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?

Re: Dishwasher loud in beginning cycle and drains early
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

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
Listen for the sound of water filling and draining throughout the washcycle. These sounds are normal and do not indicate an issue.
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
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.
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
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 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.
When you say you have checked for blockages, have you taken things apart down to the impeller? If not, recommend you look at this diagram to help get to that point looking for stuff that is broke or blocked.
If that does not fix it, post back here and we will look at the motor parts 'n stuff.
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'.
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]
