Random Musings On The LavaTherm Dryer

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

By George, I Think I've Got It

Yesterday was a nice sunny but temperate day so did some wash in the AEG as part of a bit of Sunday house cleaning. First one must say have to note when the hamper is filling up in that this particular load gave a "120%" message from the Lavamat. This probably was because the bulk of the wash was thick and thirsty terry toweling and wash cloths. Indeed the reason one went for the AEG instead of Miele was wanted to get the whole lot done in one go. With the Miele the load would have had to be split as it really does not do heavy towel loads well. Find best to load the unit about half or three-quarters full otherwise the weight of saturated towels/wash cloths causes all sort of problems. You can often literally hear the drum hitting the bottom of the machine during the rinses when eleven gallons of water is used.

Being as all this may the Lavamat load once wetted down barely was 3/4 up the window but still am not going to take chances knackering the bearings and motor brushes.

Anyway wanted to dry the lot in the Whirlpool as one previously swore off the Lavatherm until cool to cold weather arrived in earnest, but again the dryer gods conspired against that happening. After trying for over an hour could not fit the newly purchased (yes another one) semi-ridged dryer hose to fit the WP portable. Was nearly impossible to get the hose onto the vent and screw the clamp on tight enough to it would remain. Each time one tugged on the hose to place it into the window outlet, it came off. GRRRRRRRRRRRRRRRRRR!

So away went the Miele and out the AEG. Split the wash load between bath linens and garments with the latter going first. Set the thing for "cupboard dry" and that was that. Decided to take a nap and was awoken about an hour or so later by the chirping of the dryer telling me it was done. Washing came out warm and slightly damp but once it was in the basket and folding began everything was dry.

Next came the toweling which already had air dried quite a bit awaiting it's turn in the Lavatherm. Set the dryer for "cupboard dry" again but also used the "quick" button. More napping and again awoken an hour or so later by the dryer saying it was done. Once again things were "moist" and warm but once taken out of the dryer and left in basket for folding things were dry.

Cannot say exactly how long each cycle took as was busy napping. Each cycle starts with a set time but the display changes often based upon what the sensors tell the dryer. So things may say "73mins) to start but if one comes back say in ten minutes that number has dropped down to 58mins.

Still no water to empty out of the container, but one isn't worried. Suppose spinning these loads either in the spin dryer or using the 1800rpms of the AEG means there isn't allot of water left in laundry.
 
Checked the drain port when the condenser was cleaned

Nothing, indeed made sure if it whilst cleaning the condenser compartment.

One can again only assume between using the max (1800rpm) spin on the AEG, and or several minutes in spin drier (3200rpms), there is not allot of water to drain away. This along with it being either temperate to only slightly cool when using the dryer could affect the amount of water being pumped away.

Suppose one could spin water laden towels at <900rpms to see what there is, but that would place more energy use on the dryer one's electric bill as well. *LOL*.
 
Oh Launderess, there should be some water to empty in the container after that. I certainly can't do 2 loads in the Lavatherm without emptying. Do check for a leak or some peeking around. If the load was half with only polyester I could understand very little water, but towels; no.
 
I've Got Nothing

Shoved dryer away from wall and nothing seems amiss behind or underneath. There was a small spot of powdery dried something, but it wasn't on the side of the dryer where pump is located nor large enough to suggest any sort of vast leak. Blew down the drain hose that can be used if one redirects water from the drawer and heard nothing but a whistle. That sound went up into the drawer area and also down towards condenser.

Again pulled out the condenser unit and the compartment is clean with nothing blocking the drain areas.

For the wash done this weekend only the Lavamat was filled to capacity (about 20% over if the machine's sensors are accurate), but for drying load was split into garments (vests, under garments, socks, night clothing, etc..) and bath linen. Do not know how long the first load (garments)took as one took a nap, but by the time one awoke to place second (bath linen) they had pretty much mostly dried from sitting in the basket.

Being as all this may will shoot off an inquiry to AEG Canada to see if one should be concerned. One is still going on one's personal theory that since so far every load that has gone into dryer has been spun to death, and that weather has not been very cold/dry there just isn't that much condensation going on. Could be wrong for lord knows the AC creates plenty of water, but that is an active system versus the passive of the Lavatherm.

Know from various Internet posts this particular model of dryer has been known to play up. Usually this takes the form of the "empty water" signal coming on even when drawer is empty. So far we've had none of that. Suppose one could send things to the dryer from the Miele washer (final spin only 900rpms) or use a lower setting on the AEG Lavamat to see if more water is "evaporated" into the drawer, but at what cost to one's electric? As it tis this thing takes longer to dry a load than my Whirlpool vented and aren't looking forward to increasing that time by putting in sopping wet laundry.[this post was last edited: 8/27/2013-21:49]
 
If:

If the machine drying loads just fine, and there is no evidence for leaks I wouldn't bother calling AEG Service. Whilst I am uneducated about these "things," provided nothing is running amiss during the cycle, you should be fine. Perhaps your house is dry enough that condensed water simply evaporates into the air, or the machine is pumping the water out like you suggested.

