If the panel turns off and returns to the start during the wash, distinguish a power interruption from a control restart. A pause with active indicators calls for a different diagnosis.
Observations you can keep
Note what it was doing when it shut off, whether other lights in the home changed, and whether the display returns to the program or the initial selection. Also record any recent changes to connections or the appliance's location.
You do not need to repeat the incident with more laundry or higher temperature to identify a pattern. If there is a smell or signs of heat, follow the procedure for burning or smoke.
External power and internal electronics
A poor connection, a power interruption, or a problem with the power supply and control can produce similar symptoms. If a protection device trips, use the electrical trips diagnosis and do not keep resetting it.
Electrolux refers power-supply problems to an electrician and advises against extension cords in its guidance on circuit load and connection. The specific circuit capacity depends on the local installation.
If the power supply is verified
Checking the board, power supply, and connections must take into account external loads that can cause the failure. Do not install a generic stabilizer to compensate for an unidentified fault.
How to resume a program after an outage varies by model. Follow its manual and check which operations actually finished before considering the load washed.
Keep track of whether the shutdown clears the selection or resumes the cycle; that difference helps evaluate power and control.
