Cold Logic

Your humble blogger always hand-washes dishes with hot water. There's no question that hot, soapy water cuts oils much better than cold. Also, more bacteria are killed, and running the hot water while rinsing reduces grease build-up in the drain.

But heated water is not better than cold when it comes to washing clothes, according to Tide experts:

P&G has sold a line of Tide designed for washing in cold water for almost two decades and still sells that product, called Tide Plus Coldwater Clean. The latest campaign pitches the overall brand as being effective in cold water. The company says it has reformulated Tide over the years to be more effective...

P&G says that cleaning clothes in cold water could save $150 a year on a household’s energy bill, or somewhat less with the high-efficiency washing machines used in about 70% of U.S. households.

A Clorox scientist says warm is more effective than cold:

[Mary Gagliardi] says warmer water is generally the best way to ensure clean clothes, especially in colder climates. Ms. Gagliardi says manufacturers are able to test garment-washing in water as warm as 85 degrees Fahrenheit and define it as a cold-water wash according to levels set by standards organization ASTM International. A warm cycle is around 100 degrees, while hot is 122 degrees, she says.

“If you are in Minnesota right now and your cold-water temperature is 45 degrees, some people are washing in temperatures barely above freezing,” she says. “You are not going to get any cleaning done in 49 degrees.”

I'll stick with what I learned at the kitchen sink when it comes to washing clothes.

Call me clothes-minded, but warm is better.

Education is Everywhere, If You Just Look For It

Many of the conveniences of middle-class life are taken for granted, like in-house washers and dryers.

After the old Kenmore dryer failed 10 days ago, I expected to pay $500 for a basic model at Home Depot, Costco, or Best Buy; $700+ would be the all-in replacement cost after delivery, installation, sales tax, and removal of the old dryer.

YouTube showed that repairs were easy--even allowing that it would take me ten times as long as the professionals in the videos--so it couldn't hurt to try to diagnose the problem and attempt a fix (the parts would probably cost less than $50).

I had to promise the household CEO that I wouldn't dither; going to the laundromat was not only inconvenient but in the coronavirus era could be hazardous to one's health because of proximity to others in a warm, humid environment. If the task could not be done in a week, we would buy a new dryer.

Lint obstructed air flow from the clothes drum

After opening the bottom panel and unscrewing the lint cover for the first and only time in 13 years, the likely source of the problem became apparent: lint was jamming the air flow throughout.

Wearing a dustmask, I scooped out handfuls of lint, then used a brush and vacuum cleaner. The dryer had been working harder for at least a year, and the longer drying time finally burnt out one of the circuits.

Pulling out the metal housing for the heating element, I checked for a break on the three devices ("test for continuity" is the technical term) that were most likely to fail: the fuse, thermostat, and heating element.

Testing for continuity

It was the heating element. Ordering a kit for all three parts for $34 from Amazon, I replaced the heating element and kept the thermostat and fuse if either of them blows.

I'll spare you the details of putting everything back together and cleaning out more lint, dear reader. Suffice it to say that the dryer is working again, more efficiently than it has in a long time, and should be good for 2-3 years.

Comments: I did derive satisfaction from:

1) not having to spend $500-$700 on a new dryer;
2) not having to send the old one to the landfill or recycling plant;
3) being able to fix it myself.

But the most satisfaction arose from learning how the dryer worked. It's both simple and ingenious. Discreet writers call it a negative pressure system, but your humble blogger prefers simpler language.

Heating element + small parts

The motor both tumbles the drum and sucks the hot moist air out of the drum and expels it through the exhaust. The drum in turn sucks in outside air that has passed over the heating element. The features (tumbling, drum, timer, moisture sensing, varying the heat, etc.) that we see in current dryers were all invented before 1960.

Frankly, I am in awe of the engineers and inventors that created wonders, both big and small, in 20th century America.

A Lot of Trouble to Replace

Bent out of shape: I did that without help.

The best $150 I ever spent was in 2008.

