Service Diagnostics and Procedures
Circulation Motor Disassembly (cont.)
The image below shows the filter inlet hose to the
sump disconnected. The arrow points to the “Filter
Clean” inlet in the sump. Regardless of the position
of the diverter, water is directed to this tube.
The image below shows the hose disconnected
from the pump.
Note: that there is a white motor grommet over
the pump opening. Make sure it is back in place
and bottom edge is facing base pan before
reassembly. (The second right image on page 40
shows proper position of grommet).
Water Heater Disassembly
The dishwasher uses a flow-through heater that will
heat the water as it passes though the center of
the heater. In order to remove, unplug the 2-wire
connector that
supplies power to
the heating
element and the
ground wire which
connects to a
spade terminal
on the heater
housing. Image
to left shows the
connections.
Next, disconnect the two clamps that hold the
heater assembly to both the sump outlet (Arrow 1)
and circulation pump inlet (Arrow 2) shown below.
The heater can now be removed for service. You will
need to transfer the two 1-1/2” (3.8 cm) OD hoses to
the new heater assembly. The element is a
120-volt,12 ohm, 10 amp, 1200 watt draw. It is
controlled
from P12
(gray) to
Neutral on
the main
terminal
block.
