Frigidaire Dishwasher Error Code iC2

The iC2 code indicates an ADSI communication failure between the user interface board and the main hardware control board. The dishwasher attempted to establish this internal communication link three times and failed each time. This error is signalled by the hardware control to indicate that the two boards cannot exchange data. The fault is usually related to wiring, connectors, or one of the two control boards.

A power reset, performed by unplugging the dishwasher or switching off its circuit breaker for a few minutes, may temporarily clear the iC2 code. However, if the underlying communication fault is caused by a wiring issue or a failed control board, the error will return. A reset is a reasonable first step but should not be considered a fix if the code reappears.

If the fix is as simple as reseating a loose connector, there may be no parts cost at all, only a service call fee if a technician is involved, typically in the range of $75 to $150. If a wire harness needs replacement, parts and labor combined often fall in the $100 to $200 range. Replacing a UI board or main control board is more expensive, with total repair costs commonly ranging from $150 to $350 depending on the specific board and labor rates in your area.

Some cases of the iC2 error can be resolved without professional help by inspecting and reseating the wire harness connectors between the UI board and the main control board. If the connectors are secure and the harness shows no visible damage, the repair will likely require replacing a control board, which is a more involved task. Technicians comfortable working with appliance electronics can often handle this repair, but others may prefer to call a qualified service technician.

When the iC2 error is active, the dishwasher's two control boards cannot communicate reliably, which means the appliance may not operate correctly or may not run at all. It is best to avoid attempting to run a wash cycle until the fault is diagnosed and resolved. Continuing to operate the unit in this state could prevent proper cycle control and may mask other developing issues.
