Electrolux Dishwasher Error Code i93

The i93 code indicates a UIDATA checksum error on the user interface board. The board runs a verification routine on its stored configuration data, and i93 appears when that verification returns an invalid result. As a result, all electronic functions on the dishwasher are blocked until the fault is resolved. The fix may be as simple as a power cycle, or it may require UI board replacement.

Start with a full power cycle by disconnecting the appliance from power for at least five minutes. If the error persists, inspect the wiring harness connections at the UI board for loose terminals, corrosion, or visible damage and reseat any suspect connectors. If the error continues after addressing the connections, the UI board itself is likely faulty and will need to be replaced.

If the error clears with a power cycle, there is no parts cost involved. If the UI board requires replacement, parts typically range from around $80 to $200 or more depending on the specific model. Adding professional labor, total repair costs commonly fall between $150 and $350. Getting a diagnosis from a qualified technician first can help determine whether a board replacement is actually necessary before spending on parts.

A power cycle is the first recommended step and can clear i93 if the cause was a transient memory glitch. Unplug the dishwasher or turn off the circuit breaker for several minutes, then restore power and observe whether the error returns. If i93 comes back after the reset, the underlying fault is likely a hardware issue with the UI board or its connections that requires further diagnosis.

The dishwasher blocks all electronic functions when i93 is active, so the appliance will not operate in this state. There is no immediate safety hazard, but you cannot run any wash cycles until the error is cleared. Do not attempt to bypass the lockout. Address the root cause through proper diagnosis before using the appliance again.
