Badge Isolator
Wireless Receiver
Cabinet Comp.
The badge isolator is located beneath the Controller on non-LCD models.
It provides electrical isolation between the badge and the DishDrawer by creating a physical barrier between the DishDrawer electronics and the badge while still passing power and button presses between the two. Thus, it functions as a low voltage component and allows the use of things like metal coated buttons.
In the case of integrated products, it also makes it impossible for an installer to receive a shock from the harness going to the badge while installing it, which is a requirement for standards approvals.
The wireless receiver receives signals from the remote control and passes them on to the controller.

Top Tub start button on doubles. Single tub start button on singles
Bottom Tub start button on doubles
If a receiver or the remote is replaced, the remote must be paired to the receiver before the integrated DishDrawer will function. This ensures that the remote will operate the correct drawer.
Press one of the buttons to make sure that the remote is powered, the ‘Transmit indicator’ should flash.
Ensure there is power to the product. If the receiver is connected correctly, the product should power up and play the startup sound. Place the remote on the wash program selector as shown.
If there are two single units in the home, be sure they are synched individually with the other drawer unplugged. Then unplug the first one while synching the second one. This to prevent one remote being synched to two DishDrawers.

28. Cycle Profiles
On Integrated models 4 things are done to
reduce moisture at the exhaust:
Notes: Draw attention to the removal of pre-wash cycle, the shorter Fast cycle, and the four changes to the dry cycle in integrated models.
Pre-Wash cycles have been removed in all cycles to better accommodate the use of tablet detergents.
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.

33. Diagnostics – Fault/Error CodesEC
Installation E3 E7 U1
Ask if there are any faults that any one has come across, and show how the information in the service summary walks them through the proper diagnostic steps. I always go over the “E9” just because it often stumps techs. I also point out again that fault codes can be read in the cycle lights on the top of the drawer.

57. 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.

58. 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.

59. 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 # must be used.
5. What 4 things prevent excess moisture from being exhausted from integrated models?
1. Final rinse temp reduced minute pause before fan comes on Higher fan speed. 4. Insulated vent hose.
