4.19 Drain Pump, Circulation Pump
The Drain Pump (M8) is located below the cabinet and connects to the
right / front of the Sump. The Pump removes the wash water through
the Non-Return Valve and Drain Hose to the on-site drain. The Drain
Pump is controlled / powered by the electronic.
Note
If the on-site drain is below the level of the guides for the bottom
basket, the drain must be vented to prevent siphoning. See the
appropriate operating/ installation instructions or call Technical Support
for assistance.
During dishwashing, the Circulation Pump (M6) takes in the wash
water from the side of the Sump through the Microfine Filter and the
Large Surface Area Filter and pumps it to the Spray Arms. During
drainage, the Drain Pump removes water out from below the Microfine
Filter. This change of direction in the water flow assist in flushing out
any residues that may have been retained within the Filter. Water
passing through the Non-Return Valve and then to the on-site drain.
A Bimetallic Switch is integrated in the Circulation Pump Motor
Windings and serves as a safety cut-off should the temperature
exceed 150°C (302°F). After a cooling-down phase, which can be
between 10 min - 1 hour the Switch resets automatically. If the Switch
is faulty, the Motor Assembly must be exchanged.
