Loud Humming Noise

Our dishwasher recently started making a loud humming noise during the wash cycle...almost sounding like the motor is being stressed. We have been using the Anti-Bacteria mode for the past couple months since the dishes were ...which seemed to help. When we ran the rinse only mode it was quiet and did not make the humming noise. Any ideas? Also could you please let me know how to clean the filter? Our model # is PDW788oJ10SS.

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!

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?

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.

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..

Dishwasher making loud humming noise


The most common cause of the hum/grinding sound, and often poor cleaning - is a blocked filter or debris stuck below that filter.
Pretty easy fix: Get a phillips screwdriver near by. Pull out the lower rack (the upper rack can come out if you pull the little gray thingeys on the front of the upper rails.)
Remove the lower spray arm -- just pull it straight up. Remove nine silver screws from the sump area that holds the filter down. Pull the filter up and out. Rinse the filter as best you can.
While the filter removed, with a flash light inspect all over the sump area - looking for stuff that should not be there and clean it out. Watch out for broken glass!
Replace the filter, screws and the spray arm. Fire it up and check your results!
Good Luck!

It seems that your motor on the dishwasher is going out, like mine has just done. My explanation is that it sounds like something is grinding on glass or as if a bunch of mice are making noise. Eventually, the motor will not run any more. What will happen is that the dishwasher will fill up, then make a loud humming noise, while the heating element is making the water near the heating element sizzle. Now what you have is a possible fire hazard which compounds the problem with the dishwasher. Get rid of it, take the loss and live like my grandmother used to, without having a dishwasher. That is the best advice I can give you.
