Question about Maytag MDB7100AWB Dishwasher

Dishwasher loud in beginning cycle and drains early

I have a Maytag Dishwasher MDBTT50AWW built in. Product was not listed below and would not let me proceed so I picked one that did not match so I could proceed. It's less than 1 yr old and was making a very loud noise in the 1st cycle. The guy who came out said it had to do with the water draining out (even when you have the door open in the middle of the cycle. We checked the hose and it is high enough but the water still drains out. The water goes down to the basement sink right below. Is the problem the water drainage or are there 2 different problems? The loud noise occured every single time except when he was here and now that we know it drains and may not be cleaning well we do not use it. What do you think is going on?

    Ok I listened to the entire cycle and the loud noise happens in the wash or rinse cycles only as it swishes water around it intermittently has a loud hum (like a race car zooming by). I checked the cycles as well, once and the water is still remains in there, too.

    Could it be the motor and maybe the water that comes out just does so if you leave the door open?

Sounds like you have 2 problems however generally speaking (most makes) of dishwashers go into drain mode when there is a fault elsewhere, however is this set up properly, is the waste pipe end high enough to allow the water to actually fill up (only about 30cms of water aprox)so it doesn't flow straight though to the waste. the noise could just be an empty pump, it runs dry after a while, and makes a screeching noise eventually? check installation pictures to see if its set up right, you may have also a leak somewhere check all other connections and pipes

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.

    Won't drain completely. leaves just enough water that you can feel it with your fingertips. no clogs in the lines. could it be the drain pump or something else. same problem occurs on all cycles.


    The most common cause for the problem is a defective pressure switch. The pressure switch is used by electronic control to detect water level and stop the drain pump. If the switch is defective, the pump may stop too early.

    See full troubleshooting here: My washing machine does not drain.


    Dishwasher is making a loud grinding noise when it's started. Doesn't matter the cycle choice; the cycle starts as normal then once started up starts making a sort of grinding noise as the water is...

    the only thing that can make that kind of noise is a broken/damaged pump/motor.
    below is a manual for part discription & a vid' showing how to carry out a repair.
    however if you are not "handy", you're gonna have to pay for a repair service.

    Is the water filling up and then draining out? Mine did this and a part was broken inside the unit. The part was five dollars and called a lifter. I fixed it myself.

    At the beginning of the cycle the dishwasher is attempting to pump out any residue water in the waste pipe and sump. It could be that the motor is sticking but you would probably also suffer from it not draining properly.
    It may just be noisy pump. I have a similar model and it is also quite noisy but nothing extraordinary.
    When the dishwasher is pumping out at the end of the washing cycle it may be quieter when there is water in the pump/pipes but then gets noisy as it 'pumps air'.

    Maytag dishwasher mdb9600awb - loud pump

    This has happened a few times to me as well.(VERY VERY LOUD NOISE AT THE BOTTOM)I have the same model It did stop.I did a little reading and came to the conclusion that it was the built in food disposer chopping blades were chopping up something like a cherry pit or peach pit and once an end of a wooden spoon that dropped down.If you look at your USE and care Guide on page 12 under trouble shooting "Dishwasher seems noisy"..I went through the same thing taking things apart.Its got to be it. Mine is 2 1/2 years as well. Hope this helps. [email protected]

    Cleaning out dishwasher

    Hi I checked the manual on line. Here's what it said.

    Dishwasher has an odor

    Run dishes being held in the dishwasher through a Rinse Only cycle.
    • Many dishwashers have a “new” smell when first installed. This will dissipate with use.
    • Dishwasher may not be draining properly. (See “Dishwasher Will Not Drain” section.)
    • For a strong odor, place baking soda in both sides of the detergent cup. Select Light
    Wash cycle and allow the water to circulate for about 10 minutes. Interrupt the cycle
    by unlatching the door and let it stand overnight. Restart the dishwasher by latching
    the door and allow it to complete the cycle. Another alternative is to use a dishwasher
    cleaning product such as Jet-Dry Dishwasher Cleaner*.

    Good Luck
