Samsung Dryer DV350AEW/XAA auto dry not working

13 posts in this topic

Greetings!!

 

So, first off.... We bought this dryer only 3 years ago, so its out of warranty.  Who purchases those extended warranties?

Well...I wished I would've!!!

 

I always use the Normal setting, high heat, auto dry.... it  supposed to shut off when it senses the clothes are dry.   Just yesterday, it stopped running after 10 (or so) minutes and has done this a few times since (inconsistantly).  I always clean the filter every time.  We checked the duct work and cleaned things up a bit.  Cleaned the sensor strips (they weren't really dirty at all..??). 

 

When I first turn on the dryer, it'll show 42 minutes on the dial (like it always does).  I never really stood there long enough to see if the time changes drastically (or not).  Currently, I'm trying the 'more dry' setting to see if anything changes.

 

I would assume this is 'sensor' related....??  But I honestly don't know......  Getting this thing out to diagnose is going to be a PITA. 

 

Any suggestions?

 

Thanks ahead of time!! Loved this dryer....until now.  Why can't things last anymore?

If your model has a timed dry cycle try using it, see if it completes a cycle without any fault codes.  Sounds like a moisture sensor issue but if the operating thermistor is bad it may display a "TS" (I think) fault.

Can you use the diagnostics to recover past error codes?

If moisture sensor checks ok then main control is at fault. I've replaced a few main controls for this issue(moisture sensors are simple and therefor reliable)

I would replace the thermistor, it may opening or shorting after running a while. Or, it may just be out of spec enough to confuse the CPU. And, You may want to replace the belt. I find a lot of Samsung dryers that have a frayed or broken belt when only a couple years old.

Awesome and THANK YOU!!  I was a little busy yesterday and didn't have a chance to work with the dryer.

 

I have printed out all your responses and should have time today to do some troubleshooting!

Performed the diagnostics procedure (for the most part). After going into that mode, a "0" showed on the display.  I proceeded to put the wet towel on both the sensor bars.   Nothing happened. The display still said "0".    I pressed 'Signal' again and got a 178.  I"m not sure what that number means..... so I just hit 'Signal' again and it was back to "0" again.

 

I clean the lint filter out every load, but we thought we should check the entire outlet pipe. Dragged the dryer out and pulled all the hoses. They looked pretty good. Cleaned everything up anyway....  most of it was built-up just below the filter screen AFTER the filter. There's 1/8" gap between the screen mechanism and the housing...where a lot of the air can go through without passing the screen.    Design flaw??  Or is there some upgraded filter screen I need to buy to get rid of this gap?

 

But anyway...since everything looked pretty clean, I'm not convinced this helped the issue.  Time to run some laundry and troubleshoot some more.

Just an update & questions:

Haven't done much laundry since - there's only my husband and I.

 

This little problem is sporadic.  One time it'll shut off and the next time it won't - so its hard to figure out. I'm still only getting "0" for codes.

 

Question:  Does this dryer sense the 'weight' in the drum?  And/or if the load is too wet or heavy?

I've never noticed any changes in wetness in the clothes I put in it.....

 

Question:  Does this dryer sense the temperature is too hot inside?  If yes, will it shut off if it gets too hot/moist?

 

This is a Samsung Dryer DV350AEW/XAA.  I always use the AUTO cycle on 'high' heat setting. 

 

Since this is so sporadic.....every other load so far.....  I'll just have to wait for the time when it'll do it 'all the time'.

Based on the questions above - wondering if I should make my loads slightly smaller and if that would change anything?

I believe I'm putting the proper amount in the washer - per instructions - and have owned front loader machines for about 10 years...??   

 

Thanks again!!

Reading material:)...

 

 

The complaint was identical:

"Laundry doesn't always dry" (and the vent system was ruled-out)

The responses were similar:

"Avoid small loads in dryers that have/use MOISTURE SENSORS"

or...

"For small loads---use the TIME DRY cycle"




There is a solution---and it's a very simple one.

Some years back---I had an older lady (widow)---that contacted us regarding her LG dryer.
Her complaint was that the laundry was not dry at the end of the cycle.
Also---the cycle run time/duration was rather short (cycle ended far earlier than initial time displayed).

In her case---she does not wash/dry large loads at all---and rarely does she even have medium sized loads to wash.

On LG dryers---the MOISTURE SENSOR ("bars") are located at the front of the dryer---on the LINT FILTER HOUSING.

If the dryer is dead-level---which hers was---a small load of laundry will tumble in the GIANT DRUM and very erratically come into contact with the MOISTURE SENSOR.

By raising the REAR LEVELING LEGS about an inch---this forced the tumbling small load of laundry to remain at the *front* of the dryer---continually falling/contacting the MOISTURE SENSOR.

On dryers (other brands) in which the sensors are positioned at the rear/back of the drum---simply raise the *front* leveling legs to get the same result.

Technicians can demonstrate to the customer by running the dryer with 2 or 3 small pieces of clothing---laundry will either tumble at the rear of the drum or near the center (in an LG dryer--for example).

Explain to the customer---the MOISTURE SENSORs function and that wet/damp laundry *must* continually come into contact with the sensor (show the customer the location of the sensor).

After adjusting the legs---the customer/owner will notice the laundry moving toward the SENSOR location within 30 seconds of starting the cycle---and remain at that location in the drum for the duration of the cycle.

Dry laundry.

That makes a lot of sense.... however,  I've run this dryer for 3 years without needing to prop up the legs and I almost always run full loads.

 

It might be something to 'experiment' with to see what happens to rule out/in the sensors themselves. 

I'd be concerned with the drum spinning 'off level' and creating wear/tear on the mechanics from a slight wobble in the drum.

(I work with machinery and only obvious I think this way ;) )

*************

 

The "wear & tear" would be negligible.

 

Dryer drum rotates at low RPM.

 

One to two inch lift (at the rear of the dryer) will not adversely affect dryer longevity/service life:)
