The steam generator’s magnetic drain valve will automatically open 15 minutes after the bathing programme has finished. After the tank has flushed (2 minutes) the drain valve will close and the water solenoid valve will open and fresh cold water will fill the tank up to the upmost level probe. Once the tank is full, the drain valve will open again and the tank will drain and remain empty ready for the next use. During the flush and rinse cycle, the outermost segments of the screen will "go around” in circles. During the flush and rinse cycle, you cannot start a new bathing programme nor can the cycle be interrupted.
