Viking Dishwasher Bottom Rack Hitting Door: How to Fix -... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) relies on door closure switches to initiate the wash cycle. Proper door closure ensures water remains contained and prevents leaks. Misalignment or obstruction affects these sensors and the overall operation. Voltage paths to the door latch and associated sensors need to be verified for proper function.

Symptoms:

The bottom dishwasher rack is hitting the inner door panel when closing, preventing the door from latching properly or causing damage to the rack or door. This may be accompanied by a scraping noise.

Possible Causes:

Bent or damaged bottom rack.
Misaligned rack rollers or slides.
Door hinges are loose or worn.
Obstruction (utensil, dish) preventing full door closure.
Door seal is damaged or improperly seated.
Dishwasher not level.

Solution:

1

Unplug the dishwasher or turn off the breaker at the breaker panel (120V AC circuit).
2

Inspect the bottom rack for bends or damage. Use pliers to straighten minor bends. Replace the rack if severely damaged.
3

Check the rack rollers and slides for proper alignment and smooth movement. Replace worn rollers.
4

Examine the door hinges for looseness. Tighten hinge screws with a Phillips head screwdriver. If the hinges are worn, replace them.
5

Remove any obstructions preventing the door from closing fully.
6

Inspect the door seal for damage or improper seating. Clean the seal with a damp cloth. Replace if damaged or torn.
7

Use a level to ensure the dishwasher is properly leveled. Adjust the leveling feet as needed with an adjustable wrench.

Safety Warning:

Disconnect power to the dishwasher before performing any repairs. The dishwasher operates on 120V AC, which can cause electric shock. Always follow Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Regularly inspect the dishwasher rack for damage. Avoid overloading the racks. Clean the door seal regularly. Ensure the dishwasher is level.

Expert Tip:

Many Viking dishwashers have a diagnostic mode. To access it, simultaneously press and hold the 'Start' and 'Cancel' buttons for 5 seconds. This mode can provide error codes related to door closure and rack position.
