Frigidaire dishwasher repair from the i-code up

When a Frigidaire dishwasher shows i30, a sensor has found water in the pan underneath the tub. Frigidaire's first suspects are a loose connection at the inlet valve and a machine that is not sitting level.

Does soft Oahu water change how a Frigidaire is dosed?

Yes, it usually means less detergent. A USGS survey found Hawaii public water generally below 120 mg/L hardness, soft to moderately hard, though those figures are decades old. Frigidaire's chart starts soft water at about 2 teaspoons for Heavy or Normal and warns that overdosing soft water etches glass with a film that never wipes off. Cloudy glasses here are often too much soap, not a failing pump. Water temperature matters too: Frigidaire wants 120°F at the door, and colder supply simply makes the cycle run longer.

Frigidaire dishwasher faults, and what they usually are

Frigidaire models without a display talk through their status lights instead of codes. These are the patterns worth knowing before you call.

Two lights flashing

Hi-Temp Wash and Heat Dry blinking together mean the power dropped. START/CANCEL clears it.

Drains, lights blink

A drain followed by flashing status lights can mean a shorted keypad. Five minutes unpowered may clear it.

Will not fill

The overfill float in the left front corner should rise and fall about an inch. Stuck means no water.

Dishes come out wet

With no dry option picked, the heater stays off for drying. Choose Heat Dry and keep rinse aid topped up.

Leak at the door

Frigidaire checks that the gasket sits in its channel, reaches the tub bottom and the unit is level.

Pink or orange tub

Tomato-heavy loads tint the liner. Frigidaire says it fades and does not hurt performance.

Frigidaire codes and cycles

On the 2022 guide, yes. The stainless tub and inner door liner carry a lifetime limited warranty if they fail to hold water from a defect. Racks and the electronic control module get replacement parts in years 2 through 5, but labor in those years is yours. Rust is excluded throughout, which matters near the ocean.
It is heating the incoming water, roughly 1 to 2 minutes per degree, so a cold supply means a longer wait.
Yes. On the 2022 model Heavy Wash runs 2.5 to 3.75 hours before drying. DishSense checks how dirty the load is and adds or skips fills, and a temperature sensor stretches the cycle when the water comes in cool. Running the kitchen hot tap first shortens it.
Hold START/CANCEL for 3 seconds and it runs a 90 second drain.
No. Opening the door pauses it. Press START/CANCEL and shut the door within 10 minutes and it picks up where it stopped; wait longer and the cycle is cancelled.

Care, coverage and costs to run

The cycle did not meet its target. Sanitize lifts the final rinse to 155°F and holds it 9 minutes, and Frigidaire says a power cut, an interrupted cycle or incoming water below 120°F can stop it from qualifying. Check the water at your nearest hot tap with a kitchen thermometer.
Run a hot tap for several minutes first. Frigidaire warns that a hot water system unused for 2 weeks or more can build up hydrogen gas, which is flammable, so no smoking or open flame while it clears. Then run a cycle and check under the sink for drips.
Frigidaire suggests one ReadyClean tablet in the bottom of the empty tub, not the dispenser, a rinse cycle, and the door kept shut at least 6 hours. For hard-water film, pour 2 cups of white vinegar into the bottom at the second fill of a Normal cycle, with no detergent.

It helps. Most ENERGY STAR Frigidaire models are listed at 240 kWh a year against a federal limit of 307, and 3.20 gallons a cycle against 5. With Hawaii residential power at 48.00 cents per kWh in July 2026, the gap adds up over a dishwasher's life, though repair is often still the cheaper path; see our repair or replace guide.
