Continental Girbau Washer Error Code ALn / V-10: Inverter Input Voltage Wrong
ALn / V-10 means the voltage reaching the inverter is outside its allowed range. Turn the washer off for a minute and restart it once. If V-10 returns, a technician should measure the supply at the inverter before any part is replaced.
High: the inverter refuses to drive the motor and the washer stays down.

What does Continental Girbau error code ALn / V-10 mean?
Before an inverter will drive the drum motor, it checks the voltage arriving at its input terminals. The check is simple: the reading must sit inside the range the drive was built for. If the supply is too high or too low, the inverter refuses to run and the E-Series control displays ALn / V-10. The ST-101 sheet gives a short list of actions. The inverter parameters are downloaded again and verified, which needs the door to be closed. Next come the motor discharge resistor and earth, power at the inverter, the fuses and relay, and the communication harness. If all of those are fine, the inverter itself may be bad. The only cause the manual names is incorrect incoming voltage to the inverter, so the supply is where the work starts. Because the control also compares stored inverter parameters with what the inverter reports, wrong or damaged parameters can show up as a voltage alarm, which is why the manual asks for them to be verified.

What you may notice
- ALn / V-10 on the display
- Cycle will not start the spin or stops after the fill
- Alarm worse at busy times when the building voltage sags
Possible causes
Listed in Continental Girbau's documentation
- Incorrect incoming voltage to the inverter
Other likely causes — what usually sits behind error code ALn / V-10 on this control. A technician confirms which one it is before any part is replaced.
- Washer wired to a feed that sags when large equipment starts elsewhere in the laundry
- A supply lug or breaker terminal running hot and dropping voltage
- Inverter parameters lost or changed after a board replacement
Safe checks before calling for service
- Press stop, then give the drum time to coast to a halt.
- Switch the washer off at its disconnect for one minute and restart.
- Check whether other machines on the same circuit show trouble at the same time.
- Leave the control box closed. Note the time of day and whether the building had a power flicker.
How a technician diagnoses error code ALn / V-10
- Read the alarm and confirm the machine type.
- Measure the voltage at the inverter input at idle and while the cycle starts.
- Download and verify the inverter parameters with the door closed.
- Check the discharge resistor and earth, the fuses and relay, and the communication harness.
- Replace the inverter only if the supply and parameters check out.
- Reading the incoming voltage means working on energized 208-240 V or higher terminals.
- The parameter download needs the maker's service tool and the right data for this model.
- A supply problem may begin in the building panel, which a licensed electrician has to correct.
How error code ALn / V-10 differs from similar codes
V-10 is an input-voltage alarm, while V-15 reports low voltage seen by the inverter and VAR 5 reports high voltage on the DC bus.

Is V-10 a problem with the washer or the building?
Either one. The manual lists incorrect incoming voltage first, so the building feed is checked as well as the washer.
Can I keep running other washers on the same circuit?
If they run normally their supply is probably fine, which helps point to this machine's own wiring.
Will it clear by itself?
A one-time voltage dip may clear with a restart. If the supply is weak it will recur.
