Installation – Bad Installs
If an extension is required, extension kit 525798 must be
used, not connecting a garden hose to the “Y” connector, as
seen here!
This one was drained
through the floor with no
hi-loop and the “Y”
connector was folded
over. Complaint? Not
draining….

Review
Components Review
1. How can you tell the difference between a badge isolator and a wireless
receiver?
The wireless receiver has the part number showing on the single label.
2. Does the lid actuator still plug into the mains filter board on the Ph 7 models?
No, but it can be unplugged right at the motor.
3. Is the same Controller used in all DishDrawers?
No. The Controllers are distinct to each model. Use the product code to
order.
4. How does the DishDrawer know when a drawer is opened or closed?
An infrared light is transmitted from the controller though the light pipe on the
side of the tub, through a prism mounted in the chassis trim, then back through
the other light pipe to the receiver
5. What is the most important number to use when ordering parts?
The Product Code, which is a 5 digit number, specific to that particular
version of the model.
®
Diagnostics Review
1. How do you enter Diagnostics on a Ph 7 DishDrawer with an LCD display?
The same as on previous models; with the Drawer off, Press and hold the
“Lock” button and then the “Start/Pause” button until all the icons appear.
2. What are 3 key changes to Ph 7 Diagnostics?
“F” codes are now “E” codes, Sub codes have been added and audible alerts
when testing a faulty component in Hardware Output.
3. What does an E9 fault indicate?
It is a microcontroller fault, usually related to the badge isolator, detergent
diverter or harness, mains filter board, or the main controller.
4. Which components can be tested right at the controller?
The element components, both lid motors, detergent diverter and rinse aid
pump, fill valve, fan, and all phases of the motor
5. What cycle should be run after any repair?
The Fast Cycle, which tests the lid motors, fill valve, detergent diverter,
wash motor, element, drain motor and drying fan.
®
Installation Review
1. What problems can occur because of a DishDrawer not being installed
properly?
Wash problems, Leaking, Draining, Drawer closure, and many more.
2. What must the minimum height of the high-loop be?
The high-loop must be a minimum of 29 1/2 “ from the floor.
3. What is the minimum amount of screws that must be used to fasten the
DishDrawer?
At least two screws on one side.
4. Can the drain line be extended?
Yes, but part # 525798 must be used.
5. What 4 things prevent excess moisture from being exhausted from integrated
models?
1. Final rinse temp reduced. 2. 30 minute pause before fan comes on.
3. Higher fan speed. 4. Insulated vent hose.
