17 Error messages and repair methods

Ghibli AW display indicates error messages as hex codes. They are saved in the error code
memory (select error code memory see chapter 6.10).
Several error codes are not displayed as hex codes, but with special views (see column
"Reason").
Note regarding error detectability: In standby not all errors are detectable. Several errors will
be detected not before approx. 30 seconds after switching the tool on (electronic control,
heating up).
Error no. Reason

Description / Repair method(s)
Indicates a blank error code memory entry
Thermocouple defective or incorrectly connected
1.) Check thermocouple connection (chapter 9.4)
2.) Replace thermocouple (chapter 9.4)
3.) Replace electronic circuit board HCU (chapter 10.3)
Heating element defective or not assembled
1.) Check heating element connection (chapter 9.3)
2.) Replace heating element (chapter 9.3)
3.) Replace electronic circuit board HCU (chapter 10.3)
Triac defective, line/mains voltage below defined range
1.) Check line/mains voltage
2.) Replace electronic circuit board HCU (chapter 10.3)
Print adapter front defective
1.) Replace electronic circuit board HCU (chapter 10.3)
Line/mains frequency out of range or not detectable (print
adapter front defective)
1.) Check line frequency, respectively make sure tool is con-
nected to line/mains frequency of 50/60Hz ± 10%; there is no
hardware defect if this error does not occur any more when op-
erating tool with correct line/mains frequency
2. If error occurs when operating tool with correct line/mains
frequency, replace print adapter front (chapter 10.3)
Temperature print adapter front > 105°C (>221°F)
Temperature in blower housing top may exceed ambient tem-
perature up to 25°C (45°F) because of motor waste heat
1.) Check motor/blower unit (motor runs, air flow exists?)
2.) Ambient temperature too high
3.) Clean air filters (clogged?)
4.) Check heating element (clogged?)
5.) Replace electronic circuit board HCU (chapter 10.3)
