Bosch Dishwasher "Add Salt / Rinse Aid" Error

[Coolhandluc]

I found a similar thread here that indicated the control module in the back/right bottom of the unit had gone bad and wondering if this is the likely culprit for my model? Details below:

Bosch SHXM78W55N/01 (Super Silence Plus 42 dBa). Purchased in 2017. No issues previously but suddenly stopped functioning. "Add Salt" and "Rinse Aid" continuously blink on control panel. The On/Off button will beep but doesn't do anything. No other buttons (cycle selection, etc) are functional. A hard reset cannot be performed because none of the buttons work. I've reset power at the breaker numerous times. Talked to Bosch and the lady on the phone (not a technician) indicated her system says it could be a "sensor". Can't get someone out here until much later in January and would love to have it fixed sooner since we're dealing with a newborn here.  

The other thread indicated the purchased their part from PartsDr website for the exact same issue, but their links aren't applicable to my model. I found this power control unit for my model on their site. Does anyone know if this is what I need to correct this problem? Looks relatively easy to replace once I pull the dishwasher from the cabinet. 

Thank you and Merry Christmas to you all.

The simple reset is to press and hold start button for 5 sec.

To enter the special function menu to retrieve error codes:

then:

let us know if there are any error codes.

Thank you - unfortunately Bosch tried to have me do that but the start button doesn't function at all. In fact, none of the buttons do anything except the "On/Off" button still makes an audible beep though it doesn't actually turn the unit on or off. So I don't believe I'm able to force a reset. 

It's very similar to this:

Closing this out for anyone who has a similar issue in the future. I linked another thread above that is related. 

My Bosch dishwasher required a new Main Board (Power Control Unit on back right where cord connects) and Display Board (the component w/ function buttons in the door). The likely culprit was a 'brown out' or power event that essentially ruined the boards. I plan to install a whole home surge protector.

Symptoms: Dishwasher abruptly stopped functioning and only flashed "Add Salt" and "Rinse Aid" repeatedly on display. None of the buttons functioned so the unit could not be reset and I could not pull error codes. Turning on/off at the breaker had no effect.
