Re: load crunching noise

The motor has a 2 to 5 year warranty so if that's what the repair guy says I would go ahead and have it repaired. The noise can come from the pump, impellers or the motor. But if he's sure that's where it's coming from have it fixed by the repair service under warranty.

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.

    Our Frigidaire Ultra Quiet II dishwasher loud buzzing noise- wash

    No longer "ultra quiet" huh?

    A sound during certain cycles indicates a broken part. By the information provided sounds like a pump may be the problem. You may need to contact a service tech about this issue. If the appliance still under warranty, the service should be provided for free.

    Every time when you hear noises (other than the normal ones) in the appliance, it indicates there is something wrong and it will worsen over time, so as soon you hear something is not ok, get assistance.

    The dishwasher works very loudly.It cleans the dishes very well, just the noise is extremely loud.


    Though Noise depends on the model and make of the machine, still you can use the below methods to minimize the noise :-

    1. Ensure the dishwasher is level. An unleveled machine can cause unwanted vibration noise in addition to dish rattling. Most appliances have leveling feet that adjust to ensure that the appliance is level. Ensure the machine is level. If you can't access the feet, call a professional.
    2. Install insulation around the dishwasher. A sound-absorbing foam can diminish dishwasher noise level. Unless you are familiar with how to remove or install dishwashers, have a professional perform this task.
    3. Load dishes securely. One sure fire way to cut down on dishwasher noise is to load the dishes properly. Cups, saucers and other items that aren't properly placed in the dishwasher can toss about by the jet streams of water. Put small items in a dishwasher approved, screened container to prevent them from getting caught in the dishwasher's cleaning mechanisms.
    4. Purchase a quiet dishwasher. Some manufacturers make dishwashers with built-in noise reduction features. Research and read reviews for each to determine which one works best in your situation. Magazines like "Consumer Reports" provide unbiased reviews that can be helpful.
    Hope i helped you.

    Thanks for using ' Fixya ' and have a nice day!!

    Kitchenaid Whisper Quiet + dishwasher making loud humming noise

    Very likely pump motor shaft seal leaks water into bearing casing buildup of rust and consequently noise. I just replaced $112 worth of pump assy and it's back to normal. I would also buy repair manual for $10 on-line to be sure how to disassemble the sump to get to the pump.

    Kenmore elite dishwasher noise

    I had the same problem where rubber gasket that seals the motor bearings leaked water into the bearing and rusted out the bearing.

    I scrapped the motor into every little pieces and extracted the bearing and just replace it. Now it is quiet as a mouse.

    You need a bearing puller to get the bearing out for about $20 and the bearing is $6.
    During the repair i slightly bent the shaft and i didn't straightened it properly so it wobbles a bit. But it works and if really quiet.
