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.
