Here are your parts

Here is a manual although it does not show your unit I believe the pump is the same.

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.

Could be just the pump needs cleaning out re: filters and chopper /impeller.

Most units fill to just below the heating element.
If you are not sure that iot is getting enough water even with the new valve you could add a quart or so of water after each fill. If it then runs OK you know that you have a fill problem. Just be careful that you do not overfill the unit.
