The timer unit software has been inproved to withstand frequency variations from the power
source.
This change has been implemented on units manufactured after week 13, 2000. The part number of the
timer unit does not change.

If the programme unit stops at C = (Check)
Check the following before replacing the programme unit.
Possible error causes:
Thermistor fault
The thermistor output is closed or fully open.
Heating element fault
The set temperature was not reached within:
25 minutes using the Cotton programme or 80 minutes for other programmes.
Water level fault
Overfilling. The mechanical and electronic level guard will indicate a water level fault if the level has not
been reached within 5 minutes or if the level has not been reached within 3 minutes when draining.
Level guard fault
The machine does not heat; it takes too long time (approx. 3 hours).
If the machine does not exhibit any of the above faults, but instead carries out all the programme steps
and then stops at C, then the programme unit should be replaced.
