What should I do before operating the washing machine for the first time?

Before first use, you must remove the 4 transit bolts along with rubber bungs by slightly twisting the bung, as they are locked to prevent internal damage during transport. If not removed, they may cause heavy vibration, noise and malfunction. You should also run a cycle with the COTTON 60°C program and half load of detergent without any clothing to remove residues and water from the drum left during manufacturing. (Page 6, 12)
