Turn off the machine and unplug it before checking. This keeps the inspection safe.
Look at the drain pipe behind the machine and make sure it is not bent, blocked, or pressed against the wall.
Look at the drain outlet right bottam of the machine and open it see there is any coin or dirty stuck
Small cloth pieces, lint, or dirt can block the drain path and stop water from flowing out properly.
If water is still inside, drain it slowly into a bucket to avoid spilling on the floor.
Start the machine again and check if water drains normally. If not, the drain pump may need technician support.
Clean the drain area regularly and avoid washing items that release too much lint.
