Viking Dishwasher Not Draining — Causes & Step-by-Step Fix
A Viking dishwasher that leaves standing water in the tub at the end of a cycle is one of the most common dishwasher faults. Specifically, the majority of drain failures results from a clogged filter — a task that takes about five minutes to resolve yourself.
In addition, if any step seems unsafe or unclear, stop and call a certified technician. As a result, you protect both yourself and your appliance from further damage.
Step-by-Step Instructions
First, read all the steps before you begin. After that, gather the tools you need and follow the process in order:
- Step 1: Clean the filter assembly — Viking dishwashers use a manual-clean filter at the bottom of the tub that must be cleaned regularly. Specifically, a clogged filter is the most common cause of Viking dishwasher drain failures. How to clean: 1. Furthermore, remove the lower rack. Additionally, 2. As a result, locate the cylindrical filter at the center of the tub floor. 3. Therefore, twist counter-clockwise and lift out. Moreover, 4. However, rinse under running water, scrubbing gently with a brush to clear food particles and grease. 5. In addition, check inside the filter housing for any glass shards or bone fragments. Consequently, 6. For this reason, reinstall by twisting clockwise until locked. If the filter is clean and the dishwasher still won't drain, continue to the next steps.
- Step 2: Run a drain-only cycle — Initiate a drain-only sequence: on most Viking dishwashers, press and hold the Start/Cancel or Cancel button for 3 seconds. Specifically, listen carefully during the drain phase: • Steady, forceful pumping sound = pump is running. • Silence during the drain phase = pump motor has failed. Furthermore, • Buzzing with no water movement = pump impeller has jammed (often by a glass shard or bone fragment lodged in the pump body). Additionally, document what you hear for your technician.
- Step 3: Check the drain hose — If the pump is running but water remains, check the drain hose: • Inspect the hose behind the dishwasher for kinks. Specifically, • Verify the hose connection at the sink drain or garbage disposal is not blocked. • If connected to a garbage disposal, confirm the disposal knockout plug has been removed (common if the disposal was recently installed). Furthermore, • Ensure the drain hose has a high-loop configuration to prevent siphoning.
- Step 4: Professional pump replacement if needed — If the filter is clean, the drain hose is clear. Additionally, the pump is silent or produces only buzzing during a drain cycle, the drain pump motor requires professional replacement.

Frequently Asked Questions
How often should I clean the Viking dishwasher filter?
Viking recommends cleaning the filter monthly under normal use. Specifically, in households with heavy use (daily cycles) or hard water, clean every two to three weeks. A clogged filter causes drain failures, reduces cleaning performance. Additionally, can allow water to sit in the bottom of the tub between cycles, creating odors.
Why is there water in the bottom of my Viking dishwasher when I open it?
A small amount of water at the very bottom of the tub (less than an inch) is normal on many dishwasher models — it keeps the door gasket moist and the sump seal from drying out. However, if water covers the bottom of the tub (more than an inch), this indicates a drain failure and the filter should be cleaned immediately.
