Greg, We presume you mean the "clean" light is "blinking" seven(7) times. This is an indication that the heater element could not increase the water temperature in the prescribed time. This could be due an issue as simple as low water temperature (water temperature needs to be 120 to 130 dgrs.F. in the bottom of the tub on the first fill of a cycle). It could also be due to an "open" heater element, thermostat, or a faulty control board.
You will need to reset the control board by conducting the Service Diagnostics Cycle,"To start the Service Diagnostics Cycle, press the following keys, in order, in less than 6 seconds, while in standby: Heated Dry, Normal, Heated Dry, Normal" . If there are any failed components the control will stop the program when the failure is detected. If there are no faults detected, check and increase the water temperature, and try running a regular cycle again.
If need be you should find the tech data information sheet attached to the back of the lower kick plate or the lower frame of the dishwasher.

Greg, You're Welcome.

Just remember to run the hot water faucet at the kitchen sink before you start the dishwasher, That will purger most of the cold water in the pipes so you'll have a good water temp. in the tub.

Thanks Again,
