Frigidaire Dishwasher Error Code i30

Frigidaire dishwasher is a common kitchen appliance in most American homes because of its advanced features. The dishwasher has a self-diagnosis mechanism that generates codes that inform a user about interruptions and issues in the operation of its subunits and sensors. Each of these codes is unique and corresponds to a specific problem within the washer.

One of the most common codes in the Frigidaire dishwasher is the error code i30. This code means the dishwasher is consuming a lot of water. When error code i30 appears on your dishwasher’s digital display, your appliance will begin draining water non-stop. In this situation, the dishwasher’s pump operates without stopping. It also does not respond to opening doors and commands to cancel the program.

What does Error Code i30 Mean?

Important: As a homeowner, realizing that you need to waste another Saturday waiting for the landlord or handyman to come over to fix another damaged appliance is frustrating. It shouldn't feel like the norm to constantly have damaged appliances and systems in your home since it can come to a huge cost at the end of each year.

The Home Improvement Solutions eBook covers everything you need to do in your home when it comes to maintenance and improvement so you can avoid wasting another weekend waiting for someone to come to your rescue.  
When your dishwasher’s tank fills up, fluid flows into the bottom of its pan. The dishwasher’s float switch actuates, causing an interruption in its cycle and appearance of the error code i30 on its digital display screen. When this happens to your Frigidaire dishwasher, you can try to fix it by unplugging the washer from its power source for 30 minutes then restart it. Check its display screen for changes. If nothing has changed on the dishwasher’s display screen, you need to carry out these actions to correct the issues.

  1. Pull out the dishwasher from under the tabletop
  2. Tilt its housing forward by about forty-five degrees to drain water from the dishwasher’s pan
  3. Position the appliance in an upright position and return it in its normal position
  4. Wait for forty-eight hours for its pan to dry completely
  5. Carry out a test run on the appliance after two days to see if it is running normally and the error code i30 has disappeared

While these steps will remove error code i30 from your dishwasher’s digital display screen, it does not work for a long time. The error code will reappear after a while. Dishwashers without a digital display screen, the ‘END’ LED flashes at 5-second intervals with each flash consisting of three blinks.

Causes of Fault Code i30

This error code could be caused by a number of faults within your dishwasher. Therefore, you will have to inspect the whole appliance to find the exact reasons for the fault and fix it to restore your dishwasher to its optimum efficiency. Here are some of the issues that you should be watching out for in your inspection.


It would be best if you began by inspecting the dishwasher’s pan. If the pan is empty, you should proceed to the next step. However, if the pan is wet, you should try to find the source of the leak. Follow these steps to fix the leak.

  • Unscrew your dishwasher’s top cover
  • Remove its sidewalls
  • Run any program
  • Observe the washer for possible leaking areas

Once you locate the leaking area, you need to cover it with a sealant. However, such a repair is short-lived and will soon give way to more leaks. To be safe, you need to replace the leaking element in its entirety. After carry out the repairs or replacement, run your washer and check its digital display screen. The i30 error code should have disappeared.

Dirty Leak Sensor

Frigidaire dishwasher has a plastic foam float at the bottom of its housing. The foam float activates the appliance’s switch when its pan is full. However, in some cases, a moving part of the foam float sticks on the wall sending the wrong message to the appliance, making it think that there is an overflow in the dishwasher. In this circumstance, it is easier for the user to get rid of the error code by cleaning the dirty leak sensor.

Blocked Drain System

At times, error code i30 combines with error codes i40, iF0, or i20 to indicate a drain problem in the appliance. When this happens, you need to begin by inspecting the dishwasher’s sewage system and the area below the sink where a connection between the dishwasher and your home’s piping has been made. You need to open it up and remove the filters for cleaning. Inspect the hoses for folding and blockage while at it.

Faults with the Drain Pump

A dishwasher may overfill because of a malfunctioning pump. In most cases, fault code i30 occurs when the appliance’s impeller is broken or blocked. When this happens, you need to disconnect the dishwasher’s pump and remove everything blocking the blades. If the pump’s impeller is broken, you need to replace it with a new one. If there is no visible damage to the pump, you need to examine the subunit using a multimeter. If the subunit does not have continuity, you need to purchase a new drain pump.

Damaged Inlet Valve

On a normal occasion, this component opens and closes to control the flow of water in the dishwasher. However, it can also breakdown. When this happens, this part could cause the dishwasher to show error code i30 on its digital display code. Some of the common causes of this issue include:

  • Faulty wiring
  • Mechanical issues in the dishwasher
  • Blockage

You need to follow specific steps to fix this issue. Follow this procedure to fix the problem:

  1. Remove and disassemble your dishwasher’s electromagnetic part
  2. Inspect it for garbage. If you find any, you need to get rid of it
  3. Use a multimeter to measure the contact resistance of the inlet valve
  4. If there is no continuity, you need to replace the valve with a properly functioning unit

Faulty Pressure Switch

Sometimes the pressure switch (view on Amazon) becomes clogged with fat or food and sends the wrong signals to the dishwasher’s control board, making it think the tank is empty. Therefore, the system does not create a command for its intake valve, preventing the membrane from closing. Water continues to flow into the dishwasher. It spills and enters its pan. The leakage sensor picks up the problem and responds to it by sending a signal to the main control, which displays the i30 error code. You need to clean the pressure switch to correct this problem. However, if the sensor has broken down, you need to replace it to fix the issue.

Faulty Electronic Board

The Frigidaire dishwasher shows error code i30 on its digital display screen when moisture gets into its main module, causing a drop in voltage or when there is a short circuit in the dishwasher. In most cases, this occurs when there is a burnt-out triac that controls the filling and discharge. When this happens, you need to replace the old element by installing a new and proper functioning element. It would be best if you also soldered the molten tracks where necessary. However, you should note that if the processor has burned out, soldering will not help. Instead, you will have to buy a new component to replace the old burned part.
