Electrolux Range Error Code E015

Loss of Display tail #1 on ESEC

Loss of Display tail #1 on ESEC. May also indicate the ESEC-UIB is not receiving a synchronization signal from the ESEC-Relay Board.

First step from the service manual

Check connection P2 on ESEC-UIB and P2 on ESEC Rotary HI Board (RF). Check if J2 pin 5 on the ESEC-Relay Board is wired to P4 pin 5 on the ESEC-UIB. If wiring is good and the problem persists, replace the ESEC-UIB. If the problem persists, replace the ESEC-Relay Board.

What E015 means on a Electrolux range

Error code E015 on an Electrolux range indicates a loss of communication on Display Tail #1 connected to the ESEC-UIB (User Interface Board). The ESEC system is an electronic control architecture that divides range functions across multiple boards: the ESEC-UIB handles the user interface and display, while the ESEC-Relay Board manages power switching and synchronization. When E015 triggers, it means either the display tail connection has failed or the ESEC-UIB is not receiving the required synchronization signal from the ESEC-Relay Board. This synchronization signal travels from J2 pin 5 on the ESEC-Relay Board to P4 pin 5 on the ESEC-UIB, and any break in this path will trigger the fault.

The most common physical cause is a loose, damaged, or disconnected wiring harness at connector P2 on the ESEC-UIB or at P2 on the ESEC Rotary HI Board (RF). Vibration over time can work connectors loose, and heat cycling in a range environment can cause connector pins to oxidize or back out of their housings. The specific sync signal wire between J2 pin 5 and P4 pin 5 should be inspected for continuity and secure seating before any board replacements are attempted.

If all wiring checks out and connections are secure, the fault points to a failed ESEC-UIB as the next most likely component. If replacing the UIB does not resolve the error, the ESEC-Relay Board itself is the final suspect, as it may be failing to generate or transmit the synchronization signal correctly.

Common causes of E015

  1. 01

    Loose or disconnected connector at P2 on ESEC-UIB

    Wiring / connection

    The wiring harness at connector P2 on the ESEC-UIB may have worked loose due to vibration or heat cycling. Inspect the connector for secure seating and signs of corrosion or bent pins.

  2. 02

    Loose or disconnected connector at P2 on ESEC Rotary HI Board

    Wiring / connection

    The corresponding P2 connector on the ESEC Rotary HI Board (RF) is an equally likely point of failure. Check this connection at the same time as the UIB connector.

  3. 03

    Broken or missing sync signal wire between J2 pin 5 and P4 pin 5

    Wiring / connection

    The synchronization signal from the ESEC-Relay Board travels on a specific wire from J2 pin 5 to P4 pin 5 on the ESEC-UIB. If this wire is damaged, disconnected, or was never properly routed, the E015 fault will occur.

  4. 04

    Failed ESEC-UIB

    Part replacement

    If all wiring and connections are verified to be correct and the error persists, the ESEC-UIB itself may have an internal failure and will need to be replaced.

  5. 05

    Failed ESEC-Relay Board

    Part replacement

    If replacing the ESEC-UIB does not clear the fault, the ESEC-Relay Board may be failing to generate or transmit the synchronization signal. Replacing this board is the final diagnostic step.

Frequently asked questions about E015

What does E015 mean on a Electrolux range?
E015 indicates a loss of the Display Tail #1 connection on the ESEC-UIB, or that the ESEC-UIB is not receiving a synchronization signal from the ESEC-Relay Board. This is a communication fault within the range's electronic control system. It can be caused by loose wiring connectors or a failed control board. The range may not function normally while this fault is active.
Can I fix the E015 error on my Electrolux range myself?
A knowledgeable DIYer can begin by checking the wiring connectors at P2 on the ESEC-UIB and P2 on the ESEC Rotary HI Board, as well as verifying the wire between J2 pin 5 and P4 pin 5 on the relay board. If the connectors are secure and the wiring is intact but the error persists, board replacement is required, which involves working near high-voltage components. Board replacement is generally best handled by a qualified technician.
Is it safe to use my Electrolux range while it shows error code E015?
It is not recommended to continue using the range while E015 is active. A loss of communication between control boards can cause unpredictable behavior, including the range not responding correctly to commands. Discontinue use until the fault has been diagnosed and resolved.
Will resetting my Electrolux range clear the E015 error?
A power reset, such as unplugging the range or switching off the circuit breaker for a few minutes, may temporarily clear the display, but E015 will return if the underlying wiring or board fault is not corrected. A reset does not repair loose connectors or failed components. A proper repair of the root cause is necessary to permanently clear the code.
How much does it cost to repair error code E015 on an Electrolux range?
If the fix is simply reseating a loose connector, the cost may only be a service call fee, typically in the range of $75 to $150. If the ESEC-UIB needs replacement, parts and labor combined can range from $200 to $400 or more depending on your location and part availability. Replacing the ESEC-Relay Board carries a similar or potentially higher cost given the complexity of the component.
