COMPONENTS

4.1

Tank with base and sump

4.1.1 Tank, base and sump assembly
The tank, base and sump are welded together and aren't
available as a service part. If plastic cable holders, part holders
and screw holes are damaged or stripped, the entire dishwasher
must be replaced.
4.1.2 Rear leveling foot
The rear leveling foot can't be adjusted from the front – the rear
foot is the same as front feet and is adjusted the same way. The
base has provision for two rear feet in the rear corners, but the
center foot factory mounting should be used.
Factory feet positions have provisions for set screws (in
installation parts bag). Outside rear positions don't have set
screw positions and shouldn't be used.

Heated circulation pump (heat pump)

There's no flow-through heater, flow switch or Hi-Limit cutout –
the circulation pump has a flow-through heated cylinder. The 120
VAC, 1200W heater cylinder provides more heating surface area
and heats water slightly more quickly than traditional flow-through
heating elements (~ 2ºF/minute). The circulation pump (portion)
has a 3-pole BLDC motor controlled by the power (control)
module. The dishwasher won't run if the heat pump is
disconnected or disabled.
