Re: Kenmore quiet guard 4 dishwasher, is making a humming...
Generally, the filters are removable. You'll need your manual. Nothing can get into the motor...but they can get into the pump. Remove all the racks, get in there and find the item...likely a small bone or toothpick or that plastic bread closer.

have you ever seen green led "Clean" light flashing? before or about the same time the buzzing sound started? and if so that would indicate that the control senses a fault in the temperature rise during the heating cycle and that the electronic control could be reset by initiating a service diagnostic cycle.(which is what you were trying to do) pls reread your manual there are times during that sequence that some buttons have to be pushed at the same time and within a certain amount of time..possible that your machine also has a bad timer which would give you a buzzing noise..if thats the case I would recommend replacing the cpu or control board..or the machin all together..The Kenmore Ultra Wash Quiet Guard name is sears but whirpool has the contract to produce all "kenmore products.hope that helps.
I have a very similar dishwasher, with a very similar problem. I fixed it by removing debris from the water evacuator pump located towards the front of the bottom of the machine (the last motor before the drain hose. In my case, grape stems had clogged it up. Once emptied, it purrs once again. NOTE: don't disassemble the motor, just flush it out, there is an o-ring gasket that is a bear to re-install.
Yes the wash arm can be removed to get to the sump area. Take the model number for your dishwasher and enter it into a site like partselect.com. There you can get a blown up diagram of the components that need to be removed to get to the cause of the grind noise. Usually a seed or some other hard object has found its way down there.
I have a Quiet Guard 4. Same problem so will describe my solution.
1. Remove bottom basket. Remove top basket.
2. Remove bottom washing arm. Unscrew (Gently but firmly) the centre post. Lift arm assembly up and out.
3. Remove overhead conduit. One screw at back, one at top (Philips #2 bit). Rotate whole assembly 45 deg right (Clockwise) and lift off of centre post.
4. Remove centre post (Pull straight up). Remove 4 screws (Star T-20 bit). Lift whole assembly out. Pop off screen and clean.
5. Remove cap over cutter/chopper. There is a single screw at front left (under assembly removed in 4). Remove screw (Star T-15 bit) and cap (Needs some wiggling to free it up). Remove cutter and filter. It is on a spring loaded pin. Pull the cutter blade foreward and then the filter disc straight up. Clean thoroughly as it may be the cause of your problems.
Reassimble. Good luck!
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.
