if you open the top drawer the model number should be on the unit right face frame.
ok thank you .
If it is not completly draining .
I would suspect that the top unit has a partcial drain line clogged.
The drains Y into one drain ,but both units have seperate drain lines.
You will need to pull the unit out and check the drain lines.
This is an Appliance repair web site .
Every customer that ask`s a question is able and ready to work on the appliance .
Or they would not come to this site.
Appliance repair is not just a snap of your fingers and the appliance is repaired.
Im sorry that you thought that.
