> AGA dishwasher not draining / water left in the tub: symptoms, likely causes and how a technician diagnoses it. Very common AGA issue. Mon–Sun 8:00AM–8:00PM. Call or text 206-427-7323.

Very common issue — here is how we diagnose it, which parts are usually involved, and when to call a pro.

**Very common** · Starts with cleaning

## What you will notice

- Standing water at the end of a cycle

## What is usually behind it

- Filters clogged (most common)
- Drain hose kinked or air gap blocked (very common)
- Drain pump blocked by debris or glass (common)
- Drain pump failed (common)
- Garbage disposal knockout plug not removed at installation (common on new installs)

## How a technician diagnoses it

1. Clean the filters — the owner's guide has a dedicated 'Cleaning the Filters' procedure and this is the first check.
2. Cancel-cycle behaviour for reference: press and hold Program Selection/Cancel for 3 seconds, 3-2-1 counts down, 0:01 displays, close the door and draining completes in about 2 minutes with a beep.
3. Check the drain hose routing, high loop and air gap.
4. Inspect and clear the drain pump.
5. This is a Middleby Residential / Viking platform — use Viking-platform service data for pump testing and fault codes.
