Introduction
All KitchenAid Products are well designed. Normally they will give continual use year after year without service attention.
Records have been maintained to determine and correct, through improved design, any troubles that might possibly
develop. An effort has been made in preparation of this manual to cover them all.

Electrical Requirements
This food processor is designed for use with 120 VAC, 60 Hz (240 VAC, 50 Hz International) only. It has a grounded plug
and should not be modified in any way. Do not use an extension cord or an adapter with this food processor.
A short power supply cord is provided to reduce the risks resulting from becoming entangled in or tripping over a longer
cord. If the power supply cord is too short, have a qualified electrician or service technician install an outlet near the area
where the food processor will be used.
Important Safeguards
Ensure the KitchenAid®service technician is aware of the operating safeguards recommended to the customer:
1. Read all instructions in the KitchenAid®Food Processor Service Guide to Professional Results booklet.
2. Close supervision is necessary when any food processor is used by or near children.
3. The food processor has been U listed for household and commercial use.
4. To protect against electrical shock, do not immerse cord, plugs, or food processor housing in water or other liquid.
5. Do not operate any food processor with a damaged cord or plug or after the food processor has malfunctioned or has
been damaged in any manner.
6. Unplug the food processor from the outlet before cleaning.
7. Do not let the cord hang over the edge of a table or counter or touch hot surfaces.
8. Do not use an extension cord.
9. The use of accessories not recommended by KitchenAid®may result in fire, shock, or injury to persons.
10. Do not use the food processor outdoors.
11. Do not place the food processor on or near a hot gas or electric burner or on a heated oven.
12. Do not use the food processor for other than its intended use.
13. Do not use the food processor without the work bowl cover in place while in operation.
14. Do not clean the work bowl/cover with harsh cleaners, steel wool pads or other abrasive material.

List of Tools Required
The following tools are necessary to service the KitchenAid®Food Processor.
Dead Blow Hammer
Phillips Screw Driver
Large Flat Head Screw Driver
Small Flat Head Screw Driver
Soft Work Surface (soft towel or foam matting)
Volt/Ohm Meter or Digital Multi-meter
NOTE: Power drivers are not recommended for servicing the KitchenAid®Food Processor.
The following equipment will greatly assist the technician in servicing the KitchenAid®Food Processor:
Low pressure compressed air to remove debris from food processor/components.
Clean rags/shop towels
Cushion the service area to keep from scratching the food processor or damaging the controls. A clean shop
towel or a folded paper towel will usually work well for this purpose.
Testing the Food Processor
The service technician will have to test the performance of the food processor to identify and diagnose the problem.
Normal electrical testing techniques, using a volt/ohm meter, are sufficient to test the food processor electrical
components.
NOTE: Refer to the PROBLEM GUIDE in this manual while performing any test.
Review any documentation accompanying the faulty food processor.
Perform a ground continuity test and a hi-pot test prior to plugging the food processor into an electrical outlet.
Prior to disassembling the food processor, plug it into an electrical outlet and perform a function test. Test the
switches, speed selections, etc. for proper operation and to troubleshoot for the problem.
If the unit does not run when plugged in, make sure that the work bowl and lid are properly installed and that the
pusher is in place. Proper installation of the work bowl, lid and pusher are essential for the safety switch interlock
system to function. The work bowl interlock can be verified by assembly of the bowl, lid and pusher while off of the
base unit.

- 5 -
Check the bottom of the work bowl handle for interlock action. Proper interlock operation can be determined as shown
below.
Working and non-working bowl safety interlock
After it is determined that the work bowl interlock is working properly, the safety switch can be tested by the following
procedures:
Lock the work bowl to the base of the unit.
Put the lid with the pusher on the work bowl and lock it into place.
With the unit unplugged, turn the power switch to the “ON” position.
Refer to Fig. 2 and measure the resistance across the power plug (L1 & Neutral for 115~120v. domestic units or
L1 & L2 for 230~240v international units).
If the switch is good, the resistance will be very low (typically less than 10Ω).
If the switch is not working (bad), the resistance will be very high (higher than 1.5 MΩ).
Safety Switch test measurement.
After troubleshooting, use the SERVICE PROCEDURES to replace any faulty component.
Working - Interlock extended with lid on bowl
and pusher fully seated.
Non-working - interlock not extended with lid
on bowl and pusher in place.

Service Procedures
This manual is written as a step-by-step guide to disassemble and reassemble the KitchenAid®Food Processor to gain
access to the systems within the unit that are in need of repair. For models covered in this manual, refer to the index
page.
Most of the KitchenAid® Food Processor components are contained within the food processor motor housing. Perform the
Component Access Procedure (below) to gain access to the food processor components.
NOTE: When removing self-tapping screws from any plastic or metal housing, the filings created will be scattered onto
adjoining components. Prior to performing any reassembly procedure, make sure to remove all the filings using clean
rags, low-pressure compressed air, etc.
Use of the Troubleshooting Quick Reference Guide (Appendix B) will aid in determining what steps are necessary for
repairing the unit. Not all steps will be needed for some of the repairs so it is important to consult the Troubleshooting
Quick Reference Guide first.
Appendix C lists all of the KitchenAid® Food Processor screw torques required for proper reassembly of the unit.

components:
1. Unplug the power cord.
2. Remove the work bowl and using a screw driver or a hammer lay across the top of the housing. Use a large flat head
Screw Driver to pry the slicing disc sleeve off.(Fig. 1)
