Newer Maytag dishwasher smells really bad inside


This problem can normally be fixed very simply and you can do it yourself.
1. There is a flexible drain line that goes from dishwasher to the sink drain line or garbage disposer.
2 You will find this flexible drain underneath the kitchen sink.
3. Make sure that the flexible dishwasher drain line goes up above the sinks lower portion of the sink basin and then comes back down into the sinks drain line or grabage disposer. The dishwasher flexible drain line must go above the bottom of sink basin like an upside down u shape, it will act as a upside down p-trap that you see under the sink in the sink drainline.
4. Once you have the flexible dishwasher drain line in this configuration (upside down U shape or p-trap) it will prevent air from leaking out of the dishwasher as the smell you are smelling is coming from the drian line.
5. You should also look inside the bottom of dishwasherr to make sure the drain screen is not clogged up.

Top sprayer is not cleaning dishes. No water is coming out on the dishes.


There may be one of two problems here and you're going to have to stick your head inside the dishwasher to solve either of them by yourself. First, in the back of the washer is a tube that goes up to the top shelf. The sprayer tube fits OVER the mouth of the other tube and then carries the water to the arm. Sometimes the support brackets for this tube become dislodged and the sprayer tube just droops but doesn't connect with the water tube. Check this first and reattach the brackets.
If this is not the problem, you might have to remove the sprayer arm (should be a screw or bolt under the arm) and flush it at the sink. There may also be pieces of paper or fragments of bone or fruit and vegetable peels stuck in the spray openings. If these won't slush out, you'll need to remove them with tweezers.
I hope this helps. It always works for me. If I have helpee, please come back and rate my suggestion!

ASKO D1776. Water in drain pan. Were does it leak from?


your connection to the sink might be your problem.. The hose from the dishwasher should be connected to a drain line or garbage disposal under the sink, If the drain line from the dishwasher goes straight down to the dishwasher thats your problem! The drain line connected under the sink should go up first then down to the dishwasher, you can fix this with a tie-tie or some tape, just raaise the drain hose and tape to one of the inlet lines to the sink, hot or cold side. Good luck

My dishwasher air flow leak why


I will guess you are talking about the air gap that is mounted on the sink top. A simple fix is to attach an extra piece of hose/pipe/tube between the sink mount and the 'upside-down y' shaped connection. This will give you an additional buffer between your sink and the splashing water flowing from 1 side of the 'y' to the other. Any number of tubes will do the trick. Just make sure that your connections are secure. Good luck

My dishwasher is apart (bottom and all tubes, pump looking things) but I'm having trouble remembering where all the tubes connect to. There are three wide diameter tubes (short, medium and long) and two...


you have one tube from pump to agitator, one to the sink and one coming into the washer for fresh water. If you are wondering about the supply tubes into the tank from the pump, the pressure is the same for all hoses.

Foul odor coming from kitchen sink/dishwasher area????


Hi Jenny - I had a terrible smell coming from under my sink, and I too thought it was a dishwasher/garbage disposal drainage issue. I used vinegar, baking soda, bleach and hot water on a daily basis. When I cut out the wallboard from under the sink and the smell got even worse, however, there was no sign of any water leaks or evidence of a dead animals. Come to find out, when I had a "friend" cut out a pass through from my kitchen (above the sink) into the den, he cut the pvc exhaust pipe and didn't re-route it nor cap allowing the fumes to escape outside via the attic. Thus, the fumes had no place to go other than down. The smell confused me because I thought it was rotten food or most likely a dead mouse trapped between the wall. The smell was actually causing me to get headaches. It's been almost 24 hours that this was repaired and I already can "smell" the difference. I hope this helps! Good luck.

Leaking from rear in cabinet


If your dishwasher leaks, check these:
Main tub seal Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

  • Lower rack


  • Spray arm


  • Spray arm support


  • Wash/drain impellers


Then pry the seal out of its housing and replace it.

Door gasket or seal Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak. 

Water-inlet valve The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

Should the drain tube be looped or can it be pulled down for extra length


If the drain line goes into an air-gap on the top of your sink than it can be pulled down. If it goes directly into your garbage disposal then it really should be looped a bit higher than the bottom of your sink incase your sink gets stopped up the water will not flood back into the dishwasher. Some models come with a "check valve" on the end of the drain line (it's plastic and is about 2" long) these prevent water from draining back into machine and potentially flooding your nice floors.

Dishwasher drains into sink


As background, the dirty water typically goes from the dishwasher to a small tube within a tube, and that goes to the disposal. This ensures that your dishwasher does not back up in the event of a clog.

The problem is likely that the tube that links the thing you see next to your faucet to the disposal is either totally or, more likely, partially blocked.

I recommend taking the entire flex pipe off and inspecting. In my case it was about 80% blocked, so a simple test whereby water was pored down failed to show the issue.

Once I took it apart and gave the tube a plumbing version of an angioplasty all was well.
