Do Dishwashers Heat Water?

Do dishwashers heat the water, or is the element in the bottom
only used for drying?

IOW, is the element on when water is polled in the bottom of the
washer?

To quote from my manual:

Hi-Temp Wash increases the target water tem during
the wash portions of the cycle to 145.

polled?

Ours will heat the water up to temperature if the hot water is not hot
enough as it comes in.

Some people recommend that this is the more economical way to wash dishes,
rather than keeping your hot water heater at a higher temperature 24/7.

Actually, my manual spells out the words, I shortened
temperature to tem. Lazy finger.

Mine will also.

I just opened up my dishwasher while it was washing and noticed
the element sits above the pool of water, so it would seem to be
an inefficient way to heat water.

I was tempted to touch the element to see if it was hot, but I
hadn't had enough beer yet today.

Maybe your water level/pressure needs adjusting?

Or maybe the heating of water is done elsewhere other than the drying
element? Or perhaps his doesn't heat the water at all? Older models
didn't.....

I would guess that most of the water in the pool is airborne at any
given instant while the dishwasher is running, some of it hitting the
heating element after leaving the spray arm and/or on the way back from
elsewhere in the cabinet. This could be enough to heat cooler water and
maintain already hot water during the wash cycles.

Perhaps once you've had enough beer you could disable the door
interlocks and observe this action first hand, with the door open. If
you do choose to touch the element at that point, you'll probably want
to wet your finger beforehand, if it isn't already sufficiently wet.

Hope this helps,

That might not be much of a boost, depending. My hot water from the tap
is 130F.

No, it's clear that his *beer* level needs adjusting.

The idea is who needs water that hot coming from their tap, so
you could lower the setting on your water heater. I don't either.

I could put my little brother in there and tell him to get a
first-hand report.

I didn't think about it until after the wash cycle was through,
but I could have just touched my Polder/Taylor remote probe to it
for a few seconds.

It is pretty steamy when you open the door, so that would tend to
suggest the element is on and water hitting it is producing
steam. Most washers work at 150F or below, and that alone
wouldn't generate much steam.

As somebody mentioned, that water is swishing around in there
being recycled for the length of each cycle. I suspect it would
cool down pretty fast, so something needs to maintain the heat of
the water.

Apartment building. And we do need it that hot, for this reason. The
hot supply (as in "amount of hot water available") isn't barely adequate
to go around, and varies considerably as other people use it. So when
you're in the shower, it can get cold - depending on total demand at the
moment. If what hot water we *do* have is quite hot, it doesn't take
much increase to make the blend comfortable. But if it's *not* quite
hot, then it takes *more* hot water to get the blend up to speed, and
that *adds more to the drain on the supply because*. At one bottom end
of the extreme, and we've been there with managment that has turned
*down* the water temp, even with the hot tap full open there's not
enough to take a shower because the volume of the hot flow is so low
that by the time you add in enough cold flow to make the showerhead do
anything but dribble a pee-stream <g>, the blend is too cold to use.

So, what I think you're saying is you flat out lied about your water
being 130?

Heh. nancy

At least in Switzerland and in France, they do - they're almost always
connected to the cold water supply.
