Electrolux and Frigidaire share a parent and much of a platform, and the codes reflect it — the refrigeration set is effectively the same, and the laundry uses an E-numbered system where the first digit names the system and the second the specific fault. That structure is worth knowing: everything in the E1x family is water arriving, everything in E2x is water leaving. It narrows a diagnosis before anybody opens a panel.
Codes are not standardised between manufacturers, and they move between model years within one. Everything below is what these codes mean on the series named beside them — if your model is older or newer, treat this as a strong hint rather than a verdict, and send us a photo of the model plate when you book. That plate settles it, and it takes ten seconds.
Laundry shows the code where the cycle time sits. Refrigerators use the front display and the same SY-prefixed set as Frigidaire. On some laundry models the last few codes can be recalled through a diagnostic mode, which is useful when a fault is intermittent and has cleared by the time we arrive.
