At least in the EU it has come to the point where you have to figure out how to 'boost' the appliances into a 'normal' cycle, as the default is just the 'eco' setting designed to pass the test's 'A+++' rating criterium under ideal circumstances. I am 100% in favour of not wasting energy and water, just not by deception and false savings where people use more water 'pre-rincing' their dishes in the sink than a regular dishwasher used to clean them, or having to manually add 2 extra soak and spin cycles to get rid of detergent residue in a washing machine because the default cycle was 'optimized' for specific artificial test loads not resembling any real world family clothes mix. Many machines still have a button or hidden option to set them to 'normal' operation. For others you will have to resort to trickery or plain reinterpreting of what the different programs and settings actually mean to get the right result.

I just use a fraction of the recommended laundry detergent. Helps prolong clothing and colours too. Spot spray any actual stains. But I also fear automotive durability is being lost in the name of fuel economy by using excessively thin oils. Not just in the motor (easy to change yourself, just ignore the label where they can’t recommend thicker oils), but also CV joints, bearings, transmissions and differentials. I put 87 (US octane system) instead of the “required” 91 because the fuel mileage loss doesn’t make up for the added premium. But of course the manufacturer will never say you can do that because they’ll lose their fuel economy record. It might actually matter with a turbo, but I don’t have one.

  > I put 87 (US octane system) instead of the “required” 91 because the fuel mileage loss doesn’t make up for the added premium. Octane isn’t about gas mileage. It’s about compression. Lower octane gas is prone to auto-ignition at lower compression ratios. Running lower octane gas in an engine designed for higher risks catastrophic engine damage, as ignition can happen before the piston has reached peak compression.

    Meanwhile there are (a decreasing number, probably to claim better fuel economy) that state “91 recommended” but don’t require it. Reality is modern engines adjust timings to make up for lower than expected octane, because they have to deal with other situations that trigger it (e.g. elevation). But running an engine designed to take advantage of a higher octane at lower octane will have a fuel economy hit. But appears to be a single digit percents difference while reducing unit fuel cost by over 15% where I am.

      There are limits though, if you blow up your engine and they find 87 in the tank don't be surprised if the warranty is void.

        Is there seriously an ability and reasonable chance that they could and would test the octane in your tank? That is surprising to me.
        Scoundreller 3y ago
        I believe some newer cars do store data that could indicate lower octane gas was put in. But if you’re still under warranty and your engine blows up, it suggests a problem with the manufacturing itself. Exceptions could be if you put in E85 that’s not recommended as it has much lower energy and the engine needs to make a ton of adjustments for that which might be out of range.
      - Scoundreller 3y ago
        I’m loooooooong past warranty here. Lots of suggestions of engine thermonuclear destructions of the country (on internet for putting lower octane than “required”), but so far so good.

      > Reality is modern engines adjust timings to make up for lower than expected octane Correct, but the manner in which many do this is reactive (i.e. piezoelectric knock-detectors), not proactive. I put max octane in all the cars I own. I don't see a reason to play games with something like this.

I've been running "quad" rinse in my Maytag washing machine for the last 2 years because the "deep fill" selector isn't actually hooked up to anything. The machine is designed by a psychopath. It will cycle the water solenoid valves at least 100 times per wash session. It is like these things are designed to not only function poorly but also destroy your plumbing over time. It feels intentional. No sane engineer would watch this thing operate in a lab and think "yes. I've done a good job today". I've got a new machine on the way. No lid lock, EPA defeat switch, et. al. You cannot buy these at the normal box stores anymore. I had to argue with a boutique appliance salesman about my laundry preferences for an hour to get this sorted, despite the fact that I already knew precisely the machine I wanted.

  how would a solenoid valve destroy your plumbing?
  - bob1029 3y ago
    Quickly stopping the flow of water in a pipe can cause wear (damage) to joints in the system. Ideally, the solenoid opens and closes just one time for a fill cycle.

Can't read TFA and archive is sending me into captcha hell. BUT if this is about modern dishwasher taking 5h: yes, the last 2-3 hours are just drying the dishes in an energy efficient way. And it works perfectly fine for me and one cycle takes about half the electricity of my previous washer. Who cares how long a cycle takes, it usually runs over night anyway. This is the Eco program, and you can switch to an express program if you want a 2h cycle. If you have really dirty dishes (burnt stuff in a pot or whatever), you can enable extra hot water and even a high pressure zone where you can put the pot. It's a Siemens iQ300, BTW, but almost all dish washers I've seen now work this way. Is it really too much to ask people to skim the manual and figure out what these buttons do? Apparently so...

  I actually prefer to just let the dishes air dry anyway because I've found they last longer. I've wrestled a lot with the issue the article is mentioning the last few years. It's Goodhart's law applied to efficiency tests, where unrealistic standardized product tests get gamed in increasingly complex ways, and no one calls the tests on the unrecognized real-world problems being overlooked. Prerinseing, repeating cycles, mold problems, etc. One of the most frustrating things for me is how everything has become more automatized. Laundry machines are often organized around preset clothing types, for example, rather than cycle settings, which makes it difficult to control your wash correctly.

    > preset clothing types, for example, rather than cycle settings My LG washing machine has a wifi connection and one of the advertised feature was the possibility to download a custom washing program set from the app. I thought it kinda makes sense, because building a custom program involves many steps, timers and settings. A mobile UI would be better than the appliance's buttons. Well, imagine my deception when I got to try the app and the custom programs is just a list of a dozen more niche presets. No customization whatsoever. It's really like the machines we buy are no longer ours to control.

If your dishwasher isn't performing well on eco mode for typical loads, then you have a bad dishwasher. Good dishwashers exist. I'd recommend looking at impartial reviews, like Which?. Spending an extra £100 on a better dishwasher, to wash at 50 °C, will pay itself back several times, over the lifetime of the dishwasher. It adds up. You're wasting a fortune by washing dishes at say 70 °C. Also, pre rising dishes is an anti pattern, a bad habit which people have gotten into. These days the advice is specifically to not do it. Otherwise you're fooling the sensors, etc. Plus, energy efficient cycles are long, giving plenty of time for the dishes to soak and clean. If dishes aren't coming out clean, and your dishwasher doesn't have terrible reviews, then buy a bottle of dishwasher cleaner for £3, and put that in an empty hot cycle. That'll refresh the dishwasher to as-new performance. Clean the filter too, obviously.

  > pre-rinsing dishes is an anti-pattern The previous owners of my house had a very expensive KitchenAid, which we had to replace shortly after moving in due to the stench. There was pink sludge EVERYWHERE, and no amount of disassembly and cleaning fully removed it. Replaced with a Bosch (forget the model number, but one with the CrystalDry feature, which is awesome), which I like better anyway. I pre-rinse, because enzymes in detergent aren’t magic, and food eventually becomes a pink sludge.
  - smileysteve 3y ago
    Even if you do pre rinse, the soap grime will become pink sludge; the minimal required maintenance is rinsing the removable filter every month / 50 runs - a good wipe down (and lubrication of the hinges) and drain mechanism cleaning can help too. The magic part for the food particles is that they serve as abrasives during the wash process after being ground by the dishwasher grinder.
    - sgarland 3y ago
      Tbf I do religiously perform maintenance, and the previous owners did not, as evidenced by the HVAC filters being caked with dirt (and the aforementioned pink sludge). Re: dishwasher grinder, not all makes have those. My Bosch doesn’t.
