Our Frigidaire FFBD2403LW dishwasher most often makes a humming noise (instead of the usual washing noise) part way through the wash cycle when using the normal cycle setting. It seems like water isn't being sprayed, but possibly only on the bottom rack. When we use the pots & pans setting, the entire cycle seems to work fine. Ideas?
Hello ddux97 - Often this occurs because either not enough water is being pumped to the spray arm or in other words the full flow of water is not making it to the upper spray arm. Will the spray arm rotate freely? If it does not, then you might have to remove or replace the spray arm assemblies since it is possibly damaged. Confirm that the drain hose is strapped up properly under the sink to prevent the water from siphoning out during the cycle. If issue persists, I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully.

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

It's noisy
If your dishwasher seems noisy, check these:
Water-inlet valve
Motor
Heater fan
Pump
Water-inlet valve
An aging water-inlet valve can sometimes fail slowly, rather than all at once. It can shudder on and off rapidly, causing the incoming water lines to shake, rumble, and rattle--sometimes violently. If yours is doing this, replace the inlet valve.
Motor
If it's the motor that's noisy, either of these may be the "culprit:"
Heater fan
If the heater fan bearings are rusted or worn, they may squeal, or scrape loudly during the drying cycle. If this is the problem, replace the fan motor. Alternatively, the fan blade may be loose. If so, you need to replace it.
Pump
Small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher.
To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller--a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris.

HI,
The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary . If the motor gear is broken, replace the sump and motor assembly . Remove any debris from the sump area in the process.
You don't have to shut the power off to the dishwasher because the door will be open, but if you feel more comfortable, do so.
thanks,

most times i have found a foriegn object in the pump. sometimes the machine will clear it itself but other times you have to take the pump apart. it is not too difficult but you will need a size T15 and T20 Torx aka (star) bit to get it apart. Just keep taking out screws until the filter flowplate lifts off.

I have the same problem with my dishwasher. If you remove the kick plate while it is running, There is an electric motor underneath. If you push up and pull forward on the electric motor, the noise will stop. I used a block to prop it up and the noise stopped. You may want to try it.
Good Morning Larry Looney, thank you for your post!
I understand that your Frigidaire frontload washer is making a humming noise while in spin cycle. This could be a potential problem with your motor or drum bearing. In order to find the proper cause of the humming noise I would highly recommend having a professional technician come out to your home for diagnosis and repair. This will help to avoid any unnecessary part purchases as well as any future issues. -Matt
