Electrolux Dishwasher IC1 Error: UI board power fault
Electrolux dishwasher ic1 error — understanding this error code helps you decide on the right course of action for your Electrolux appliance. What Does Error Code iC1 Mean on an Electrolux Dishwasher? Error code iC1 on Electrolux dishwashers indicates a power supply fault to the user interface (UI) board. The main control board provides low-voltage […]

Answer to continue safely
Is it safe to keep using?
No. Without proper power to the user interface, you cannot reliably start, stop, or cancel cycles. Running the dishwasher with an intermittent UI power fault could result in a cycle that cannot be controlled or canceled.
Can I reset the code?
Yes. A power cycle may temporarily restore the UI board if the fault is due to a transient power glitch. A hardware failure will cause iC1 to reappear immediately or within minutes of operation.
When to stop immediately?
Stop if you notice: The display remains dark or garbled after a full 5-minute power cycle, You detect a burning smell from the control panel area.
Symptoms You May Notice
Display is dim or partially lit
The UI panel receives insufficient voltage, causing the display to appear faded, partial, or to flicker between readable and blank states.
Buttons respond inconsistently
Some button presses register while others do not, because the UI board intermittently loses its power supply during operation.
Machine beeps but display remains dark
The main board may signal an audible alert while the UI display cannot illuminate, indicating the power feed to the display circuitry has failed.
iC1 shows briefly before display goes blank
The fault code flashes on screen momentarily before the UI board loses power entirely, leaving the panel dark and unresponsive.
Possible Causes
Failed power supply on main board
The transformer, voltage regulator, or fuse on the main control board that supplies low-voltage DC to the UI board has failed.
Requires ProfessionalBroken wire in door harness
A conductor in the flat cable that passes through the door hinge has fractured from repeated flexing, interrupting the power connection to the UI board.
Requires ProfessionalShort circuit on UI board
A failed component on the user interface board is drawing excessive current, causing the power supply rail to collapse below the minimum operating voltage.
Requires ProfessionalSafe Checks You Can Do
-
1
Full power cycle
Turn off the circuit breaker and wait 5 full minutes. Restore power and observe whether the display initializes normally with all segments lighting up during the self-test.
Watch the initial power-on sequence carefully — all display segments should flash briefly before settling.
-
2
Check household power
Plug a known-working device into the same outlet or circuit to confirm it provides consistent power. Voltage dips in the home electrical system can cause board power faults.
If other appliances on the same circuit also behave erratically, the circuit itself may need an electrician.

3
Inspect for obvious damage
Look through the door vent slots for signs of moisture, burn marks, or smoke residue on the control panel area. Any visible damage confirms a hardware failure.
Do not open the door panel yourself if you see burn marks — this indicates a component that may have shorted.
When to Call a Professional
Contact a qualified technician if:
- No voltage measured at the UI board connector pins from the main board output
- Visible burn marks, swollen capacitors, or discolored areas on either control board
- The harness cable shows a visible break or frayed conductors at the door hinge point