Just keep an eye on the machine for the next few loads. I wouldn't even try testing it's capability. Electricity is too expensive for that these days!
 
Thing Is If There Is Some Sort Of Water Buliding Up

Inside the dryer surely it would have caused sensors to react by now. Am referring to the infamous "empty water" messages and subsequent shutdown of the dryer if it senses water is backed up and or tank is "full".

Getting at the pump means at least taking top and one side panel off the unit, am not sure want to go poking around inside unless purely warranted. Again will contact AEG Canada in the morning to see if there is cause for concern.
 
Problem Found

At least one thinks has sorted things out.

Look at he vid of a Lavatherm being taken apart for cleaning. At the rear you can see there is a small black connector leading off the white hose from the drain pump to the condenser compartment "nipple". Ours is not like that at all. The hose simply sits as is. If this is the case no wonder water isn't reaching the condenser drawer as it cannot be pumped into anything.

Dryer was sold and arrived this way so am not sure what happened to the bit and or what previous owners arranged.

 
Oh dear how to feel really old !!!

I thought I was watching a middle aged gentleman when I realise I am watching a BOY I now feel ancient :o( but how wonderful he knows his stuff thats for sure!

Aside from the connection one still is now wondering where water is going if any at all is being evaporated out of laundry.

Gigged up a solution (bit of tubing and a worm clamp), but after a test of hosed down sheets (20min timed cycle), still nothing.

Oh well off to bed and will speak with AEG later on, one hopes the egits that shipped/delivered the unit didn't mess something up by stacking unit sideways during delivery.

Cannot imagine the installers would have left this hose either without being connected to the drawer. Unless previous owners used a hose to sink drain system. However when one checked the dryer was still programed for drawer.

Am beginning to *hate* this machine.

Can tell you one thing if the solution is another expensive part that costs equally dear to be shipped from Canada that is O-W-T, out.
 
Dear Launderess

I understand your distress but I am thinking maybe the lack of water could be due to a seal letting steam escape or something as silly. One thing you can check is when you remove the condenser with the dryer running can you feel the warm air at the front and cooler more harsh air near the middle if you can then the fans are working but that means the condensate must be going somewhere it cannot just evaporate there should be too much. I have never stripped down an AEG dryer only a Miele and in that if things are not working right there is a load of insulation material that soaks up any leaks so it takes ages to discover an issue. I wish I could be of more help but with luck someone else will be able to make sense of my ramblings and be of more assistance to you.
Good luck anyway lets hope no parts are required.

Sounds like

Its a blocked or broken water pump, these things and the tubes are so small that they easily get blocked with lint and clog...If it is not working then the condensate will build up in the lower pan and start to fill and overflow when its full because its not pumping to the empty drawer at the top...usually and warning light my tell you or a float will activate to stop the dryer!!

They are easy to replace if you get the part and like taking meccano apart and have a methodical mind, but you do have to take the back and side panels off to get to it etc....one thing I like about the new cheaper Hotpoint range is that they have a simple panel to get at the pump and its snaps in and out quick fix!!

Best of whatever you deceide, but its too good a dryer and set for the price to ditch!!
 
Sorted

With side panel and lid removed ran some test as directed by AEG that proved pump is working perfectly with no blockages in hose. Long story short several successive half liters of water placed into sump with machine on were promptly sucked up (the sound is not unlike a child having a Slurpie), the hose and deposited into drawer. This was possible via the jigged up connection by using a bit of clear PVC 1/2" hose clamped to one end and inserted into nipple in back of drawer compartment meant to take up water. Not pretty nor elegant but that's me for you.

Tech agreed after four loads there should have been a good amount of water in condenser drawer. Was promptly that well disabused of any notion that water simply "evaporated" by AEG tech. "Madam", he said, "that just does not happen, can assure you if water was produced by drying it went somewhere...either up the hose or onto your floors...". My comments about floor being dry and one not having noticed any damage and so forth did not sway his mind one bit. The man further went on to say this is a common problem with new installs of these condenser dryers. Apparently they arrive not connected to the drawer in case customers which to choose sink or bucket draining (via special kit), with the rubber end bit separate in a bag or something. Tech further stated that he has gone on many service calls where said hose was left unconnected and water drained for years behind the machine. Go figure.

Was that well told again in that regardless of what one noticed water went up the hose and simply sprayed or otherwise leaked out. It could not go back down into the machine as that would cause the sump to overflow which would stop the machine. Indeed the entire machine is designed so that if water does go where it shouldn't it generates a fault signal and dryer shuts down, *period*.

Wanted to take some pictures of inside unit but camera's battery was dead. However must say this dryer cannot have been used often. Despite the condition of the condenser heat exchanger (filthy), the inside of this dryer is champion, totally mint and clean. Not a bit of excess fluff or whatever to be seen.

After watching several successive sump full of water being drawn up one got tired of that and put the machine back together, satisfied all was as it should be.

