    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.
