Loud humming noise when dishwasher is filling up with water

\015 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\015\012\015\012Thanks!\015\012\015\012Have a GREAT day! :o)\015

Answers :

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-

When the water should be filling or rinsing the machine is making a horrible, loud, noise and no water is coming out. The solutions I looked at for no water don't mention this noise - they mention a slight hum. This noise is as loud as a TV turned up almost all the way! This happened during a cycle - the wash ran fine and it got to the rinse and started this.


Hi,If the noise lasts beyond 2 minutes at a time (which it sounds like it does) then you have a motor problem. I am suspecting that the main seal has leaked onto the motor and is causing water to get into the motor. ... Maytag 24 in. MDB4100 Built-in Dishwasher

Hum in Kitchen Aid Dishwasher Model 8531529. Stated last night. No hum when filling or draining - only during the wash cycle.

My Kenmore Elite dishwasher (model 665.17462300) is not spraying the water from the basin in the bottom up through the rest of the dishwasher. The basin fills with water, then just makes a humming noise and appears to splash a little of the water around the very bottom of the dishwasher. When we cancel the cycle, it does drain out the water from the basin. I cleaned all the gunk and debris out of the basin in the bottom, but it didn't make any difference.

Kenmore dishwasher has loud noise during fill. If you let it go, the washer fills. Once filled, noise stops and wash cycle continues. Sounds like plumbing does when there is air in the pipes. Not a grinding sound. Very deep pitch. Stops when the washer fills with water.


This isn't a solution but rather a comment, if the problem is happening only during the fill, then it could be the water inlet valve. Perhaps there is a soliniod going in the valve, watch to see if the fill cycle starts to dimminish over time. Does t ... Kenmore Dishwashers

I have an LG 1415M dishwasher and it is making an extremely loud noise. It's that loud when it gets to a certain part of the cycle that it is deafening. It starts to fill with water and then I presume when it starts to wash it makes this grinding loud noise. We have cleaned the filters as recommended in manual.

I have the Kitchen aid KUDS01DL dishwasher. It was working fine until last week. When starting a cycle, the washer fills with water. Once filled, the motor makes a humming noise and does not circulate the water. I end up stopping the cycle and the discharge pump empties the water. I took apart and cleaned the basin this morning. I did find some random garbage but it did not seem blocked. Do you have any ideas?

I have a Bosch SHU43C05UC diswasher. Last night, I put it on before going to bed as usual. I was awakened a couple of hours later to a loud grinding sound (like a pump being run dry), and found the noise coming from the dishwasher. The display read "0" time remaining, so I opened the door and the dishes seemed clean, so I left it shut off. Tonight I have been trying to troubleshoot the problem. The dishwasher will turn on, but it will not seem to fill with water. I have verified that the
