F9E1 — Long drain
Long drain — the dishwasher isn't draining, or is draining too slowly.
Common causes
- Filter clogged with food and hard-water scale
- Kinked drain hose
- Disposal clogged or knockout plug not removed
- Blocked air gap
- Failed drain pump
Try this first
- Twist out and rinse the filter
- Check the drain hose under the sink
- Run the disposal and clear the air gap if you have one
When to call: A humming dishwasher that won't drain with a clean filter usually needs a drain pump.
