Frigidaire dishwasher FDB1050req0 runs normal for a few minutes and then starts a loud humming noise. I think the main pump works but when it switches over to the top its making a horrible humming.
ANSWER Becky, You want to check mand make sure you have the proper amount of water in the bottom of the tub. low water level can and does make a motor run "noisy" and with a split wash system, it's even more prevalent. Check and make sure theres nothing holding the float 154767801 up causing it to open early. Start the dishwasher and let it cycle for 3 to 5 minutes, unlatch the door and remove the lower rack, The water level should be slightly above the filter 154252401 1/4 to 1/2 inch deep. If alls OK, you'll need to chrck the filters and the interior pump for deposit build up causing improper water flow and pressure. Thanks
