Any time your LG dryer is having an issue of some kind, it’s smart enough to know where most of the problems stem from. And when it detects one, you’ll get an error code on its display.
LG has a number of different error codes that call into question specific problems such as a blocked exhaust vent or not enough water for a steam cycle.
LG Dryer Error Codes and What They Mean
Dryers are very sensitive to the amount of voltage being supplied to it. When there’s too little—less than 240 volts—then the dryer cannot perform all the functions necessary. The error code “nP” indicates that there’s an electrical problem somewhere. It’s less likely that it’s the dryer, and far more likely that it’s your home.
Start by checking the power cable’s position. Is it plugged directly into an electrical outlet or do you have it plugged into an extension cord or power strip?
If you do, it’s a dead giveaway. A power strip or extension cable is reducing the amount of volts the dryer needs. Plug directly into an electrical outlet. While you’re at it, inspect your electrical outlets for any damage like burns.
There may have been a power surge recently. Reset the circuit breaker. Turn it off and wait 10 seconds, then back on. That should give it enough time to reset. Of course, if that doesn’t help, then a repair might be necessary.
2. Error codes d75, d80, d90, and d95
The exhaust system is really sensitive to clogs. If it’s blocked in some way, then the hot, humid air that the clothing is producing from drying cannot escape in a quick enough fashion.
When that happens, you’ll get an error. If the exhaust is clogged as much as 75 percent, your dryer starts to display the “d75” error, accompanied by the Flow Sense displaying two to four bars.
At 80 percent, it’s error code “d80.” At 90 percent, it’s the error code “d90.” Lastly, d95 is when the humidity reaches 95 percent.
The source of the problem is linked to damage of the exhaust system or a buildup of some kind in the exhaust itself. Additionally, the exhaust should be adequately positioned with as few bends as possible, and as short as possible.
On the other side of the spectrum, if you see error code “PS,” then it indicates there’s something wrong with the power cable itself. Not enough voltage is being delivered to the power cable.
However, it’s more than likely that the red and white wire connections on the terminal block were swapped by accident. This issue can be fixed by switching the placement of the red and white wire connections.
A “dE” error code simply means the door isn’t closed. All you have to do is open it up and check that everything is in order such as the lint filter, the lock itself and the alignment of the door. In the event that the error code returns, shut the unit down, boot it back up and give it another try, but this time around firmly close the door.
Error code “E13” directly relates to the drain hose. It can be very sensitive to kinks, crushing, clogs, or freezing. In the event that any one of those affect the drain hose, you get error code “E13.”
Like the exhaust system, you don’t want unnecessary length added to the drain hose. If there’s an extension added, that’s more for the water to travel. Reduce the length of the drain hose if you can.
The lint filter can only sit correctly one way, and when it isn’t you get error code “FO.” Remove the filter and seat it into the slot so that it matches the curve of the dryer. It should NOT be sticking out at any weird angles.
There’s humidity sensors located on the other side of the filters, sensors that appear to be metal exposed along the filter. If they’re dirty, they can cause the “HS” error code, but more importantly it can run the dryer for over two hours. Clean them off and let the sensors dry before using the dryer again.
Error code “PF” typically happens when you’ve experienced a power outage, even a brief one. All you have to do is reset the dryer. You do that by unplugging the unit, holding the Start/Pause button for five seconds, then powering it back on.
9. Error codes tE1, tE2, and tE3
Error codes “tE1,” “tE2, and “tE3” all relate to the thermistor. The circuit board takes orders from the thermistor and uses the temperature information the thermistor has to determine whether or not the heating element should be used.
This one is simple: your dryer isn’t getting any gas. Check that the gas link is damaged or kinked. Additionally, the supply valve should be turned on.
“CL” isn’t an error code persay, but rather an indicator that the child lock has been enabled. It’s to prevent children from messing with the settings. Disable it by holding the Child Lock button for three seconds.
When you get the error code “Add,” it means there’s something wrong with your water supply for use with the steam cycle, for example. Simply add water.
