What iC0 means on your Frigidaire dishwasher (frigidaire ic0 error)
A frigidaire ic0 error means the control panels or boards have lost communication on your Frigidaire dishwasher. The user-interface board and the main control are not exchanging data, so the panel may go unresponsive. It is most often a connection or board fault.
Symptoms
The indicators below help confirm the condition on your Frigidaire dishwasher rather than a different issue that mimics it closely. Your dishwasher might produce one symptom or a handful together, whether they develop slowly or land all at once after a power event, a demanding wash or cook cycle, or recent installation.
- An unresponsive control panel
- Buttons that do nothing when pressed
- The cycle will not start
- The display freezes or blanks
Common causes
It takes only one of the faults below to make a Frigidaire dishwasher act like this, but they are listed likeliest-first for good reason. Following that order distinguishes a fast owner check on the dishwasher from a fault that needs trained service and correct Frigidaire parts.
- Loose ribbon or harness — the link between boards backed out
- Failed user-interface board — the panel board cannot communicate
- Failed main control board — the main board lost the data link
- Moisture at a connector — water bridged the board pins
Troubleshooting steps you can try
The steps below are ordered so the quickest and safest checks on your Frigidaire dishwasher come first. Stop wherever you are not confident, or where mains voltage, gas, a hot cavity, water, or a sealed component on the dishwasher is in play, and pass the job to a qualified technician.
- Power off at the breaker for five minutes to force a full reset.
- Confirm the door closes and latches so the panel powers up.
- Avoid pressing buttons repeatedly, which does not clear a comms fault.
- If iC0 returns, the boards and ribbon connection need service.
Parts a technician may replace
Depending on where the fault is traced, work on your Frigidaire dishwasher may involve inspecting, testing, or replacing the ribbon cable, wiring harness, user-interface board, and main control board.

Confirming the failed part before it is ordered keeps the repair on your dishwasher to the fault at hand.
