Frigidaire Dishwasher Error Code i20
A Frigidaire dishwasher displaying i20 is indicating a drainage problem. The dishwasher did not drain completely, which usually means there is a restriction somewhere in the drain system. In many cases, the problem can be related to the drain hose, filter, sump, or garbage disposal connection.
The dishwasher detected that water did not drain properly. Check the drain path, hose, filter, sump, and garbage disposal connection before scheduling service.
What Does Frigidaire Error Code i20 Mean?
Frigidaire error code i20 means the dishwasher did not drain completely. The control system detects that water remains in the dishwasher when it should have been pumped out.
The code does not necessarily mean that the drain pump has failed. A clogged filter, blocked drain hose, improper hose installation, or a blocked garbage disposal connection can also cause the same symptom.
Frigidaire specifically recommends checking the drain hose, the dishwasher filters and sump, and the knockout plug in the garbage disposal when applicable.
Common Causes of Frigidaire i20
Clogged Filter
Food particles and debris can restrict water flow through the dishwasher filter and prevent the unit from draining correctly.
Blocked or Kinked Drain Hose
A restricted or sharply bent drain hose can prevent wastewater from leaving the dishwasher.
Blocked Sump
Food debris can collect in the sump area and interfere with normal drainage.
Garbage Disposal Connection
If the dishwasher is connected to a garbage disposal, an improperly prepared connection or an uncleared knockout plug can prevent drainage.
What to Check When Your Frigidaire Dishwasher Shows i20
Before calling for appliance repair, there are several basic drainage checks you can safely perform.
How to Reset Frigidaire Error Code i20
After correcting an obvious drainage restriction, you can try resetting the dishwasher.
- Press and hold the Cancel button.
- If necessary, turn the dishwasher power off at the circuit breaker.
- Alternatively, unplug the dishwasher for approximately 3 minutes.
- Restore power and run a short cycle to see whether the dishwasher drains normally.
If the dishwasher continues to display i20 after the basic drainage checks and reset, the underlying problem may require further diagnosis. Continuing to reset the appliance will not fix a mechanical or electrical component that is causing the drainage failure.
When Should You Call a Frigidaire Dishwasher Repair Technician?
Professional diagnosis is recommended when the dishwasher still will not drain after checking the filter and drain hose, or when the i20 code repeatedly returns.
A technician can determine whether the problem is related to the drain pump, wiring, control system, a deeper blockage, or another component in the dishwasher’s drainage system.
If there is standing water in the dishwasher and you cannot determine why it is not draining, avoid repeatedly running full cycles until the problem is diagnosed.

What does i20 mean on a Frigidaire dishwasher?
i20 means the dishwasher did not drain completely. The first things to check are the filter, sump, drain hose, and garbage disposal connection if applicable.

It is better to resolve the drainage problem before continuing to use the dishwasher normally, especially if water remains inside the tub after a cycle.
