Dishes not being washed, water below heater element

I attempted to fix it about a year ago. Took apart the screen center stem and water spinner.
I could not find anything wrong. The machine was used very infrequently over the years. Recently my wife approached me again to fix it and knowing I didn't find any thing the first time: I took the lower panel strip off and found the translucent belt broken. I found your site matched up a belt size and ordered it. Three days later it arrived, I installed it and everything seems to work. The water drains and I'm back in business. It was so easy I was embarrassed I did not fix it the first time.
