When your Jenn-Air dishwasher flashes Error Code FE, it’s telling you the machine isn’t confident the door switch is closed. That tiny switch is what gives the control board permission to run pumps and heaters. If it can’t confirm a solid “door closed” signal, the cycle won’t start—or it may stop mid-wash.
What FE Actually Means (Plain English)
Inside the door latch assembly is a switch (sometimes two) that changes state when the door is fully latched. FE appears when the control detects a door that’s not truly locked, a switch that’s sticking, or wiring that isn’t delivering a clean signal. Think of it like a seat-belt sensor: no click, no go.
Typical Signs You’ll Notice
- Cycle won’t start, or pauses a few minutes in
- Beeps and FE on the display after you press Start
- You need to press the door harder than usual to get it to “catch”
- Gentle wiggle on the door makes the display flicker
Why This Happens
Most FE cases are simple: the strike and latch are slightly misaligned after a hard close, the tub gasket has grime that prevents a tight seal, or the latch micro-switch is worn. Less commonly, a bent hinge, a loose mounting screw, or a fatigued wire at the latch connector causes intermittent contact.
Safety First, Then a Quick Reset
Unplug the dishwasher or switch off the breaker for 5 minutes. This clears a false FE caused by a one-off glitch. If FE returns the moment you try to start a cycle, move on to the checks below.
DIY Fixes You Can Try (No Special Tools)
Clean and “seat” the door
Open the door and wipe the strike (the metal hook on the tub) and the latch in the door with a damp cloth. Grit here can keep the latch from fully engaging. Close the door firmly—don’t slam—and see if FE clears.
Gasket inspection
Run a finger around the door gasket to remove soap film. Look for flattened or torn sections that could prevent full closure, especially near the latch.
Level and alignment check
If the dishwasher racks want to roll out on their own, the unit isn’t level. Use the front feet to level side-to-side and tilt very slightly back so the door wants to stay shut. Re-test.
Mounting screw nudge
Open the door. Behind the top edge, the dishwasher is fastened to the counter or cabinet with 1–2 screws. If the tub has shifted, the latch and strike may be off by a millimeter. Loosen the screws a turn, gently adjust the tub so the strike lines up dead-center with the latch, tighten, and try again.
Connector reseat (only if comfortable)
With power off, remove the inner door panel (usually torx screws), locate the latch assembly, and reseat the small wire connector to the switch. Look for corrosion or a loose fit. Reassemble, restore power, and test a quick cycle.
If any step changes behavior—even briefly—you’ve found your suspect area. FE that comes back quickly after these checks usually means the latch/switch module is worn and needs replacement.
When to Call a Pro
- FE returns immediately after a careful close and clean
- Door feels latched but a light push pops it open
- You see damaged wiring or a cracked latch housing
- FE shows during a cycle (vibration can expose a marginal switch)
A technician will meter the switch, check harness continuity while moving the door (to catch intermittent breaks), verify control input, and—if needed—install the correct latch/switch assembly for your model.
Preventive Habits That Actually Help
Keep this simple and you’ll likely never see FE again.
- Close with intent, not force. A smooth, firm close protects the latch from shock.
- Wipe the gasket monthly. Soap film and crumbs keep the door from sealing squarely.
- Stay level. After a move or floor work, re-level the unit so the racks don’t self-slide.
- Mind the loads. Oversize items pressing against the door can flex it just enough to trip the switch.
- Annual mini-check. Peek at the strike and latch for wear; if the catch feels loose, replace it before it strands a load full of dishes.
Quick Action Plan (Keep It Easy)
- Power reset → clean strike/latch → verify level → nudge alignment → reseat latch connector
- If FE returns: replace the door latch/switch assembly and have wiring inspected
