Transport

Damage to the dishwasher can compromise your safety. Before
using the dishwasher, check it for any visible transport damage.
Never use a damaged dishwasher.

Only transport the dishwasher in an upright position so that no
water flows into the electrical controls, as this would cause faults.

If you wish to transport the dishwasher, empty it and securely
fasten all loose parts such as baskets, hoses, and cables.
Disposal of your old dishwasher

Make the door lock inoperative so that children cannot
accidentally shut themselves in. Remove or destroy the locking
bracket of the door lock, and make appropriate arrangements for the
disposal of the appliance.
