What did Whirlpool tell you about this? I called and was told that "no changes were made to the duet sport ht except for the knob." Do you have some sort of part number or something that you can provide that I can use when I call them back?

Thanks

Everything I wrote above is true. No answers other than "If It Is Not In The Book, You Don't Have That Feature" . Bottom line my new CCU is on it's way. Once its in, the washer will heat on hot Heavy and hot Whitest Whites. It already works on Sanitary. What does your book say? If you have the 2/06 manual then test it on a hot fill on Heavy first cycle of the day. When it drains its not heated. It is to be 140 degrees and im giving it 120 best effort. Luke warm. Water level is less currently too so I'm looking forward to the new CCU.

northwoods, I'm going to check my manual tonight, although I have the Kenmore version, not the Whirlpool version. Question, how did you test the water temperature (by feel or with a thermometer?)

I have no doubt that everything you said is true. I also have the 2/06 manual that leaves out the water heating info. After seeing one of your posts, I called Whirlpool to ask about what was going on and they claim that the info was just left out of the manual. I referenced the info in your posts (they kept asking where I got the info and I decided not to tell them...I suspect they try to dismiss anything said on forum like this one) The story I received from them was that there have been no changes to the machines expect for the control knob. Did the store you bought it from provide you with the updated CCU info or did whirlpool? I'm wondering if I called back and spoke to a different person if I would get a different answer or if I had some additional information that I could say to them.

BTW, has anyone tried the clean washer setting yet? My machine leaked quite a bit (doesn't on any other setting), repair has been scheduled.

I scheduled a service call due to not heating on those cycles mentioned. Result a new CCU on order.

Northwoods, how did you KNOW it wasn't heating on those cycles?

Can somebody tell me what CCU is??? I purchased the Whirlpool Duet 9400 model August '06 which has heavy duty, whitest whites, and sanitary cycle. My manual has 11/05 on back page bottom right hand corner. What does this mean for moi?? Help somebuddies!!!

dm I checked by draining water into a bucket after the wash cycles...not heated.

Well folks I called the technicians line and he put me through to someone to give this issue a rest. Im ticked at this point and yep folks the washer was changed and Whirlpool refused to narrow it down to what specifically other than the heater added to the heavy/whitest whites cycles and when bleach dispenses. Would not say new CCU would work or not. To boot...I quote!! ... "We will not pay to change the washer so it does heat" . I ain't payin for it I tell you...Cheers

I finally read what it says in the manual for my HE2T (the equivalent of the 8500). The paragraph after "Spin Speeds" is "Thermal Optimizer" and it says "The heating system ensures that the wash water is heated to the preset temperature for Heavy Duty, Whitest Whites, and Sanitary cycles. It also provides "Stepped Cleaning" when using the sanitary cycle. ...."

I guess that's what it's supposed to say/do?

Yep dm...looks as if your model is ok.

melikey what action are you going to take? e-mail me from this point out and I will respond from there.

The fact is this washer has been changed very early in production. For Whirlpool not to change the model and serial showing this difference is a sneaky deal. Can you imagine trying to buy the right one as of now. Be sure to ask that sales person to slice right through the plastic and open the door to retrieve the manual...2/06 no heater heavy/whitest white, 3/06 you have heat heavy/whitest white. LOL on my sales person comment...I need to perk up I guess. Whirlpool you read this!! Lawyer if you fight on repair all I can say.

Northwoods....something must be wrong with your machine.

I have the 8500 duet sport, got it the beginning of November. My manual has 2/06 on the bottom right hand corner on the back page, does NOT have the "heating element" paragraph on page 11 and my heater WORKS on the whitest white, heavy duty and of course the sanitary cycles. I ran a load of towels on the heavy duty cycle this afternoon just to double check. I was in the laundry room right next to it ironing for the first 45 minutes of the cycle. The wash time is 39 minutes on this particular cycle the whole 39 minutes the wash never brought in any extra water.....my first clue to the heater must be working. I kept feeling the glass on the door which was warm to the touch, also I kept opening the dispenser door and putting my fingers all the way to the back of it, I could feel the steam/humidity and heat coming from in there. Then when the wash cycle was done and the machine drained the wash water I held the plastic drain pipe and it was warm almost hot.

I am certain that the heater works on the whitest whites cycle also, but I will double check it later this week.

I'm not to sure where you got this information about the heater not working on the whitest whites and heavy duty cylces, but it's not true. I really hate to see this false imformation getting started about the 8500 sport. The 8500 sport is a very nice machine! I really love mine! And NO my pump isn't noisey and NO I don't have any vibration issues with it. And YES my heater works in all 3 cycles.....whitest whites, heavy duty and sanitary.

BTW....it cleans very well too!

What temp is your hot water before entering the machine? If its above 120 then it will be hard to test this out. Try draining wash water into a bucket and then check. My information came directly from Whirlpool and from those who know. The washer was changed as I said. This is not misinformation fyi. Cheers

I still don't think this is true...Because, as I said the wash time on the heavy duty cycle is 39 minutes and at no time during the wash did the machine bring any extra water into the drum besides the intitial fill at the very beginning when I started the machine. There is no way in the world that after 39 minutes the door would feel warm, nor would I have been able to feel the steam/humidity and heat in the dispenser drawer, nor would the drain hose have felt very warm when the water was drained going into the first spin/rinse cylce. Doesn't make any difference what the temp of my water was before entering the machine, even if it was 120 it still would have cool off enough in 39 minutes that the drain hose wouldn't have felt very warm when it drain the wash water.

