When we called a repair company they suggested we get a new one because the combination of the new part and the service call would likely cost more than half the price of a new dishwasher which was over a $1,000. An online search told us how to determine the error code which let us know it was the circuit board. A you tube video showed us how to replace it. So with an $85 part from Appliance Parts Pros which arrived in one day, my 75 yr old husband and I fixed it ourselves and it is working great.
