Use the "Manual Function Test" [as described on the electrical schematic sheet (6 918139)] 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.

3

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.

MDB9600AWQ, MDB8600AWW, MDB9600AWS, mdb8600awb, MDB8600AWQ specifications

The Maytag MDB8600AWQ, MDB9600AWQ, MDB9600AWB, MDB8600AWS, and MDB9600AWW are a series of high-performance dishwashers designed to bring efficiency and reliability to your kitchen. These models are equipped with a variety of features, technologies, and characteristics that make them stand out in the competitive appliance market.

One of the most notable features of these Maytag dishwashers is their powerful cleaning performance. They are equipped with the PowerBlast technology that targets tough stains and baked-on food, delivering a superior clean every time. This technology uses directed sprays and high-pressure jets to remove stubborn debris, ensuring your dishes come out spotless.

The MDB8600 and MDB9600 series also boast a large capacity, allowing you to load more dishes in a single wash cycle. This is made possible by the adjustable racks, which can be reconfigured to accommodate larger pots and pans or accommodate more items as needed. The third rack feature available in some models provides additional space for utensils and smaller items, optimizing your loading options.

Energy efficiency is another highlight of the Maytag dishwashers. Many models in this series are Energy Star certified, meaning they use less water and energy than standard dishwashers while providing exceptional performance. This not only makes them eco-friendly but also helps reduce utility bills.

Quiet operation is essential in any kitchen, and the MDB8600 and MDB9600 series excel in this regard. With noise levels as low as 47 dBA, these dishwashers operate smoothly without disturbing your household. The sound-dampening insulation and other design elements contribute to a quieter experience.

User-friendly controls are another attractive feature of these dishwashers. The intuitive electronic controls allow for easy selection of wash cycles and options, with various settings tailored to different load types and levels of soil. The delayed start feature gives you the flexibility to schedule wash cycles according to your convenience.

Durability is a key characteristic of Maytag appliances, and these dishwashers are no exception. Built with robust materials and a stainless steel tub, they are designed to withstand the rigors of daily use while maintaining their efficiency and effectiveness.

Overall, the Maytag MDB8600AWQ, MDB9600AWQ, MDB9600AWB, MDB8600AWS, and MDB9600AWW dishwashers deliver a combination of powerful cleaning, large capacity, energy efficiency, and durable construction, making them an excellent choice for any modern kitchen. With advanced technologies and thoughtful design, they promise to make dishwashing a hassle-free experience.
