LG washer/dryer in one

[tnn]

I have this lg washer/dryer (WM3431HW) in one and the washing part works fine. When i set it to dry as normal and the time would be 2hrs and 50mins but it only dry for 30 mins.  Also when I set the timer to dry for 2hrs it seem like the clothes are not getting dry at all.  Can someone help me out?  I would call someone to come out and fix it but i'm scared the technician wouldn't know what to do or  try to cheat me off or something.

Hi,

I don't get the chance to work on many LG dryers myself, but you can download the service manual to your washer/dryer at this URL.

You will have to register for a free account and login before you can download it, but it's all free.

As with all dryers that take to long to dry one thing I check first is the dryer vent to make sure it is not kinked or getting restricted with lint build up. Lint can also build up over time around the blower housing adding to drying times.

Maybe another tech with more experience with LG can post some additional information for us later.

Could be something as simple as contaminated dryer sensors. The clothes rub them 2 bars and that is how the brain knows the clothes are damp. Get some windex and clean the sensing bars.

Oh by the way this is a ventless washer/dryer.

Can you tell where that sensor at?

[whirlpooltech]

The sensor JW is talking about would be inside the drum were the wet cloths could rub against it.

This is of coarse if your model has one.

How old is your ventless dryer. I have not heard good things about ventless dryers.

Its about 2006.  And when i set the timer to dry it doesn't dry and i think the water still comes out like its washing and drying at the same time.

From what little I know about ventless dryers...

The way they work is the moisture that is removed from the cloths in the dryer is collected in a sump were it gets pumped down the drain hose of the washer.

I have heard they are not very efficient and when working 100% like they should they still take much longer then a normal dryer would to dry a load.

When it was working ok how long did it take for you to dry a normal load of cloths?

[tnn]

yes this ventless lg washer/dryer takes at least 2hrs 30mins to dry a load

Maybe you need to remove the heat exchanger and clean it if it has one.
The pump on this washer is not an ordinary one. It looks as if it could have some sort of heat exchanger on the back side of it. I bet that puppy needs a good cleaning. Did is always take 2.5 hours to dry clothes? What is the norm?
