How to clean a water dispenser bottom load?

Cleaning a bottom-loading residential or office water dispenser requires a systematic sanitation process to eliminate mineral scale and bacteria buildup. First, unplug the dispenser power cord from the wall outlet and remove the empty water bottle along with the internal non-spill probe assembly. Second, drain any remaining water from the internal reservoirs using the hot and cold spigots into a bucket. Third, fill the internal reservoir with a cleaning solution composed of one gallon of warm water and one tablespoon of plain white vinegar, letting it sit for twenty minutes. Fourth, scrub internal surfaces with a soft brush and drain the solution through the spigots, then flush the system thoroughly with clean water. You can troubleshoot taste issues easily. You can verify success when flushing eliminates vinegar residue and yields clean, fresh-tasting water.
