The Owner's manual was very helpful. The WEGA is about 35 years old and needed repair.
Your Website is pretty good und easily to handle.

Connect the water inlet hose to a tap with a 3/4" thread. The other end of the inlet hose which connects to the machine can be turned in any direction. Simply loosen the fitting, rotate the hose and retighten the fitting, making sure there are no water leaks. The inlet hose must not be lengthened. If it is too short and you do not wish to move the tap, you will have to purchase a new, longer hose specially designed for this type of use.
The end of the drain hose can be positioned in three ways: Hooked over the edge of a sink using the plastic hose guide supplied with the machine. In this case, make sure the end cannot come unhooked when the machine is emptying. This could be done by tying it to the tap with a piece of string or attaching it to the wall. In a sink drain pipe branch. This branch must be above the trap so that the bend is at least 60 cm above the ground. Directly into a drain pipe at a height of not less than 60 cm and not more than 90 cm. The end of the drain hose must always be ventilated, i.e. the inside diameter of the drain pipe must be larger than the outside diameter of the drain hose. The drain hose must not be kinked. Run it along the floor; only the part near the drainage point must be raised.
