I keep my little Follett humming like a champ by treating descaling like routine maintenance, not a crisis fix. In practical terms, I aim to descale every three months if my tap water is on the harder side, or every six months if I know the water’s soft. Hard water speeds up scale buildup — look for white crust on the evaporator, slower
Ice production, cloudy or off-tasting cubes, or machines that seem to
run longer between batches. Those are the red flags that mean you don’t want to wait.
When I actually do the job, I follow the manual and use a Follett-approved descaler or a manufacturer-recommended product; acids like citric or sulfamic can work but only if the manual allows them. The basic flow is: shut power off, drain the machine, apply the descaler to the affected areas and let it soak or circulate per instructions, then rinse thoroughly and sanitize before putting it back into service. I also replace any inline filters and check the water inlet screen — filtered water dramatically slows scaling. If you live somewhere with hard water (above ~7 grains per gallon, which is roughly 120 ppm), consider a water softener or RO for the ice machine to stretch the time between descaling.
I tinker with
mine twice a year when things are quiet, and more often if guests are coming or if I notice symptoms. It keeps the ice tasting clean and the machine from working overtime — honestly, a little preventative care saves a lot of headaches later, and the cubes just taste better at game night.
