How can I fix my F&P Smart Drive 703 won't rinse or spin?

Has worked faultlessly for years, now it stops at the rinse cycle, pumps out a little water, waits a while, then beeps continuosly with different lights on. Are these lights fault codes? Does anyone know what the problem is? I live in the country so a tech will cost a fortune. I'm a single dad with two boys in high school so I need it fixed fast, can someone please help?
