Maytag 300 Quiet Series Dishwasher

My dishwasher appears to not be draining properly. After each complete cycle there is water in the bottom of the tub. Model #MDBH965AWW My maytag quiet series 300 mdbh955aww is not cleaning my dishes! There is always dirty water left in the bottom of the washer after a cycle. I discovered that the sprayer arms are not turning on the rack, bottom, or top. It seems like there is not enough water pressure. I took the machine apart down to the motor. I didn't notice anything wrong, but I didn't know what to look for. Also, lately it has been making this horrible clicking and grinding noise. Any suggestions?
Thanks, Christine .

SOURCE: whirlpool quiet partner II top rack sprayer doesnt

The top rack spray arm doesn't work because of low water pressure from the wash motor or it's clogged with debris.
If the top spray arm looks clear of debris, remove the lower spray arm and lower feed tube to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). Remove any debris from the sump area in the process.
You don't have to shut the power off to the dishwasher because the door will be open, but if you feel more comfortable, do so.
Good luck!

SOURCE: Maytag Quiet Series 300 dishwasher, dishes come out dirty

A water softner will not make the dishes any cleaner, it just makes it so they don't have water spots on them.
If the dishes are dirty, it is most likely that the nozzles (holes) in arms may be plugged.
Also check to make sure you are getting plenty of water to dishwasher. Make sure all water valves are full turned open.

If the control panel does not work all the time, it is very likely you have either a shorted wire, or a fualty main board which is very common in newer machines.

SOURCE: Maytag Quiet Series 300 smells broken door latch and lower rack

I have had the same problem and there is a simple fix.

The problem in my case was the floating water sensor was stuck and gummed up with grease.

On the bottom of the dishwasher, in the front right corner there is a round doughnut-looking thing. This is the water level sensor. It is open on the bottom, and grease collects there.

When this happens, the air pocket is too small, and the float won't float. then the dishwasher overflows. To clean it: just reach under with your finger, and scoop out the grease.

Sometimes, after doing this, the float then gets stuck in the "up" position. When this happens, the dishwasher completely drains, and the heater element for the dishwasher is exposed, and food cooks onto it, and that is where the smell is coming from.

SOURCE: quiet partner 1 top rack does not get clean at all

Hi,

I would suspect you have debris in the pump that is causing a pressure drop so the water is not spraying well in the upper arm.

Try this procedure to clean out the sump. Let me know if it helps.

My dishwasher the maytag quiet series 300, will not respond to the start button


Find your circuit breaker for your dishwasher and turn it off for 3-5 minutes. Turn it back on, then turn on your dishwasher. If this works, after the complete cycle of your dishwasher, you have to turn it off manually by pressing "on" botton then press it 1 more time to cancel; this will turn off. The defect is, probably the moisture built up in the control board causing it to ground some of the connections. Suggestion for the manufacturer, insulate the control board to prevent absorbing moisture.

Dishwasher won't drain--Maytag Quiet Series 300


A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.

Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.

Maytag Quiet Series 300 won't drain all the way. I've checked the drain tubing and there is no blockage. Can someone help?


When you say you checked the drain hose, was top and bottom meaning did you pull out d/w. If you hadn't remove the bottom hose and check the bottom of the hose as well as outlets for the pump, clean out and run through cycle. If you had, then clean out the drain area in the tub of d/w. , should this not work, your pump is not working properly.

Foul smell coming from Maytag Quiet Series 300


Hello jscott,
It is typical nowdays for most dishwashers not to drain all water out of the bottom tub (Even where you cant see) due to siphon design and energy efficiency. Try using about a liter of vinegar and throw it on the bottom tub of the dishwasher. Let it run through a full cycle and see how that works. Has worked for me

Hi jeffwirch,

I'm Harvey the Master Plumber.

Your problem is: You have a maytag quiet series 300. When it is done with any of the cycles in leaves about 1-2 inches of water in the bottom of the dishwasher. You can manually hit the start button twice and it will go through a 2 minute cycle and pump out the water. You have cleaned the filter inside the dishwasher where it drains and have checked the hose to the disposal and it pumps out fine. It just doen't pump itself at the end of the cycle.

It sounds like a bad control board. It's in the top of the door panel. I don't recomend this repair to the average homeowner. You might consider the Repair Directory to find a repairman.

Water does not drain completely, mostly but not completely and just stays there Maytag Quiet Series 100


If the machine has a auto sensor or auto clean cycle it is supposed to keep water in the bottom. The sensor has to stay wet for it to work properly. My Maytag drains, then fills slightly to do this.

The 3 symbol on the face control panel light is on and starts flashing anytime you push any other button, and is full of water in the bottom of it. My wife says she stopped the washing cycle a couple of days ago but now it wont start back up.
