Whirlpool MAH3000 service manual Bleach Dispense, Redistribution, Suds Detection

If the Start/Pause key is pressed during the wash cycle the washer shall stop all the functions of the washer, placing the washer in the Idle Mode. The Start/Pause LED will flash indicating the pause mode. The current place in the cycle will be saved.

If the Start/Pause key is pressed the door will not be unlocked until the spin speed is 0 rpm.

If the Start/Pause key is pressed while flashing (in pause mode), the machine shall return to the start of the cycle step when paused and the time displayed be recalculated to the start of the cycle step. The Start/Pause LED will stay on whenever the machine is running in a cycle. Note: The door must be closed prior to resuming the cycle.

BLEACH DISPENSE

The Bleach Fill occurs 2 minutes prior to the end of the wash portion of the cycle. A bleach fill consists of turning the bleach water valve and the appropriate fill water valve(s) on until the water reaches high water level or for 24 seconds, whichever comes first. This is to ensure the bleach is used completely during this wash. The fill temperature during the Bleach fill shall be based on the user selections. If stain cycle is selected then bleach fill and final rinse are based on user selections. If stain cycle is not used, then only the final rinse is affected.

REDISTRIBUTION

As the machine is accelerating into spin, if it detects that the clothes load is unbalanced and would cause excessive vibration, it will decelerate and tumble the clothes in an attempt to redistribute them in a more uniform manner so that vibration is reduced.

The machine control commands a distribution profile speed ramp from 0 rpm to 85 rpm at the beginning of each

high speed (above 100 rpm) spin. When the washer reaches 85 rpm, the machine control monitors the Tach Input to determine if the speed varies through one revolution of the spinner basket. If it senses a high enough variation in speed (suggesting an out-of-balance condition in the clothing load), it will drop the spinner speed to 0 rpm and force a short reverse tumble to redistribute the clothing load before resuming the spin. If any of the out-of-balance switches trip and open the out-of-balance input circuit at a speed below 500 rpm, the machine control will also drop the speed to 0 rpm and force the reverse tumble to redistribute the clothing load before resuming the spin.

SUDS DETECTION

The suds detection feature tries to eliminate excessive suds during the main wash or rinse cycles. Suds detection is disabled during a stain cycle tumble pattern.

If suds are detected, the estimated time left on the wash cycle will be modified to account for 4 additional rinses.

The washer will try twice in early spins and 21 times when in the final spin.

LCD Washer: If four out of seven cycles have suds detected, “Too many Suds detected” should be displayed on the screen.

LED Washer: If suds are still detected, the “rinse” LED shall blink, 3 seconds on, 3 sec- onds off and "sd" will be displayed.

TUMBLE FLUSH (Two types of flush) Wash tumble is a higher tumble speed than normal while the machine is filled with water. The purpose of this function is to clean the machine. Rinse tumble flush is performed during the final rinse to reduce the chance of suds creation.
