Having your washing machine leaking water on the floor is one of the worst nightmares. Now Bosch comes with a solution to solve that and it brings the new AquaStop Leak Protection System. If you do have a leak in the machine, this system will stop the water. The system works by shutting down the unit and pumping out all the water in the machine if the overflow switch detects water in the base. There is one double-walled inlet hose that can easily recognize a leak in the hose and immediately stop the water supply at the source. You are able to find AquaStop in the new Visio machine from Bosch. The Vision line features EcoSmart technology, ActiveWater and EcoAction. Prices run about $1,000 to $1,500 per appliance.
