The electronic Easytronic plus control is a further development of the Easytronic and has additional functions. This Service Manual deals only with the Easytronic plus and the additional components.

Disassemble the Base Panel

Shift the base panel to the left and remove it.

Electronic Speed Identification for the Upper Sprayarm

The speed identification consists of a magnetic sensor (Hall generator) which is actioned by a magnet in the upper sprayarm.

The recording of less than 4 revolutions causes the fault display "sprayarm blocked".

Circulation Pump with Rotary Slide

The circulation pump is driven by a single-phase asynchronous motor with an auxiliary winding. The auxiliary winding is connected by a 4mF capacitor. The rotational speed is controlled by a tachymetric generator. There are three speeds for washing: 1600 rpm, 2000 rpm, 2800 rpm, capacity 30 W.

Dishwasher Specifications

Fully-Integrated, Integrated, Substructure, Upright Dishwashers with Flow-Type Heaters and Easytronic Plus

At the pressure connecting piece of the circulation pump there is a rotary slide which guarantees the water supply to the upper sprayarm alternating with the lower sprayarm and the ceiling shower and/or the ceiling sprayarm. During the heating phase only the upper sprayarm is operating.

Ceiling Sprayarm

The new cutlery basket is placed at the upper dishwasher basket. The ceiling sprayarm sprays the water directly onto the cutlery basket and guarantees an excellent washing result with the cutlery placed in that basket.

Turbidity Sensor

The turbidity sensor function is only activated in cycles "AUTO 65° and AUTO BIO 50°".

Function:

The input voltage with the turbidity sensor may be between 6 V and 11.4 V. (The measurements are described in detail in the chapter “Measuring Points at the Electronic Control (in the base)"). For clear water the output voltage must always be 4.3 V. If that value differs due to soiling of the turbidity sensor after a longer operational period, the Easytronic plus recontrols the input voltage with the turbidity sensor automatically until the output voltage is 4.3 V. This happens during the final rinse cycle. If the 4.3 V is not achieved within 8 seconds, the fault “C5” is stored in the fault memory. If the output voltage falls below 3 V in the prewash cycle and below 3.8 V in the intermediate rinsing cycle, turbid water will be detected. With the service test routine the turbidity sensor will be calibrated to 3.5 V not with water but with air. That corresponds to 4.3 V with water.

“Superwash” or “Soaking” Function (Option)

Can be selected for which cycles?

• Using the separate option key, which is placed on the right side of the appliance (output side), it is possible to select in addition the "soaking" and "superwash" function respectively for following cycles:
  • intensive 70°
  • intensive 65°
  • normal 65°

For all other cycles this function is not possible.

How does this option affect the cycle run?

Description of Cycle Differences

• Essential changes in the prewashing
  • Hot prewash with temperature increase: Temperature will be increased from 40°C to 55°C.
  • A two-times soaking phase of 5 minutes each will be inserted. Between these phases the circulation pump will shortly be actioned. During that time the soiling will be dissolved or soaked.
  • Additional prewash times of a total of 7 minutes will be inserted. In doing so the temperature of 55°C will be kept by a possible re-heating.
  • With selected option, the "prewash" cycle will be extended by approx. 18-20 minutes.
• Essential changes in the washing
  • Additional 6 minutes of washing with heating to a maximum of 55°C.
  • Additional 20 minutes of washing at a controlled temperature of 70°C (resp. 65°).
  • With selected option, the "prewash" cycle will be extended by approx. 26 minutes.
• The option does not intervene the cycle run of final rinse and drying. With "normal 65°C" however, the 2nd intermediate rinsing already included in the intensive cycle will be inserted additionally.

How to add detergent?

• It is possible to add detergent twice.
  • Quantity: 30 g each or 1 tablet for the start.
  • Fill the detergent in the door for the hot "superwash" prewash.
  • Fill it in the detergent dispenser for the "superwash" cycle.

Cycle Functions

Start-Time Preselection (SZV)

• The start-time preselection can only be activated before the cycle starts with the switched-on appliance.
• An activated start-time is confirmed by a red LED “SZV”.
• It can be selected scrolling by each pushing the key: The time is indicated by a 2-digit 7-segment display (1 - 2 - ... - 19 - 0 - 1 - ...).
• 6 seconds after last pushing the key the timer of the preselection time will be started, if an effective washing cycle has been selected.
• The preselection time can be changed at any time during the whole start-time countdown.
• 6 seconds after the time preselection has count down the selected washing cycle will start.
• If no washing cycle was selected, the adjusted SZV (start-time preselection) value will stay and flash until an effective cycle has been selected. After a cycle has been selected additionally, the cycle LED, the PAA and the 7-segment display will still flash for 6 seconds (possible time for a change) and will light permanently afterwards. The start-time preselection is now activated. The PAA will go out until the cycle starts.
• The start-time can be cancelled alone or along with the cycle.

