I would like to say "I'm sorry," to my wife for not listening to her complaints about the new washer not getting the clothes clean and not removing the soap from the clothes. Dear, I'm very sorry for not listening. I begain to get concerned when my sister was visting us and she complained to my wife that she was concerned about using our towels to dry with because they smelled so bad, and she was afraid that they would make her smell just as bad. At this point things started to heat up real fast, and I knew that I was going to have to do something before I found myself buying another new washer (which I considered), but what would I replace it with? If I bought a different brand front-loading washer, would it do a good job of cleaning the clothes? My first step was to contact the manufacturer, Whirlpool. The washer was still under the manufacturer's warranty period, one year. They agreed to send a service man to repair the machine. The only tool that the gentleman used while he was at our home was a flash light. It was a neat little flash light but it didn't know a thing about repairing a washer that was on the fritz. At this point I knew that the three year extended warrenty wasn't going to be much help in my quest for clean clothes and a happy wife.
Ok, lets get started. My original observation about the washer was that it wasn't using enough water to wash the clothes. The machine was only adding enough water to get the clothes wet, and you could hear them slapping around inside. The repairman had assured us that this was an energy efficient and enviromently friendly appliance, oh yes, "It's working just fine, just like the manufacturer had planned." Massive amounts of soap bubbles filled the washer. When we told him that the clothes that were washing at that time had been taken out of our clean clothes closet and were being washed without adding any soap to the wash he said that "someone" was using too much soap. I measured the amount of soap that my wife indicated that she had been using and determined that it was only 2 - 3 tablespoons of "HE-2X" Tide, the soap designed for front-load washers, in fact the same soap that Whirlpool shipped with the new washer. The repairman told us that we needed to use another brand of detegerent, we ask what would he recommend, he said, "Another brand."
So much for the repairman. Having spent twenty-five years working in industry as an electronics technician, servicing NC (numercial control), CNC (computer numerical controlled) equipment and working with PLC (programmable logic controller) technology, it just seemed the right thing to do to take over some of the control functions of the washer with a little of my own equipment. Having spent some time looking on the web for information on my washer (Whirlpool Duet GHW9150PW4) I found a service manual for a 9100PW0 and PW1 washer. The picture in the manual looked just like my washer, the only difference that I could see was mine was a 9150PW4 (the 4 ment revision four). Four should be better than 0 or 1, right? That's what I'm thinking. Well, after pulling the top off the washer I could see only one difference in my washer and the one pictured in the manual. My #4 revision and 50 numerically advanced model didn't have a water flow transducer like the ones pictured in the manual. Oh, the CCU, which is the computer brain box that controlls the washer, had a po



Ok, it was time to do something and get out of that laundry room. I never realized just how much work was involved in keeping clean clothes for the family and my wife had been doing it for years by herself without complaint. You can bet the next time she complains about some machine that she uses, not doing a good job, I won't ignore her. I'm still doing all the washing, but there is a light at the end of this tunnel. If I could control the OLE DUET with two ordinary powerstrips and sucessfully wash and rinse clothes, I could come up with some automated way to do it and get back to enjoying some TV.
It just so happened that hanging by the door in the man room was a little dev

This is my solution, not necessarily yours, but I decided to try and write this to hopefully get others to work on solutions to this and similar problems. I am using a small single chip based processor and board solution from Comfile Technology to monitor and control water levels in the washer and to have the ability to control draining of the water, allowing me to sucessfully wash and rinse a load of clothes without having to sit by the washer throughout the whole cycle. Remember the pressure transducer that I mentioned earlier, it has four functions: tank empty, Level 1, overfill, suds condition. The pressure transducer contains at least four sets of dry contacts that are used to signal the CCU in the DUET, indicating when there is no water in the tub, when there is water in the tub but not to the required level, when the desired water level has been reached and when there is a high-suds condition. This is all done with a single pneumatic connection to the lower side of the tank. The one function that I have not spent a lot of time trying to understand, how it works, is the high suds condition contact. If I'm in charge of the amount of soap used per load, this function should never be required. Thus, I have no need at this time to understand how it works, but it may be interesting sometime to try and understand this feature.
In order to accuratly control water level, I added the missing water flow trans

One thing that I don't know is how many models of the DUET will not do a good job cleaning clothes. If anyone with a DUET is having problems getting their clothing clean and soap free, please include the model number of your machine if you decide to comment on this blog. Just go to Google and type in "Whirlpool Duet and Stinky Towels," and see for yourself who's having problems. I've listed the link to this site.
Please people when you leave a post about your problem give us some specifics on your machine this will let us know if it is a single model that has problems or if all of the manufactures products are junk. Manufacture, Model, Model Number
My email address is ( joe.tass@yahoo.com ), I would love to hear about your machine and what you have done to solve the problem. I read a post by someone that said they wanted to load clothes in their washer, add detergent, hit the start button and walk away to do something else. This is what we are doing now, no special washes without clothes, no special additives, no problems!!! Just added water and problem was gone.
I would like to add at this time that I have just finished watching the 42nd Super Bowl (GO GIANTS) and washed a load of clothes without having to sit by the washer, there were two winners today!!! :)
I would like to get some pictures added to the blog but before I do this I would like

