A:AnswerHello Question, we can only advise on what the installation guide states. We are attaching a link for your convenience. https://www.whirlpool.com/content/dam/global/documents/201705/InstallationInstructions-W11084412-RevA.pdf
A:AnswerHi Jeff, the WMH32519HT does not come with any filler kits, but we do have accessory Filler Panel Kits. This model is so new we do not have access to the documentation yet, but the Installation Guide will list the proper part number, it may even be the 8171338 Biscuit. But pleases refer to the installation Instructions to verify
A:AnswerHI Olson, the outlet must be above the WMH32519HV normally in a cabinet. If it is within its 30" width and close to the center, the cord will be long enough. Refer to the drawing on page 3 of the Installation Instructions and you will see where the recommended location is. It can be on the left side of the upper cabinet.
A:AnswerOnce a month just fill your sink with hot soapy water and let the filter sit in it for a while and rinse off. It will last forever if you do that.
