Use the "Manual Function Test" as described on the electrical schematic sheet to

check components before opening the door to perform continuity testing or replacing parts.

To check continuity from ends of power leads to control board through door switches

(A white plastic latch must be inserted in the latch assembly for this test.)

>With one ohm meter lead connected to the white (neutral) power lead, you should have continuity at stake lugs 10 & 11.

>With one ohm meter lead connected to the black (line) power lead, you should have continuity at stake lugs 3 & 4, and pin # 8 on connector J5.

Perform the resistance checks on the component(s) in question at the locations shown on the chart.

*Select Models Only.

**Nominal value for ohms of electrical resistance of component only. These values will vary slightly due to the additional resistance of the wire harness. Greater variation can occur if the component is still warm from being energized during testing.

***A resistor in the control board wired in parallel will result in an approximate reading of 4.0 k ohms with connector J5 plugged in.

The Maytag MDB8751AW, MDB8951AW, MDBM755AW, MDB7751AW, and ADB3500AW dishwashers represent a collection of reliable and efficient kitchen appliances designed to streamline the dishwashing process while delivering exceptional cleaning results. Each model showcases essential features and innovative technologies tailored to meet the needs of modern households.

One of the standout characteristics of these Maytag dishwashers is their powerful wash performance. Equipped with a robust stainless steel tub, these models enhance drying efficiency and help prevent the buildup of odors. The high-pressure spray jets provide a thorough clean, ensuring that dishes, pots, and pans come out spotless every time.

Another key feature is the PowerBlast feature available in select models. This technology uses intense sprays from specialized jets combined with high temperatures to eliminate tough messes like baked-on food and stubborn stains, making it ideal for heavy cleaning loads. Moreover, the Soil Sensor technology automatically detects how dirty the dishes are and adjusts the wash cycle duration for optimal cleaning performance.

Energy efficiency is also a notable attribute across these dishwashers. Many models include Energy Star certification, indicating they consume less water and electricity compared to standard units, allowing households to reduce their environmental impact and save on utility bills.

In terms of versatility, the Maytag MDB series offers adjustable and foldable tines in the upper and lower racks. This flexibility allows users to customize the interior space to accommodate larger items seamlessly while maximizing loading capacity. Additionally, the third-level rack provides an extra space for utensils, ensuring more efficient use of the dishwasher's interior.

Ease of use is a priority in these models, with features such as the intuitive control panel and delay start option that allows users to run the dishwasher at a more convenient time. Noise levels are also minimized with sound insulation technology, making these dishwashers suitable for open-concept living spaces.

Overall, the Maytag MDB8751AW, MDB8951AW, MDBM755AW, MDB7751AW, and ADB3500AW dishwashers showcase a blend of powerful cleaning technologies, efficient energy use, and user-friendly features, making them excellent choices for families looking for dependable, high-performance dishwashing solutions.
