!

powerTo avoid risk of electrical shock, personal injury, or death, unless testing requires power.

1

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.)

2> 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.

3Perform 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.

MDB5600AWS, MDB5600AWQ, MDB5600AWW, MDB5600AWB, JDB4000AWB specifications

Maytag's line of dishwashers includes several popular models, known for their reliability and performance in the kitchen. Among these, the JDB4000AWQ, JDB4000AWB, MDB5600AWW, JDB4000AWS, and JDB4000AWW stand out due to their range of features, technologies, and user-friendly characteristics.

The Maytag JDB4000 series, including the JDB4000AWQ and JDB4000AWB, is designed to provide efficient cleaning while maintaining a stylish appearance. One of the key features of these models is their PowerBlast technology, which utilizes high-pressure spray jets to target tough food particles and stains, ensuring nothing is left behind. This technology enhances the cleaning performance, making it easier to handle even the dirtiest dishes.

All models come equipped with a durable stainless steel tub, which not only improves cleaning performance but also offers resistance to odors and stains, ensuring that your dishwasher stays fresh over time. The stainless steel construction also helps with improved drying performance, as it retains heat better than plastic options.

The MDB5600AWW model introduces additional features, such as a third rack option. This allows for increased loading capacity, giving users more flexibility in organizing their dishes. The adjustable upper rack allows for taller items to fit in the lower section, enhancing the user experience and maximizing space.

The noise level of these dishwashers is particularly noteworthy, as they operate at a quiet decibel level, enabling users to run them without disruption during family time or entertaining guests. The Quiet Series sound insulation technology ensures that the noise produced during cycles is minimal, making them suitable for open-concept living spaces.

Sustainability is also a focus, with these models designed to be energy efficient, helping users save on their utility bills while reducing their environmental impact. The Energy Star certification reflects these efforts, ensuring they meet strict efficiency guidelines.

In summary, the Maytag JDB4000AWQ, JDB4000AWB, MDB5600AWW, JDB4000AWS, and JDB4000AWW combine modern features, innovative technologies, and practical characteristics, making them appealing choices for households looking for reliable dishwashing solutions. Their robust performance, flexible loading options, and energy efficiency make them versatile additions to any kitchen.
