Why Is My Viking Dishwasher Not Draining Water?

Despite its high-quality name and reputation, even a Viking dishwasher can fall victim to draining issues that occasionally plague other brands. Wondering why is my Viking dishwasher not draining water? Drain hose obstructions are a common cause that often requires a professional to remove the clog. Troubleshoot the most likely reasons your Viking dishwasher won’t drain and the right solutions to restore function.

4 Common Causes for a Viking Dishwasher Not Draining Water

Viking dishwasher troubleshooting consists of several common causes that can be resolved with a repair or proper maintenance. From a clogged filter to a blocked air gap, here’s how to pinpoint the problem.

Drain Hose Is Obstructed

Drain hose obstructions are one of the most common reasons for a Viking dishwasher not draining water. Loose food particles or debris can find their way inside this flexible plastic hose and cause blockages that prevent water from draining. A kinked hose could also restrict water as it exits the dishwasher, resulting in draining issues.

As long as it’s not damaged, a kinked drain hose can be untwisted to remove the kink and restore water flow. While a clogged hose can be resolved by removing the blockage, it’s a job best reserved for experienced DIYers or a professional service.

These steps provide general guidelines for removing drain hose clogs:

  1. Unplug the dishwasher.
  2. Consult your Viking dishwasher manual to determine how to best access the hose. Most are behind a lower front panel.
  3. Disconnect the hose from the drain pump.
  4. Inspect the hose for clogs, carefully removing any obstructions with pliers or a straightened wire hanger.
  5. If no clogs are visible, disconnect the hose from the disposal or air gap to look for blockages.
  6. If the clog isn’t reachable, the hose must be replaced.

Dirty Viking Dishwasher Filter

A clogged filter can also result in a Viking dishwasher drain problem. The filter screens out food particles to prevent them from clogging the drain pump or hose. However, the filter itself can become clogged with debris if not cleaned regularly. When this happens, water may not be able to drain through the filter. To prevent clogs, most dishwasher cleaning tips recommend monthly filter cleanings.

Here’s how to clean a Viking dishwasher filter:

  1. Take out the bottom rack.
  2. Remove the coarse strainer by squeezing the tabs on either side and lifting upward.
  3. Rotate the fine filter counterclockwise and lift up to remove.
  4. Rinse both components under running water. Use a plastic brush to gently scrub away stubborn debris.
  5. Replace the fine filter and turn clockwise to secure.
  6. Position the coarse strainer in place and push down to lock in the tabs.
  7. Replace the bottom rack.

Air Gap or Garbage Disposal Problem

If you have an air gap or garbage disposal, they likely share a common drain with the dishwasher. When either device becomes clogged, backups or leaks are common signs of a Viking dishwasher not draining water properly.

Before starting a wash cycle, always run the disposal for 1-2 minutes to clear it of any lingering debris. If you have an air gap, regular cleanings can prevent blockages. To clean the air gap, remove the protective cover and scoop away any debris with a paper towel.

Viking Dishwasher Drain Pump Failure

If all else fails to resolve drainage issues, it’s possible that the dishwasher’s drain pump has failed. This motorized component uses an impeller to expel water through the drain hose. When the motor fails, the impeller won’t be able to force water through the hose and it will remain in the dishwasher. If multimeter testing confirms pump failure via a lack of continuity, the pump must be replaced by a professional dishwasher repair service.
