The water protection system

The Miele water protection system pro‐ tects all parts of the washing machine from water damage.

The system consists of three main components:

–the inlet hose

–the electronic unit and drainage and overflow protection

–the drain hose

Inlet hose

–The casing on the inlet hose contains two solenoid valves , which cut off the water intake directly at the stop‐ cock. These valves provide two-fold protection. In the event that one of the valves is faulty, the other valve will cut off the water intake.

Blocking the water intake at the stop‐ cock means that the inlet hose is on‐ ly under pressure whilst water is be‐ ing taken into the machine. For the remainder of the time, pressure on the inlet hose is negligible.

–Protection against the solenoid valves bursting

The solenoid valves are pressure tes‐ ted to between 7,000 kPa and 10,000 kPa against bursting.

–The double-skinned inlet hose  has a pressure-resistant inner hose and a protective sleeve. Any leaking water is fed into the sump  through this protective sleeve. A float switch  closes the solenoid valves, prevent‐ ing any more water flowing into the machine and water in the suds con‐ tainer is pumped away.
