I have a whole house water softner What kind of miele dishwasher?
Comments (10)I had my Miele Excella DW bypass our whole house softener and had it connected to the COLD water supply. Why? Long story short, TOO soft water and/or too HOT water can permanently etch your glassware. I learned this the hard way. The Miele DW softener supposedly reduces your water's hardness to about 5 grains of hardness, which is supposed to be optimal for use with today's DW detergents. A whole house softener will reduce it to zero grains of hardness. The detergents are too harsh in zero hardness and permanently etch glassware. Glassware is supposed to be washed in less hot water than a normal household water heater sends in the hot water supply. Therefore, I let my DW heat the wash water to the proper temp for each wash cycle setting. I wash my glasses in a seperate cycle setting "Crystal/China". I have two DW, so this is my luxury and so far it is saving my glassware, including crystal wine glasses and my "good" china! Having to heat the wash water causes my DW cycles to run a bit longer, but my dishes are being washed as optimally as Miele technology knows how to do!...See MoreFinal Decision: Miele DW - hot or cold water hookup?
Comments (13)I think many cycles on my DW use about 4.2 gallons of water or less depending on soil and load size but the DW can use more if the soil level is high but no more than 6 gallons. I connect mine to hot water, however my DW is not close to the water heater so the actual water is not all that hot, but better than the 38F degree water that comes out of the cold water line in the winter. I don't wash fine china in the DW so don't really care about dish damage, but even if I did because of my situation I can still get a cooler fill for that cycle. So it depends on your situation. If I cared about the china crystal thing ALOT then I would go with the cold water supply. Since I don't I opt for the hot water supply which helps speed up the cycle a little. I have seen times where there is a temp delay using a hot fill (you can tell if the time remaining count down stops and holds the same time) The delay has never been more than 3 minutes and then the time countdown will resume, however this will only happen if there is some different unexpected condition because each time you run a cycle the DW will take the time it took to heat the water into consideration so that the next time you run that cycle the initial cycle time will already include the time it took to heat the water the last few times you ran that cycle. Anyway it depends on your situation. For me no worries about china/crystal = hot water fill....See Moreconnecting Miele dishwasher to Cold water only. x-posted
Comments (7)Your sales weasel is prob. just ignorant but might just be an idiot. Almost all DW's in Germany are hooked up to cold water. Miele's are very well engineered and will heat their own water just fine without reducing their life span. Tell him to read the operation manual which advocates a COLD water hookup for their DW's that have a China & Crystal setting. The wash times will be extended but "greatly" ???? Don't know about that. AT 2 hrs long for a cycle, what is another 20 mins? It's not like you sit around waiting for it to finish before you go to bed or start lunch. If you have a china/crystal setting and plan to use it then hookup to cold water, if not hot will work fine too. regarding efficiency, the calculations are fairly mind numbing but where I've done them electricity is almost always cheaper per BTU when heating water. The only place this doesn't seem to hold is in New England which has sky high elect. rates....See MoreIs hot water needed for dishwasher, or does it heat cold water?
Comments (31)you’re either referring to the law (in Washington State, anyway) regarding rental properties, or you live in some place that has uber nanny legislators. And seriously? YOU don’t think YOU are smart enough to know what temperature YOU want YOUR hot water in your home? Any who, I don’t want the dishwasher to turn the electrical heating element on. Electricity (unless your using magnetic induction) is an inefficient way to heat water. It is better for my house to use hot water from my tankless HWH. I have a tankless HWH that will produce 190° hot water if I set it correctly. I have a dedicated line from the manifold that natal led between the heater and the Case Acme temperature regulator. I send 160° water to my dishwasher, and washing machine. (I also have a dedicated line that supplies 160° to a separate faucet on my sink that takes the place of the under sink contraption that crapped out a while back. (120° is the legal limit? Don’t tell InSinkerator. I doubt those gadgets they make can even go down to 120°.) I would use 180° water but I am afraid the water temperature alone might melt some plastic ware and also damage some synthetic fabrics. Here’s a thought, when it comes to how YOU choose to live in YOUR house, man up, and grow a pair....See Moreasolo
