Cycle Profiles
• Pre-Wash cycles have been removed in all cycles to better accommodate the use of tablet detergents.
On Integrated models 4 things are done to
reduce moisture at the exhaust:
®
1. The final rinse temperature is reduced
2. There is a 30 minute dwell period before the drying fan comes on.
3. The drying fan blows faster
4. The vent hose is insulated.
Diagnostics
4 Key Steps to Diagnosing Problems
1. Talk to the customer.
2. Check for fault codes.
3. Test Components in Hardware Output.
4. Check Resistance of Components at Controller.

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….

Components Review1. How can you tell the difference between a badge isolator and a wireless receiver?
2. Does the lid actuator still plug into the mains filter board on the Ph 7 models?
3. Is the same Controller used in all DishDrawers?
4. How does the DishDrawer know when a drawer is opened or closed?
5. What is the most important number to use when ordering parts?
The wireless receiver has the part number showing on the single label.
No, but it can be unplugged right at the motor.
No. The Controllers are distinct to each model. Use the product code to order.
The Product Code, which is a 5 digit number, specific to that particular version of the model.
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
®
Diagnostics Review1. How do you enter Diagnostics on a Ph 7 DishDrawer with an LCD display?
2. What are 3 key changes to Ph 7 Diagnostics?
3. What does an E9 fault indicate?
4. Which components can be tested right at the controller?
5. What cycle should be run after any repair?
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.
“F” codes are now “E” codes, Sub codes have been added and audible alerts when testing a faulty component in Hardware Output.
It is a microcontroller fault, usually related to the badge isolator, detergent diverter or harness, mains filter board, or the main controller.
The element components, both lid motors, detergent diverter and rinse aid pump, fill valve, fan, and all phases of the motor
The Fast Cycle, which tests the lid motors, fill valve, detergent diverter, wash motor, element, drain motor and drying fan.
®
Installation Review1. What problems can occur because of a DishDrawer not being installed properly?
2. What must the minimum height of the high-loop be?
3. What is the minimum amount of screws that must be used to fasten the DishDrawer?
4. Can the drain line be extended?
5. What 4 things prevent excess moisture from being exhausted from integrated models?
Wash problems, Leaking, Draining, Drawer closure, and many more.
The high-loop must be a minimum of 29 1/2 “ from the floor.
At least two screws on one side.
Yes, but part # 525798 must be used.
1. Final rinse temp reduced. 2. 30 minute pause before fan comes on. 3. Higher fan speed. 4. Insulated vent hose.