Our 20-year-old dryer was irredeemably broken, and the new dryers at the time were too wide and cost at least $500, not including tax, installation, and hauling the old one out. On Craigslist the ideal replacement miraculously appeared. It was narrow enough, and the door hinge was at the bottom which was a "try-for" specification from the household CEO.

The seller, a lady in Palo Alto, had bought a new laundry pair and thought she could find a use for her old dryer but had given up trying. Her Kenmore had been sitting on the back patio for a year, covered with a tarpaulin. Before taking it, I asked her to plug it in to prove that it worked. It did.

The dryer easily fit in the 11-year-old Dodge Grand Caravan. (I always use an old car--for different reasons, of course--when I have to negotiate a purchase, do charity work, or go to crime-ridden areas like San Francisco.) The used dryer worked like a champ, and the garbage haulers took the old dryer on one of the two annual bulk-disposal days.

[Note: I forgot that I had blogged about the purchase in 2009. Most of the details are still clear in my memory. I'm not that far gone....yet.]

This week the dryer that had served us for 13 years finally failed. The drum turns but doesn't heat; the problem was likely due to one of three parts, said the Internet, each of which costs less than $50. But first the bottom cover plate has to be opened. It had never been removed by myself, nor likely the original owner, too, so I'm using brute strength and WD-40 against the rusty metal. So I can't even get to step 2: testing the continuity on the three parts to see which of them is busted. So I'll be spending a bit more time, probably through New Year's weekend, working the problem before giving up.

Fortunately for me the household CEO did not act disappointed though I bent the bottom plate out of shape. She knows that the hired help doesn't respond well to criticism and will be a lot of trouble to replace.

Laundry Inequality

(WSJ photo)

When we stretched our finances to buy our first house--it had three bedrooms--over 40 years ago, we had to sit on bare floors in the living room and two of the bedrooms.

Despite the lack of furniture our first major purchase was a Kenmore washing machine and dryer from Sears. The time wasted driving a half-mile to the nearest laundromat and waiting in line for a machine on the weekends (each of us was working more than 40 hours a week and driving at least a half-hour each way) was at least half a day.

Compared to the nearby coin-operated machines in college or the apartment complex, the time-sink was intolerable.

Never had we derived such pleasure from new equipment--and we're talking about a time when we got our first color television and our first microwave oven (both gifts). It's not much of an exaggeration to say that having one's own washer and dryer is a big step to achieving the American dream.

We were reminded of that distant past when we read about a new problem, a coin shortage, that has afflicted the appliance-deprived: [bold added]

Now I need quarters only for San Francisco parking
meters,which currently charge $2.50/hr. minimum
(and I'd rather not give the new meters a credit card).

The scarcity of spare change—brought on as people leaned on digital transactions and fewer coins circulated—has pushed the quarter-dependent to extremes. Many have spent hours trekking across their cities in search of coins they used to easily procure from local bank branches. One couple hauled four loads of laundry across several states where they could use a relative’s machines. And in some buildings, the yearning for clean sweatpants has resulted in neighbors forging closer bonds.

The flow of change first slowed in the spring of 2020. Restaurants and retailers posted signs encouraging digital and credit card payments and even asked people to exchange spare coins. The problem eased toward the end of 2020 but made a comeback in March as businesses were preparing for an influx of cash transactions after vaccination rates ramped up. Around that time, coin requests from banks began to outpace deposits, according to the Federal Reserve, which provides cash to banks through its regional banks.

Now there isn’t enough coin to go around, and the central bank is limiting orders on pennies, nickels, dimes and quarters. Banks and other financial institutions deposited about 15% fewer coins at their local Fed banks through mid-July compared with the same stretch last year, the central bank said. Coin deposits were 45% below 2019 over the same period.

Some bank branches are saving coveted coin rolls for their customers, according to apartment dwellers who have asked for quarter rolls at banks where they don’t have accounts. Other banks are telling would-be washers that they have no change to spare....

Digital options, such as reloadable payment cards or smartphone apps are gaining ground, but quarters have long been the default payment option, said Matt Miller, president of Coin-O-Matic, which outfits laundry machines with a variety of payment systems.

