Maytag Dishwasher MDB7759AWS0 Will not fill with water or doesn't fill with water

The Dishwasher Water Inlet Valve is an OEM part for Whirlpool dishwashers that is responsible for controlling the flow of water into the dishwasher at the start of each wash cycle. The water inlet valve opens to allow water to enter the dishwasher and then closes to ensure the correct amount of water is used during the cycle. Redesigned: Valve mounts directly on the frame and no longer includes or requires the mounting bracket.

Symptoms of a bad Dishwasher Water Inlet Valve include:

• Inadequate water filling the dishwasher.
• Overfilling, which can cause leaks and potential water damage.
• Unusual noises coming from the valve area.
• The dishwasher not starting.

Causes of a bad water inlet valve can vary from mineral buildup from hard water, which can block the valve, to mechanical failure or wear and tear over time. Electrical issues can also affect the valve's operation, preventing it from opening or closing properly.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

The Float Switch Kit is an OEM part for Whirlpool dishwashers. It includes the float and the switch mechanism that monitors and controls the water level inside the dishwasher. The float switch ensures that the dishwasher does not overfill by signaling the water inlet valve to shut off the water supply once the appropriate level is reached.

Causes of a bad float switch can include debris or mineral buildup, wear and tear over time, or electrical failures within the switch mechanism. A malfunctioning float switch can lead to water overfilling, which may cause leaks and inefficient washing performance.

Symptoms of a bad float switch kit include:

• Dishwasher overfilling with water
• Water leaks during operation
• Dishwasher not filling with enough water
• Error codes related to water levels

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Overfill control.

This overfill float and shaft assembly monitors the dishwasher's water level. As the tub fills, the float rises and triggers the float switch to shut off the inlet water, helping prevent overfilling and leaks.

• Senses tub water level and moves up/down with the water
• Activates the float switch to stop filling at the correct level
• Helps protect against overfill-related leaks
• Common symptoms include: won't fill (float stuck up), continuous filling/overfilling (float stuck down or damaged), or float not moving freely

• Disconnect power and turn off the water supply before servicing
• Lift the old float straight up from inside the tub; access the underside (behind the toe panel) as needed to release the shaft from the float switch lever
• Install the new shaft through the guide and onto the switch lever; seat the float so it moves freely
• Verify smooth float movement and test a fill cycle while checking for leaks
