Frigidaire Dishwasher Not Draining: Step-by-Step Checks

Quick answer: Start with the filter/sump, drain hose and disposer connection. A Frigidaire dishwasher can show an i20-type drain issue when water does not leave the tub as expected.

When troubleshooting, keep the full Frigidaire model number and any displayed code. A symptom describes what the appliance is doing; it does not prove which part failed.

Most Likely Causes

Clogged filter or sump

Food debris can restrict water entering the drain pump. ### Kinked or obstructed drain hose

A crushed hose or internal blockage slows or stops discharge. ### Garbage-disposer knockout plug still installed

A newly connected dishwasher cannot drain into a disposer if the inlet plug was never removed. ### Incorrect drain-hose installation

Improper height or routing can cause poor draining or backflow. ### Drain pump issue

A jammed or failed pump may hum, stop or fail to move water. ### Water-level/control problem

The control may misread residual water or fail to operate the pump correctly.

What to Check First

1. Cancel the cycle and allow the dishwasher to perform its normal drain routine.
2. Clean the user-accessible filter and sump area according to the owner guide.
3. Inspect the visible drain hose for kinks or crushing.
4. If connected to a garbage disposer, verify the dishwasher inlet was opened during installation.
5. Check that the household sink/disposer drains normally.
6. Record i20, i40 or any other displayed code before resetting power.

These checks are intended to separate common external conditions from issues that require internal testing. Do not bypass safety devices or perform live electrical tests just to “see whether a part works.”

How Error Codes Change the Diagnosis

A displayed code can narrow the problem, but Frigidaire/Electrolux has used multiple electronic-control platforms. The same characters are not always universal across every model.

Use the matching directory:

Frigidaire Dishwasher Error Codes

If the code page includes a model/platform warning, treat that note as part of the diagnosis.

When Professional Repair Is Needed

Schedule service if the pump does not run, the hose is clear but water remains, a leak is present in the base, or a drain/pressure/control code returns after the external drain path is verified.

Also stop using the appliance for smoke, burning odor, sparking, repeated breaker trips, gas odor, uncontrolled heating, water reaching electrical components or another unsafe condition.

Repair vs. Replace

Do not make a replacement decision from the symptom alone. First identify the failed system. A hose, switch, sensor, fan, valve or wiring repair has a very different cost and risk profile from a main control, sealed refrigeration system, motor drive or high-voltage microwave failure.

Useful factors include:

• confirmed failed system;
• correct part availability for the exact model;
• overall condition of the appliance;
• whether more than one major system has failed;
• installation cost and requirements for a replacement.

FAQ

Can I reset this Frigidaire dishwasher problem?

A short power reset can clear a temporary electronic state on many appliances, but a reset does not correct a mechanical, electrical, airflow, water, gas or sealed-system issue. If the symptom returns, diagnose the cause.

Should I replace a part based only on this symptom?

No. The same symptom can be produced by several components or by installation/supply conditions. Use the model number, operating sequence and any error code before ordering parts.

Where can I find the Frigidaire model number?

Use the product rating label and keep the full model string, including suffixes. Model location varies by appliance family. The exact model is important because control platforms and parts can differ.

What if the appliance shows an error code too?

Write the code down before resetting the appliance and use the appliance-specific code directory: /frigidaire-dishwasher-error-codes/. The code definition should be matched to the correct appliance/model platform.

Official manuals and support notes are available on Frigidaire owner support.

Remember: Frigidaire Dishwasher Not Draining: is easier to resolve when you capture the model number and when Frigidaire Dishwasher Not Draining: first appeared.

Write down the full model number before ordering parts. Board and sensor revisions can change which part number is correct.

A single power reset can clear a temporary fault, but repeated returns of the same code usually mean a physical cause remains.

Keep vents and filters clear between visits. Restricted airflow often mimics electrical or sensor failures.

If water, burning smells, or sparking are present, stop using the appliance and arrange a professional inspection.
