Frigidaire dishwashers are typically regarded as reliable and efficient appliances, but, like any other electronic appliance, these machines may also face certain issues and error codes. Among the commonly occurring error codes, the most likely frustration would be dealing with error code 30.
This certainly brings lots of questions about what it means, what possible causes could be, and how it can be serviced.
Fortunately, we’ve compiled this extensive guide that should give you every detail you will ever likely need to know about the error code 30 on your Frigidaire dishwasher-from its possible causes and troubleshooting steps to some possible solutions.
What Does Error Code 30 on Frigidaire Dishwasher Signify?
Error code 30 would usually mean a problem with the heating of water. This indicates that the water is not reaching the temperature within a given time, which means that the dishwater does not function properly because hot water is the main energy source for melting grease and breaking food particles.
Common Reason Causing Error Code 30
The Frigidaire error code 30 can arise out of several factors. This means that one has at least a few things to consider while thinking through what could be wrong at a given moment.
Faulty Heating Element: The component responsible for warming the water is the heating element; whenever there is something faulty or burnouts with this equipment, it fails to heat the water properly. Thus, triggering the error code 30.
Faulty Temperature Sensor: The temperature sensor measures the temperature of the water and feeds back data to the control board, as it acts as a pathway for judging its effectiveness; therefore, if this sensor is faulty, it may record an incorrect temperature, causing error code 30 on the display of the dishwasher.
Control Board Issues: The travel brain within the dishwasher is responsible for conducting various functions, including the heating of the water. Under faulty operation, the control board fails to turn on the heating element, resultantly showing the error code 30.
Water Inlet Valve Problems: The water inlet is responsible for letting water in the dishwasher; thus, if a malfunction occurs in this, the flow into the dishwasher will be inadequate, failing to heat the water.
Wiring or Connection Problem: Loose or broken wire may disrupt communications among the components involved in heating the element, temperature sensor, and control board and hence result in error code 30.
Low Water Pressure: Not enough water pressure is also another reason why the appliance might show Error code 30, probably because of inadequate water input by the dishwasher that is generally needed to activate the heating element.
How to Fix Frigidaire Dishwasher Error Code 30
Before going to a professional technician, you can do these steps in troubleshooting with your Frigidaire dishwasher error code 30.
Check the Heating Element:
After unplugging the dishwasher. The heating element can be found on the bottom of the dishwasher.
Check for visible indicator damage, for example, the burns or even breakage.
Using a multimeter, check the continuity in the heating element. If there is no continuity, then the heating element is faulty and should be replaced.
Test the Temperature Sensor:
Identify the temperature sensor; it should be close to the heating element.
Remove the sensor and take resistance with multimeter; compare the reading within the specification of the manufacturer.
If the value is not within the recommended range, then this sensor can be faulty and should be replaced.
Control Board Inspection:
Examine the control board for visible signs of damage, such as burnt-out components or loose connections.
If you suspect that it is a faulty board, try resetting it by unplugging the dishwasher for a few minutes and plugging it back in.
When the problematic scenario persists, the control board is to be exchanged.
Check the Water Inlet Valve:
Find the water inlet valve; normally, it’s located at the back of the dishwasher.
Look at the valve for signs of damage or obstruction.
Using a multimeter test, ensure that the solenoid in the valve works properly. If it doesn’t, you need to change the water inlet valve.
Check Wiring and Connections:
Now check for all wire connections between the heating element, temperature sensor, and control board.
Also, check if there are any loose, damaged, or corroded wires and repair/replace as needed.
Verify Water Pressure:
Water to the dishwasher should be turned on and it should be clear of kinks or blockage in the water line.
Run a faucet close to the dishwasher and check if it is low on pressure. If the water pressure is lower than normal, you will have to get to fix the plumbing inside your house.

Regular Cleaning of the Dishwasher: The most apparent preventive maintenance action is keeping the dishwasher clean on a regular basis by removing food debris and residue from the filter, spray arms, and its interior.
Examine Parts and Replace When Required: Check from time to time the state of the heating element, temperature sensor, and others. Any part that appears to wear out or becomes damaged must be replaced.
Check the Water Pressure: It should be known that the home water pressure is always advised for dishwashers to operate properly. Thus, install a water pressure regulator.
Correct Detergent Usage: Use a good dishwasher detergent that matches the model of the dishwasher. Also avoid using more detergent than it is required because this leads to clogging and deprives the dishwasher its functioning.
Run the Maintenance Cycles: These run automatically on some dishwashers and include maintenance or cleaning cycles that remove buildups in this appliance and make it function ever smoothly. Refer to your dishwasher’s manual for instructions on running these cycles.
