E08 Mains voltage problems. The voltage is not enough for the operation of the SMA, or it exceeds the allowable rate. Checking the electrical network. E09 Excess foam during spin cycle.

• Wrong selection of powder.
• Overdose of powder.

1. Open the hatch, take out the laundry, remove the foam.
2. Start the rinse cycle.
3. Adjust the detergent dose.

E11 Faulty UBL (door lock). The UBL triac is out of order. Electronic board repair. E21 Engine problems. The drum rotated at different speeds, after which the engine jammed. It is possible that the tachogenerator is defective.

1. The engine and tachometer are being tested. Installation of serviceable elements.
2. Checking the circuit contacts from the control unit.

E22 Uncontrolled rotation of the motor without a signal from the module. The motor triac burned out on the control board. To reset the error, you need to repair the board and replace the triac. E30 Sunroof not blocking The sunroof may not be closed tightly or the sunroof lock mechanism may be broken. Press the hatch door tighter and try to start the wash again. If the error repeats, inspect the blocker and replace in case of breakage.

E31

E32
