Frigidaire Dishwasher Not Draining: Causes & Fixes
Standing water at the bottom of a Frigidaire dishwasher after a cycle almost always traces back to one of a few common blockages or a failed drain pump.
Common causes
Clogged filter or sump
Food debris collects in the filter basket at the bottom of the tub. A clogged filter is the single most common cause of drainage problems.
Kinked or clogged drain hose
The hose running from the dishwasher to the garbage disposal or drain line can kink behind the unit or clog with debris.
Garbage disposal knockout plug
If your dishwasher was recently connected to a new garbage disposal, the knockout plug inside the disposal inlet may not have been removed, blocking drainage entirely.
Failed drain pump
If the pump motor itself fails, water won't drain no matter how clear the rest of the system is.
Clogged air gap
If your sink has an air gap fitting, debris can clog it and prevent the dishwasher from draining properly.
What to check first
Remove and clean the filter
Most Frigidaire models have a removable cylindrical filter at the bottom of the tub — twist and lift it out, then rinse away trapped food debris.
Check the air gap (if you have one)
Remove the chrome cap near your faucet and clear any visible debris.
Inspect the drain hose
Check behind the dishwasher and under the sink for a kinked or pinched hose.
Run the disposal
If connected to a garbage disposal, run it empty for a few seconds to clear anything blocking the shared drain line.
Run a short cycle
After clearing the filter and hose, run a rinse cycle to see if water drains properly.
When to call a technician
If the filter, hose, and air gap are all clear and water still isn't draining, the drain pump itself has likely failed and needs replacement — this requires disassembling the base of the unit.
Frequently asked questions
Why does my Frigidaire dishwasher smell bad and not drain?
Standing water combined with trapped food debris in the filter is the usual cause. Clean the filter first — if the smell and drainage issue persist, the drain pump may need service.
How much does dishwasher drain pump repair cost?
Drain pump replacement typically runs $150 to $300 including parts and labor, depending on the model.
