No water from front of fridge

Question

Model ED22RFXFW00

serial # SH4647940

I do not want to break the plastic surround, need a little help taking unit a part as likely switch broken for the no water issue. Unit really could use a good cleaning and I know that we have been having issue with ice and frost building up by enterance to door. Is there a downloadable service bulletin or parts diagrams???

Thanks much Chris
