From the web:
I used towels to absorb the water then I checked and cleared each hole on each arm that sprays water. I removed the trap on the bottom in the back and cleaned that piece, plus I used a bottle brush to clean down in trap then put the trap back on, checked hoses for kinks and then ran a hot water rinse cycle with 1 cup CLR. works fine now. you know a dishwasher is just a sanitiser there is no garbage disposal in it.
