Answer to continue safely
Is it safe to keep using?
No. The dishwasher cannot operate without communication between its control boards. Attempting to force a cycle with an intermittent connection could result in unpredictable behavior such as running indefinitely or not responding to the cancel command.
Can I reset the code?
Yes. A full 5-minute power cycle may resolve a transient communication glitch. If the connector or board is physically damaged, the code will return as soon as the boards attempt to communicate.
When to stop immediately?
Stop if you notice: The display remains blank or shows garbled data after a 5-minute power cycle, You see visible moisture, rust, or corrosion inside the door panel.
Symptoms You May Notice
Display shows iC0 and buttons are unresponsive
The error code appears on the display but pressing any buttons produces no response because the user interface board cannot communicate commands to the main control.
Dishwasher appears completely dead
In some cases, the communication fault prevents the display from lighting up at all, making the machine appear to have no power even though the breaker is on.
Random cycle interruptions
Before a full communication failure, intermittent connection issues may cause the dishwasher to stop mid-cycle unpredictably as communication drops in and out.
Display flickers or shows garbled characters
A partially degraded communication link may produce flickering segment displays, random characters, or incorrect cycle information.
Possible Causes
Loose ribbon cable connector
The flat cable connecting the UI board in the door panel to the main control board has worked loose from its socket due to door vibration over thousands of cycles.
Requires ProfessionalCorroded connector pins
Steam and moisture have entered the door panel through gaps or worn seals, causing oxidation on the connector pins that interrupts the data signal.
Requires ProfessionalFailed control board
A component failure on either the main PCB or the UI board — typically a capacitor or communication IC — prevents data exchange even with good connections.
Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the dishwasher
Turn off the circuit breaker for the dishwasher and leave it off for a full 5 minutes. This allows all capacitors to discharge and resets both control boards. Restore power and check if the display initializes normally.
A simple 30-second reset is often not enough for communication faults — give it the full 5 minutes.

2
Check for visible damage on the door panel
Inspect the inner door panel for signs of moisture, rust stains, or swelling that would indicate water intrusion near the electronic boards. Look at the bottom edge of the door where condensation tends to collect.
If you see rust stains below the control panel, moisture has likely reached the connectors.

3
Verify power supply
Confirm the outlet or breaker provides consistent voltage by plugging in another appliance. Fluctuating power supply can cause intermittent communication faults between the boards.
If you experience frequent power outages or brown-outs, a surge protector may help prevent recurrence.
When to Call a Professional
Contact a qualified technician if:
- Power cycling does not resolve the fault and iC0 appears immediately every time
- Visible corrosion on the ribbon cable connector or board pins
- The UI board has swollen or leaking capacitors visible on the circuit board
