disintegrates the food particles that come off your dishes so
they don't end up recirculating and sticking to your dishes and
glassware.

powerful motor on the market, so you

clean.

How Chopper Works (See Figure 1)
1. Water and food particles flow through the coarse filter
then are disintegrated by the Chopper blades (A).
2. An impeller pulls soiled water into the wash pump
through the screen (B), filtering soil particles too large
to pass through and sending them back to the Chopper
blades.
3. The wash water is then cycled back through the spray
arms (C).
4. During the drain phase, a secondary pump flushes out
used wash water.
