General Theory of Operation
Maytag Chopper Wash System
Maintenance Free Chopper System
A 4-Blade stainless steel chopper pulverizes food, preven๎†Ÿng
par๎†Ÿcles from plugging the wash system and spray jets,
providing op๎†Ÿmal cleaning without the need to prerinse
No more scraping plates. The 4-blade stainless steel chopper
disintegrates the food par๎†Ÿcles that come o๎„ซ your dishes so
they donโ€™t end up recircula๎†Ÿng and s๎†Ÿcking to your dishes and
glassware.
How Chopper Works (See Figure 1)
1. Water and food par๎†Ÿcles ๎…‡ow through the coarse ๎„ฎlter
then are disintegrated by the Chopper blades (A).
2. An impeller pulls soiled water into the wash pump
through the screen (B), ๎„ฎltering soil par๎†Ÿcles too large
to pass through and sending them back to the Chopper
blades.
3. The wash water is then cycled back through the spray
arms (C).
4. During the drain phase, a secondary pump ๎…‡ushes out
used wash water.
Figure 1 - Chopper Wash System
n Maytagยฎ dishwashers feature the most
powerful motor on the market, so you
can be sure what you put in comes out
clean.

DIAGNOSTICS & TROUBLESHOOTING
For Service Technician Use Only
Voltage Measurement Safety Information
When performing live voltage measurements, you must do the following:
n Verify the controls are in the off position so that the appliance does not start when energized.
n Allow enough space to perform the voltage measurements without obstructions.
n Keep other people a safe distance away from the appliance to prevent potential injury.
n Always use the proper testing equipment.
n After voltage measurements, always disconnect power before servicing.
IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics
ESD problems are present everywhere. Most people begin to feel an ESD discharge at approximately
3000V. It takes as little as 10V to destroy, damage, or weaken the main control assembly. The new
main control assembly may appear to work well after repair is ๎‚ฟnished, but a malfunction may occur
at a later date due to ESD stress.
n Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted
metal in the appliance
-OR-
n Touch your ๎‚ฟnger repeatedly to a green ground connection point or unpainted metal in the
appliance.
n Before removing the part from its package, touch the anti-static bag to a green ground
connection point or unpainted metal in the appliance.
n Avoid touching electronic parts or terminal contacts; handle electronic control assembly by
edges only.
n When repackaging main control assembly in anti-static bag, observe above instructions.
IMPORTANT SAFETY NOTICE โ€” โ€œFor Technicians onlyโ€
This service data sheet is intended for use by persons having electrical, electronic, and mechanical
experience and knowledge at a level generally considered acceptable in the appliance repair trade.
Any attempt to repair a major appliance may result in personal injury and property damage. The
manufacturer or seller cannot be responsible, nor assume any liability for injury or damage of any
kind arising from the use of this data sheet.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Failure to do so can result in death or
electrical shock.
Replace all parts and panels before operating.
DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.

*APF purges are allowed in APF enabled intervals.
APF Purge: 2 drain pulses, 5 sec. FILL and
DRAIN๎€€<๎€€then 5 sec. FILL.
NOTE: OWI has themistor built in (see below)
1 To invoke the Diagnostics Cycle, perform the following while in
standby:
โ–  Press START/RESUME to wake up the control panel.
โ– 
Press any 3 keys in the sequence 1-2-3-1-2-3-1-2-3 with no more
than 1 second between key presses.
โ–  The Service Diagnostics Cycle will start when the door is closed.
โ–  To rapid advance 1 interval at a time, press START/RESUME.
Rapid advancing may skip sensor checks๎€Œ as some checks
require 2 complete intervals.
NOTE: While in the Diagnostic Cycle, the Start/Resume feature is
turned off (for example, Auto Resume after door interrupts) and the
Start/Resume key becomes an interval advance key.
โ–  Invoking Service Diagnostics clears all status and last run
information from memory and restores defaults
โ–  Drain and wash motors will pulsate on and off
โ–  Last run cycles and options๎€€ARE returned to default.
โ– 
Reset OWI calibration values to the default values.
โ–  Forces OWI (Optical Water Indicator) calibration cycle on next
customer cycle.
NOTE: Calibration cycle may add additional rinses prior to the final
rinse to assure clear water and then calibrates the OWI during the fill
at the beginning of the final rinse.
โ–  Operating state returns to standby upon completing or
terminating the service diagnostics cycle.
โ–  Reference โ€œService Diagnostics with Error Codesโ€ section for
details.
2 Turn on all LEDs immediately upon receiving the entry sequence (even
if the door is open) for 5 seconds as a display test. Turn off all LEDs for
1 second prior to reporting customer error history.
3 Press HI TEMP in this interval to clear customer error history. If the Hi
Temp key does not respond, the control panel is in sleep mode. Open
and close the door to wake up the control panel, and then press HI
TEMP to clear error history.
4 OWI (Optical Soil Sensor) checks -
โ–  Check OWI sensor for the presence of water during the interval
14, and turn on the Clean LED in interval 13 if water detected.
โ–  Check OWI for the presence of air during drain interval 5๎€Œ and
turn๎€€on the clean LED in interval 4 if air detected.
โ–  Check OWI sense for the presence of bulk soil during pause
interval 9; execute APF, and turn on clean LED in interval 8 if bulk
soil detected.
5 The
rmistor (temperature sensor) checks - turn clean LED on if
thermistor is in its normal temperature range (32ยฐF to 167ยฐF [0ยฐC to

Service Diagnostics with Error Codes
Entry sequence: Press any 3 keys in the sequence 1-2-3-1-2-3-1-2-3 with no more than 1 second between key presses.
NOTE: Some models have replaced the โ€œCLEANโ€ LED with โ€œCOMPLETE.โ€
If no error, โ€œCleanโ€ LED stays on for 5 seconds or display shows โ€œF-โ€ or โ€œE-โ€.
NOTE: Once error codes are extracted, refer to the โ€œService Error Codesโ€ table to diagnose and correctly resolve the root cause condition.