Demand for machines equipped with digital payment capabilities has roughly doubled since the start of the pandemic, Mr. Miller said. The most popular digital payment method is an app that users load money for laundry and connects to laundry machines via Bluetooth. Washers and dryers that accept credit or debit cards are less common because they require real-time Internet connections, which can be difficult to guarantee in the basements where many laundry rooms are located.

Wealth inequality manifests itself in housing, transportation, health care, and diet, but take it from one who's been there, the washer-dryer gap is more important than everyone thinks.

You Gotta Have Balls

It's old technology that we've just adopted: Tennis balls reduce drying time.

They move around between the items in the dryer, allowing the warm air to circulate more freely and thus reach more surface area of the drying items. They also seem to reduce static electricity in the finished load.

There's an optimal number of tennis balls that will minimize drying time and maximize "fluffiness", however it's defined.

In my younger geekier days I would have worked the puzzle, but now that I'm older (and lazier) 2-3 balls seem good enough, so that's what we'll use.

In many, many areas of life having more balls is helpful.

Replacing the Pump on a Whirlpool Duet GHW9200LW

The pump is easy to access.

Over the weekend our ten-year-old washing machine stopped working. (Of course, the extended warranty had expired without a renewal offer two years ago.) Error message F02 flashed on the control panel, and various websites advised that the problem was either a clogged drain or the pump. It was a simple matter to open the drain---although I didn't appreciate how many quarts of water would spill on the floor--and take out the hair, paper clips, and pennies that had accumulated over the years.

Green plastic must have been on sale that day.

This solution only lasted a couple of wash cycles, after which the pump emitted a loud rattle and gave up the ghost.

Having bought "replacement" parts in error before, your humble amateur handyman looked up the exact part number for the pump and ordered it through Amazon for about $100, including tax and shipping. It arrived four days later.

Whirlpool didn't make it easy for the home handyman by using common Phillips or slot screws, but, fortunately, I had bought a Torq screwdriver for a computer project. The old pump took only a few seconds to remove.

The new pump was colored a light green; well, with the metal toe panel on no one has to look at it. The most time-consuming part of the task was ensuring that the hose clamps were secure. A couple of light test loads didn't reveal any drips. The cover will be left off for a few days to watch for leaks. [Update - August 3rd: no water appearing, the panel was put back on.]

Comments:

1) There was little risk that failure of this do-it-yourself repair would make the situation worse (unlike other projects). A professional could still be called and likely wouldn't have to spend any more time because of my failed attempt.

2) No special equipment or knowledge was required, which for example, would have been the case with the control panel or the motor.

3) The parts investment of $100 was modest; if it were $300 I would have called someone in.

4) The investment of personal time--2-3 hours over several days--was also modest, little more than the time required to supervise a professional repair. Also, no one had to be home for an appointment.

5) It took about as along to fix the pump as to write about it. Frankly, fixing it was more enjoyable.

Pleasant Surprise

I’ve had bad luck (of the self-inflicted variety) with my Bluetooth earpieces. I bought my first one a few months before the hands-free cellphone law went into effect in 2008. A few months later it went through the wash cycle and came out dismembered and totally non-functional. My second earpiece avoided laundry malfunctions because it resided in my briefcase when not in use. After years of jostling and pounding it too passed from this mortal coil.

Despite a resolve to keep a close eye on the third Bluetooth, I forgot that the tiny device was buried deep in the pocket of my workout sweater. It went through the washing machine yesterday. I felt a sharp pang of chagrin as I saw the red LED flash from the bottom of the drum. The good news, of course, was that the LED was flashing at all.

"Takes a washing and keeps on flashing"--not the same ring

Modern electronics equipment is both complex and fragile. Even brief exposure to water can ruin a cellphone or camera. Timex’ ad slogan from the ‘60’s, “it takes a licking and keeps on ticking” seems such a quaint anachronism that even Timex has abandoned it.

I dried the earpiece, recharged the battery, and tested both transmission and reception. Unlike its 2008 ancestor, this Jawbone 2 worked like a champ. Pleasant surprises, though they be trivial, brighten my day. © 2010 Stephen Yuen
