Re: [DIY] Re: No hot water in dishwasher/ water temp calcs

 

I am baffled about this, too.  Does the line to the DW run inside the cabinet from sink to DW?  The water in that line (probably 1/4" copper or flex) is going to be @ room temp., not 50 degrees. There is no connection of the cold water line to the DW.

On a job of mine today (I am not the plumber), they capped off the water lines to the sink and DW, then all other faucets were running hot to both cold and hot faucets.  Sure made me think of this thread.

P.S.:  I hate that computer keyboards do not have a degree symbol key.

Terry, this formula sounds correct and if this is the problem, I don't see any way to ever get hot water into the DW in time to dissolve the detergent (and get clean dishes) - short of running a light cycle first, 50 minutes with no dry, or running the heavy soil cycle, almost 2 hours and wasting lots of water.  If I use the heat water choice, it adds another hours to the cycle and no idea how much energy to heat the water.  So much for paying extra for an energy saving device :) GE recommends and I prefer to use, the packets.  No big bottle of liquid to store, no drips, no measuring.


Our cold water is about 50 degrees, faucet at least 130 — so that probably accounts for the first fill at 80 degrees — but I still have a hard time believing there is over a gal of cold water in the line.  It is at most 3.5- 4', laid out.  Extends from the connection on the right side of cabinet, across the back and comes up under the DW and connects near the left side.  If I unhooked this line and filled it with water I don't think it would hold 16oz.

Water and Air Temps are Proportional, e.g. 1-gallon 100'f water mixed with 1-gal 50'f water will give =75-deg water; 

(another) I-gal. @140-deg + 1/2-gal @40-deg= 106-deg (if my math is right) 
Note the 40-deg= 33% of 1-1/2-gal total volume (so math is (66%x 140-deg)+(33%x40-deg) = 92.4+ 13.2= 105.6-degrees

Maybe you are onto something there...???

The winter changes, I believe, are why DW have heaters to reheat the water if too cold, before starting cycle.  (recalling my old Maytag), you can turn it OFF w/ control switch/ button in summer, or if using soap that works w/ cold