The Heavy cycle is 87 minutes total. What does bringing in extra water or not have to do with this? The water would not have been cooled off in the wash...it would have drained at 140 if it were working. Anybody else other than frankie57 please post your results please. Better yet frankie57...cooperate with me and test it as I have posted. It would be appreciated!! BTW the temp of your water at the water heater does make a difference in this and it would be in your interest to test it as I posted. Cheers

I'm sorry, I didn't make that clear on my last post....the total time for the heavy duty cycle is 87 minutes, but the wash time on the heavy duty cycle is 39 minutes. What I meant about bringing extra water in was.....if the wash time is 39 minutes there is no way that the water could have stayed that warm for 39 minutes if the washer didn't bring hot tap water or in during the 39 minutes. That's what made me say that the heater had to have been working and heating the water during that 39 minutes.

I just got off the phone from Whirlpool, told her I wanted to know if the heater my 8500 was used in the heavy duty and whitest white cycles. She read the page 11 paragraph "heating element" off the manual from their website. I then told her that my manual didn't have that parapraph and told her I'd heard that there were supposedly two different manuals. One with 2/06 which I had and one with 3/06 which has the "heating element" paragraph in it. She put me on hold for over 25 minutes to have the correct person check into these issues. I was told that there were no changes to the heatter on the 8500 sport that it works on sanitary, whitest whites and heavy duty. The deal with the manual seems to be, whirlpool updates their manuals often, the 8500 was update to add information for customer clarification, heating element was one of them.

I don't know why Whirlpool would lie about this, and the gal I talked to on the phone put a lot of effort into checking into this for me. But, since I feel like I've upset Northwoods and I don't mean to be difficult, out of curiousity I'll test my next heavy duty drain water in a bucket.

As far as the changes in the manual go (and I'm not commenting on the reality - the machine may or may not heat in the modes northwoods refers to), keep in mind that the 8300 came out first, and the 8500 several months later. One of the main differences between the two is the internal heater. It's not at all surprising to me that some earlier versions of the 8500 may have been shipped with a manual that left out that information, even if the machine performs properly.

Update on this...Still waiting on CCU and when it gets here I will check the software version between the old one and new one. Anybody else to confirm my findings yet? Cheers

I think that most whirlpool/Kenmore made washers heat the water the same way. My 3 year old HE3t, predecessor to the HE4t/HE5t, with the stain treat option on (the default for the Heavy Duty cycle), fills with warm water. Then the heater comes on, and heats the water to 127F. Once that temp is reached, the heater turns off, and does not come on for the rest of the wash cycle. Depending on the size of the load and the soil level setting, there could be 5 or more minutes left in the wash. By the time the washer drains, the water could have cooled off considerably.

The best way to measure water temp is to use an instant read thermometer. Just open the door after the fill completes and measure the water temp. Do it again about 10 minutes later, and see if the temp has risen or fallen. Once the water temp passes 120F, the door no longer unlocks when the cycle is paused. The heater can raise the water temp about 1 degree F per minute, depending on load size and room temperature. Sometimes faster, sometimes a bit slower.

Here is the routine on my washer for the HD and WW cycles, hot temp, stain treat option off, heavy soil option.

1. Washer fills
2. One minute after the end of the fill, the heater turns on. I hear a click and see the drum rotation pause for a moment.
3. Heater stays on for up to 16 minutes.
4. Heater is off for last 5 minutes of wash cycle, even if target temp is not reached.
5. If wash water temp is over 122F at end of wash cycle, cold water is added before draining.
Total wash time is 22 minutes, plus fill time.

Can you hear a click when the heater engages/disengages on the newer machines? If I press pause when the heater is on, I hear it click off.

Joe the machine you have is different. I have seen a Duet Sport 8500 with the manual 3/06 and the heater boosts to 140 degrees as do everyones with that feature. The facts will come out soon on this and as unimportant this is to most here, is important to me. I phoned the technicians line and explained this and was put through to somebody who knew the exact details of this issue. The washer was changed early on. Yes my machine works as the manual says and then Whirlpool changed the 8500. Calling the 1-800-253-1301 number will get you nowhere! I swear by this and its unfortunate that most get the same ol answer. Fact is those with the 2/06 manual do not have this feature and only a Sanitary cycle that heats. Enough of debates and I have yet to see anybody here disprove my findings...but it would be nice for those who have this same version of the 8500 to state the fact! I will not settle on this period and it will be fixed. Also in addition to the CCU ordered is a new temp sensor. Im not sure that was needed but when its fixed I will post again. How Whirlpool deals with this will be interesting and I feel those who have this specific issue will soon be excluded from repair. Cheers

I hope you get this worked out.

I have found that sometimes manuals and machines don't always match exactly. Have you taken temperature readings to verify that indeed the wash water is not being heated on the heavy duty and whitest white cycles?

Where did you read that the heater boosts to 140? I have not seen any other temperature specs other than when the first version of the HE3t came out. I would be interested in learning more about the current specifications.

My HE3t has the following temps:

Tap - Tap cold
77F (25C) - Cold
104F (40C) - Warm
122F (50C) - Hot (Normal Cycle)
127F (53C) - Hot (Other Cycles)
153 (67C) - Extra Hot (Sanitary Only)

sorry to dredge an slighlty old topic but was this ever resolved? if there are two versions on the market is anyone still getting the older one?
