Error Code: SQUARE WITH ONE VERTICAL LINE Difficulty: Easy
Problem: Line dry; laundry should be hung on a clothesline.
How to Fix SQUARE WITH ONE VERTICAL LINE Error (Step-by-Step)
- Find the symbol on the garment’s care label; it is a square with a single vertical line inside.
- This symbol means the item should be hung on a line to dry and must not be put in a tumble dryer.
- After washing, remove the garment from the washing machine and confirm the error stays cleared during a full test cycle.
- Hang the item on an outdoor clothesline or an indoor drying rack.
- You can use a hanger for shirts and dresses or clothespins for other items.
- Make sure there is adequate space around the garment for air to circulate freely.
- Allow the garment to hang until it is completely dry to the touch.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
