I understand that your Frigidaire dishwasher is making a grinding noise. Typically that noise could be a faulty motor/pump. I have included a link to your manaul. If that does not help I would recommend having a technician out to your home to properly diagnose and repair your appliance. Best of luck. -Matt Frigidaire Manual Search Results
The LG does suffer from "poor quality" motor that causes this type of noise. The main motor and pump assembly is common to give this type of problem. The pump seal leaks a small amount of water that gets onto the front bearing and causes a "grinding = humming" noise. This can be easly replaced once you have the bottom off and dishwasher on its door. The motoe has 1 screw in the back holding the motor to the bottom and two rubber seals for the water pump in/out into the washer. Just pull and move motor and pump assmbly and it comes free. Replace with a new motor and pump assembly...
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.
it appears ur wash motor is not running.try this-start the unit and let it run for 2 min( this is the water fill period) and after 2 mins u should hear motor running and water splashing sound.u can even open the door and look for water falling from the spray arms.but after 2 mins if u hear only a humming sound and no water splash sound then motor is bad and needs to be chgd.drain motor is seperate for draining the water.
Most likely the motor/pump assembly is worn out and grinding. If the machine is less than five years old it is under warranty. If over five years old, the repair part alone is about $150 not including labor.
Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!
Motors for tall tub whorlpools are over two hundred dollars. If its less than a year then its under warranty. You did not indicate model. If you can get back to me I'll look more in to seeing if it is feasable to repair or replace.
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.
