MODEL OVERVIEW
About this model: GE PFE28KMKES
PFE28KMKES Slate AutoFill Not Found, recognition and water-system checks.
Locate the Slate KMKES layout
PFE28KMKES is the Fingerprint Resistant Slate refrigerator in GE's PFE28K group. Its exact listing gives 27.8 cubic feet overall and 9.19 cubic feet in the freezer, with two full-width freezer baskets and two freezer LED lights. It also describes a full-width temperature-controlled drawer with its own LED lights. The linked owner manual's page nine places PFE28K in Control Style B, labeled AutoFill Models. That panel assignment agrees with Hands-Free AutoFill on the exact product page. Use the KMKES ending for capacity and finish; a nearby PFE28KELDS shares much of the control design but has a different capacity and color. The Slate storage layout deserves its own reading before interpreting a dispenser alert.
Investigate a Not Found cup message
AutoFill uses sensors to measure the vessel's height before dispensing water. The rendered instructions say that when Not Found appears, the first useful trial is a different container. Place a fairly uniform cup centrally on the recess tray without touching the paddle; compare it with the manual's recommended height and width range. Wipe the sensors carefully with a damp cloth, and do not spray cleaner directly at them. The troubleshooting table sends underfill or no-fill cases that show an error message back to this AutoFill page. A wavy rim, very wide opening or poorly positioned cup can defeat detection without any refrigeration fault. Repeat with a regular vessel before changing the temperature or ordering parts.
Separate recognition from water delivery
The manual warns that container shape, ice in the cup and splashing can change the final fill volume even when AutoFill starts normally. That is distinct from Not Found, where the sensors do not accept the container. The exact model also has a Water Filter Indicator Light. Its linked instructions place the cartridge high on the left fresh-food wall, and the troubleshooting section explains that the indicator eventually lights when replacement is due. If a suitable cup is recognized but receives little water, review the filter and supply separately from vessel detection. If the cup is not recognized at all, start with position and sensor cleanliness. This order avoids misreading a maintenance lamp as a failed AutoFill sensor.
Use the cold-storage options accurately
The PFE28KMKES listing offers a second icemaker option, not a guarantee of an installed second unit. It also specifies optional WiFi that requires module PBX23W00Y1. Its Showcase LED lighting and TwinChill evaporators are confirmed exact-product features, useful for finding food and managing the fresh-food and freezer spaces. Style B temperature controls display the selected set point when Fridge or Freezer is pressed; this is separate from the AutoFill control at the dispenser. The Slate unit's 9.19-cubic-foot freezer has two baskets, so leave access for the drawers and do not confuse their movement with a door or dispenser alarm. A genuine Not Found message still directs attention to the cup and optical area rather than storage settings.
