Section 3. Basic Machine Operation; Section 4. Washer Controls Overview - Maytag Neptune MAH3000 Service Manual

SECTION 3. BASIC MACHINE OPERATION

The model MAH4000 and MAH5500A are similar to the MAH3000 washer, with the exception
being the MAH4000 and MAH5500A have a recirculation pump in series between the outer
tub outlet and the drain pump. When the water pressure switch becomes satisfied (Series 11
and later on the MAH4000 and all the MAH5500A), power is then applied to the recirculation
pump. The recirculation pump draws water from the bottom of the outer tub and circulates the
water up through the detergent hose, then into the top of the outer tub. By doing this, the
washer is able to provide a more even distribution of detergent throughout the wash load.

SECTION 4. WASHER CONTROLS OVERVIEW

The software of the MAH4000 and MAH5500A models is slightly different than the software
used in the MAH3000 washer. Fabric Selections on the control console were changed from
Cotton/Sturdy to Whites, Easy Care/Perm Press to Colors, Delicates remained the same.
Series 10 of the MAH4000 washer allowed the recirculating pump to be directly controlled by
the timer. (Figure 4-1)
