As I put a dish into the dishwasher I thought to myself, “🤔 I haven’t cleaned the filter in a while.” So I took it out and gave it a real good blast with piping hot water from the kitchen sink. I even scraped some of the gunk off with a dish brush to the point where I couldn’t find a single mote of gunk upon careful examination.
Then I proceeded to refill the rinse aid (even though it wasn’t empty) and–as usual–spilled that stuff all over the interior door in the process. Is it even possible to not spill the rinse aid when refilling it? 🤔
My journey didn’t end there, however! I then proceeded to walk the entirety of my home searching for cups and plates that may have been left behind by my children, found several, and it was enough that it nearly filled the dishwasher racks; bottom and top.
The dishwasher has been started; the wait begins.
I have never seen a dishwasher that doesn’t heat its own water, and I have seen many. Is that a thing?
They have an element for the dry cycle and often want water hotter than they will get from the tap so the ones I’ve seen heat their own water. Running the hot tap first wouldn’t help in that case.
They exist (my godmother had one) but it is really a niche.
Does it have a dry cycle still? If you are putting in an element you might as well heat the water with it.
Sorry, no idea 🙂
I don’t think that changes anything. You still want to start from hot water so it has less work to do heating it.
Then again, my water heater is in the basement right under the kitchen so water gets hot fast, and I don’t bother
My dishwasher (and every dishwasher I’ve had or seen) is not even connected to the hot water.
What part of the world are you from? In the US, every dishwasher I’ve seen is connected to hot. If I google it, almost all results say it’s connected to hot, with a couple exceptions mentioning cold water dishwashers. Also that technically it will work but at higher cost and reduced life expectancy
Very interesting! I’m in New Zealand, but the dishwashers are largely global brands like Miele, Bosch, Samsung, LG, etc.
There is no reason they couldn’t be connected to the hot tap. It’s normally connected next to the sink. I have just never seen it done!
The reason I always heard was that it’s generally more cost effective to let your water heater supply hot water than to rely on the heating element in the washer. Most US dishwashers are plumbed to the hot water, so you’re already paying to heat that water, may as well let it make it to the dishwasher instead of just cooling off in the pipes.
It also makes the initial rinse cycle that much more effective.
I doubt it adds up to appreciable cost savings, but it’s just part of the routine at this point.
