Wash block water intake start:
a Measuring time for 0.26 gallons (one liter)
1 Normal water intake time sufficient (1 minute in this example)
2 Extended water intake time required (2 minutes in this example).
3 After 0.26 gallons (one liter) intake, it is clear that neither the normal nor
the extended water intake time will be sufficient. Therefore, the test routine is started.
Test routine:
a Measuring time for 0.26 gallons (one liter)
b Test routine successful; water intake time is extended.
c Test routine unsuccessful; fault code F19 is registered.
a. During the first step, water intake solenoid Y2 is activated in order to let another 0.52 gallons (2 liters) flow into the machine. The required time is calculated on the basis of the time that the 0.26 gallons of water already in the machine required for intake.
Note: The volume of water cannot cause the machine to overflow, even if the flow meter is inaccurate. Circulation pump M6 is now activated for 2 minutes in order to wet the dishes in the dishwasher and to fill any spaces with water. Drain pump M8 is then activated for one minute. This creates a measurement basis for the actual test. During the test, water inlet valve Y2 is activated until a defined number of pulses corresponding to a water volume of approximately 0.37 gallons (1.4 liters) is reached. Circulation pump M6 is then activated once more.
b. The program continues to run without interruption. The maximum water intake time is extended to 4 minutes. This time value is saved by the electronic for future water intake. For future water intakes, if the time needed for 0.26 gallons to flow into the machine differs by 15 percent, a new test routine flow will be started.
c. If heater pressure switch B1/13 is activated, the program is interrupted immediately, the drain pump is operated, and fault F19 is registered.

A check should also be made to ensure that the type of detergent used matches the setting. When, for example, combination products (2-in-1 or 3-in-1 tablets) are used but the corresponding parameter has been set to Normal, rinse aid will be dispensed twice.
Cause:
Heater pressure switch defective.
Remedy:
Replace the heater pressure switch.
Cause:
Pump pressure too low.
Remedy:
Clean the circulation pump and remove any foreign objects that may be present.
Cause:
An item has tipped over and a large quantity of water is retained, e.g., in a bowl, and is then not available for the wash water circuit. This reduces the pump pressure.
Remedy:
Follow the loading information given in the operating instructions.

Float switch fault
After the WaterProof System has activated, the program is interrupted and the drain pump is operated. The fault will be indicated in the display or via LEDs. The buzzer is activated for as long as the fault is detected.
Note: The drain pump continues to operate even after the appliance has been shut off. The drain pump can only be deactivated by disconnecting the power supply connection.
Cause:
Water in the drip pan. Changeover contact of overflow float switch B8/3 closed from 1 to 4 (refer to the wiring diagram).
Remedy:
1. Remove the water from the drip pan (e.g., with an absorbent cloth).
Note:
Upon opening the appliance and removing all water, there should be no smudges, smears or traces of deposits. Take pictures of any deposits, if possible, and note their type (rust, calcium, detergent, or salt?).
2. Check all hoses, connections and threaded unions for leaks.
Note:
If the leak source has not yet been detected, check the following areas in the toekick and the drip pan for wear and tear: Connection between the circulation pump and the sump Axial face seal of the circulation pump Connection between the drain pump and the sump Connection between the salt container and the water intake Connection between the water intake and the cabinet side wall Overflow (e.g., excess foam formation) Water level between the overflows ( seating of the lower door seal?) Connection between the cabinet and the salt container Non-return valve in the sump ( water running back from the drain hose?)
3. Check overflow float switch B8/3 for continuity and correct operation.
4. Carefully dry all electrical components in the drip pan area.
Cause:
Float switch defective.
Remedy:
Replace overflow float switch B8/3.
Cause:
Drip pan warped after transport.
Remedy:
1. Remove the drip pan.
2. Bend the drip pan straight or replace it if necessary.
