If you replace your dishwasher these noises may be unlike your old machine, and if you have installed a dishwasher for the first time they might not be the noises you expected.
The noise of water gurgling and sloshing around is completely regular, these sounds might seem rather noisy if you are not used to having a dishwasher although you will soon get used to them.
Water can in many cases make a hissing sound as it enters the machine and a sloshing or swishing noise as the spray arms rotate. The machine will also repeat this process several times during the cycle.
A pounding sound could be de to the sprayer hitting into an object that is hanging down or an oversized plate. Alternatively, it could be the drain pipe banging into the wall or cabinets.

Humming can additionally be heard as a result of the fan keeps the dishwasher pump motor cool while it runs.
Plenty of dishwashers also make use of a grinder that can produce a humming noise intermittently during the cycle.

Although plenty of machines can make a soft grinding noise as part of their routine operation if your dishwasher suddenly starts making a loud or strange grinding noise this is generally not a good sign and therefore needs further investigation.
The most common cause will be an item such as an olive stone or corn kernel is caught in either the the waste disposal or the drain impeller, and therefore is knocking against the blades. in this case you need to pause the cycle and have a look. If you discover anything, remove it carefully before re-starting the dishwasher.

A rhythmical knocking is more often than not the result of the spray arm hitting something inside the machine and could be easily sorted by adjusting your dishes. Items descending from the shelves is the most likely cause of this.
It can be a good idea to check that the arm is able to spin without obstruction regularly before starting your machine to stop this from being an issue as it also means your dishes don’t get cleaned so well.
