Answer to "How doI fix my inoperative Keurig Platinum?"Descaling with white vinegar is the best thing you can do for your Keurig Coffee Maker. Empty the reservoir of all water and fill it with white vinegar. Run the machine to ingest all of the vinegar in the reservoir. Half fill the reservoir with vinegar and run that through. Unplug and Let the machine sit overnight. Plug it back in in the morning and run the machine with some vinegar in the reservoir. Did the problem go away or did the machine function improve? If the machine functioned well then flush the machine with water a few times to eliminate the vinegar, this may take two or more reservoirs of water. IF it improved but is still not quite right, then let it sit again for a few more hours to an evening to see if that helps. If the problem is still there then the machine may be done.
