The dishwasher is not spraying on the top amymore any suggestions as to what is wrong? Also it is making an abnormal noise too.
Answer Kerri, The noise, and the poor washability in the upper rack, is most likely due to improper water level. Start the machine and allow it to fill and wash for 5 minutes, open the door and remove the lower rack, the water level should be approximately 1/2 way up the lower wash arm support. If the level is not that high , you'll need to replace the fill valve 154637401. If the water level is in range, you'll need to remove the lower spray arm, support and filters and check the pump impeller for clogs or damaged vanes 154245801.
Is it possible to replace the impeller without removing the wash pump and motor?
Answer Hopeful, Sorry, but no you can't. You will need to remove the motor pump assembly from the pump housing to replace the impeller. It's not that involved, and we'll send you some information.
The impeller is slipping on the motor shaft. How is the impeller supposed to be fixed to the shaft?
Answer Hello Dave. There are two flat spots on the impeller that keep it from slipping on the shaft. If it is slipping, you may need to replace the impeller 154245801. Hope this helps.
