AL01 indicates activation of the anti flood device.
It sounds like water has leaked into the base of your machine.
Pull the appliance out, unplug it from the wall socket and tip it rearwards about 45 degrees. Drain the water out and once empty the anti flood should reset.
Try the machine again. If it faults during the test you may have a leak into the base.
The main circulation pump is located in the sump.The drainage pump can be located by following the drainage pipe into the appliance.,This pipe is attached to the pump.
