Quietness is an essential design element in a household dishwasher and bosch have made sure that their machines are among the quietest in the world. The last thing you need to hear as you try to sleep or worse still over the television is a dishwasher working away sounding like an aircraft engine. Many review sites and consumer surveys will show that these machines are top in the ratings for low noise levels. One of the major reasons for this is the way that two electric motors are incorporated into the machines design rather than one which is what you find in most dishwashers. Using two smaller suspended motors is quieter than using one larger one and also reduces vibration which is another source of noise. The second reason for them being so quiet is cotton insulation along with a bitumen coating on the sides of the machine.
Heating the water is one of the most expensive parts of running a dishwasher sequence. Traditionally an element at the bottom of the appliance that is submerged when the machine is filled is used to heat the water all at the same time and this use's up a lot of energy and it takes time to get the water to the required temperature. The system designed by bosch use's a chamber with small heating coils located at the water inlet to quickly heat the water to the correct temperature as it enters the machine thereby saving both time and money.
Sensors are used throughout the dishwasher cycle to keep the amount of soap, water and energy used to as low a level as possible. One sensor detects load size or how many dishes are in the unit and can distinguish between plates and pots. As the cycle runs another sensor can actually detect how much more cleaning is required by measuring how the clear the water is and another sensor checks constantly the water temperature. The sensors readings are used by the machines processor to control and adjust the washing cycle length, temperature, detergent usage and rinse time. This allows the best possible wash at the minimum cost saving you time and money and being more energy efficient.
Bosch also has a unique way of drying the dishes at the end of the wash and rinse cycle that does not involve a separate drying cycle. The drying cycle is actually built into the rinse cycle by making the final rinse water very hot. It then condenses on the walls of the dishwasher leaving the dishes dry and the reason this happens is because the washer walls are made of stainless steel which is a cool material. It is a combination of cool stainless steel and very hot water that causes the condensation effect that effectively dries the dishes.
Leaks in an appliance can cause a lot of damage and repairing this damage can be very expensive. Bosch dishwashers have an Aquastop leak system built into them which consists of a water sensor located in a small well at the lowest part of the machine. If water is detected within the machine then something is leaking and the machine automatically shuts of the inlet and drains the machine before any serious damage can be done.
