Remember that ice makers contain toxic refrigerant. Hand and eye protection are recommended

A medium phillips-head screwdriver is also required

unplug your countertop ice maker

place over the sink and pull out the rubber stopper from the bottom

wait for all fluid to drain

Once drained, place ice maker on its side. Remove the highlighted screws that hold the back plastic cover in place.

Then remove the black plastic cover.

remove the screws holding the top cover in place.

Don't forget the other side!

remove two screws holding the tray motor in place. Then pull the tray motor straight out. It may require a bit of force if rust is sticking it onto the tray

remove the water intake hose by pulling it straight down

uncover the electronics by unclipping the specified points

unplug the wire connecting to the right side panel

remove the screws holding the side panels in-place

unscrew the refrigerant pipes from the side panel

carefully remove both side panels

at this point, the ice tray should be freed up for removal (and cleaning)
