Are you getting a new washing machine or are you moving? You don't need an installation technician to install the device. A Mila expert can connect and install the machine.
As a rule, you need one of both types of screwdrivers (slotted and Phillips-head), pump pliers and a wrench to remove the transport safety device.
Put the unpacked washing machine in its intended location. Important: remove the transportation safety devices. Hook up the hoses for the water inlet and outlet to the machine. Now connect the water inlet to the water supply and the outlet to the sewage hook up. Level the washing machine. Insert the plug. Do a test wash and observe whether there are any problems like leaking.
