I can answer a couple of your questions.

1) The advantage of having a Sanitize cycle is that the washer has an internal water heater. My Maytag (made by Whirlpool) heats the water in the Sanitize and Allergen cycles. I think it also boosts the temp a bit in the PowerWash cycle when choosing the Extra Hot temperature setting.

2) Are models with internal water heaters good? I certainly think so. I don't always use cycles that boost the water temperature, but the option to do so is there.

thank you for your answer doing research so don't went to make the same mistake as 2005 because my actual duet washer has no internal water heater

One of the benefits of having an on board heater, some MFG can do profile washes that gradually heat the water to temp for better stain removal.

Two, if any members of the family is sick (flu), this will help slow the spread of the germs if bleach is not used.

The boost is a plus but not necessary if the water heater is cranked up to the highest heating setting but with some energy saving machines, they may have dumb down the temps and add cold water if water is too hot. The manual should state if hot water is straight from tap or blended!

One benefit is that a washer with a true sanitize cycle can typically sustain 60C which is the temp needed for killing pathogens.

Without the ability to heat to this level one must use bleach to kill the germs which is quite hard on the material vs hot water.

Wife is a pet groomer and we have a load a day of nasty towels from pet grooming.

Our Frigidaire 1-18 from the early 70s had a sanitize setting at the rinse portion of the normal cycle. The instructions were to use the lowest water level, add a cup of bleach and start the machine. Given the way normal agitation would throw water at the minimum fill setting, it was almost like a dishwasher inside so I think everything got exposed to the chlorine solution. It was supposed to sanitize the washer after washing a particularly dirty load of laundry, or if you were using cold water washing and the machine turned into a science experiment. I don't know how well it worked because we always practiced hygienic laundering, washing things that needed it in hot water, but that was the first I recall a "sanitize" setting on a washer.

Per a discussion in the Gardenweb laundry forum a while ago, a sanitize cycle on current washers is not a guarantee of high temperature.

While our Whirlpool Duet doesn't have a heater.

It does feature "Sanitize with Oxi" cycle.

The cycle uses straight up hot water from the water heater and uses A LOT more water too.

After about 10-15 minutes into the wash, the washer fills up with more water. At this point there's serious wash action and that continues until the first drain.

Our Samsung built Kenmore steam dryer also has a sanitize cycle however I tend to not use it as I feel like the dry, hot heat will eventually damage fabrics. However I do find this dryer DOES in fact run cooler than our old Maytag top mount lint dryer on the normal cycle.

thank you washer dude right now i am doing research and reading up and the reason i was looking into a model with sanitize cycle is in case of cold or the flu that way with that cycle i could kill the germs that are on bedding or if i have smelly rags to wash

Pierre, I apologize for not being able to respond until now.  My 2011 Whirlpool Duet (and corresponding Maytag Maximas) were the last generation of Duets and Maximas to offer both NSF P172 certified Sanitize and NSF P351 certified Allergen cycles.  P172 means water temperature will reach 153-158 degrees F and P351 means 131 degrees F for 3 minutes or so.  The next generation offered P351 certification but P172 for Sanitize cycle was no longer provided.  Maytag's current MHW8150, MHW8200, and MHW5500 are the only whirlpool produced products offering Allergen P351 certification.  The importance of a P351 certified Allergen cycle means that a certain level of hot water temperature is almost assured.  I use sanitize high temperatures about once a month or so on my Allergen cycle with steam for stains option for my terry cloth napkins and kitchen cloths that have food stains and such.  I'm fortunate my model has several cycles where the heater comes on to maintain or slightly boost water temperatures for both warm or hot that offer both fast or medium speed tumbling.  Selecting heavy soil level allows for longer wash times to allow longer heating time. I haven't used liquid chlorine bleach since I bought this washer November 2011.   I'm actually very disappointed Whirlpool removed Allergen cycles from their current model line up associated with this last generation.  I know why they did it, to meet Energy Star guidelines.  But why couldn't they still do it--some of their competitors still managed.  Current models offer "Extra Hot" temperature but it's not the same--especially considering all hot and warm water temperatures have been dumbed down again.  At least current Maytags still offers the Allergen cycle feature.  It will be interesting to see what the new lineup will look like meeting new 2018 Energy Star restrictions.  I'm hoping Whirlpool related products will offer models with downloadable cycles capability to offer more than the standard cycle offering--one of their latest dishwashers offers this feature.

Given the variables involved

One should take note of how nurses clean.
First, remove the large-scale dirt. That means hot enough water, good detergent (a washer with a program to run up the temperature to maximize enzymatic action is a gigantic plus here) and enough water to actually do something.
Second, kill the germs and eliminate those allergens which survived the first cleaning. That means oxygen or chlorine bleaches, thorough rinsing (again, this means enough water) and, finally:
No sticky/waxy fabric softeners in the washer and none of those horrid dryer sheets in the dryer. No scented detergents.
And, of course, a clean washer - which is another aspect of the 'sanitize' function. Now that people foolishly expect cold water to clean clothes (it doesn't) and washers use too little water, it's a must to regularly run the machine's own clean/sanitize cycle.
As to Whirlpool/Maytag - Bob already covered what matters right above this comment. In terms of quality, Maytag is really nothing but a gussied up Roper/Estate, so the only reason to buy one is because it meets the sanitation standards you need. Otherwise, it's just a spending more money than necessary to have the pretty label.

At what point

mark_wpduet's profile picture
does Whirlpool introduce new models? Is this something that usually happens every year? I only ask because it seems like they've been the same for a couple of years.

Mark, it depends upon what it is.  Mark, the new TOL dishwasher, that is now above Murando's model, was introduced this past spring.  The new TOL front loaders were announced January or March 2016.  Within the last few months, a new compact front load pair, with a control panel like their TOL Cabrio was introduced last fall maybe.  It's ongoing.  With this new control panel for a front loader, I'm expecting an update, just have no idea when that will happen.

Bob, I bought a copy of NSF P172, in secured PDF form, so I could see what it really says. It doesn't require the washer to reach any particular temperature. It was last revised in 2006, so this isn't a new thing.
