Good Thing When Home Appliances Are Ancient Antiques
Last week we published 2 articles about repair of washing machines and other "modern" home appliances. A week prior to those articles I had written about this same problem, based on a more preliminary investigation and online "research" (or just search). There was no way to fix it on my own. No way, Jose! The conclusion was, those appliances are made to die within years, based on people who work with these everyday (morning 'til evening, sometimes more).
What about home alarms? I basically didn't have one at home until I was 5 or 6. I never got to check the internals of any until yesterday. First time in my life (thankfully) because a careless tenant forgot the code and didn't even attempt to enter a code. This sent the alarm into a severe panic that could not be easily stopped by a standard reset (that did happen before; the mitigations weren't so complicated). Once the fuse was removed not even the internal backup battery could keep the thing's sirens and physical bells (and bright flashes) going, but then it required a lot of work recovering settings (it reverted back to factory defaults).
With the alarm fixed today (it cost time, but not money), let's examine what it takes... to take them out of a 'fuzzy state' or out of panic/tamper mode. It's not surprising that it's hard and that many online videos/pages are made for many different alarm models; alarms are meant to be self-protecting for high survival/durability... in case of break-ins, whereupon intruders can shut down the power, unscrew panels, cut wires and so on. The alarm, under particular conditions, is meant to not trust the person touching it; if it cooperates easily, then it ceases to alarm. Then it's considered not effective.
After lots of work that could be avoided (but nevertheless ended up as an educational exercise - the first in my life!) I'd describe these appliances as fairly modular chipsets with easy-to-use (or pull) components and manuals that are not too difficult to follow. They ought not necessitate a certified professional coming in. Those aren't "blackboxes". Unlike some home appliances I've come across, swapping components isn't hard, the screws are fairly standard, and the lighting mechanisms are relatively straightforward in the sense that they indicate what is wrong or what went wrong.
Having said this, based on an alarm about 20 years old, it seems safe to guess some of the more "modern" ones don't or won't last several decades, only years, They probably try to connect to Wi-Fi and leverage 'apps' etc (like the more modern smoke/heat alarms). Thankfully I've never experienced those and hopefully never will. What happens when old protocols cease to be supported? Or servers you don't control are shut down? Or the "apps" are no longer compatible with whatever version the skinnerboxes have?
Fixing the washing machine cost just over 150 pounds (several very large components needed to be replaced with new ones), dealing with the alarm has cost only time. The washing machine was purchased in 2020 (I installed it myself during lock-downs) and I'm told all washing machines made in the past decades are ridiculously flaky; they'd barely last 5 years. Few very expensive brands (like Miele) still have a long life, but not many people wish to spend that much money (they're like 3-4 times more expensive than the rest). █
