If you filled half your dishwasher with ice cubes and ran a cycle, how much of the ice would remain when the cycle is done?

I would guess that no ice would remain.

My guess is one of two things are most likely, depending on the machine and its condition.

Either:

1) The ice all melts. (Dishwashers tend to apply a lot of very hot water. More than enough, I think, to melt a half dishwasher-full of ice cubes.
or
2) The ice messes up the operation of the machine, which breaks down or aborts the cycle. (Dishwashers are not designed to handle being filled with something, and tend to be designed to stop if there’s any kind of problem detected. I think the expected water flow would be interfered with, and I think that may very likely cause the machine to abort the cycle.)

Probably no ice. I think don’t ever try it. It’s a lot of extra water, and I don’t know how the dishwasher gauges how much water is in it. If you open a dishwasher mid-cycle it isn’t full of water, the water is just at the bottom.

According to this calculator: https://www.engineeringtoolbox.com/mixing-fluids-temperature-mass-d_1785.html
my mini dishwasher with a capacity of 30 litres, and filled up with 15 litres of ice, using 2 litres of 70 degree hot water, would result in 17 litres of 0.3 degree cold water, assuming the ice started at -9 degrees, and the dishwasher is not heating the water at all after the initial heating to 70 degrees.
And since the dishwasher is definitely heating the water during the washing procedure, the result will definitely be warmer than that.
So, no ice will remain at the end of the cycle, if the cycle is long enough.

There would be water all over the floor.

BAD THINGS WOULD HAPPEN.

@Tropical_Willie why? Wouldn’t the drain pump relay click on and empty the inside of the dishwasher? Not sure why there would be leakage from a sealed cube.

@Blackwater_Park thank you for the well-thought-out, detailed, and incisive reply.

Drain relay is on a timer, water add is stopped by a a float level.

Float failed on 4 year old dishwasher and poured water all over the hardwood floor in the kitchen.

There a door seal to keep splashing water in but water ;level got high enough to push past gasket.

Perhaps the best way to obtain a solid answer would be to induce the fine fellows who made this video to conduct an experiment.

Though, I maintain the results may vary on a per-dishwasher basis (and perhaps in some cases, also with the settings used).

@elbanditoroso The sprayer that rotates would get jammed up and probably fry the motor. The drain would be at least partially plugged and potentially cause water to flood your kitchen. This is in addition to the melting ice that will cause more water than the washer can handle. Depending on the safety failsafes built into the design, I would hope the initial overcurrent on the rotating sprayer would shut down the washer, but I would not bet on it. Perhaps there are other sensors that will shut it down but no matter what, you’ll have a kitchen full of water to deal with.

It wouldn’t run. Nothing would rotate if it was half in ice and sealed.

I agree most likely water everywhere. If you put regular dish soap instead of dishwasher soap in the little soap place thingy, just that small thing you will have bubbles coming out through the dishwasher door if you run the cycle.
