Question about LG 24" XL Tall Tub Built-In Dishwasher - White

Open Question

I have tall tub model: LDF7920WW. It is not drying thoroughly; the walls are full of condensation & dishes are damp. I operate the dishwasher late at night & unload the following morning. I am not sure if my dishwasher was properly hooked up by a reputable plumbing company in my city. The authorized repair service tells me the problem with my D/W is that I am not using a rinse agent. I do not use chemicals like these in my home, let alone on my dishes. Is this the only probability of my problem?

    LG models are very energy efficient. They dry using a condensing vent system which requires the use of a wetting agent (such as jet dry). Many other brands use a large heating element and some use additional fans, which use much more energy, but even they say you should use the jet dry.



    Again, in a LG dishwasher, use of a wetting agent like jet dry is required for proper drying.



    The dispenser has an adjustment on it to allow setting for the minimum use required for your water hardness level, but some type of wetting agent must be used, unless you wish to dry dishes by hand.

    Thank you for your quick reply.
    Does water temperature make a big difference in how well the dishes dry?
    I started loading up the machine last night after the machine was empty for the day

SOURCE: doesnt dry dishes, top rack not clean, has been serviced 3 times

If you have checked everything that was mentioned (and none of them are the issue) then either the heater inside the unit is not coming on during the wash and rinse cycles and/or the fan motor inside the door is not coming on during the dry cycle. A technician can easily check this out with the correct tools and by putting the unit into test mode.

As for the top rack dishes being dirty and there being soap left in the dispenser, this sounds like wash motor is either weak or the vario motor is not switching between the upper and lower spray nozzles. The sump assembly should be replaced for this issue.

SOURCE: LG Dishwasher redepositing debris back onto dishes

Have had a problem with our LG 5811 Dishwasher not operating.
I have found the Vent Hole Cover located inside the Door was not installed correctly. I used plumber putty between the plastic fitting and the inside face of the Door and turned the Cover fully to lock in place (vent hole is toward Door bottom). Water was leaking previously from this opening over the wires in the door.

Another problem was the lower Door Seal (under the Door) it was not installed correctly either. It was actually too long and would not seal against the bottom of the inclosure. Water was coming out and spraying the wires in the door. I had to remove the metal stiffener over the front of the Dishwasher to get to the Door Seal. I removed one end and reinstalled the seal. The Seal laid flat but was approximately 3/16" to long. I cut off the end with a sharp knife - seems to be the correct length now.

Try these things in order:

-Try to use a name brand powder, rather then a generic. Even a small box. I had similar problems with my LG dishwasher when I tried to save money by buying a generic powder. My dishes did not get clean and white marks were left behind on my stainless steel DW liner and the dishes. When you ad the powder, do not over fill the dispenser. Add less than the full dispenser cup and close it. Place some powder in that shallow square indent on the dispenser lid to help the pre-wash cycle. Also, run the water in the sink until hot water runs immediately before you start the DW.

-If, after using Electrosol or Cascade for 2 - 3 loads and your dishes do not come out clean, then I would run a load of dishes without adding the soap. Start the dishwasher and wait for it to fill and begin to wash. Open the door and add one cup of vinegar (white vinegar is fine.) Feel free to ad another cup after the first wash water drains and the second wash water enters and the DW begins the wash cycle again. Run a load of dirty dishes with the soap and check for good cleaning.

-If the problems continue, it is time to remove the filter assembly by removing the 9 silver phillips screws from the filter assembly. You will also need to remove the lower sprayer arm by pulling straight up and then out. With a flashlight, inspect the sump area that was hidden by the filter assembly, looking for any debris that has jammed into anywhere down there. Watch out for broken glass as you feel around. Reassemble and test with a load of dirty dishes.

The poor drying may be caused by not keeping the rinse aid re-filled. Check that first.

Also, these water and energy conserving dishwashers actually use the "dirt" from the dirty dishes to help clean the dishes during the first two wash cycles. Simply clear the big chunks off the dishes and put the dishes in the DW.

Please report back what you find or if you have more questions. OK?

