The sound that is coming from the dishwasher seems to be a cracking type of sound. It happens off and on throughout the wash cycle. I emptied the dishwasher and checked for any loose objects in the bottom and made sure everything was clear, then ran it empty. After several minutes into the wash cycle, the cracking noise started. I can't isolate where exactly it is coming from. I have never noticed this type of noise before. sound familiar to anyone? Any ideas?

No a noise filter is a different kettle of fish. That stops electrical interference noise from affecting your television, radios and electrical devices.
The most likely source of the hum is the start capacitor on the motor, or the motor itself.
Humming or Grinding
If your Samsung dishwasher makes noise when starting that sounds like a low hum, it's part of normal function. The motor makes this sound as it operates throughout the wash cycle. However, a dishwasher making loud humming noise or grinding sounds could mean that debris is caught in the drain pump.
am not sure.. just try this Check with a multi-meter for 115/220V on motor's tags. If you don't get this voltage measurement, your problem is not with the motor. In
case you have 115/220V on motor's tags, try first to replace its
brushes (2 carbon contacts that transfer the curent to the motor's
armature). try this good luck
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 washcycle. 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.
I would suspect there is something stuck in either your wash motor or drain pump. If the noise happens throughout the whole cycle, it's likely the wash motor, but if it only happens on start up and periodically thoughtout the cycle, it's the drain pump. The drain pumps are known however to get noiser after a few months, in which case I would have the drain pump replaced.
The most common cause of this is a loose clamp on the pump discharge hose. It could also be a cracked hose, the hose came off (again, loose clamp). Check both ends - where the hose connects to the dishwasher AND where it connects to the sink drain.
Another possible cause is a bad pump seal, although this is less common, and usually open happens when the dishwasher is pretty old.
ck the float it may be comming under the door . if water is still in tank after cycle / clean the screen in the bottom it is a lift out basket . ck for resstriction in drain line . all of thes will cause over fill and flooding . your model may have a pressure sw . sometimes food gets in the air line / remove tube and blow out .. mm
It seems that your motor on the dishwasher is going out, like mine has just done. My explanation is that it sounds like something is grinding on glass or as if a bunch of mice are making noise. Eventually, the motor will not run any more. What will happen is that the dishwasher will fill up, then make a loud humming noise, while the heating element is making the water near the heating element sizzle. Now what you have is a possible fire hazard which compounds the problem with the dishwasher. Get rid of it, take the loss and live like my grandmother used to, without having a dishwasher. That is the best advice I can give you.