Tech could not explain where the black rubber end piece had gone and AEG certainly was not offering any sort of free replacement. Part costs $13.50 (USD) with $27.50 for shipping. Spending over $30 for a bit of rubber simply was not on so that part will stay in Canada for all one is concerned. Long as the impromptu design holds am that well satisfied. If worse comes to the worse can always use the balance of clear PVC hose to jig up a "drain kit" and sent water into a bucket or similar container.

Interesting thing is that AEG changed the design of the float for these condenser dryers. Instead of a Styrofoam float there are electronic sensors. Nearly had a heart attack when side panel was removed and didn't see a bit of white foam over the sump. Where could the float have gone I wondered.
 
With our old Electrolux dryer - different design - I could sometimes hold my glasses against certain parts of the housing and they would fog up. Although I think you should feel an increase in humidity if the dryer leaks that much steam.

 

 
Technically

FWOU a good condenser dryer designed is a closed system with little to nil steam escaping. What should be going up the drain hoses is vapor condensed back into water. Now the dryer itself does get warm during operation, and of course if one opens the door it is rather like a sauna.

The more one researches about these sort of dryers persons either love or hate them with a passion. Have to say much depends up on design and build quality. Some reviewers of latest Hotpoint condenser dryers aren't good at all. Indeed if you get a year of use out of the thing that is considered well served.
 
Musings of an AEG...

great news, glad you managed to find a fix, now normal dry can be resumed!!

Like anything reviews are reviews, whilst many new appliances suffer from stripped back build syndrome, issues often start from non basic maintenance of the appliance, Hotpoint still offer great value for money, a bearing kit with felts and rollers is usually £17 and the snap in, easy access water pump design is a great feature that should be adopted on many big pound dryers!!

Happy Drying!!
 
That would be....

Correct, Hotpoint like many manufacturers offer a three tier sales offering, Aquarius being the entry level of old, Ultima are the mid range and Aqualtis are TOL....

The CDT00 (Condenser Tumble Dryer) is the basic timed condenser dryer..

By the % of units sold one would expect Hotpoint to have the larger share of issues and less favourable reviews - great value for money still!!

Great to hear that you were able to fix the problem. I hope you're all set now for problem free condenser drying.

The amount of vapor released from a condenser dryer is mainly related to how well the system is sealed. It's not only related to brands but also model lines. I'm very happy with my 1997 Miele condenser dryer. It's an older model with the smaller door. It's very well sealed. The humidity level in the small bathroom it's in, is never higher after using it.
 
Now on the new EU enegy label, the condensing effectiveness is mentioned, what I find verry good. Like Miele reaching A+++ while still having condensation class A (means more than 90% of the restwater in the load is collected), while Bosch always only gets B (more then 80%) and Indesits reaches as well as Samsung inly C (more then 70%). Miele dryers all reach A. Non modell seld today releases more then 9% of rest humidity into the air...
 
Everything Is Kippers & Marmalade Now

Did a small load in the Miele yesterday (duvet cover that was stained and a few sheets and small items), and after a trip in the spin dryer bunged the lot into the AEG. Weather has been very humid these past few days but since one had the AC on the night before indoors was rather cool and dry. Only wanted to get things near damp then planned on hanging them up to finish drying anyway.

During the cycle peered over the back of the dryer to see what there was; could see some water being pushed up into the drawer and the distinct "slurping" sounds of the pump sending water and or air up the hose. At the end of drying the drawer only yielded <1/2 teaspoon of water, but everything must start somewhere.
 
Water, Water

The float chamber basin down below will fill with the condensed water before the float and pump kick in to pump the surplus water up to the top container, from this point on you will be able to see how much extra water is being evaped from subsequent drying loads!!

If at this point the next load of towels / cottons still only measures a tablespoon of extra water being pumped into the top container then you have steam evaporating within the dryer from worn seals!!
 
Would Hardly Suspect Worn Seals

As both the washer and dryer are pretty much new. They were unblemished until those fools at HomeDirect got to them, but that is another story.

Should have taken pictures of the inside of this dryer around the sump and under the bonnet. Tis almost spotless with nary a bit of fluff or dirt to be found. The chamber that houses the condenser was another matter. But that was from previous owners not cleaning the heat exchanger before moving on.

Place isn't so much as more damp when this dryer runs as to increasingly warm as the dryer gives off heat from the cabinet. This one supposes should be expected from >2500Kw of heating power.

Both the duvet cover and bed linen spent >5mins in the spin dryer after coming out of the Miele. Between the 900rpms of the latter and 3200rpms of the former quite allot of extraction takes place. Shouldn't wonder why vast amounts of water aren't being condensed. Picked up this habit from using the small Whirlpool compact/portable which only has 1450w of heating power. It will dry a full Miele load in <40mins but things must be extracted to death for it to do so.

Still we shall see what there is when cooler weather arrives and one does say a full load of towels or a heavy cotton blanket.

Should also say am keen to keep electric usage down with this dryer; rarely aside from last week's double load allow things to say in long enough to become "bone dry", as it were.
