Greetings and salutations masters,
My dishonorable appliance has left me puzzled.
This early-nineties vertical washing center (dryer on top of washer) has a touch panel control that has been more than helpful over the years. It has all the options for a measly grasshopper like me to wash and dry without entering a lot of options. I only use "regular" to do my laundry. I have done so since I bought it.
My problem is that no button (touch button) works right now, except for the PERM PRESS option wich actually starts the washing cycle but I cannot turn it off because the OFF button is also non functional.
I have inspected and cleaned the panel itself and the circuit board too but to no avail.
Dishonorable unit lives under a shed in my backyard and I have always worried that dusty conditions might do harm to it. I beleive it has turned on me for not providing walls to shed.
Please help me regain the love of my unit.

If at least one thing programs, your transformer is good. You are looking at a board or Touch Pad. Below is the service manual link. Page 4-4 is the start of what will be your TP check. You will need someone to press and hold an option as you ohm out the TP. It is easier to remove it from the unit and lay it on the counter for testing.

| My wife had to do some loads today and she said the washer can do the whole perm press cycle BUT she can´t dry AND wash at the same time. I has to be either or.

| Wondering if you need to check the electrical to the unit itself, might have lost one leg of the 240 volts....

| Oh, both of these have all their three prongs. Should I look somewhere else along the cords?

| Because your model posting was incorrect, Pegi thought your unit was a electric dryer with a 240VAC line cord. If you have at least one function into the display that works, do the TP test. If you did not have the low voltage needed to the board from the transformer, nothing would light up or program so the voltage has to be good to that point. From there, your TP should still program any function for either the dryer or the washer. IF your incoming voltage was a problem, it might not run, but should at least program. YOU ARE SURE THE PERM PRESS CYCLE STILL PROGRAMS? For a quick test, if nothing is programing, look at the schematic in the service manual I sent you and test the transformer inlet and outlet voltages if NOTHING is programing.

We have been washing loads in perm press cycle. Yes, it is the only one working. We can´t wash and dry at the same time.
I am yet to find a meter to run the tests.

That is what you will need to confirm which component is bad. If you buy them from repair Clinic on this site, you can return them. Just a thought if you can not locate a meter. Usually, it is the Touch Pad. Meter or trial by error will determine though

| I also noticed the dryer program only available is REGULAR. It cycles completely but no other option is available.

I could not find the touchpad at Repair Clinic, only the pcb circuitry. And it is expensive . Can´t afford it.

OK, found the touchpad. Can´t afford it either.
Can we dig deep into the testing and try to detect the problem? Is my malfuction common in this type of part? What is the most likely culprit that I may try to fix? I can´t invest in the appliance at the moment and to me it seems that any one thing that I may do to it will either kill it or fix it.
We could go over it like in that "House, MD" episode where he is trying to diagnose a problem remotely on a chick who´s in Antartica. But I don´t know i you watch this show. Similar situations doc, I have NO resources.

I got more info.
The unit always runs with the buzzer emmitting a very dim and almost inaudible buzz. You have to put your ear to it to hear this sound.
Even in the off mode it can often be heard.
In humid conditions I have had to disconnect the unit because of an intermittent, bit-more-audible buzz coming from the speaker.
Hope it helps masters.

What I meant earlier was if we can identify a bad component in the circuit board that I may be able to replace with my soldering pencil.
There is a big capacitor on the back of the circuit board that looks kinda rot on one end.
I can certainly try to send you more detailed pictures of the entire board i you say it can help you look for something fishy.

| Only way to tell or be sure is a Meter. Would love to tell you to put a 8$ tstat in there, but that would not help a thing! Only way to tell would be to ohm out the TP as outlined in the service manual to see which part is bad. This unit is 20 years old or so, there where no prints available for the board. But if it is the Touch Pad, it would be a mute point anyway.

| Correct you are master. I will try to get my hands on a meter as soon as I can. I will keep you posted.
