The cleaning LED flashing and dishwater not working

The blinking clean light is an indication of a malfunction. Which circuit is causing the problem is determined by the number of flashes. Sometimes these error codes can be erroneous, however. If you wish to reset the light to see if you have a glitch, or a legitimate problem, the following link may offer you some assistance:

If the error reappears you will need to refer to the tech sheet that comes with your appliance. The sheet is usually located inside the lower toe panel under the door.

If you have questions, please let me know. I hope you find this information helpful.

PS Your dishwasher may have a different series of buttons to push to reset the error, but the steps are similar. If you do not have the same configuration as outlined in the link I provided, refer to your tech sheet.
