Guidance for Frigidaire dishwashers. Check the feature and control descriptions against your model.
Frigidaire defines i40 as a clogged filter or sump condition caused by food soils. Clean the model’s glass trap/filter as directed and rerun the unit; if the indication returns, contact support rather than applying an unrelated code meaning.
Specifications & model details
Frigidaire FDSH4501AS5A is the exact code in this catalog record. This topic should be evaluated for that code and dishwashers category. The original source record is linked below; unrecorded settings, dates and compatibility remain unknown.
Work from visible water and drain-path clues to identify a blocked filter, air gap, disposer connection, or issue requiring service.
Category & symptom guidance
After a cycle, look at the lowest point of the tub. Some dishwashers retain a small amount of water below the filter to protect seals; a tub full of cloudy or dirty water is a different symptom. Note the level before starting another cycle and whether it rises, smells of sewage, or returns from the sink drain.
If the machine stopped mid-cycle, the water may simply remain because the drain phase did not run. Record the display, blinking light, and whether the cycle was interrupted. Avoid repeatedly restarting a full wash; it can add water without resolving a blocked discharge path.
Turn the dishwasher off at its controls and let hot water cool before touching the tub. Remove the lower rack only if it rolls freely. Lift or twist the filter according to its molded marks or exact-model directions; layouts vary and a fine filter may lock to a separate food basket.
Discard scraps into the trash, rinse the parts, and use a soft sponge to remove residue. Check the sump opening visually without reaching into hidden passages. Reinstall the assembly until it sits securely. A missing or tilted filter can let debris travel into the drain system, so do not run a cycle until it is correctly seated.
An air gap is a small plumbing fitting near the sink faucet or countertop, not a dishwasher part. If one is installed, inspect whether water or debris is visible beneath its cover. Clean it only as its design permits and replace the cap and cover afterward. Not every location or installation uses an air gap.
If water spills from the air gap during a drain, the downstream path may be obstructed. Do not push debris deeper with a sharp object or dismantle unfamiliar plumbing. A clear air gap does not prove the hose, disposer inlet, or household drain is clear.
Run the sink and observe whether it drains normally. If the dishwasher shares a drain with a disposer, clear the disposer according to its own instructions and remove visible food waste. A new disposer installation can leave a knockout plug in the dishwasher inlet; that installation issue requires the installer or a qualified repairer to verify, not an owner reaching into the connection.
If the sink backs up when the dishwasher drains, the restriction may be in shared household plumbing. If the sink works but the dishwasher still leaves a full tub, document that difference. Never loosen a drain hose under a built-in appliance to test for flow.
A drain hose’s high loop and air-gap arrangement depend on the installation instructions and local plumbing requirements. GE's GD*640–670 / PD*705–795 owner manual lists a missing high drain loop or air gap as a possible problem for its covered models, but do not copy that routing to another installation without its instructions.
After cleaning accessible debris and checking sink behavior, a persistent full tub, pump hum without discharge, or repeated return of dirty water calls for service diagnosis. Provide the amount of water, whether the sink drains, any unusual sound, and the point in the cycle when draining should occur. Keep the dishwasher unused if water is leaking onto the floor.
This may be normal retained water for the design.
Not unless the owner instructions say it is abnormal; a small amount may be retained by design.
No. Hose access and routing are installation work; use a qualified repair path.
