid Empty” LED

indicator will never turn on.



Attention:

The Detergent dispenser you will receive ordering code 480140101374 is equipped with

reed contact for rinse aid (purpose is to cover also the previous POINT DW platform).

In that case, there is no need to connect the reed contact for rinse aid to the control

board.

Description concerns appliances with Virtual Water Indicator (VWI) and SMART motor

(valid also for appliances with MPH motor and VWI).

The information about water presence in the system (foam, stability of motor operation) is taken

by measuring the loads on the pump.

On the base of that information from the pump, the InCoRed control board takes a decision.

Procedure:

During the draining phase, both pumps - drain pump and spray pump (as water indicator) - are

working. If, after 2 min of draining, the load on spray pump do not change (means water is still in

the system on a certain level) F4 is displayed.

We have to exclude below mentioned reasons for improper spray pump operation, and check

CB (following failure tree).

Factors, which have an impact on spray pump operation are:

1) Mechanical:

- Damaged rotor, blocked rotor, damaged clutch, damaged electrical connection between CB

and motor.

2) ) Hydraulic:

- Blocked spray arms, blocked flow through on pump or hydraulic system (e.g. dummy cap at

the customer syphon connection), not enough water for proper work of motor (leakages, wrong

outlet hose installation, blocked filters, foam).

SMART Motor with Virtual Water Indication


„I have a feedback from the field on this model ADP5777 – 851151529933.

(InCored control board, appliance with SMART motor)

We have 4 cases with the same issue in 2 different customers (Boulanger and Leclerc)

I already got 2 serial numbers 381029007474 and 381028011511.

The products have worked one month.”

Issue : A program is launched, then after about 5 minutes the DW stops and shows

"End„ .No defect failure indicated. No dry”

Result of Service Intervention:

“CB has been changed and reprogrammed - without success.”

There are a few issues, which result in “END” without error indication:

1) clogged, blocked motor (e.g. due to broken glass) => motor is not able to start. Without

proper VWI signal from the motor, the DW is not able to check the water presence and take

the decision to switch on the heater. Therefore the cycle is interrupted and ended (it should be

indicated as F5 failure during Service Test Cycle).

2) Significant instability (foam, clogged filters, or in case of SMART motor - disconnected feed

tube and/or an incorrect "working point" (in terms of hydraulic performance - pressure vs.

flow) results in filling additional water, phases repetitions and if this does not help, the cycle is

interrupted and ended.