SOURCE: LG LDF6810ST Dishes Wet

To save energy, the LG LDFx810 dishwasher product family does not turn on the heating element during the drying cycle (third blue light blinking) rather it brings the final rinse water up to a high temp (I think it is 160 degrees (f)) and then uses a condensing drying system (mounted in the door) to pull the wet, hot air from inside the dishwasher. When it works, the dishes come out pretty dry (except for some plastics)

Check this:
-When the DW does its final drain, confirm that the water drained into the garbage disposal is really hot and not just warm. Be careful to not burn yourself and use a meat thermometer if you have one.

- After the water drains for the final time and the dishwasher blinks the third light, put you hand under the left hand side of the DW door. There is a slot down there that should be exhausting warm air.

If either thing is not happening, it is time to get a professional to check things out and make repairs.

Please post back here with what you find or have further questions, OK?

Why is our zsf6128 dishwasher is stuck in dry mode and cannot start it


I'll try to explain how drying works generally in the dishwasher.
Dishes absorbs heat and cools more slowly than a very thin wall of stainless steel.
The consequence is that water evaporates and in accordance with the Mollier diagram begins to condense on the walls of the stainless steel whose temperature is lower due to faster cooling of the dishes.
Now drying can be divided into two categories. Active and passive.
Passive way of drying the natural circulation of moist air and condensation in the condenser, which is usually located on the left or right side of the dishwasher.
Active way of drying works on the principle of forced circulation humid air with fun helping quickly condenses and thus speeds up the drying of dishes.
In passive mode the drying process can speed up the partial opening of the door.

How do I get the Electrolux dishwasher to dry the dishes?


Hello, I've got a suggestion and at first it may sound like I'm pulling it out of my...left field. I'll tell you the what and then I'll explain why. Try this, take a rag or paper towel and soak it with "rinse aid" AKA, "jet dry" and apply it to the top of the tub and to a lesser degree the sides as well. I suggest this to all my customer's with new dishwasher's. Now the why...all dishwasher's require assistance to dry your dishes, some more than other's. Hence the need for an additive such as jet dry, it is simply a wetting agent which help's the water run off the dishes and as a result they dry better. So why put it on the tub ? Glad you asked. The reason is exactly the same, on older dishwasher's that have had many year's of use the tub has already built up some wetting agent on the tub just by normal and continued use, the new obviously has not. The only jet dry the new one has is the added amount in the dispenser. Over a short time of regular use the unit would start to dry better on it's own, this just speed's up the process. By adding the jet dry to the tub you create a seathing action allowing water to run off before & during the dry cycle as to not have water in the form of condensation dripping back onto the dishes when the cycle is complete, which leaves you with dry dishes as opposed to wet dishes. Make sense ? I hope so, it really work's. Hope you found this helpful. If so please rate the info you received frome jere at "fixya" today and good luck. Let me know if I can assist you further. I hope you didn't find this too difficult to read, I had to use my iphone, it's the only internet connection I have at the moment. Macmarkus :)

My new Kenmore Elite panel ready dishwasher leaves wet


You need only enough space so the door does not rub when opened. If the unit is too far back under the cabinet the countertop (if wood) can be damaged by the exhausting moisture. The dry feature on the newer models is just as you describe. The moisture from the hotter dishes evaporates and is condensed on the cooler walls and door of the wash tub. Dry dishes wet tub is normal.

My bosch dishwasher will not dry the dishes


this dw to save energy works this way- the final rinse will reach a temp of 161 F . the dishes have to absorb this heat. when the cycle is complete the dishes become a heater in themselves radiating the heat they absorbed during the final 161 F heat. If you have any tupperware or plastic dishes in the unit they will not absorb heat therefore not radiate the 161 f temp need to dry all the dishes. try to avoid plastic items and they must always have jet dry. this is the european way of conserving energy. on the old ge or whirlpool they had electric element in the bottom that would bake the dishes dry ....not these..but they do save alot of energy.. it helps right after a cycle to crack the door open release all the steam from the unit
