Melissa, is a trick of the camera or is your heating element beginning to split on the right side? |

Take out the 10 smaller screws around the filter and then pry off the plastic frame along with what is left of the filter. This part is NLA and was never available separately anyway, but you can get a new one from another KA DW.
Other reasons why these DWs wash poorly in the top rack are a lack of water entering the machine, 98% of the time you need to replace the inlet valve to solve this. Also check the rubber feed tube for large holes in the bottom, a small 1/8" hole is normal so it will drain. Other common problem is a bad drain check valve, it is NLA but you can put a new GE DW CV rubber thing inside by just unscrewing your old one. John L. |

Hi , it is normal to see some small amount of stuff under the filter screen, but do be sure the little back-wash holes on the bottom of the wash-arm are all clear.
Water temps for KD-21 DWs, you generally would not want to go over 160F and 120 -140 is much better. The hotter the water the faster most parts that are in contact with the water will deteriorate and fail.
If the DW pauses for more than about two minutes to heat water the incoming water is not too hot and if you feel that the water is hot enough there is no harm in turning the dial past this point. The delay thromostat can easily be bypassed if you do not want this feature, and you can also disconnect the water heating element if you wish.
