MDB3100 Soap Dispenser Problem

You advised to change water inlet valve, which I did. It works, but soap is still left in the cups even after a heavy cycle. Only used 1 Tbsp in each side, water seems hot and pressure good. Any ideas?

thanks

    Thanks for this, it looks like very good advice and I will certainly give it a shot this weekend. Then will give proper follow up, including rating. Thanks for such a detailed response.

    Your help was great in replacing the water inlet valve, but other issues surfaced. Decided to just replace it instead of messing with it further. Fam was getting on me to get it done, and didn't want to pay a guy to fix a machine nearing the end of its service life. Will definitely be back on this site, as the help from you has been outstanding.

    Thanks again, I saw that the water level after the 10-sec delay after main fill was just touching the heating element. It didn't lose level, it just didn't fill quite high enough, so at that point I figured it could've been a float and/or a float switch problem. But I just got sick of messing with it basically. Kind of a cop out on my part, as I'm sure if I had more time to deal with it, your advice would've been just what was needed to get the job done. But like I said the washer had been down for about a month, and the natives were getting too restless.

In the main wash, once it fills completely, stop the cycle, ccount to 10 then open the door and observe the water level. It should be filled to over the heat element and covering the pump cover. If you observe that then it is ok there. If the water level starts falling then you have a siphon issue. Your drain hose must then be adjusted to go across the top of the dishwasher and then form and form a dip or a loop so that you have a "trap" in the line and then attach it to your drain connection. Elevating the hose and forming a trap should eliminate the water drainage. Also, if the water level is correct, you should be able to listen to the wash arms rotating with a rhythmic, whoosh... whoosh, sound. If you observe this then it has to wash the soap out. If the water level is normal and you don't hear the whooshing, then you will have a possible filter or pump issue, which will require disassembly and inspection.The filter can be removed and cleaned under running water, using an old toothbrush,or similar brush to clean the holes. Also, you will want to inspect the upper and lower wash arms for obstructions or lime build up. Follow the link below for disassembly procedures and parts.

What would cause a Whirlpool Dishwasher DU1148XTPB3 Soap Dispenser's trigger/spring to continuously try to open the soap dispenser after it has been opened.
Question edited for multiple spelling errors

Because water hammer is nothing to do with the soap dispenser! In fact nothing to do with the dishwasher, apart from it requesting water from the mains supply. It goes all the way back to one of your main water valves although it may be the water inlet valve on the dishwater. You need a 'water hammer arrestor'.

Dishwasher does not clean dishes, soap does not fully go away
Water Inlet Valve

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.
Heating Element

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.
Filter/Drain Grate

There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishw ashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher. Consult your owner's manual for specific directions for removing your dishwasher's filter and cleaning it.

  • . Detergent or Detergent Cup

    It could just be that you aren't using enough soap to completely wash your dishes. Your dishwasher may be designed to dispense soap at two different times during the wash cycle. If you don't fill all of the detergent cups, then the diswasher will lose a cleaning cycle. Also, if you use a gel-type detergent, try switching to a powered kind. Powders tend to dissolve better in hot water. And don't buy in bulk. Detergents are most effective in the first two weeks. After that, they decrease in potency.
    Alternatively, your dishwasher's detergent cup could be defective in some way. It is possible that it is gunked up full of built up detergent, and a thorough cleaning may be enough to get it working again. If that doesn't do the trick, you probably need to replace the entire detergent cup assembly. If your cup isn't even opening, My dishwasher detergent cup won't open.

    Cycle Selector Switch
    Sometimes a dishwasher's cycle selector switch is the reason why dishes are not coming completely clean. Test your selector switch to determine whether or not it has become defective. If it has, replace it.

    LG 2077 CW-has IE code issue as well as soap dispensing problems
    IE is an inlet error indicating that the machine has not filled up to the correct water level within 10 minutes. Could be a bad inlet valve, low water pressure or a problem with the inlet hoses (do not use anti flood hoses with these machines, use only the included fill hoses).

    It sounds like all of your problems lie with the water fill. If the dispenser compartments do not get water added to them then the soap, bleach, and/or softener will not dispense properly. Then it will still be present and may dispense on the next load instead.

    It is also VERY important that you use an HE (high efficiency) detergent and the correct amount (2-3 tablespoons per load). Otherwise you could end up with oversudsing issues which can also keep the bleach from dispensing properly.

    Also make sure to not use GEL bleach, GEL detergent or GEL softener as they are too heavy and will not dispense properly. If all of these recommendations do not help then there is a definite issue with the incoming water supply from the inlet valves (especially if the IE errors continue). In that case you will need a technician to check the inlet valves inside the machine.

    Hope this helps, please rate my solution.

    Maytag MDB3100 Soap Dispenser Problem?
    Remove each arm and inspect the small spray holes for plugging. Use a vacuum in the center hole and poke out each plugged hole. Unless your vacuum allows wet pick-up, make sure the arm is dry first. Try using a capsule type of detergent instead of liquid. You might have to tear down the lower spray arm assembly to the deck to clean the large screen which may be plugged with water/food deposits. Use hot water, detergent and white vinegar to clean the screen. Hope this helps!

    LG WM2277HS - water backing up into soap dispenser
    The pipe from the soap dispenser to the tub is quite large, it seems as if the water isn't getting out of the dispenser quick enough. Pull the whole dispenser out of the machine. There is a release clip at the back of the cup with the tray fully open. Clean out all soap residue and scum. Sometimes there is also a spot or setting for liquid or powder detergent. Adjust accordingly. Reassemble and try it again.

    Soap dispenser not working
    It sounds like the water valve has a clogged filter.  Shut the cold water to the washer off, disconnect the hose and remove the filter screen in the washer water valve.  Clean out the filter with toothbrush.  Reinstall and everything should be ok.

    Could SOAP DISPENSER be caked with soap???
    POWDERED DETERGENTS GET CLOGGED ALOT IN THOSE DISPENSERS. I ADVISE CUSTOMERS TO FILL THERE WASHER AND ADD SOAP WHEN IT STARTS TO AGITATE WHEN USING MORE THAN A 1/2 CUP OF POWDER ... THEN ADD YOUR CLOTHES ... THE WASHER HAS A SAFTEY SWITCH WILL STOP MOST WASHERS WHEN AGITATING OR IN SPIN CYCLE,SO YOU CAN LOAD CLOTHES ... OTHER THAN THAT ... ALL YOU CAN DO IS KEEP THAT DISPENSER FLUSHED OUT WITH HOT WATER AFTER EVERY WASH. JUST POUR HOT WAYER TROUGH IT ... IF THE WATER BACKS UP (EVEN WITH A SLOW POURING) THE DISPENSER IS PLUGGED AND NEEDS TO BE FLUSHED OUT WITH A HOSE. GOOD LUCK AND STAY DRY !!!
