Water temperatures
Hi everyone. You have solve one of my latest doubts. I bought an LG washer-dryer combo model WDP1145RD about 6 months ago and has temperature options starting on tap cold (fria), 30, 40, 60, 95ºC, (this is how it comes on the panel, and have tried the cotton and the cotton eco at 95º and never reaches that temperature, (There´s a way to find out what is the water temperature at the moment by pressing and holding buttons Temp and Acl. en Esp at the same time) and it bearly reaches 67º in 95º Eco or normal cottons, so I thought that maybe the control board had something wrong, but I personally don´t want to contact LG service anymore since their technicians don´t know how their washers work. It happened once that a technician came and told me "I don´t know this model cause it´s plain new and they haven´t teached us how to repair this model, I don´t even know how to make tests or reset the control board and how to disassemble it" I felt really disappointed and angry.
I previously owned an Ariston washer which had "0, 30, 40, 50, 55, 60, 90º" temperature options and it reached the 90º, (I measured it once by lowering the drain hose and obtaining a water sample which was at 89º celsius) and it only had cold water valve. It took about 3 hours for the cycle to finish. On the last part of the heating, the machine stopped tumbling so it could reach the temperature faster and you could hear the water almost boiling. After it reached the temperature it restarted tumbling again for about 20 minutes, then added a little water to cool down and then came the first drain.
I own a 35 year old Mexican washer called Crolls Ultramatic 52 with 19 programs showned by letters A-M, with 3 temperature options on the control panel (60, 0, 75) all reachable to what they stated, (water temperature measured by me), just cold water entrance. There is also model Ultramatic 53 which shows letters A-O on the control knob and on the temperature settings it shows (60, 40 and 75), both models do the exactly same things, the difference is that 53 model has the 40º setting written on the control panel and on the control knob instead of having letters A-M it has letters A-O.
There is a BOL model 51 that just have 2 temperatures 40 and 60º settings and letters A-M. Models 52 and 53 have 2 thermostats on the outer tub which have 2 temperatures each high and low (30-60), (40-75) and are cabled in a special way. Heating element to 75º thermostat, 75º thermostat to 60º thermostat and temperature switch on 75º setting, 60º thermostat to 40º thermostat and temperature switch for 40º and 60º settings, 40º thermostat to 30º thermostat and 30º thermostat to timer.
Letter A heats up to 30º and tumble-presoaks for half an hour (4 sec tumble action and 7 sec pause) then passes to letter B which heats up to 30º and pre washes for 2 minutes then drains, it passes to letter C which heats to the other 3 temperature options (40, 60 or 75º), then it passes to D which is cold wash, before letter E it drains and now the rinses begin, with inter spinning between the 2 of them, letter F is the final rinse and has a different water entrance on the dispenser for adding softener, and then letter G is the final spin.
At the beginning of letter A, B, C and during letter D it alternates the tumble pattern from 7 sec tumble and 4 sec pause to 7 sec pause and 4 sec tumble every 2 minutes. Letters E and F just 4 sec tumble and 7 sec pause each click. A timer click before every spin, makes it tumble for 7 sec and pausing for 4 seconds while draining, I think in a form of "distribution" but when it gives the next click it spins at full speed not minding if it´s out of balance and sometimes this makes the washer to walk all over the place. Sometimes the water faucet and hose are the only thing that prevents it from walking away LOL!!! The timer clicks every 2 minutes except for when its heating (until the temperature is reached).
If you choose your cycle since letter A and 75º setting, it takes up to 4:00-4:30 hrs depending on how cold the water is at the moment, like on winter season. Letter A with 60º 3-3:30 hrs, Letter A at 40º 2:30-3:00. I usually use letter C at 40º (color clothes) and takes about 1:30 hrs or letter C at 60-75º (white clothes) and takes about 2:30-3:30 hrs.
Letters H-M are for delicates so the tumble pattern is just 7 sec pause and 4 sec tumble through all the letters, without spinning and having neutral drains instead of whatever tumble pattern like the first cycle does, getting dripping wet clothes after it finishes, it heats in letters H,I J,K, just to 30º always, so the temperature settings don´t work in this cycle. I guess it does it this way for not ruining any kind of clothes but activating detergent´s enzymes.
I will translate all the program chart of model 52.
A at 75º - Heavy soiled white clothes BIO.
A at 60º - Heavy soiled color clothes BIO.
A at 0º - Delicate color clothes BIO.
B at 75º - Heavy soiled white clothes.
B at 60º - Heavy soiled color clothes.
B at 0º - Delicate color clothes.
C at 75º - Normal soiled white clothes.
C at 60º - Normal soiled color clothes.
C at 0º - Synthetics with spin.
D - Cold wash
E - Rinses with spin
F - Fabric softener
G - Final spin (it says Centrifugado Intensivo = Intensive spin)
STOP
H - Nylon Perlon ETC.
I - Synthetics with prewash.
J - Permanent Press
K - Wool
L - Rinses without spin
M - Rinse for synthetics
STOP

I don´t have model 51 program chart but I guess it must be almost the same. The 3 models use the same timer. On the tumble pattern they are just the same as on the rest of functions, leaving the heating part and temperatures beside. Model 51 use 2 thermostats as well, but 1 of them has only 40º, and the other one has 30º- 60º, it heats up to 3 temperatures comparing to the other models which heat to 4 temperatures.
I´ll show some pictures of the machine so you can understand me better and will upload some videos of the different parts of the cycles in other for you to understand the tumble action patterns, and all the phases this machines goes through. It´s my best machine. The only one that doesn´t leave any soil on clothes. Features I like most: it has 6 lights to indicate what the machine is doing. Left row 1º - Machine on; 2º Full water level; 3º Heating, Right row 1º Tumbling; 2º Spinning; 3º Draining. Things against it: Capacity (5 kg) and spin speed (just one) 400 rpm. It was one of the first mexican-built automatic washers brought by the Spanish, and stopped it´s production about 21 years ago. All made out of steel and porcelain outer tub with stainless basket.
This were the only models that heated the water. There were a few models called Novomatic 21, 31, 33 that did the same things on the tumble pattern and functions except for heating the water so they had 2 water valves and their cycles were more than short. Instead of having letters on the control knob it had numbers and depending on the model was the cuantity of numbers it had from 1-7 divided in each side of the control knob to 1-15 also divided on the 2 parts of the control knob. This are quite simple machines, with the same mechanism everyone, just some models didn´t heat the water.
Finally, I guess changing thermostats for thermistors is why the make the difference between being reacheable or not the temperature shown on the control panel, since thermistors are way more sensitive than thermostats.
I hope I din´t make a mess on all my explanation. I´m still learning english and don´t know how to simplify things yet. I´m really sorry if I made you sleepy or your head ace.
Here is the picture of the LG´s control panel on the option side of it.[this post was last edited: 5/26/2013-01:35]
