indicated low water pressure from your external supply or blocked filters in the fill hose. turn water off, remove hose and check filter in end of hose - it is just a bit of gauze. also look into the valve and clean out if needed

1. Set the washing machine on the highest water level, temperature on hot and the wash cycle to normal.
2. Fill a gallon jug with hot tap water. Once the cycle begins, let it run for a minute or two, then stop the cycle, open the lid and slowly add the gallon of hot tap water. Don't overfill — you just want to raise the water level so that it is able to reach and clean the inside top rim.
3. Add 2 to 4 cups of household chlorine bleach and restart the cycle. In a couple of minutes, stop it again and just let it sit for at least 30 minutes. Afterward, let the cycle finish, and open the lid to air out the inside.

this is possible due to a bearing collapse or bearing spider broken. this causes drum pulley to be out of line and the belt comes off

There are a lot of reasons could cause this issue. Could you provide us more details (if you have) which cycle's stage "takes" this time (filling water, washing process,draining etc... ) You answer will allow us to direct you the solution. Good luck !
