Your video doesn't quite show how many flashes in the sequence.
six orange flashes means the CD tray door is down, seven orange flashes (the 5B00 error) can be addressed as below. Good Luck.
5B00/5B01 - Orange and green light blinking 7 times Description: A service error has occurred. Resolution: 1. Turn off the printer. 2. Disconnect the power cable. 3. Open the printer cover. 4. Check for any orange protective tape or white polystyrene and remove if necessary. 5. Check that there are no foreign objects in the printer (such as a paper clip) and remove if necessary. 6. Close the cover. 7. Reconnect and turn on.

Unless you have already tried the fix on this site, please see if you can reset your dishwasher. It appears to be linked to dishwasher not being able to heat water to correct wash temperature.

flashes seven times, it usually indicates a problem with the water temperature.

? Seven flashes: Defective printhead
Remove and reinstall the printhead.
Also, ensure that the protective cap has been removed. If reinstalling the printhead does
not resolve the problem, replace it with a new one.

Now, keep in mind all dish washers are not alike and have different panel options. If you do not have the same set up that I have mentioned, the tech sheet for your dishwasher will explain the touch pad functions. The tech sheet is located behind the lower toe panel under the door and lists the proper sequence of buttons to push for diagnostics and troubleshooting.

NOTE: Sometimes the tech sheet is located behind the inner door panel. You will need to remove the screws securing the inner panel to access it if this is the case. Make sure you turn off the main power breaker before doing so.

Sometimes this can be a momentary glitch in operation. However, if the problem keeps reoccuring the number of flashes is an indication of which circuit is causing your problem. Again, refer to your tech sheet to determine this.

If you have any questions, please let me know. I hope this helps you solve your problem.

I believe that 7 amber flashes refer to a cartridge error. Check that the cartridge is seated correctly.
