Re: Loud grinding noise when washer is draining

Something in the impeller housing. not usually serviceable. not sure if that unit has two pumps. you could look underneath the tub and try to determine that, and where the noise is coming from.
i am confident the issue relates to a pump unit.
good luck

Loud sounds

Many Frigidaire dishwashers come with the promise of being the "quietest dishwasher in its class," according to Frigidaire. However, a quiet dishwasher doesn't necessarily mean that the dishwasher is silent, as some noises are normal. It can take some troubleshooting at times to determine if a noise coming from the dishwasher is typical or if it indicates a larger problem Listen for the sound of water filling and draining throughout the wash cycle. These sounds are normal and do not indicate an issue.

  • 2 Pay attention to the drain motor, which operates at the beginning of each cycle. This noise should be fairly quiet and should not sound like a loud, grinding or banging sound.
  • 3 Note that the sound will change when the wash cycle moves between the lower and middle spray arms. This sound should be temporary and fairly quiet.
  • 4 Look for hard items in the dishwasher grinder or filter if a loud crunching, buzzing or grinding sound is heard. The dishwasher can typically grind up these items within one or two cycles, but the item may be lifted out and discarded to eliminate the sound.
  • 5 Remove the bottom rack and spray arms from the bottom of the dishwasher if there is a loud noise coming from the dishwasher that does not resolve itself. Look inside for the impeller, which is round and spins. Remove any debris that may be clogging up the impeller or pump.

    The dishwasher is less than 2 months old and has made a loud grinding noise from the start. I believe the noise is coming from the pump or another part from under the unit.

    Hello, Thank You for using FixYa. I will be helping you today.Make sure nothing is up against the motor! Also the drain pump on this unit can be loud.You can try to put something to help support the drain pump if it is vibrating. I would start looking at these things before calling for service.
    Thank You and please rate my answer if it was helpful..

    When washer is started make loud grinding noise

    Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

    Reply back and we can you more.

    Loud grinding noise that should go way after one complete cycle. After 3 cycles it just gets louder and louder.

    Remove the lower spray assembly and clean out the sump area.
    Probably broken glass or a loose screw got in there.

    Loud Humming noise every time we run the dishwasher

    Hi, I had this exact same problem. In my situation it turned out to be the pump that pumps out all of the used water. It was rubbing up against the floor so that every time it turned on it made a loud vibrating sound. I just reached under the washer and put a piece of rubber between it and the floor and it solved the problem.

    good luck!

    I saw this post because I am considering buying the same model you have. Other than the noise problem you have, what do you think of it?

    Dishes not coming clean

    Check to make sure that the drainline is not backed-up or obstructed. If water is draining properly, you may need to reprime your washer. It may have been turned off before being completing its cycle. To Prime, Start the dishwasher and slowly advance the timer, till you hear the water valve open and fill. Let the washer do the rest. If a loud whining noise appears and does not go away after filling, check the motor to make sure it is not locked up. If locked up. Turn washer off and attempt to turn the impellor. Once free, it should be ok

    Loud noise when unit is pumping

    Sounds like it is not getting enough water. Try adding water to it to see if the sound goes away. Start the unit at the begining of a cycle, open the door after it has started to circulate and see where the water is at. If it is low then you have a problem with the amount of water coming in, possibly the waterproof (valve) is going. If the level is good and it happens later in the cycle, it could be a drain issue. You may have to get in a tech.

    Diswasher motor making noise during wash cycle

    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.
