Many units use a dispenser with a wax motor, it is fairly common for these to burn out.
Here is a good site with basic dishwasher repair info.

Remove door cover from inside and replace the wax motor?
I would check the unit for a mechanical fault also could check the wax motors for resistance. Most of them are around 2,000 ohms.
nothing to clean or unclog?
Probably not but worth taking a look.
