Error Code 9C1
Your dryer is getting the wrong voltage from the outlet
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: 9C1 / 9C2
What This Means
Under or over voltage supplied to the dryer; Plug receptacle is used (voltage drop through extension); Main PBA fault (sometimes); Momentary low voltage on connecting wire over 1m can drop up to 10V
What actually causes this:
The electrical outlet isn't providing the right power — could be a tripped breaker, loose plug, or wiring issue.
First Thing to Check
Check your electrical panel and make sure the dryer's breaker hasn't tripped — flip it fully off then back on.

- 3
3. Check the voltages (error occurs when under or over voltage is supplied)
- 4
4. Check whether a plug receptacle is used - when connecting wire is 1m, a momentary low voltage may drop up to 10V
- 5
5. If voltage is correct, suspect Main PBA fault
