I have a lg dishwasher model number LDP7808BD. Just now turning a year old. But forwards the end of every cycle I get error code be and it stops. I checked the code and says bubble error. But thin is I opened the door as soon as get the error and there are no bubbles and very little water in there. I have also checked that it’s level cause that’s the other cause for that error. The dishwasher is level. There for a few cycles it sounded like it had a grinding noise at certain times in the cycle but it’s not doing it anymore. Does anyone have any advice for what it could be?
