4. Filter or sump clogged with food

How to fix the C1 code

1. 1

   Step 1: Run the garbage disposal

   If the dishwasher drains into a disposal, run it with cold water for 30 seconds to clear it.

2. 2

   Step 2: Clean the air gap

   If you have a small chrome cap next to the faucet, pull off the cap and cover and clear any debris inside.

3. 3

   Step 3: Check the drain hose

   Look under the sink for kinks or low sags in the drain hose. It should loop up high before it connects.

4. 4

   Step 4: Clean the filter

   Remove the bottom rack, twist out the filter in the floor of the tub and rinse it under warm water.

You'll need: Flashlight, soft brush, towels.