Display of Remaining Time

• The remaining time indicates the expected running time of the selected cycle combination.
• The display is indicated in minutes.
• The display of the remaining cycle running time is indicated by a 7-segment display.
• The display is 2 1/2-digit. This means a maximum of “199” minutes can be displayed. With times more than 199 minutes the time 199 is indicated until the cycle running time is below that figure. Only from that time the remaining time will be updated again automatically.
• After switching on the appliance without having selected a washing cycle the 7-segment display and the running time LED will remain dark.
• If a washing cycle has been selected, the LED "running time" gives a red light, the 7-segment display flashes and will light permanently from the cycle start.
• The indicated times are to be taken from a table which is adjusted to the particular process steps. A correction factor depending on the load is considered when calculating the running time.
• If the door is opened during the washing or final rinse phase, this may for technical reasons result in "jumps” of the running time display when closing the door again.
• Digit “1” (= 1 min) shortly before the end of the cycle will be indicated as long as the appliance is still “working”. Digit “0” will be indicated only at the actual end of the cycle, as soon as the control got into the final state.

Information: The 7-segment display among others also indicates the fault display. (see chapter "Table of Fault Displays")

Display of Cycle Run

There are depending on variants:

• The cycle run is displayed by 6 LEDs arranged vertically.
• Following cycle steps will be indicated: "prewash" - "wash" - "rinsing" - "final rinse" - "drying" - "end".
• The indicated cycle steps are adjusted to the process run.
• Selecting a cycle key, but before the actual cycle start, all cycle steps included in the cycle run will be indicated simultaneously.
• After the cycle start only the LED relating to the corresponding working process will still light.
• The switching from one cycle step to the next one is made step-by-step.
• "End” is only indicated at the actual end of the cycle, when the control got into the final state.

Status Display

• LED display salt
  • "on" when salt must be refilled
  • goes out after salt addition
• LED display rinse-aid
  • "on" when rinse-aid must be refilled
  • goes out after rinse-aid addition
• LED display water
  • "on" with missing or insufficient water fill
  • see chapter Operation 10 - "C1"-fault
• LED display sieve
  • "on" (if counter has reached 20) at the end of the cycle
  • goes out after the start of a new cycle - counter is reset to 0
• LED display door
  • "on" with door opened during the cycle run
  • goes out when door is closed
• LED display sprayarm
  • "on" with blocked middle sprayarm
  • additional acoustic signal

Energy Label AAA

In order to be able to lead the optimum value “AAA”, among others following features have to exist and/or conditions to be made.

Drying by Fan

• To get a very good drying result a fan drying is absolutely necessary.

Positioning of Sprayarm

• At the end of the final rinse the middle sprayarm is in a defined position.
• This is to avoid that water will drop to the dry dishes and worsen the drying result when drawing out the upper basket.

Intelligent Monitoring of Heating

• A connection will be made between the required heating time during washing and final rinse and the running times in the individual cycle phases.
• If the adjusted maximum heating time should not be sufficient to heat up to the required temperature, the heating will be interrupted in this step. This may happen e.g. by a very cold water fill or dishes.
• The still missing temperature will be compensated by an additional cycle running time which is determined in a table. Thus the cycle phase period of "washing”, “final rinse" or "drying" could be extended.
• This is to guarantee that the energy value required for AAA will not be exceeded, but at the same time will not worsen the washing result.

Miscellaneous

• Sprayarms with an optimized arrangement of nozzles, in addition a third sprayarm instead of a ceiling shower.
• Cutlery deposit and optimized dishwasher baskets.
• Optimized process technology.

Cycle Phases Being Actively Affected by the Fuzzy Detection of Load:

(Changes when detecting half and/or empty load)

• Reduced duration of washing (depending on the particular cycle, between 4 and 6 minutes).
• Drop of 2nd rinsing with all intensive cycles.
• Reduced duration of rinsing (approx. by 2 minutes).
• Temperature reduction by 5°C in the final rinse in appliances with an active drying (exception: 50° cycles).
