I first ordered a control board from Appliance Parts Pros thinking that would be the most logical problem. After installing new control board I found that it did not correct problem. I then ordered the control panel which did fix dishwasher. I removed new control board and installed original control board and dishwasher display and buttons still worked. I sent new control board back to Appliance Parts Pros and did receive full refund for control board. There are not many companies that will do this for there customers but Appliance Parts Pros is they exception. There customer service is excellent and they are a great company to do business with.
