What Does Error Code iC0 Mean on a Frigidaire Dishwasher?

Communication error — touchpad/control not talking to main board.

The main control board flags iC0 when it stops receiving valid data from the user-interface (touchpad) board across the inter-board ribbon or harness. Without both boards exchanging status, the control can't safely sequence a cycle, so it halts. Unlike a PF power-failure code, which reflects an interrupted supply, iC0 points specifically to an internal data-link problem — most often a loose or corroded connector, and less commonly an outright failure of either board.

Models affected: Frigidaire dishwashers with a separate touchpad/user-interface board and main control board, including models such as FFCD2418US, FGID2466QF, and FFBD2412SS
What owners report: Owners commonly report iC0 appearing at power-up or mid-cycle, sometimes after moisture reaches the door-panel connectors. Many say a simple power cycle or firmly reseating the ribbon harness clears it, so that quick win is worth trying before suspecting a failed board.

Frequently Asked Questions

Can I keep using my Frigidaire Dishwasher when error iC0 appears? +
You often can for a cycle or two, but the communication issue behind iC0 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes iC0 on a Frigidaire Dishwasher? +
Across reported Frigidaire dishwasher repairs, the most frequent is loose or unseated ribbon/harness between UI and main board (45% of cases), user-interface (touchpad) board failure (25%), then main control board failure (20%). Check them in that order before replacing any parts.
iC0 keeps coming back after a reset — what should I check next? +
A reset only clears the stored iC0 fault; if it returns, the communication problem is still present. Move on to the physical checks — power cycle, then reseat the inter-board harness — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Frigidaire Dishwasher error iC0? +
A DIY repair typically runs $0–$230 in parts, versus $140–$330 for a professional service call, so handling it yourself saves around $140. Expect the work to take roughly 30–60 minutes.
Which Frigidaire Dishwasher models show error iC0? +
iC0 is documented on Frigidaire dishwashers with a separate touchpad/user-interface board and main control board, including models such as FFCD2418US, FGID2466QF, and FFBD2412SS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
