Do ice makers need to be drained?
Yes, draining your ice maker is an important maintenance task that significantly impacts both performance and hygiene. Most portable countertop ice makers don’t connect to a drainage system, so it’s highly advisable to drain the whole content inside your countertop ice maker, at least after 3-4 days of use.

Water stagnation in the reservoir quickly becomes problematic. Left unattended, it creates the perfect environment for bacteria and mold growth, while minerals in your water gradually accumulate as scale deposits. This buildup can reduce your ice maker’s efficiency by up to 25% and negatively affect ice taste and clarity. Quick summarize, when you find your ice maker smell bad, it’s time to drain the ice maker.
This problem is mainly for countertop ice makers, because built-in and undercounter ice makers make use of a proper drainage system that does the job. Still, it is recommended to know how to clean ice maker, and do a proper cleaning for both types of ice makers at least one per month.

The benefits of regular draining are not only for hygiene. Properly maintained ice makers typically last 2-3 years longer than neglected units and operate with 15-20% better energy efficiency. Just read my article of “How to drain an ice maker?”, the process of draining is super easy to do and pose no risk to break your ice maker. Don’t do the manual process, and get ready to replace the ice maker soon.
Remember to read your model’s manual for manufacturer recommendations on drainage procedures, as requirements may vary slightly between different ice maker designs (though it’s not significant).
