Hi my Bosch dishwasher is 4 years old. Last week I pushed the button to turn it on and it didn't turn on. 20 minutes later, I tried again, and the red display/control buttons on top lit up as well as the orange display on the front turned on, it started and completed the wash cycle, BUT, during the cycle, the orange display was turning on and off intermitantly, but the cycle continued and finished even though front displaying was acting strange. It did this for a week before it finally refused to turn on again.

I have a feeling the control board needs to be replaced. Any thoughts?

Thanks in advance!
