DRYER DIAGNOSTIC MODE

This mode is entered by depressing DELICATES for one second while in any of the set-up codes one through six (or while dAS displays if operating with Maytag Data Acquisition setup) or with a diagnostic code present. Diagnostic codes are cleared on entry and all display segments should flash. If a diagnostic code persists, it must be corrected before the diagnostic cycle may be executed.

All Single Load Models:

With all segments flashing, the diagnostic cycle is started by depressing the PERMANENT PRESS key pad. The cycle consists of seven minutes of heat and 1 minute of cooldown. The WHITES & COLORS key pad will increment the diagnostic cycle minutes up to 99, then roll over to 2 minutes. The DELICATES key pad will cancel this cycle and exit the diagnostic mode.

Stacked Models Only:

There are 2 procedures to initiate cycle activity from diagnostic mode for these models:

1.Upper Dryer Field Diagnostic Cycle – With the entire display flashing, the cycle is started by pressing the UPPER DRYER PERMANENT PRESS key pad. The cycle consists of seven minutes of heat and one minute of cool down. The UPPER DRYER WHITES & COLORS key pad will increment the diagnostic cycle minutes up to 99, then roll over to 2 minutes. Pressing the LOWER DRYER DELICATES key pad will cancel this cycle and exit the diagnostic mode.

2.Lower Dryer Field Diagnostic Cycle – With entire display flashing, the cycle is started by pressing the LOWER DRYER PERMANENT PRESS key pad. The cycle consists of seven minutes of heat and one minute of cool down. The LOWER DRYER WHITES & COLORS key pad will increment the diagnostic cycle minutes up to 99, then roll over to 2 minutes. Pressing the LOWER DRYER DELICATES key pad will cancel this cycle and exit the diagnostic mode.

Dryer Help Mode
