How hot is your water in your home? Newer dishwashers do heat the water but they still require 140 degree water coming in. Also the detergent you use can make a difference. Cascade complete costs more but continues to be the best. Also you can run a cup of vinegar in you washer without and dishes in it to clean it or you can use this stuff they sell in the store called dishwasher magic. Make sure your dishwashers filter is clean and the drain check valve is working. If the check valve is stuck dirt dishwater will flow back into the dishwasher causing dirty dishes.

Make sure you water is hot enough, manufactures reccommened 120 degrees to the dishwasher, i advise all customers to run hot water at sink til you get hot water then turn dishwasher on, also fill both compartments of sopa, also use rinse aid or jet dry, do not use gel packets. use cascade powder or liquid only.also run the unit through a clean cycle this should be done once or twice a year. letdishwasher fill with hot water. when starts to wash, open door and add 2 cups of white distiilled vinegar and close door and let it go throughas cycle. no dishes. also i reccommened dish majic cleaner sold at walmart or grocery stores. if this dont help then youw wash syatem could be bad or going bad.hope this helps you. try all these things first befor you re[lace uniy or pay to have it looked at.

What are dimensions for Maytag dishwasher Model # DWU7400AAX?

google maytag dwu7400aax dimensions for your answer less than 3 seconds.


This is just a standard size dishwasher model. Dishwashers in general are going to be standard size unless you get a portable dishwasher or a 30 inch wide dishwasher. There are very few of these models. Your size dishwasher is just 24" wide 24" deep and 34 1/2 inches tall but the height can be adjusted somewhat

My injectors not spraying eough fuel just bubbles its a 3l engine hilux

it sounds like your fuel injectors may be clogged or dirty, you can take your vehicle to a shop and ask them to clean the injectors or you can attempt to clean the fuel injector you will need a fuel injector cleaner, in order to find the dirty fuel injector you will need a fuel pressure gauge,and a fuel injector tester,both items are very cheap and can be purchased at this website www.discountbargainprices.com,

Im not getting eough water pressure out of my appiance it leaving spots and stainn on dishes i ran a cycle of clr but i still get same result

The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers and make sure that there is nothing obstructing the outlet pipe and the pump. If possible back flush through the outlet pipe and try draining the machine again before using it again.

When we open dishwasher theres standing water in the drain area and it smells bad this is after washing aload dishs look clean but inside stinks

After you run a load of dishes put 1cup of CLR or vinegar (white) and run a quick wash.no dishes,after running dishes clean out spray arm and clean strainer,use a rinse agent like finish, and spray off dishes before loading.About 35yrs. ago I use to be a dishwasher as one of my first job's and if you did'nt spray the dishes and scrap them off before loading,the dishes would not come out clean,And after each shift the dish washer would be cleaned out.

I have changed the battery yet it still won't start. It just keeps trying to fire but wont.

So it will sputter but won't start. You will need to remove and clean the carb. It is partly clogged and just letting eough gas through for it to sputter but not start. Or you can try a new spark plug somtimes that will make it act like that to.
