Page 16: Strainer System
Strainer system The strainer system is one of the systems which are most important to the performance of the dishwasher. The design of this system is largely decisive to whether the dishwasher will be able to perform its most fundamental task: to wash the dishes clean. The strainer system must trap particles of food, etc. -
Page 17: Level Control System
10. Level control system There are two basic ways of metering the right amount of water into a dish-washer. The first is to open the inlet valve for a certain predetermined period of time, while the other is to use some means for measuring the water level in the machine. -
Page 18: Drain System
11. Drain system The system consists of inner and outer drain hoses and a drain pump, and its function is to transport the contaminated water as efficiently as pos-sible from the machine to the waste water system of the buildin The drain pump is connected to the chassis at the coarse strainer and is sealed with an O-ring. -
Page 19: Regeneration
12. Regeneration The water chamber for regeneration contains 350 ml water. During regeneration, the regeneration valve is energized. The 350 ml water runs into the salt container and mixes with the salt to form a brine solution. In the top of the salt container there is an opening with a small filter, from here the brine solution enters the softener where the resins are regenerated. -
Page 20: Thermostats
13. Thermostats The thermostats are pressed into the tubular mountings in the plastic chassis. They measure the temperature on the outside of the plastic wall, which leads to a certain difference between the water temperature thermostat temperature. However, the specifications of the thermostats take this into account. -
Page 21: Temperatur And Safety Systems
In addition, two overheating protections are incorporated into the element, i.e. one at each connection end. These are designed so that they will burn off if the element is switched on but has no cooling water around it. EDW 503 Spares Operation - R.Kurzke 11/06 - 21 - 599 528 133 EN... -
