How do I test a portable dishwasher's features? - maytag performa dishwasher pdb2600awe

I have an old dishwasher Maytag Performa 5.5 years laptop for my apartment. I moved into a new apartment, which has a built-in dishwasher, so I'll probably sell.

Normal cycle that what works, I used to perfect, but the dishwasher has three properties, temperature, drive, prolonged washing and drying heat, which is never used.

So I do not know if the work is now working (or never true, for that matter). How can I test whether these functions, so you can be who they sell it to me honestly, if these features?
