Thank you for your question.
It sounds like your water level switch is going bad. This part is located directly behind the top control panel, and is actually part of the selector switch where you choose the load size. This selection correlates with how much water the switch will allow into the washer.
Below is a link to the above mentioned part. You will need to remove the front control panel to get to the switch. I would first check the connection. Make sure it is tight. But more than likely this part is failing internally and will require replacement if you deem this repair cost-effective.
I hope this answer helps, and thank you for your question.

You will need to remove the two console screws and the front control panel will then fold downward, revealing the various switches and connections.
