Can I purchase just an impeller assembly for motor number 154700101 or do I have to buy the whole thing.
Unfortunately the manufacturer does not provide the impeller as a separate component and you would need to replace the complete motor assembly.
dishwasher has slow leak coming from the righthand portion of the motor assembly that is white plastic. Part #AP5272221. This slow drip runs down the side of the plate that is screwed into the bottom of the dishwasher with 2 star screws. Could this be seals, the housing, etc. there appears to be a small hole in the opening in the white plastic area, is this normal ( like a pressure releif ? ). Dishwasher runs find and drains fine, just the agrivating leak that needs to be wiped up each time it is used.
Answer Doug, If water is leaking from the hole in the pump, that would indicate the motor shaft seal has failed, the is usually referred to as a "weep hole". If the water is leaking from around the black portion of the motor or bracket, you'll need to check or replace the "O" rings and check the pump housing for cracks in the screw holes, the bracket shouldn't be an issue, but it applies pressure to the seals and secures the pump motor to the housing and forces the motor to seal to the "O" rings. Make sure the Torx screws are tight and not stripped when installed and tightenned.

my frigidaire dishwasher model FDB520RHB is only about 2 or 3 years old and it has recently gotten really loud during the wash cycle and the top sprayer arm has stopped spinning. what could be the problem?
Answer Mellissa, First thing, check and make sure the dishwasher has the proper amount of water in the tub. Start the dishwasher and let it run five(5) minutes, then unlatch the door and remove the lower rack. The water level should be approximately 1/2 way up the spray arm support 154294101(1 to 1.5 inches deep) if theres not enough water in the dishwasher, the pump will produce excessive noise and the upper spray arm cannot turn due to the lack of water and pressure. If there is not enough water, you'll need the fill valve 154637401.If the water level is in range, you'll need to remove the spray arm, filters and support and check for debris or deposits on the screens and in the sump assembly and clean it all out.
