Clean Light flashing

Our Kenmore dishwasher made a grinding noise during its cycle and since then the clean light is flashing and it does not work. When I look it up in he manual it says it has malfunctioned and to call for service - can we fix this ourselves?

Does it blink 7 times?

If it does, perform the troubleshooting as instructed in the Tech sheet (page 2) and post the results.
