If this is a front loader see that u use only washing powder for FRONT LOADING MACHINES. Also possible your detergent drawer is clogged with old dry detergent. Pull out the drawer and clean with tooth brush. Things shd be fine.

SOURCE: Hotpoint WF321 during rinse and spin, will not go into full spin as machine keeps filling with water.

you should check your pressure switch hose for a pin hole or better still just replace the hose and it should sort your problem out good luck hamstel

I ended up having to call Samsung support for this same question. Left to right two vertical bars = detergent (liquid or Powder) flower = softner, single vertical bar = bleach.

This is probably a lid cover open protection. Check to see if there is a magnet on the cover, positioned almost to centre (slightly to the right) at edge of the cover. There is some sort of plastic catch to house the magnet. If it is not there, place a magnet at the corresponding area on the washer where the plastic catch will touch when the lid cover close.

This might be Lid cover open protection. There is a small magnet at the edge of the lid cover, housed in some sort of a catch.
If the plastic housing cracked, the magnet might have dropped into the washing drum. To overcome this, place a magnet on the position where the plastic catch will contact the washer when the lid is close.
