Loud humming noise when dishwasher is filling up with water

I have a Bosch Model #SHE46C06UC/43 Dishwasher. Dishwasher used to be quiet during the entire wash cycle NOW it makes a loud humming sound when the dishwasher first starts up and then it does cycles of humming between the washing cycles. It is quiet during the actual wash cycle though. The dishwasher cleans the dishes just fine....it's just the noise that is annoying. What could this noise be? I have called the local service center(s) in our area, that will service Bosch appliances. They want $180.00 just to walk into my house. Please advise

Thanks!

Have a GREAT day! :o)

    I have the same problem--a high-pitched humming noise when the dishwasher is filling. Otherwise normal when cleaning. Did you ever solve your problem? I'd like to know what it was.

    Thanks!

    Could the buzzing be from the water valve?

    If so, you can go to the SearsPartsDirect website and locate the valve, and order it, or you can do the same from other repair websites as well.

    Reply back what you find or if you have more questions.

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..

It is probably the seal on your dish washer door-- Bosch is know for being a quiet operating washer- try pushing on the door during the wash cycle and see if the humming quiets- If so- all you need to is replace the seal on your door-

Why is my whirlpool dishwasher making a loud noise during drain, wash and rinse cycles?


They can be complicated to re-assemble. Best solution is to video the procedure (if you have a video camera) during disassembly and make notes and diagrams to orient things properly and make sure the correct screws go back where they shoud. Takes more time, but you'll be glad you did, it will save you a lot of aggrevation in the long run.

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?

Bosch dishwasher noisy vibration


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!

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.

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.

Bosch dishwasher timer freezing


There is a recall on the control board of many of these models, butyour problem is likely not related. It sounds like a plugged drain system or a possible bad drain pump. That's why you are hearing the pump running constantly. I have written a guide to help. It is here. Thanks!

Loud Humming Noise


You're describing vague, conflicting information. At first glance, I would think you have something stuck in the pump. But then it would be there in the rinse-only cycle also.
The anti-bacterial mode heats the water up to about 180F. This kills bacteria, and it also speeds up the action of the detergent. It could be dissolving whatever is in there.
The humming noise wasn't there in the rinse mode... The heater isn't on in the rinse mode - everything else is. But I've NEVER heard a heating element hum.

Cleaning the filter:
The filter is in the back in the bottom right. It's cover is held on by two 1/4 in screws. Under that is a large grate, and I sometimes find stuff clogging the screen (underwater, toward the center of the machine.) I'd start by looking there.

Good luck!
