Water from the clothes will either be stored in a drawer style container that will have to be emptied every time the dryer is used, or pumped directly to the drain via a small hose.Identify if you have this facility.

The condenser, that looks like a mini car radiator, will need to be cleaned from time to time. Not every time the dryer is used, but it needs to be kept clean.Check it after about ten uses and you will get the idea of how often to clean it. It will be hiding down the bottom of the dryer behind a small door that can be opened for access. Check the user guide for details regarding your particular make. You may have a self cleaning condenser. Then there isn't any condenser cleaning necessary. You must identify if you have this type of dryer as condenser maintenance is vital for trouble free use.

Identify the filter at the input to the water storage drawer, if you have a storage drawer to maintain. (A hose directly to the drain cancels this necessity ). Keep this filter clean otherwise you may get false alarms to empty the water from the drawer even though the drawer is not full. This can lead to unnecessary service calls at your expense.
