Dishwasher tab not dissolving sometimes and dishes are not getting clean

I quit using the tablets a long time ago...just like you, they never really dissolved, and left residue on my dishes. I only buy liquid now, try a few out. You will be surprised when all of your dishes are actually clean, and nothing is left in your dishwasher when it completes. Best wishes with going back to where we started years ago...sometimes older things are better at doing things* Michelle~

Hi,

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...

The water may not be hot enough. Increase the temperature of the incoming hot water or try this: put the tab in the open soap cup so it will start to dissolve during the pre-wash. Then it will finish dissolving during the main wash. If the dishes get clean using this method you may not have to increase the water temp.

The water is not hot enough. It may be pausing to heat the water and when you open the door it resets and starts again. Check the electric element at the bottom that heats the water to see if it is burnt out.

check the filters. also check drain. Sounds like it's not fully draining and/or there is not enough water (ie. when filter are clogged)curculating to wash the dishes properly

I don't have a solution, but the exact same problem is happening with my dishwasher. Nothing is getting cleaned properly.

Did you manage to get the problem fixed?

It sounds like you have a water supply issue. If you are on well water the screen in the water valve may be clogged. You can access this, remove it and clean it on most dishwashers. It is located in the valve where the water hooks up to the unit.

Recommend you stop using the gel and switch to a brand name powder - like Electrosol or Cascade. Never use gel, gel packs or tablets in any dishwasher. Avoid untra-cheap, generic powders.
If problems continue, a service call, with them checking that the heating element is working is the follow up step.
Good Luck!

Sounds like you have motor pump problem and may need to be replaced.  The parts are covered for 2 years but you'll have to pay for the labor.  Call a qualified LG technician for service on your dishwasher.  You can find them on the LG website.

1. No waterMake sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.

2. Not enough water
If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

3. Clogged spay arms
There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

4. Water temperature is too low
To get the best results, the water has to be at 120 degrees Fahrenheit when entering the dishwasher.

5. Not enough soap
If you only fill one part of the soap cup, try adding soap to both parts.

6. Smoky film on dishes and glasses
This problem occurs due to excessive calcium build up inside the dishwasher. Try cleaning you dishwasher using a dishwasher cleaner.
