1. Remove all ice and drain water pan by removing drain cap. 2. Disconnect waterline and unplug ice maker 3. Set icemaker on a work bench unless you like working on your knees, head down. 4. Remove flip out chute and ice scoop bracket. 5. Remove water pan by removing thumb screws 6. Remove single 1/4" head cap screw that holds plastic cover over pump. 7. Remove discharge hose from pump. Pull clear plastic 1/8" diameter water supply line from notch in left edge of pump base. 8. Remove three cap screws holding pump. Two are visible. The third one is behind the pump and requires an 8" extension on the socket. 9. After the three screws are removed the pump drops down. The electric connection must be unplugged. Pinch the tabs on either side to release the plug. 10. Reverse procedure to install new pump. Unless you have really small hands or love being frustrated, don't bother to reinstall the third screw that is behind the pump. The pump stays in place just fine without that screw. 11. After reinstalling the icemaker, clean thoroughly by washing all inside surfaces with a strong bleach solution. 12. Run a cleaning cycle with one quart of strong bleach solution in the water tray. At the conclusion of the cleaning cycle, drain the water tray. Place unit into service. DON'T FORGET TO CLEAN REGULARLY. If the water supply is not chlorinated molds and algae will develop in recirculation hose.
In pre-replacement of the circulation pump, i had read a story about how to make sure you cover the drain hole to prevent hardware from falling down it. Well I followed the instructions in doing so by covering the hole with a paper towel. After removing the pump i noticed some build up behind it. So like any other person i cleaned it up, and i just happened to use the paper towel covering the hole. Im sure you know what im going to tell you next. When replacing the pump i dropped a screw and yes down the drain it went. After a few laughs between my boss and I, I had to share this. When you block the drain with something leave it THERE until the job is done.
I removed the cutter cover in the front of the ice maker (3 screws), than removed the circulating pump cover (1 screw). Remove the drain tube from the cover before removing the cover from the icemanker. The drain tube is removed by pulling straight down and twisting. Remove the circulating pump, utilizing the 4 inch extension (3 screws). Reinstalled all in reverse.
Note: install a plug in the drain hole in the bottom of the ice maker (paper towel etc). I dropped a screw on the installation and it fell in the drain hole. It did not impede the drain flow. It has now found a new home.
