FAULT CODES
In the event of a fault being detected by the electronics, a code will appear in the LCD display.
These are listed in the following table.
• Components with a low resistance to Earth may cause erroneous faults or loss of the display.
• Always check relevant wiring and connector blocks security before replacing the modules.
NOTE: - All automatic programmes; there is no heat during the first 3 minutes. The first 10 minutes
of all automatic cycles is used to calculate the drying time.
ONE-SHOT STAT OPERATION
If the 1 shot thermostat operates and opens, the machine will continue with the cycle with no
heat. A fault code will not be displayed.
