What the E:02 error code actually means

Your Frigidaire dishwasher is showing E:02 because the part that controls the heating function has a faulty switch inside it. This means your dishwasher may not be heating water properly or completing its drying cycle. The main circuit board in the bottom of the machine needs to be replaced to fix this issue.

Questions people ask about E:02

What does E:02 mean on a Frigidaire dishwasher?
E:02 indicates a faulty heater relay on the power module, which is the main control and power board located in the base of the dishwasher. The heater relay is responsible for switching electrical current to the heating element during wash and dry cycles. When this relay fails, the dishwasher detects the fault and displays E:02. Resolving this error requires replacing the power module.
Will resetting my Frigidaire dishwasher clear the E:02 error?
A simple reset is unlikely to permanently clear E:02 because the code reflects an actual hardware fault with the heater relay on the power module board. The error may temporarily disappear after a reset but will return once the dishwasher attempts to activate the heater circuit again. The underlying component failure must be addressed by replacing the power module.
How much does it cost to fix the E:02 error on a Frigidaire dishwasher?
The cost to repair E:02 depends on whether you hire a technician or do the repair yourself. A replacement power module part typically costs in the range of $80 to $200 depending on the specific model. If you hire a professional, labor costs can add another $100 to $200 on top of the part, bringing the total repair estimate to roughly $180 to $400.
Can I fix the E:02 error on my Frigidaire dishwasher myself?
A knowledgeable DIYer can replace the power module in the base of the dishwasher, but the repair does involve working with high-voltage components. You should disconnect power to the appliance at the breaker before beginning any work. If you are not comfortable working around electrical components, a qualified technician should perform the replacement.
Is it safe to use my Frigidaire dishwasher when E:02 is displayed?
You should not continue using the dishwasher while E:02 is active. A faulty heater relay can mean the heater is not being controlled properly, which poses a risk of the heater circuit behaving unpredictably. Discontinue use until the power module has been inspected and replaced.