OK so I'm a little lazy, at least at this time I have put the top back on the washer, picked up my tools and cleaned the area up just a bit. No pictures at this time to prove it though. Now that I'm back to watching TV at night it's hard to want to get up and start working on packaging for the unit. If I'm ever to be completely free again it will have to happen. You'll notice in one of the pictures a couple of switches dangling from the dryer vent pipe, these will allow you to add either hot or cold water if needed, when adding bleach or fabric softner or even soap if you waited until the washer quit filling with water, waiting for a commercial!! I'm sure you want be able to see the short piece of wire attached to an I/O point in the lower lefthand corner, of the picture of the processor board. This will stop water flow by just touching it to one of the twenty-four volt lugs that you see daisy-chained in the picture (red wires). I tried to explain to my wife the other day, knowing about this wire is like knowing where the fire extinguisher is located, in case of fire!!! This is when she told me not to worry that I would be the only one that needed to know about that wire!!! Darn, not attached at the hip anymore but I still have a ball and chain to contend with for the time being. Looks like when the weather warms up it's going to be time to get out the ole saw and hammer and get started on that new control panel if I ever want to break free. Oh by the way the two white boxes mounted on the wall to the right of the washer are my tankless waterheaters, they provide all of the hotwater for the main part of our home, the kitchen has it's on small tank style unit. They do a great job for what I paid for them ( aprox. $250 each ) some years ago but I'm thinking that I can improve on them with some new technology, this may be one of my next blogs. Either the hot waterheaters or with spring coming on maybe the ole home built zero turn radius hydrastatic mower will be next. OK I've got to get back to work so that's it for now.
Here is the link to the repair manual for the 9100/9200 series Duet ( http://adcxns1.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/eab852a13fbc842085256aa200643dd6/$FILE/Duet%20Job%20Aid.pdf ). If anyone is trying to work on their own washer this manual should help. You'll find a schematic for the unit at the end of the manual, this really help me determine the correct connections to the CCU that I needed to make my control system be able to monitor and control the water level in the washer. I think you'll find it i

Here is a link to a great site for repair parts and advice. ( http://www.repairclinic.com/0046.asp )
This is a link to a tech manual for I think a Kenmore machine, a Whirlpool clone. ( http://www.servicematters.com/docs/wiring/Tech%20Sheet%20-%208182208.pdf )
This link takes you to the Whirlpool instructions on how to clean your washer and get rid of the mold smell. ( https://secured.whirlpool.com/Service/SrvTechAdm.nsf/a9c27c267a3fa32785256a45005190c7/4f0b8f4a368dc937852570a00070cd1f/$FILE/UD28-9.pdf )
This is an on going project as I have time I will add specifics, part numbers, pictures and links when available.
Good News
I hope to have good news to add to the blog soon. My sister is coming tomorrow to spend a couple of days with us and if you remember she is the reason that this crises came to a head in the first place. She had told my wife that she was unable to use our towels because they smelled bad. This was not good for me because I had been trying to ignore the problem because I knew it would mean ethier spend a lot of money that I didn't have to spend or it ment spending a lot of time trying to solve the problem. You guessed it I chose the latter. Tomorrow I will put all of my work to the ultimate test when my sister inspects our laundary. May the force be with me!
This whole process could be so simple if we could get the word back to Whirlpool and hope that they would respond by suppling their repair techs with the parts required to make their product do what it should have done before it was ever offered for sell. Just supply us with recalibrated pressure trasducers, add flow meters to those models where they were left off and upgrade the CCU firmware to work with these new parts.
Water Water every where and this could help get some of it in the washer to clean your cloths.
You know a creative guy could solve this water problem by going to RED LION CONTROL and purchasing a programmable timer and using a double pole double throw relay (120vac) to make a set/reset function to select hot or cold water. With just a little expermenting to determine the time required to fill the washer to a functioning level with water, letting the hot water signal from the CCU set the relay to direct the output of the timer module to control the hotwater valve and then when the washer calls for cold water use this signal to reset the control relay allowing the timer output to be directed to the cold water valve. This could help someone salvage an other wise useless appliance. Oh use the hot and cold water signals from the CCU to start the timer when the washer is calling for water!!!
***Be sure to take a look at my other post, Mike's Duet (look under my profile section for additional post). Mike solved the problem by resetting the water level function on the pressure switch. It only takes a small screwdriver and a little time!!!
Thats what I'm talking about. Great job, Mike. I'm sure this will really help some folks out with their machines with no expense involved!
Please see my other post by viewing my profile (View my complete profile ). You will find this at the top left corner of my blog, Rebirth of the Ole Duet. GOOD LUCK! I've started posting emails in the comment section of my blog, at the bottom of the blog. Check it out and let's us hear about any success stories.
Email me with your results at (joe.tass@yahoo.com) Remember to include the machine name, model number. This will help others. If you have a link to schematics to your machine, please include it with your email. Thanks
See- ya again soon.
