Hi Temp Boost

[atomranch]

I have a quick question:

I just bought a new dishwasher (Whirlpool) and was wondering how the "High Temp Boost" was achieved. Does the drying element stay on during the wash? Or is the boost achieved through some other means? Also, how much of a temperature boost is achieved using this option.

Just curious.

Thx.

The heating element is used

The heating element is used for drying and for water heating. 

 

Older electro-mechanical control models typically had 1 thermostat setting (140 / 145 / 150 degrees F were some of the most common).  The cycle timer would pause and the heating element would be energized until the thermostat registered the temperature setpoint.

 

On newer electronic machines, the temperature setpoint is cycle dependent.  I have not looked at Whirlpool literature as of late, but assuming it is programmed like its sister Kitchenaid dishwasher that I have , the added heat temperature setpoint is cycle dependent.  For example, the hottest water temeprature by default is set automatically when the 1 hour was is selected (the unit will not allow you to select the added heat option).  This temperature setpoint is 140 or 145 F.  The normal wash with out the heat option is 120 F and with heat is 130 F.  Please forgive me if I am a few degrees off on my settings - I am typing this at work and doing it from memory as opposed to having my literature in front of me.

THE SPECS ARE THERE...

Sometimes the cycle specs are in your owner's manual but if you remove the door panel or look under the machine there is usually a technician's technical service sheet which describes in detail how the programs work and what each one looks for in order to progress thru the cycle. It may describe how on a certain setting, the computer will check initial fill temps and then monitor how long it takes to reach a setpoint and if it does, it progresses, and if it doesnt, it may default out at say, 10 minutes of heating and if the set point is not met by then, it will then advance to the next phase.It will also measure how much water it sees and will flash error codes thru the panel lights or in the display if there is one. It is actually pretty good reading if you really want to know what is going on.

It will also go into the soil levels and how the machine may drain and purge to insure clean water and dishes. The machines with the optical sensors work so much better than the ones which used the water pressure switches to measure soil levels. "Seeing" how dirty the water is will tell the computer to alter the program for proper results adding time, heat and or water. If the water is cleaner and hotter, it will speed things up a bit and will sometimes use a greater portion of the prewash water for the main wash.. You could almost say that no two complete cycles are exactly the same on the computerized machines.
Lots of good stuff there!

I read some service literature years ago (when servicematters.com was still open to everyone) and it indicated that Hi Temp would *boost* the temp from 105F to 120F.

me i have a kenmore elite dishwasher electronique control even do i use the smartwash cycle on my dishwasher and use the turbozone option for optimal wash i have to have the hitemp option on (*not the sanitize rinse option) or my dishewasher would wash in half cold or warm water since its full electronique and sense the load as it wash including a pic of my dishwasher model. Sorry if the picture is blurry

Thanks for the info

Thanks everyone for the information.
The model I purchased (DU850swpb) has electro mechanical controls. (No digital readout and has a rotary selector) I was trying to stay away from the electronic controls after reading about potential fires from the control panel area on the dishwashers that have electronic controls. 140 degrees sounds good. I will have give it a try.

Thanks again.

high-temp wash

My Whirlpool Gold dishwasher will change the amount of time when this option is selected. For example, the normal cycle with high-temp wash will start draining at 75 minutes. Without it, it will say 92 minutes if I am not mistaken.

Random tid-bit:

I had a GE purchased in 2011. sorry, I don't have model number.

One time the water heater failed. Out of curiosity I set the dishwasher to the shortest sanitize cycle (the usual) and let it run.

The cycle took about an hour (IIRC) longer than usual, but it ran. I had no themometer, but I opened the door several times and each time the water seemed as hot did normally. The "sanitized" light was on when the cycle finished.

I wonder if this is the usual or not. Maybe the heater ran until proper temp was reached only because a sanitize cycle was set?
