What Your Machine Is Actually Telling You
E6 specifically flags the door position sensor (as opposed to E2 which flags the lock mechanism). The board uses two separate systems to verify door status:
1. Door position sensor (E6) — a reed switch/magnet pair that detects whether the door is physically closed.
2. Door lock mechanism (E2) — the locking system that prevents the door from being opened during a cycle.
How the reed switch works: A small magnet is embedded in the door. When the door closes, the magnet aligns with a reed switch (a tiny glass tube containing two metal contacts) in the frame. The magnetic field causes the contacts to close, sending a signal to the board.
Why E6 triggers:
1. Magnet dislodged (30%) — the magnet has shifted or fallen out of its mounting.
2. Reed switch broken (25%) — the glass tube has cracked or the contacts have failed.
3. Magnet/switch misaligned (20%) — due to door sagging or hinge loosening.
4. Wiring failure (15%) — wire to the reed switch is broken.
5. Board input failure (10%) — board can't read the switch signal.
E6 vs E2: E6 means "I can't tell if the door is closed at all." E2 means "the door seems closed but I can't lock it." E6 is about detection, E2 is about locking.

What You're Probably Seeing Right Now
- E6 appears with door firmly closed — the sensor can't see it.
- The machine won't start at all — it thinks the door is open.
- E6 is intermittent — works some days, fails others. Misalignment getting worse.
- The door seems loose — hinges have shifted.
- E6 appeared after the machine was bumped or moved.
DIY Fix — From Easiest to Hardest
1
Close Door Firmly (30 seconds)
Push the door at the hinge side and lock side simultaneously.
**Check for clothes caught in the gasket** — even a small piece prevents full closure.

Power Reset (2 minutes)
1. Unplug for 5 minutes.
2. Plug in, close door, start a cycle.
3. If E6 clears — transient event.

Check Door Alignment (5 minutes)
1. Observe the door as it closes — does it sit flush all around?
2. Check hinge screws — tighten if loose.
3. If the door has dropped: adjust hinge position.
4. The **magnet and sensor must align within 5mm** for reliable detection.

Locate and Check the Magnet (5 minutes)
1. Look at the door edge near the lock area.
2. The magnet is embedded in the door — you may see a small disc or feel it with another magnet.
3. Has it shifted? Is the mounting broken?
4. If the magnet has fallen out: **reglue with epoxy** in the correct position.
**Cost: Free** if you have epoxy. New magnet: $5-10.

Test the Reed Switch (5 minutes)
1. Unplug. Access the reed switch (usually near the door frame).
2. Disconnect wiring.
3. Test with multimeter: hold a magnet near it.
4. **Continuity with magnet** = switch works.
5. **No change** = switch is dead. Replace ($5-15).
**Handle carefully** — reed switches are fragile glass tubes.

Replace the Reed Switch (10 minutes)
1. Remove the old switch (1-2 screws or clip).
2. Install new switch in the exact same position.
3. Reconnect wiring.
4. Test with door open/closed — verify the board sees the change.
**Alignment is critical** — even 1cm offset can cause intermittent failure.

When to Call a Pro
- •Reed switch and wiring fine — board input failure: $120-$350.
- •Door frame warped — door or frame replacement: $100-$300.
- •Hinge broken — hinge replacement: $50-$150 installed.
