LG1815CS Not draining?

On my LG1815CS Washer the OE Code comes on when it reaches the rinse mode. I removed all hoses and found no restrictions, my drain filter has nothing in it and no hoses are bent.I put it back together and it went through the whole cycle it rinsed and drained great. But after about 3 loads the code came on again.10 minutes into the cycle this happens this must be the rinse cycle. I here a noise but no water is being pumped out. Has anyone experienced any thing like this.
