My 12 year old Whirlpool front loading washing machine died last week. It stopped working with error code E 28 (which means "communication failure"). According to online sources, this could be as simple as a loose connection, but was more likely to require one or two circuit boards, the central controller and the motor controller board.
This washing machine, which I may have even praised earlier in this blog, had never had any issues before.
Some friends bought a larger model Whirlpool front loader and had many problems, finally giving up after the first expensive repair didn't last very long. They used the machine for a total of less than 5 years if I remember correctly. They then bought the cheapest Amana top loader to replace it. I figured mine was better, possibly, because it was made in Germany (likely the former East Germany where Whirlpool bought a factory).
Well now it doesn't appear that any consumer Whirlpool washers are made in Germany any more. And Consumer Reports rates Whirlpool 3/5 in reliability, while rating Samsung 4/5 and LG 5/5. So it appears that LG are now the machines to get, so that's what I'm buying to replace my Whirlpool.
I was also more than a bit miffed that after waiting one week for service from the Whirlpool authorized service in San Antonio, they cancelled my appointment with one day's notice because they hadn't received the "likely" replacement part(s) from Whirlpool. They suggested I make another appointment another week out, but I suspect there was no guarantee they'd even have the part then.
Finally it bugs me that a washing machine should die from a circuit board problem. My nearly top-of-the-line washer had many special features including fan, sensing, steam, and sterilize. It must be chock full of electromechanical parts whose long term performance probably cannot be assured. But the factors involved in circuit board design are fairly straight forward. Most electronic components have predictable lifespan of 20-100 years, which is also probably thermally derated. Just about any circuit can be made to last about 20 years before the most failure prone parts--electrolytic capacitors--would be likely to fail. UNLESS the thermal properties are not fully accounted for.
So any decent electronic engineer could design a circuit board that would last 20 years, whereas electromechanical parts are not as predictable. In my mind there's just no excuse for a circuit board failing a complex and expensive system in just 12 years. (And even less excuse for failing in 5 years.)
Furthermore of course a circuit board will be entirely proprietary (which computer chips and programming nowadays too) and so it will only be obtainable from the factory and as long as the factory chooses to support it.
Now it also seems that the more complex a machine, the more likely it is to fail earlier. But it often seems that the failures found on the complicated top-of-the-line models are the same as the failures which found on the cheap models. For example, say you have a fancy car with power door locks, power windows and automatic climate control. You might think that would lead to reliability problems. But the power windows and the automation part of the climate control rarely fail on fancy cars. Instead, it's the usual stuff that fails on all models regardless of how fancy.
When and if we ever create a Sustainable Society, planned obsolescence will not be acceptable. Stuff should be designed to be easily repairable with generic parts.
Here's an interesting article about washing machine reliability. Their top recommendation for longevity is the Speed Queen toploader, and they talk a lot about Speed Queen and how top loaders will last longer. But they also recommend the exact same LG model I have decided to buy as their top front loader recommendation, the WM4000HWA. The Speed Queen frontloader costs over twice as much and actually seems to have slightly higher service calls, though it might be repairable for longer. Like me they are infuriated that washing machines should have so many computer module failures when well designed computer modules should last decades.
