    Dishwasher is only 2 months old, was very quiet to start, suddenly, very loud humming, buzzing noise when running.

    I have a similar model Frigidair. I suspect that the pump motor is going out. Everything else seems to work okay, although we do have to pre-wash the dishes by hand to allow the dishwasher to do a decent cleaning job. Dishwasher, my ****.

    We have a 1.5-year-old Frigidaire FDB1500LFB dishwasher. So far the computer has gone on the fritz (3 days after warranty period expired) and now it is operating at loud buzzing levels (so loud it hurts my ears if I'm next to it). Considering just replacing the stupid machine.

Try tightening the screws along the side of the door cover, it could be that the front panel is vibrating.

Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.





Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.





Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.





Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.





Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.





Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

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.

    Noisy drain pump on FDB635RF?


    Two questions: 1) Are there filters that need to be cleaned on a routine basis with the FDB635RF? and 2) What causes the scum left behind on glasses and utensils? I use a rinse aid, but doesn't seem to be helping. This is a recent problem.

    Our Frigidaire Ultra Quiet II dishwasher loud buzzing noise- wash


    No longer "ultra quiet" huh?

    A sound during certain cycles indicates a broken part. By the information provided sounds like a pump may be the problem. You may need to contact a service tech about this issue. If the appliance still under warranty, the service should be provided for free.

    Every time when you hear noises (other than the normal ones) in the appliance, it indicates there is something wrong and it will worsen over time, so as soon you hear something is not ok, get assistance.

    Loud Buzzing Sound from Dishwasher


    have you ever seen green led "Clean" light flashing? before or about the same time the buzzing sound started? and if so that would indicate that the control senses a fault in the temperature rise during the heating cycle and that the electronic control could be reset by initiating a service diagnostic cycle.(which is what you were trying to do) pls reread your manual there are times during that sequence that some buttons have to be pushed at the same time and within a certain amount of time..possible that your machine also has a bad timer which would give you a buzzing noise..if thats the case I would recommend replacing the cpu or control board..or the machin all together..The Kenmore Ultra Wash Quiet Guard name is sears but whirpool has the contract to produce all "kenmore products.hope that helps.

    Loud humming noise when dishwasher is filling up with water


    your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.

    there are two components that start before the circulation pump.(wash noise you hear)

    first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.

    the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..
