F3E1 — Pressure Sensor (Water Level) Fault

How to fix it
- Unplug the washer.
- Locate the pressure (air) hose — a small clear or black hose running from the bottom side of the outer tub up to the pressure sensor on the main board.
- Disconnect both ends and blow it clear. If kinked, replace.
- Reseat the connector on the pressure sensor.
- Plug in and test. If the code returns and the pressure transducer is on the main control, replace the main control board.
Why it happens
Typical signs: Washer drains continuously, even when off · Won't fill at all, or overfills · F3 E1 immediately on Start · Drain pump runs nonstop until unplugged
- Clogged pressure (air) hose Detergent or water in the small clear hose between tub and pressure sensor distorts the reading.
- Failed pressure transducer Sensor on the main control board has failed.
- Loose harness to pressure sensor Connector unseated during prior service.
- Failed main control board On boards where the pressure transducer is integrated, the whole board needs replacement.
