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.

My ge whdsr 316G washer is extremely noisy when agitating

Most likely your transmission is about to fail, Run it into the ground if you can stand the noise. Prepare for transmission replacement.
Online applaince parts are usually very helpful. Parts probably $200. plus. If you are tool literate, you may be able to do it. If not I don't recommend. You might want to consider a lightly used replacement, or New.

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.

    It runs EXTREMELY loud

    Hello, W/D here.
    The problem is most likely in the motor/pump assembly, and they're sold as a unit. Prices range from about $130 to $220 or so. You can look up your model on this site for comparison shopping, if you decide to look somewhere else.
    If you are handy with tools, this is a job that is intricate, but doable. I have made a similar replacement on a KitchenAid dishwasher, where the noise started out low and increased over a period of several months to sound, as you said, EXTREMELY LOUD. Six months later, the noise started again, and increased again. I changed out the machine after that.
    It might be worthwhile to get a local tech to give it a listen, and a free estimate, and decide whether to repair or replace it.
    Best regards, --W/D--

    My whirlpool dishwasher is supposed to be really quiet, and it was for about 2 years, the past 6 mos it is really, really loud. What happened? Does it need a new motor?

    Hi, You don't necessarily need a motor, a couple of things could be to blame. It may be debris in the sump well or the chopper assemblies on those can become worn and break loose from the motor. Either of these things can certainly make your normally quiet dishwasher very loud. If you feel capable pull the sump cover off and inspecf it ( youtube has great "how to" video's ) or if you don't feel comfortable doing this, it may justify paying a service person to check, but I wouldn't be too quick to right it off. Hope this was helpful. Thank you for visiting "fixya" and good luck moving forward. Macmarkus :)

    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.
