I have a Frigidaire FDB1502RGS3 Dishwasher. It use to be very quiet throughout the whole cycle. Now about half way through it becomes very noisy. I have taken off the bottom panel and noticed that if I lift up on the round hosing on the left side of the pump it wil quiet down. Suggestions?

Some dishwashers have soft food disposals. If something gets in this disposal that will not dissolve such as bone, pop corn kernels, broken glass. This will make noise throughout the cycle. Sometimes after many cycles it will grind itself away. Otherwise service would be needed if you don’t know how to get inside the pump.

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.

A solution to this problem would be to sell me your dishwasher. The law firm for which I work is looking to acquire an old unrepaired Bosch SHU 33 dishwasher for some ongoing litigation. If you (or anyone else with this model Bosch) could send me some details regarding your dishwasher, you may be able simply to buy a whole new dishwasher. My email is JFraser -at- jshlawmi.com.

Thanks!

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.

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.

It is the wah motor. contact Frigidaire for a replacement motor that has been redesigned to eliminate that noise

HI. here are the most common issues that will cause a noise during the wash.

* Check the spray arm for damage and obstructions
* Check the inlet filter screens
* Test the water inlet valve(see below for test procedure)
* Check the motor and mounts- The motor may e loose or one of the mounts may have separated form the housing. this will cause mis-alignment.
* Check the fan motor and blade
* Check the drain for obstructions


NOTE

If all checks out above, the culprit will be a cracked pump impeller. this will occur if the drive stud becomes unstable, allowing the impeller to partially separate form the motor spin drive stud. this will cause the impeller to rub or grind during the wash cycle. If this is the case, there are impeller repair kits available for purchase that will correct this issue.

Either the motor is failing to pump water or there is too much soap in the system. Add 1/4 cup veg oil and run again.

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.

dishwasher less then 2 months old was really quiet when we purchased now has a loud vibration noise when water is pumping out.
