Q. Over the past couple of months, my dishwasher cleaning performance has dropped. It had problems with leaving a white film on the dishes, and I was able to get that under control by using some recommended acid agents to clear it up. Now the dishes no longer come out clean. The unit runs all cycles and seems to be doing the job, but grimy dishes come out. I have to rewash about 50 percent of the dishes, and the ones I didn't re-wash are not good and clean, either. We always rinse the dishes before we put them in. The unit drains fine and I do not see any food accumulating in the drain area. The pump motor was replaced under warranty about three months ago. Any ideas what to check?

A. Sounds like you have a low water fill problem or maybe a water temperature problem. The water should be at least 120 to 130 degrees Fahrenheit to start with. Gel soaps can cause a lot of problems with scum and leaving a white residue, mostly when there is not enough water in the dishwasher. After it fills there should be water almost up to the heating element. Also look for the water draining by itself.


Q. My dishwasher and garbage disposal both work fine. However, I frequently find out there is a lot of wastewater back from garbage disposal that smells bad. Sometimes, there is so much dirty water it flows out onto the kitchen floor. I cannot figure out why.

A. Possible causes for the problem you are describing may be a plugged and/or restricted drain line from the appliances or the main drain line. Plugged or restricted drain lines need to be snaked out using a plumber drain cleaning snake. These can be purchased or rented at rental yards.

You will likely have to remove the lines from both appliances to ensure those drain lines are cleared of any debris inside of them. Also check the main drain line into the sewage line. Any plug or restriction will cause the drain water to back up and overflow. The dishwasher's vent cap on the sink may also be the cause of the problem. It may be a good idea to replace that part also.


 Q. I have a sand-like substance in my dishwasher. My dishes dry with this grit on them, leaving my dishes dirty. How can I stop this from happening?

A. If there is sand or sand-like sediment in the dishwasher and it did not arrive there from any item(s) washed in it prior, it arrived via the water supply. This means it came from either the water supply or from the pipes in the house, if the pipes are corroded old steel or iron pipes. If it came from the water supply and/or the piping system, it will also be in the washing machine and all other water using appliances. Check the aerators on the sink faucets and inside the toilet tank. If any of those locations have the same problem, it may be the water supply or the water piping system. In those cases, other major problems exist, which will not resolve the dishwasher problems.

Some of that "grit" may actually be coming from your dishwashing soap. Try to remove the screen in the bottom of the dishwasher and clean all the stuff out that you can. Run the dishwasher a couple of times without anything in it to further clean it out. Put some clean dishes in it and run it again to see if you are still getting the grit on the dishes. One problem is that some dishwashing soap needs very hot water to dissolve properly. If your dishwasher is a long way from your water heater, the water inside your dishwasher never gets hot enough. You will either have to change soaps to a liquid type for dishwashers, or you may be able to run the water in the kitchen sink until it gets hot and than turn on the dishwasher. This seems to work for the first cycle, but you will have to do the same thing when the next cycle begins, or do not put any soap in the second soap dish.


Q. I have a Kenmore Ultra Wash II that is about 10 years old. For some reason dishes are not coming out clean, even though it has worked great for a long time. I haven't made any changes in soap, loading dishes, etc. Any ideas on what to check? The arms seem to rotate OK when it is not running and everything "sounds" OK when it runs.

A. The filter screen beneath the lower washer arm may be restricted with debris, soap scum, hard water deposits, etc. Remove and clean it even if it looks OK. Beneath that filter may also be debris and/or some form or type of restriction.

When accessing the lower filter screen, you will have to first remove the lower rotating washer arm. Clean the water discharge holes, too. Be sure the inlet to the washer arm is clear also. Same for the water feed into the arm.

Note the water level. The filler float may be stuck or restricted in its free moving up and down travel distance, restricting the water fill volume. Lots of other possible causes may be related to water flow, like a defective pump, hose restrictions, etc.


Q. I have a whirlpool dishwasher that seems to be working OK, with one problem. The heating element had a significant amount of white hard water deposits built up on it. After one cycle, the buildup (or the element itself, I can't really tell) is burnt and smells burnt. The dishes seem to get clean, but they retain a burnt smell until I rinse them with water from the sink. I've tried rinsing the dishwasher with 1 1/2 cups vinegar, but that didn't fix the odor or burnt residue that can be rubbed off of the element with a cloth or nylon scrub pad. Is there a way to get this stuff off the element, or will I need a new one?

A. It sounds like a lime scale buildup. Try using Lime Away along with your nylon scrubber. Don't put Lime Away in the machine and run it. You don't want to get that stuff all over the dishwasher. Pull the plug first. Once you get the junk off, look the element over closely for a breakdown on the sheath. If you find that, replace the element.

"PF" means power failure. The first thing I would check is proper connection at the power outlet.

Remove the bottom panel and check how the power cord is connected to the dishwasher.

If there is nothing wrong then check the door switch, the wire harness and the last thing is the power board board.

Appliance Type: Maytag

Appliance Brand: QuietSeries 100

Model #: MDBTT59AWB

Serial #: 22272839AE



The buttons on the front stopped operating, or at least the one we used most frequently (Light Wash) and the unit would only go into "Heavy Wash"



I bought a new touch pad (from ApplianceZone - thanks), which consisted of the entire top of the door and it worked well for about a week.



Now - no lights come on until I press start, and the only mode it will go into is "Light Wash" with "Extra Rinse".

If you've replaced the touchpad, the control board may be bad. I've linked it below.

My Whirlpool Dishwasher (Model# GU2500XTPB7) was running a cycle and got down to 44 minutes, the panel still showed that it was soaking and it will not do anything else. the panel shows -- and will not resume when pushed. I am thinking that the control board might have gone out. I have unplugged it to try to reset it and nothing different happens.
