含义
错误代码 27 表示洗衣机门开关（门检测微动开关）功能异常。主控板在检测门状态时收到不稳定或矛盾的信号——门开关可能在程序运行中反复通断，或者门已关闭但开关始终输出”开门”状态。控制器无法确认门的安全状态，因此暂停所有操作。
常见原因
- 门开关微动触点氧化或积碳，接触电阻增大导致信号不稳定。
- 门开关的机械触发杆（推杆）磨损、变形或断裂，关门时无法可靠推动微动开关。
- 门开关连接线束插头松动、端子锈蚀或线束内部导线断裂（常见于门铰链处反复弯折）。
- 门铰链松动导致门体下沉，门钩与门开关推杆的配合间隙过大。
- 主控板门开关检测回路的上拉/下拉电阻或光耦损坏，导致信号检测异常。
自助排查
- 反复开关洗衣机门 5-6 次，利用机械动作清除触点表面的轻微氧化。注意开关门时应听到微动开关的清脆”咔嗒”触动声。
- 用手电筒观察门钩和门框上的开关触发孔，确认门钩在关门时能对准并推入触发孔内。
- 检查门铰链螺丝是否松动。若门体有明显下垂（门缝上下不一致），用螺丝刀紧固铰链固定螺丝，将门体调整回正位。
- 若听到门内有异物滚动声，可能有硬币或小物品掉入门开关机构内阻碍触发，需拆下顶盖清理。
- 若门开关机械动作正常但故障依旧，可能是开关触点严重氧化或线束断路。请联系通用电气售后更换门开关组件。
English
Meaning
Error code 27 indicates a door switch malfunction. The main control board is receiving an unstable or contradictory signal when reading the door state — the switch may be toggling on and off during a running cycle, or the door is physically closed but the switch consistently outputs an “open” signal. The controller cannot confirm the door’s safe state and pauses all operations.
Common Causes
- The door switch microswitch contacts are oxidized or pitted with carbon buildup, causing increased contact resistance and unstable signal.
- The door switch’s mechanical actuator (push rod) is worn, deformed, or broken, so closing the door cannot reliably depress the microswitch.
- The door switch wiring harness connector is loose, the terminals are corroded, or a wire inside the harness is broken (common at the hinge area where the harness repeatedly flexes).
- The door hinge is loose, causing the door to sag and the door hook’s engagement gap with the switch actuator to widen beyond tolerance.
- The main control board’s door switch detection circuit has a damaged pull-up/pull-down resistor or optocoupler, causing abnormal signal detection.
Self-Check Steps
- Open and close the washer door 5–6 times firmly — the mechanical action may clear light oxidation from the contact surfaces. Listen for a crisp “click” from the microswitch each time the door closes.
- Use a flashlight to observe the door hook and the switch actuator opening on the door frame. Confirm the door hook aligns with and pushes into the actuator opening when closing.
- Check whether the door hinge screws are loose. If the door visibly sags (uneven gap at the top and bottom of the door), tighten the hinge screws with a screwdriver to realign the door.
- If you hear rolling sounds inside the door area, a coin or small object may have fallen into the switch mechanism and is blocking the actuator. Remove the top panel to clear the obstruction.
- If the switch mechanism moves normally but the fault persists, the switch contacts may be heavily oxidized or the harness may be broken. Contact GE after-sales service to replace the door switch assembly.
