flows through the top spray arm, approximately 9 gallons per minute through
the middle spray arm and approximately 5 gallons per minute through the
bottom spray arm. This pump version does not have a speed sensor.
This pump is equipped with a winding changeover, which increases the
torque at the moment it is switched on (higher starting torque). In this state
the main winding is connected directly, and the auxiliary winding connected
indirectly via the capacitor, to the power supply. During normal operation the
efficiency is increased. The main winding is switched parallel to the capacitor.
The winding changes are made via a changeover relay on the electronic
module. At every switch-on, the changeover relay and the circulation pump
starting relay are supplied with power at the same time. The changeover
relay switches the windings with a time delay.
This circulation pump has thermal winding protection.

Converter)
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 seconds both the top and bottom spray arms are supplied and during the
next 30 seconds the middle spray arm only. The total water circulation rate is
constant and is approximately 35 L/min.
Detergent is only dispensed when the middle spray arm is being supplied
with water.
The circulation pump is primed via the middle spray arm water circuit.
Therefore, at the start of a program, the water path control appliance first
directs water to the middle spray arm.
The MPEW version installed in these models has an integrated speed (Hall)
sensor.
