A:Answer Hi Frank, for scratches, we recommend using a stainless steel cleaner. We recommend the Affresh Brand and here is the link to that product: https://bit.ly/3vjVimg
The Filter Reset procedure is on page 18 of the Owner's Manual and reads as follows:
RESET FILTER — Touch MAX COOL and MAX ICE together for 3 seconds to reset the water filter. The display will do a 3-second countdown, then flash the icon and play a tone. We hope this helps. Please don't hesitate to reach out to us directly if you have any further questions! KitchenAid 800-422-1230 M-F 8 AM to 6 PM ET
