What F3 E1 (110 / Whirlpool-built) Means
F3 E1 means the 110-prefix Whirlpool-built control is no longer getting a believable water-level reading; the sensing works through a small air hose running from the bottom of the tub up to a pressure switch on the machine control board, and a kink, split or blockage in that hose reads as a sensor fault.
Common Causes of F3 E1 (110 / Whirlpool-built)
- The air hose between tub and pressure switch kinked, split or pinched
- Detergent residue or lint blocking the hose or its tub port
- The pressure switch itself, which on this platform is part of the machine control board
🔧 One Safe Check You Can Try
This one lives inside the cabinet, so leave it alone with the washer plugged in — what you can do is note whether the tub is over-filling, under-filling, or filling normally, because that detail steers the diagnosis.
⚠ Why You Shouldn't Go Further Than That
- Because the switch is built into the control board here, a sensing fault and a board fault can carry the same price tag — worth confirming before ordering.
- The hose runs alongside console wiring that stays live whenever the cord is connected.
- A hose reconnected slightly out of position reads wrong again immediately, so it is not a job to rush.
