Washer Help Mode; Diagnostic Codes - Maytag MAT12PDSA Technical Information

Component Testing Procedures
To avoid risk of electrical shock, personal injury or death; disconnect power to washer before servicing, unless
testing requires power.

WASHER HELP MODE

The mode is entered by depressing Permanent Press keypad while in special pricing option Step 2.XX(or while dAS
displays if operation with Maytag Data Acquisition setup). In help mode , the Woolens keypad can be used to
advance through three help codes(displayed as 1h.XX, 2h.XX, and 3h.XX). Pressing Delicates & Knits keypad
while any of the help codes are displayed clears the three help codes. The help modes are followed by the Energy
Saving indication screen (displayed as hE.ES), the software version, and finally the water temperature sensing
(displayed as Exxx). Press the Permanent Press keypad at anytime to exit help mode.
The Energy Savings indication screen (hE.ES) and temperature sensing screen (Exxx) will only be displayed if the
water is configured for energy saving operation. The water temperature sensing screen(displayed as Exxx) is not a
measure of water temperature in °F, but higher numbers do correspond to higher temperature water.
