SOURCE: 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..

SOURCE: My dishwasher is making a humming sound and does not rinse?

A humming sound can be a failing wash motor (that drives the water pump) or it can be as simple as a blockage in the the pump area beneath the lower spray arm, under the filter.
Remove the spray arm and the filter top (screws will need to be removed)
Use a flashlight and inspect all over the sump area for debris that is blocking/jamming the impeller area. Reasemble and test with a short cycle.
If the dishwasher continues to make the same humming, it is time to replace the wash pump.
Good Luck! Post back here if you would like more guidance.

SOURCE: my Bosch dishwasher (shu30) sticks in the rinse

Not sure why you would want to remove the panel? When this problem occurs First try putting in diagnostic mode and going thru the cycles. Anyway the tech sheet will be located behind the panel this will walk you thru putting in diagnostic mode.
There is a series of 4 screws that hold the top portion on. These are located on the inside of the door and require a torx bit to remove. Remove the screws and then lift up and out on the cover to remove. There is not a lot of wire there so I usuall remove the lower panel also,same procedure just remove the screws and slide down slightly to remove this panel. You will have to plastic pcs that slip over the hinges at the bottom and these may fall off when removing the panel. To reassemble put lower panel on first and leave the top two screws out until the control portion is installed then put in the rest of the screws.

Loud humming just started during wash cycle


Humming can be simply due to a mechanical vibration when the wash pump is running. Alternatively it could be the sound of the detergent door solenoid which might be stuck.
Will need make and model number of dishwasher to give further advise. Does the dishwasher complete the cycle and drain out the water?

My dishwasher is just 6 months old and started making a humming sound while washing in th wash cycle.


If you hear unusual noises during dishwasher operation, check to see if a dish or cup is loose and being knocked around during the wash cycle. If you hear grinding, grating, crunching or a buzzing sound, chances are a hard object has gone into the wash module. Once the object is ground up, the noises should cease.

Bosch SHX4AP05UC Very LOUD!


This doesn't add up to what other owners say. Have yo contacted Bosch? Also, your output line may be entering your drain system in the wrong place causing the noise for that issue. Good luck. I am looking at the same machine for purchase......

GU1500XTL loud humming sound during the cycle, getting louder


The run capacitor on the main wash motor needs replacing. Eventually it will just hum and overheat instead of rotating, so better replace it now before it overheats.

I doubt you can acces it easily yourself, as it may be away from the motor, and have to be tracked down.
