Fault code 04, NTC LOW TEMP
This fault code is generated by the programming CPU card. This fault code
is displayed if the temperature around the NTC sensor is below approx. -9
degrees C.
A low temperature means the resistance in the sensor is too high, above
approx. 23.7 kohm. This can be because the machine has been standing
outdoors, an open circuit in the sensor, a break in the cable to the sensor,
etc.
The resistance should be as shown in the table below:

20 5850
21 5600
22 5350
23 5100
Fault code 05, NTC HIGH TEMP
This fault code is generated by the programming CPU card. This fault code
is displayed if the temperature around the NTC sensor exceeds +98 de-
grees C.
A high temperature means the resistance in the sensor is too low, lower
than approx. 350 ohm. This can be caused by a short circuit in the sensor,
break in the cable to the sensor, etc.
Fault code 06, WATER IN MACHINE
This fault code is generated by the programming CPU board. This fault
code may appear only in the case of rapid advance to the end of the
program. The fault code will appear if the level system has not indicated
“empty drum” within a certain time (approx. 3 min). This time may vary
depending on the size of the machine.
