Grinding noise while washing

SOURCE: Diswasher motor making noise during wash cycle

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

SOURCE: dishwasher does not drain

If you cannot get the diswasher to drain there is some obstruction in the drain line going to the disposal. First turn the power off to the diswasher at the breaker panel then open doors under sink and follow drain line to the disposal there you will find a hose clamp(silver) that you must loosten with a flat blade screw driver ( get a bucket under the disposal) pull the drain line loose and dump out excess water and debris inspect area going into the disosal to make shure it is not clogged up

reverse your proceedure and reconnect the drain

Before trying the dishwasher take some ice cubes and run thewater then put in disposal and turn on that should clean the disposal

try your dishwasher I forgot to mention that theri is a strainer at the bottom of you dishwasher that you can remove to be sure it is not clogged up I assume that you have aready checked that

good luck

Hi All,


I have had a Maytag Quite Series 300 for some years now and have done basttle with it on may occasions. I now consider myself somewhat of a veteran, although by no means a repair expert!


Grinding Noise: From either a clogged/blocked impeller or not enough water getting to the impeller.
For a clogged impeller, it is fairly easy to disassemble the washer to get at the impeller to remove any debris or blockages.
For not enough water it can be a number of things. First of all, you will notice that the noise lessens if you add a jug or two of extra water. This is because if the water level is too low, the pump impeller will get some air mixed with the water & this is LOUD! Now for the causes:
Float – If the float gets stuck in the wrong position (debris or water deposits), it will not fill enough.
Float Set Wrong – Seems thats some of these dishwashers have the float set a little too low to let the dishwasher perform without grinding. A few pennies attached to the float with a rubber band seems to help here. Don't go too far or you'll flood your kitchen!
Timer – Some folks have mentioned that dishwashers that fill on a timer will not fill enough in the allotted time, if the water pressure is low. While this is true, I have looked over the electrical & parts diagrams for the QS300 and I do not see a timer listed anywhere. Also, the wiring diagram appears to show that this dishwasher only uses the float to achieve the correct water volume. I could be mistaken here.
Note that in VERY hard water areas (like mine – TDS of 850 hardness or 49 Grains), the plastic fins on the cover of the impeller get very choked up with water salts and this can impede flow, leading to a low-water symptom, when in fact, there is plenty of water.


Dishes Not Cleaning:
Poor Water Flow – See above, all the above items will negatively impact dish cleaning.
Poor Q uality Detergent – After trying them all – Yes, all – Do not use cheap detergent. Buy the brand names: Cascade or Electrasol work well. I have found that by far, the little packs work the best. We found that the liquid works second best and the dry stuff really isn't up to the task at all, no matter which brand.
Spray Wands Catching – We found that our lower spray wand was catching on the bottom of lower dish tray, so I very slightly bent down the legs that the wheels mount to in order to lift the dish tray/basket a little and give the wand a little more room. This worked well.
Spray Wand Nut Too Tight – The factory seems to send the dishwasher out with the nut on the bottom spray wand tightened a little too far. Loosening this a little bit lets the bottom wand rotate much more easily.
Top Spray Wand Not Meeting Receptacle – The top spray wand is attached to a pipe that mates with a port (well, one of two ports, depending on if you have the top rack in the “Upper or “Lower” position). The pipe seems to have a tendency of missing the port. A well placed elastic band will help here. Note that on our dishwasher, by the time the first elastic band wore out, the pipe had been permanently moved to the correct position by the gentle pressure.
Tines/Dish Holders On Top Rack Falling Over – The tines (metal spikes) that hold dishes on the top rack fold down by design. Issue here is that they do it sometimes during the wash, causing the dishes to fall over and block the spray. A few well placed rubber bands help here as well.
Water Salt Buildup – If you live in a very hard water area, you can still get clean dishes from yor dishwasher. We do and we have VERY hard water. Buy a gallon of vinegar once a month. Pour this into a clean dishwasher. Turn it on so that it runs for 2 minutes to circulate the vinegar. Open the door & let stand over night. Close door & finish cycle. This will cut down significantly on the hard water salt buildup in the washer.
It's A Maytag – Sorry folks, it's true. I have learned (after purchasing the dishwasher) that Maytag has run into financial difficulty in recent years and has reduced build quality to save money. If you got suckered into buying one of these, you will very likely never buy one again. My opinion is “Do not by Maytag.”


Hope this helps someone!

SOURCE: very noisy wash cycle

most times i have found a foriegn object in the pump. sometimes the machine will clear it itself but other times you have to take the pump apart. it is not too difficult but you will need a size T15 and T20 Torx aka (star) bit to get it apart. Just keep taking out screws until the filter flowplate lifts off.

SOURCE: Dishwasher is not draining correctly in the air

Hi and welcome to Fixya, I'd suggest you start by checking the drain spout of the disposer where they ( the installer ) connected the drain hose from the dishwasher and make sure they've knocked out the plug in the spout. **Turn off the power or unplug the disposer/garberator before performing any service** If the plug is not punched out, with the aid of a long screw driver and a hammer, or a firm smack with the palm of your hand you should be able to knock out the plug. Then reach in the disposer and remove the plug you`ve just knocked out, reconnect the drain hose for your dishwasher and you should be good to go. Thank you for visiting "fixya". Please take a moment to rate the solution provided here for you. Hope that help`s. Good luck. macmarkus :)
