Figure 4-9: Circulation Pump – Water Paths
Water is passed to the spray arms via the circulation pump. There are two circulation
pump versions depending on model.
Circulation pump with slide shutter: MPEW (approx. 65 W)
With spray arm alternation, the spray arms are only intermittently supplied with
water. This is achieved via a slide shutter, which is moved back and forth as
appropriate to open or close water paths to the different spray arms. For 30 sec. both
the top and bottom spray arms are supplied and during the next 30 sec. the middle
spray arm only. The total water circulation rate is constant and is approx. 34 l/min.
Detergent is only dispensed when the middle spray arm is being supplied with water.
A hall sensor is located between the pump housing and the motor to measure the
pump speed. Depending on the measured value, the quantity of additional water
required, if any, can be established.
