Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
this is a drain problem,
E:13 Er:13P:15Drain pump time exceededFaulty drain pump, wire harness, hose.
it means there is still water in the tub. in the front right bottom corner there should be a round cap. remove that and unscrew the drain trap and pull it out and clean it, this should reset the board , be carefull there will be water get some towels ready, let me know if that works, thanks Bryan
