  • Page 8: Design And Function

    Design and function Safety system Water can leak from various points on the appliance: • Leakage water hose of the Aquastop • Outer tub 3.1.1 Structure • Seal The leaking water collects in the base support. The increasing water level in the base support lifts the float and actuates the safety switch.
  • Page 9: Safety Switch

    Design and function Safety switch The Aquastop valve is deactivated. The wash liquor is pumped off. 3.2.1 Structure Fig. 2: Components of the safety switch Float Safety switch The float (1) is in the base support. The safety switch (2) is situated above the float. The float and switching contact of the safety switch are mechanically connected to each other.
