Pull the dishwasher out from the cabinet. Have a towel ready, tile the unit back and let drain. Put back in, and see if error returns. If it does, you will have to check for where it is leaking, and replace that part. I hope this information has assisted you. Please give a good to great rating if I have done so.. If not, please respond back for further assistance.....Thank you
