Hi.

First of all have you noticed whether the noise happens through the wash cycle or when it drains the water?
If its the former then it will be in your wash motor, the later in your drain pump.

Have you noticed whether a drinking glass was cracked or broken when you emptied your dishwasher?? if so it could have found its way into the wash motor or drain pump.

If the noise is high pitched ( like a saw mill) it is most liokely to be a wash motor bearing thats failed. If so you are looking at a new circulation (wash) motor.

Hope this helps

I have a year old kitchen aid dishwasher and during fill cycle it makes a thumping noise. The dishwasher every 5 or 10 seconds shuts off fill cycle then turns back on which I think is what's causing...


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.

When washer is started make loud grinding noise


Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

Reply back and we can you more.

Makes growling noises throughout the cycle.


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.

Dishwasher is 1.5 years old and makes loud noise and does not get dishes clean


HI. the wash impeller is damaged. this will cause much noise during the wash and it will affect the nature of the wash dramatically. this impeller is attached to the circulation motor under the sump. it should be replaced asap, if possible.

Kitchenaid Whisper Quiet + dishwasher making loud humming noise


Very likely pump motor shaft seal leaks water into bearing casing buildup of rust and consequently noise. I just replaced $112 worth of pump assy and it's back to normal. I would also buy repair manual for $10 on-line to be sure how to disassemble the sump to get to the pump.

Whirlpool Dishwasher suddenly making a grinding noise...


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.
