Test Functions D21-28
D21 Water level
Here it is possible to read the status of SE2.
In the display next to ”Time”, the conductivity is shown and it is indicated whether the water
level is high or low
XX|LO= low water level, XX|HI= high water level.
XX = conductivity of the water.
Default setting is approx. 80 with no water and 40.60 with water. The better the conductivity,
the lower the measured value.
D22 Thermo-switch oven
Here it is possible to read the status of Q1 and Q1A.
In the display next to ”Time”, it is shown whether the circuit is connected or disconnected.
OF= disconnected ON= connected.
In the event of defects, it is possible to reset thermo-switches Q1 and Q2 that are located at
the bottom of the oven below the operation panel.
Note: Q2 is only found in ovens with 2 fan motors (1.16 and 1.20). Q1 and Q1A are
series connected which is why there is only one input signal.
D23 Thermo-switch fan
Here it is possible to read the status of S2 and S2A
In the display next to ”Time”, it is shown whether the circuit is connected or disconnected.
OF= disconnected ON= connected.
In the event of defects, wait for 10 – 20 minutes, then try again.
Note: Q2 is only found in ovens with 2 fan motors (1.16 and 1.20). S1 and S1A each
have their own input on the IO board hence 2 x status (On On / OF OF / On OF / OF
On).
D24 Damper switch
Here it is possible to read the status of M3.
In the display next to ”Time”, it is possible to read the status of the damper motor switch.
OF= damper open, ON= damper closed.
D27 Pump for detergent
Only possible on ovens with CombiWash
This function activates pump M5.
You activate or deactivate the function by pressing the step key.
To pulse, press the alarm key.
0= OFF, 1= ON.
D28 Pump for rinse aid
Only possible on ovens with CombiWash
This function activates pump M6.
You activate or deactivate the function by pressing the step key.
To pulse, press the alarm key.
0= OFF, 1= ON.
