Whirlpool Laundry Tower F1E1 — What It Means & How to Fix It
Also shown as F1 E1, F1E2, F1 E2 on some models.
F1E1 and F1E2 on a Laundry Tower are control faults — Whirlpool labels them ACU and MCU — so reset power and schedule service if either returns.

Whirlpool gives the potential cause of F1E1 as "ACU (Control Fault)" and of F1E2 as "MCU (Control Fault)". These are the tower's control units; the only owner step is cycling power.
Whirlpool lists this code for both the washer and the dryer of the Laundry Tower with the same potential cause.
