What the i94 error code actually means

Your Electrolux dishwasher is showing this error because the control panel board and the main computer inside the appliance are not speaking the same language due to a version mismatch. This usually happens after a repair or update where a mismatched or incorrectly programmed control panel was installed. The dishwasher cannot fix this on its own and will need a technician to inspect or replace the control panel board.

Questions people ask about i94

What does i94 mean on a Electrolux dishwasher?
The i94 code means there is a UIDATA version mismatch between the configuration file on the main control board and the user interface board installed in the dishwasher. The two components are not running compatible data versions, so the system cannot complete a UI configuration update. This error requires inspection of the UI board to confirm it is the correct part, followed by reprogramming or replacement.
How do I fix the i94 error on my Electrolux dishwasher?
Start by confirming that the UI board installed in the dishwasher is the correct part for your specific model. If the board is correct, a technician may be able to reprogram it to align its UIDATA version with the main control board's configuration file. If reprogramming is not successful or not available, replacing the UI board with a confirmed compatible unit is the recommended fix.
How much does it cost to repair the i94 error on an Electrolux dishwasher?
Repair costs depend on whether the fix requires only reprogramming or a full UI board replacement. If reprogramming resolves the issue, you may only incur a diagnostic and labor fee, typically in the range of $75 to $150. If a new UI board is needed, total costs including parts and labor generally range from $150 to $350, depending on the specific model and local service rates.
Will resetting my Electrolux dishwasher clear the i94 error?
A simple reset will not clear the i94 error because the underlying cause is a hardware or firmware version mismatch, not a temporary software glitch. Every time the dishwasher powers on, it checks the UIDATA versions and will re-trigger the error if they still do not match. Resolving the mismatch through reprogramming or board replacement is necessary to permanently clear the code.
Is it safe to use my Electrolux dishwasher while the i94 error is showing?
The i94 error typically prevents the dishwasher from operating normally, as the system cannot establish proper communication between the UI board and the main control board. Attempting to force operation in this state is not recommended, as the UI controls may not function reliably. The appliance should be serviced before returning it to regular use.
