Electrolux Dishwasher IC3 Error: UI memory / config fault
Electrolux dishwasher ic3 error — understanding this error code helps you decide on the right course of action for your Electrolux appliance. What Does Error Code iC3 Mean on an Electrolux Dishwasher? Error code iC3 on Electrolux dishwashers signals a memory or configuration fault on the user interface board. The EEPROM chip on the UI […]

Answer to continue safely
Is it safe to keep using?
No. With corrupted configuration data, the dishwasher may not operate its cycles correctly even if it appears to start. Incorrect cycle parameters could result in improper water temperatures, fill levels, or cycle durations.
Can I reset the code?
Yes. An extended power disconnection (10+ minutes) may allow the board to reinitialize from backup data. If the EEPROM chip itself is damaged, no amount of power cycling will resolve the fault.
When to stop immediately?
Stop if you notice: The display shows garbled characters or incorrect model information after a 10-minute power cycle, The error returns immediately on every power-up.
Symptoms You May Notice
Incorrect cycle options shown on the display
The control panel shows cycle names, times, or options that do not match your model, because the UI board is reading corrupted configuration data from its memory.
Dishwasher will not start any cycle
The control board refuses to begin a cycle because it cannot validate the configuration data received from the UI board, displaying iC3 instead.
Display language resets or changes randomly
If the EEPROM data is partially corrupt, user preferences like display language may revert to factory defaults or switch to an unexpected language.
iC3 appears after a power outage
The error first surfaces after an abrupt power loss or electrical storm, which likely caused the EEPROM write corruption during an interrupted save operation.
Possible Causes
EEPROM data corruption
A power surge, brownout, or interrupted firmware update has corrupted the stored configuration data on the UI board EEPROM chip, making it unreadable or inconsistent.
Requires ProfessionalFailed EEPROM IC
The memory chip itself has reached end-of-life or suffered a physical failure, permanently losing or scrambling the stored configuration data.
Requires ProfessionalUI board hardware failure
A component failure on the UI board — such as a power regulator that feeds the EEPROM — prevents proper read/write operations to the memory.
Requires ProfessionalSafe Checks You Can Do
-
1
Extended power disconnection
Turn off the circuit breaker for the dishwasher and leave it off for at least 10 minutes. This allows all board capacitors to fully discharge and may enable a clean EEPROM re-read when power is restored.
10 minutes is the minimum — 30 minutes is even better for a full capacitor drain on these boards.

Restore power and observe startup
Turn the breaker back on and watch the display carefully during the power-on sequence. All display segments should light up briefly, then show the default cycle. If it shows normal options, try running a cycle.
If the display shows garbled characters during startup, the EEPROM is likely corrupted beyond a simple reset.

Note any patterns
Record exactly what the display shows and which buttons work. Take a photo if possible. This information helps a technician determine whether the EEPROM can be reprogrammed or if the board needs full replacement.
If the display alternates between normal and garbled — the EEPROM has intermittent read failures.
When to Call a Professional
Contact a qualified technician if:
- A known power surge or lightning event preceded the first appearance of iC3
- The board shows visible damage to the EEPROM IC area — discoloration, swelling, or cracked solder joints
- The same UI board fails on a test machine, confirming the board itself is the issue
