Service Manual - Dishwasher Models DDW24S, RDW24I and RDW24S
Cycle Process Description
Presented below is a detailed description of the Quick cycle process. This description applies to a DDW24S with no options selected. If
the component test in the service menu is not sufficient to identify a fault, you can run the Quick cycle and compare the results with the
process description below. If they are in agreement this indicates a correctly functioning control unit.

Explanation
Cleaning
process
*
Cleaning cycle for container 90 sec The circ. pump stops and the drain pump runs for 2 sec. The circ. pump runs for 3
sec. and then rests for 5 sec. This repeats a total of eight times, but the fifth time the
circ. pump may rest for 8 sec instead of 5 sec.
Inlet
process
**
Inlet process 255 sec The flow meter signals the flow in pulses. The control unit determines the number of
pulses for each inlet. If not 80 pulses has been reached within 60 sec or a specific
number of pulses is not reached within 255 sec, the program will interrupt.
Drain
process
***
Drain process 120 sec The drain pump starts and pumps out until the level sensor reaches a specified value.
After that, the drain pump continues for additional 10 sec. The total time depends on
how long it takes to reach the specified value from the level sensor. If the specified
value is not reached within 120 sec, the program will interrupt.
