Electrolux EDW7505HPS, EIDW6405HT Wiring Diagram
a
Pump Assembly
The pump assembly is driven by a permanent
split capacitor motor. When looking at the output
shaft, rotation is in the counterclockwise direction
at 3300RPM when driven by 120V 60Hz AC
signal. The motor drives a pump which supplies
100% filtered water at the rate of approximately
19 GPM to all three spray arms at once.
Draining is accomplished by using a small
seperate synchronous drain pump mounted to
the sump. The drain pump is connected to the
sump by a small rubber hose and two mounting
points.
Component Error LED Indication
The drain valve is connected to the drain pump
by a rubber hose and is mounted to the
dishwasher base. The drain valve maintains
pressure in the pressurized fine filter. The
intermediate drain hose is attached by a worm
gear clamp to the discharge end of the drain
valve.
The drain hose must have a loop at a minimum
height of 32 inches in order to ensure proper
drainage.
The main pump is removed by disconnecting
both attached clamps and hoses, removing the
three screws that secure the motor base to the
dishwasher base, unlatching the leak detector,
and disconnecting the wiring harness
connections to the pump assembly.
To gain access to the Control Housing
Assembly, remove kickplate assembly. LED
indicates which component is the source of
the error.
Standard Dry Air Flow
When the control advances to the “dry” portion of
the cycle, the lower fan located in the Lower
Drying Duct Assembly is activated. Then, the
Vent Assembly located in the top right corner of
the tub is activated. The vent fan draws in the air
from outside the tub forcing the hot, humid air out
the Side Drying Duct Assembly and into the
Lower Drying Duct Assembly. Cool dry outside
Detergent and Rinse Aid Dispenser
The detergent and rinse aid dispenser is a one
piece component consisting of a molded
detergent cup and a built-in rinse aid dispenser.
The detergent cup has a spring loaded cover
and the rinse aid dispenser has a removable
cover.
Liquid rinse aid is added to the dispenser up to
the fill line indicator. The amount of rinse aid
released can be adjusted by turning the arrow
indicator from one, being the least amount, to
four, being the greatest amount.
Tub Gasket
The door gasket is pressed into the tub channel
for an interference fit. To install the gasket:
1. Apply a small bead of silicone sealant
(Dow 732) all of the way around in the gasket
channel along the back surface.
2. Locate the center mark on the gasket and
press into place.
3. Press the gasket across the header using
your thumb.

air is mixed with hot, humid air existing the tub
in the Lower Drying Duct Assembly. This lowers
the temperature and humidity of the air exiting
the unit through the toe and kickplate. The
addition of cooler, dryer outside air helps to
speed evaporation of water from the hot dishes.
To replace dispenser:
• shut off electricity,
• remove outer door (there are 6 screws to
remove, starting at the top of the door remove
the first, fourth and fifth screws per side)
• remove middle door and foam barrier (there
are 4 screws into the hinge arms, lower portion
from the front, and 2 screws (1 per side, third
screw from the top),
• disconnect wiring to the dispenser,
• remove 6 screws and 2 brackets,
• remove the dispenser,
• reassemble using the new dispenser in
the reverse order of above.
4. Press the gasket while stretching around
the corners.
NOTE: There should be no wrinkles or
puckers in the corners.
5. Place the gasket end at the bottom and
then press the gasket in from the bottom up.
