The sound is the dishwasher draining into the sink drain. It is a normal sound.
Nothing because it is empty
I would recommend the Samsung DMT800RHS because according to the information on this site, http://dishwasher-review.toptenreviews.com/, the brand of dishwasher is a good brand.
No, most are not dishwasher safe. You would need to wash them by hand.
All dishwashers in the US are hooked up to a hot water supply line only. Cold water does nothing for cleaning dishes.
This food processor is dishwasher safe,I would suggest the top rack of the dishwasher. The base needs to be hand washes. All attachments are dishwasher safe.
Logically, I don't think you can cook mackerel in a dishwasher as I would have thought you would only have been able to wash it at the very least.
Maybe, but it would be hard for the dishwasher to clean all of the inside surfaces and rinse them well.
I've read in several places that pouring vinegar down the dishwasher drain (a lot) and then running the empty dishwasher will kill the ants and keep them from coming back.
When using an automatic dishwasher at your facility, you must follow the instructions as per the manufacturer's manual. If this is not available, you may use the dishwasher in the same way as you would at home.
The pump in the dishwasher should keep the water from getting into it.
No you can't cook food in a dishwasher because a dishwasher is for washing not cooking. Even if you tried to cook in one, it would be washed away by the water being spread around the washer, so all you would end up with is just a clean plate that you put the food on.
So it would clean by themselves and save time
