What i67 means on a Electrolux dishwasher

The i67 error code on an Electrolux dishwasher indicates a Heating System Error 3, a fault condition specifically related to the line relay on the main printed circuit board (PCB). The line relay is responsible for switching power to the heating element during wash and dry cycles. When this relay becomes burned or mechanically stuck, the control board loses the ability to regulate heating accurately, triggering the fault. Unlike some error codes that halt the cycle immediately, i67 is stored only in service mode and the wash cycle continues to run, meaning the machine may complete a cycle but without proper heating performance.

The two primary causes identified for this error are a failed line relay on the PCB and a damaged wiring harness or connector between the board and the heating circuit. A burned relay is typically the result of sustained electrical arcing at the relay contacts, which can occur when the heating element draws higher-than-normal current over time. A stuck relay, by contrast, may remain closed when it should open, or fail to close at all. In either case, the PCB cannot correctly execute heating commands. Wiring harness damage, including corroded terminals, pinched wires, or loose connectors, can produce intermittent or complete loss of signal to the relay circuit, generating the same stored fault.

Because the alarm is stored in service mode only, a technician must access the service diagnostic menu to confirm the fault is present. Visual inspection of the relay on the PCB for discoloration or burn marks, along with continuity and voltage checks on the associated wiring harness and connectors, are the recommended starting points for diagnosis before replacing any components.

Common causes of i67

  1. 01

    Burned line relay on the PCB

    Part replacement

    The line relay on the main control board can burn out due to electrical arcing or sustained overload from the heating circuit. Look for visible discoloration, pitting, or burn marks on the relay or the board surface around it.

  2. 02

    Stuck line relay on the PCB

    Part replacement

    The relay contacts can become mechanically stuck in the open or closed position, preventing the board from properly switching power to the heating element. This may not show visible damage and often requires electrical testing to confirm.

  3. 03

    Damaged wiring harness

    Part replacement

    A pinched, chafed, or broken wire in the harness connecting the PCB to the heating circuit can interrupt the signal path and trigger this fault. Inspect the harness routing for signs of wear or physical damage.

  4. 04

    Corroded or loose connector

    Wiring / connection

    Connector terminals exposed to moisture and heat can corrode or work loose over time, creating intermittent continuity faults in the heating circuit. Check all connectors on the harness for corrosion, bent pins, or poor seating.

Frequently asked questions about i67

What does i67 mean on a Electrolux dishwasher?
The i67 code on an Electrolux dishwasher signals a Heating System Error 3, pointing to a fault in the line relay on the main PCB or a problem with the wiring harness and connectors serving the heating circuit. The dishwasher will typically continue and complete its cycle, but heating performance may be compromised. The fault is stored in service mode and must be retrieved through the diagnostic menu. A technician should inspect the relay and wiring to determine the exact cause.
Will resetting my Electrolux dishwasher clear the i67 error?
A basic power reset may temporarily clear the displayed indication, but because i67 is stored in service mode, the fault record will remain until the underlying cause is repaired. If the relay or wiring issue is still present, the error will return. A proper repair and then a service mode reset is the correct way to clear the fault permanently.
Can I still use my dishwasher when the i67 code appears?
The dishwasher is designed to continue its cycle when i67 is active, so it will not necessarily stop mid-wash. However, if the heating circuit is not functioning correctly, dishes may not be cleaned or dried as effectively. Continued use with a burned or stuck relay could put additional stress on the control board, so having the issue diagnosed promptly is advisable.
Is the i67 error on an Electrolux dishwasher a safety concern?
A burned relay on a circuit board can carry some risk if left unaddressed, as damaged electrical components can degrade further over time. While the dishwasher may continue to operate, it is good practice to have the PCB and wiring inspected by a qualified technician as soon as possible to rule out any ongoing electrical hazard.
How much does it cost to repair an Electrolux dishwasher showing error code i67?
Repair costs vary depending on whether only the wiring and connectors need attention or the entire PCB requires replacement. Wiring repairs or connector cleaning are generally lower-cost fixes, potentially in the range of $75 to $150 including labor. A full PCB replacement, including parts and labor, typically ranges from $200 to $450 depending on the specific model and local labor rates.
