KBUIT4855E (05) Thermador Refrigerator - Overview

It was really easy. Took off grill at bottom of refrigerator, turned existing filter to get it out and then inserted the new one.

Just turn old filter counterclockwise, pulli it out, insert the new filter from "Part Select" clockwise and WALLLA!!!!...we have fresh clean water.That easy a caveman can do it.

The first step was to go to PartSelect.com to find where the filter is located because that is not revealed in Whirlpool's Guide. This refrigerator came with the home I had just puchased so Iwas unfamiliar with the filter replacement. Th filter is on the grill at the bottom of the refrigerator. I followed the instructions helpfully pri ... Read more nted on the replacement cartridge box which arrived in less than the 3-5 days acknowledged on my order.

Turn the filter handle 1/4 turn counterclockwise. Don't be timid. It was very tight (probably had not been replaced ever). Remove the filter from the handle that protrudes through the grill at the bottom of the front of the refrigerator.

Insert the new cartridge into the filter handle insert snugly until it goes no further and turn 1/4 clockwise.

The instructions on the replacement cartridge tell you to run the water for 5 minutes to remove air and sediment from the system. DO NOT skip this step. I was. I discovered a large amount of sediment after even three minutes of flushing. A 5-gallon pale will help. And don't forget to turn off the ice maker while you are flushing. Otherwise you will end up with ice cubes everywhere as you try to position the bucket under the water dispenser.
