I'll give you my thoughts based on what I have read and my experience with my prior Miele DW purchased in 1996 and my current LaPerla purchased in 2006(Kitchen remodel), so this is not to be taken as "official" Miele speak. All of the models use condensation type drying, however most of the models also use a technique that uses a fan which makes the drying better. The Advanta does not use a fan. It just sits there - thus the phrase passive - it does nothing to help things along. You can open the door and that might help it a bit. The other models use the fan technique, speeding the drying and helping to remove the moisture better. The inspira, Optima and all the models up the line use the fan. I don't think etching is unique to Miele DW because almost every detergent and rinse aid now claims to have some etch protection agent in it. Soft water combined with higher temps can speed the process. Some of the programs on the Miele DW use HOT water. You can connect it to cold water if you want to because it will heat it to the required temperature. Pots and Pans is around 168F to 170F, Sani cycle is also this hot. Heavy Soil is 150F. There is a program named Normal which is designed to clean most loads. I think it's temp is 130F. There is a china crystal program(Optima models and up) that uses 115F water. There are other options but you will pay slightly more for them. Starting with the OPTIMA the machines use sensors to vary the water temp according to the soil level. The programs will then operate in temperature ranges. For example if you use the Normal cycle it's max range will be 130F but if the soil level is light the temperature will be less than that. This helps reduce the chance of etching and improves energy usage. When you get to the Excella and LaPerla these have additional cycles that use lower ranges (104F through 120F) and take less time, but which will still clean a load. Miele describes these cycles as using their "glass care system" - (whatever) - designed to clean but be easier on glass. I used one today on a dirty mixed load and everything came out spotless. These models also have additional sensors which will adjust the number of water changes and match the water taken for each fill to the load size, and will also reduce or increase the cycle time based on soil level. The built in water softener is offered on the models starting with the Optima. This softener is not like those of the past or the one that was on my prior model. This one measures your water hardness as it is running in and will adjust it only as much as it needs to be, so that you don't get very very soft water being mixed with detergent and hot water. I wonder if the prevalence of etching has been caused by the way glasses are being made today? Or maybe it's enzyme detergents? Etching seems like a big issue now but I don't remember hearing that much about it in past years. Pre rinsing. I have never done it. Not with the model in 1996 a G885 and not with this one. I just scrape the food off the plate and load it in. I don't even do a rinse hold and sometime let everything sit inside for a day or two and everything comes out fine. And like aflowerfreak said most new DW don't require you to rinse before you load. There are others on the forum with this brand and the models you are considering so I am sure you'll get more input.

I'd agree that it probably is related to the internet connection, but I won't rush to blame the ISP just yet. It could be what I call a "dirty" connection. Essentially static on the phone line. Has this just started since moving to the new apartment? If so, I'd try a couple things. First, try a different phone jack. Then try a different phone cord. Do you have any noticeable static on your telephone? If so, that's probably it. If not, it could still be an issue, just not enough that you could hear. Another thing to try is to go to another phone jack. Do you have a community room with a phone jack available to try? Phone cords and phone jacks can get corroded, or the tiny wires in there get bent or otherwise damaged. If you don't have another phone cord handy, you could even try switching it around, that is the end that's plugged into the wall - plug that into the computer and vice versa. Another thing to try is unplug all other phones, answering machine, etc and try it. There could be an issue caused by one of them, although I' more apt to think it's related to the phone jack and line in the apartment. Another possibility, is there an alternate dial up number to try? Sometimes that makes a big difference.

From the sounds of it, I think you have the wrong plant...! If it's only recently planted, getting rid of it is likely the smart thing to do. I gather that, for whatever reason, wisterias are not as rampant spreaders in the UK as they are in some parts of North America, but they are vigorous growers everywhere- as you've found out ;-). Is it a Chinese or a Japanese wisteria? I have one of both, and both are grown as 'trees'. We planted the Chinese one 15 years ago and keep it to ~8-9'. We planted the Japanese one in 2007 and are keeping it shorter - ~6'. I ignore the complicated pruning instruction you see everywhere and just whack back into the desired framework all whippy new growth as it arises - can be an almost daily task when it is in active growth! All root suckers and growth from below the graft union (assuming there is one) get ripped off (not cut off - I'm trying to remove bud wood...). The Chinese wisteria virtually stopped producing root suckers after 5-6 years of age, but the Japanese one is still producing lots, so it is the more rampant grower in my experience.

No safety issue that I know of but it will be a different taste and different texture result. Dave
