What i40 means
On Frigidaire dishwashers with a digital status window from the i-code generation, roughly 2010 and later, i40 means a clogged filter or sump. Food soil has built up where the dishwasher collects water, which restricts circulation and drainage. The code often appears after heavy use with unrinsed dishes, and cleaning usually clears it. Rinsing dishes lightly and cleaning the filter regularly keeps it from coming back.
Common causes of i40
- Food soil built up in the glass trap and filter
- A sump restricted by debris
- The circulation or drain pump if cleaning does not help
1. Open the door and remove the lower rack. 2. Take out the glass trap and filter and clean away food soil. 3. Put the filter and trap back and re-run the dishwasher. 4. If i40 continues, call us. 5. Rinse the removed filter under running water until the mesh is clear.
- If the filter and sump are clean and i40 returns, we test the circulation and drain pump.
- We also check for debris past the filter that owners cannot reach.
- Written pricing comes first.

What does i40 mean?
i40 means the filter or sump is clogged with food soil. Water cannot move through the dishwasher freely until it is cleaned. Rinsing dishes lightly helps.
How often should I clean the filter?
It depends on use. If you do not rinse dishes much, check it every month or so. A quick rinse under the tap is usually enough.
The filter is clean and i40 stays. What next?
Debris may be deeper in the sump, or the pump may be restricted. We inspect the whole path at your home and give you the price in writing before any work.
