This error means that you have some kind of problem with the heater, which is responsible for both heating and drying. Either the temperature is too low, or vice versa.
Your dishwasher washes & rinses fine, you are having a problem with the drying part of the washer. It's the heating element. But just to be sure, clean out the bottom of the washer. You can simple unscrew the plastic nut from the bottom, lift off the cover & remove all debris. replace cover & nut. You could try to run the washer empty & let it have a good cleaning(I do this once a month) Cleaning the washer probably won't help the unit go into the dry cycle, but it is something you should do monthly, for PM. If you know someone handy they can replace the heating unit ordered from LG or your Manuel may give you some places.(or off the web) AND if you are lucky & the dishwasher is less than 1 year old it's still under warranty for parts only. Labor is what gets you. Again, most people know someone who is handy. Sorry I couldn't give you good news.
SOURCE: Stopping the Cancel/Drain Cycle
Disconnect the Drain Hose from the plumbing under the sink and using a bucket hold the hose in the bucket and attempt to drain the dishwasher. If you have a disposal and recently replaced it, the knockout plug may be still inside where the drain hose attaches into the disposal. To determine if it is still there, using a screwdriver, stick the screwdriver into the drain hose hole on the side of the disposer and if you feel blockage then the knockout plug is still in the disposer and will need to come out. To remove the plug use a short screwdriver and a hammer and place the screwdriver into the drain and strike the top of the screwdriver once and the plug should pop out of the disposal. Be careful not to hit the disposal too hard or to damage any plumbing. Reattach the drain hose and you should be all set. When you remove the drain hose if the machine is flashing an error code, go to the circuit breaker box and turn off the breaker for the dishwasher, wait 5 mins and turn it back on. This should reset the board and the machine should operate properly.
SOURCE: Display error code of Lr on control panel
L means "Lid or Door Lock" problem
r probably means 'release' I couldn't find it anywhere... so I'd guess that Lr means the machine did not detect that the Lid Lock released and cycle end (which means either the sensor is bad or the Lid Lock dosen't lock the Lid).
Either way, something with the Lid Lock system ais not right. Be glad it releases ;-)
SOURCE: Dishwasher stopped drying dishes at end of cycle
There is a heating element in the bottom of the washer. It is burned out and needs to be replaced.
SOURCE: Error code 2H
The control panel needs to be replaced (indicated by the "2H" error code displayed at the start of the cycle).
BTW - The number 1 displayed at the end of the cycle indicates the cycle has timed out (i.e., it doesn't mean 1 minute remaining). Hence the continued running of the unit. Until you replace the control panel, you'll have to manually cancel the cycle at this point.
