How to fix LG1518CS washing machine?

It runs through the cycle but stop at the rinse mode or 10 mins into the cycle code OE comes up. I pulled all the hoses off and found no restrictions and no kinks. I put back together and it worked fine it went through the rinse mode and drained all the water. But after about 3 loads it happened again. I can here some humming noise when it reaches the rinse mode but no water is being pumped out.
