Lg dishwasher fill then drains

This is a heater error. The cause is either a bad heating element or bad thermistor (the thermistor is part of the heater assembly). The heater assembly will need to be replaced.

Hi. this may be caused be several issue that i will discus below. Kindly read over the list that will describe several issue that may be apparent. replace any parts that corresponds to the issue you are having.


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Hi

Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter.

Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines.



First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. Has the disposer been replaced recently? If so, chances are the knockout is still in place. Simply remove the drain hose from the disposer, and knock out the plug. If the disposer has not been replaced, try removing the drain hose from the disposer and use a wet-dry vacuum (prepared for water, of course) to **** any water (and hopefully anything else) from the drain line. Then reconnect the hose, and test the unit. If you have checked the air gap and the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher.

Please do rate the solution and revert for further assistance.

Thanks

Had a similiar problem I tried reducing water pressure from water inlet (external to dishwasher) and this worked to a certain degree, although may result in being unable to fill, if you turn down too far. Water silencer (try plumbing stores) was fitted between mains and dishwasher and this fixed the problem.<!-- from fixya rte -->

This happens to my LG dishwasher every 6 months or so. It also makes a groaning sound as if the system is starved for water. The resolve the problem by removing the dishwasher and laying it over on it's right side. I then remove the two plastic assemblies that are on the left side and I remove them from the dishwasher (you will need a vice grips to remove the hose clamps from behind them, you will also need to remove the round circular water intake plastic disk that is on the inside of your dishwasher on the left hand side right in the middle of the left wall) and clean them. Once the water can run freely through these plastic parts you will get a good water flow and you should be fine. Until you have time to do this I recommend putting a few quarts of hot water into your dishwasher once you start to hear the groaning problem. This solution should be very easy for anyone who is comfortable doing their own oil change. Oh, and turn off the power supply first.
