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.
