LG W/D Combo leaves clothes wet
« on: June 03, 2012, 09:15:24 PM »
LG W/D combo goes through entire cycle like normal but clothes end up hot, wet and steamed.  No error codes.  Any ideas as to what might be the problem would be much appreciated!

I have never worked on one of these, but maybe another tech will have some advice on it.

Here is the service manual for it.

About how old is it?

Is there any water being left in the drum at the end of the cycle? When you say wet do you mean damp, soaking or inbetween? What do you mean by steamed?

The clothes is not soaked but beyond damp where you can squeeze water from them, the heat is very high causing steam from the moisture on the clothes when you open the door.

Sounds like the blower in the drying mode may not be running. The first thing I'd do is check and clean the plastic exhaust duct in the inside right rear below the blower. This duct commonly gets clogged up. It needs to be removed and rinsed out. That's a maintenance item anyway. Take the top off and go through the test mode to make sure the blower is coming on. If it is clean the duct and try it in a regular cycle. If it's not check for voltage to it at the point that the test mode chart indicates it should be running. Have voltage - no run = bad motor. No voltage - bad m.pcb or wiring issue.

Check those things and post a result.

Cleaned condensing duct - was heavily clogged.  Put everything back together and went into QC test mode, on 13 don't think I heard the blower motor come on and got a DHE error - which apparently could mean three things -
The Dry Heater is out of order.
- Replace the Dry Heater
The connector of the Dry Heater is not connected
properly to the connector in the main PWB ASSEMBLY.
- Reconnect or repair the connector.
The Dry Fan Motor is out of order.
-Replace the fan motor.

Not sure what the dry heater is - is the the heater coil?

Thanks

The dryer heater is the heating element. But you said the clothes were hot so that would mean the heater should be working. The dhe code should have shown up in a non test mode cycle but sometime the pcb fails to show codes when it should. Recheck your heater and thermostat wiring and when in test mode make sure the heater gets hot at position 10 ( for 3 seconds - as the serv manual says ). And then that the blower is running at position 13. LG does not describe what the readings should be at the multiple pins of the blower connector and I have never had to go that far in diagnosing a blower failure. For now you have to assume that the blower motor is bad if it does not run when in test mode 13. The other possibilities are the main pcb is not turning on the blower or that there is a wiring fault between the m.pcb and the blower. Those other possibilities would be very rare. I can try to get more detailed info on the specs of the blower connectors but honestly don't count on me getting any good quality info on it any time soon.
