Hey guys, would a water injection pump survive being submerged in water?

Someone did a stupid prank and loosened the water filter body next to the pump. All the water from my tanks drained and filled the small cavity on the left side of the trunk where the pump resides.
I noticed what happened well over 24 hours after that prank. The car was sitting by my place.

What do you think?

 

damaged. I think someone owes you a new pump. Those pumps are only sealed at the impeller, and I believe 24 hours of soaking would destroy it.

 

Hairdryer and wait a day before applying power. It might still be good.

 

Throw the pump in a big jar of rice and let it sit for a week.

 

I think you needed the word rice in that sentense somewhere...

 

I dried the pump as best as I can.
I'll bench test it and let you guys know..

 

My son left his DS out in the rain for several days. It was completly full of water. I remove the game card, shook out what water I could, and stuck it in a tupperware with a full 1# bag of rice. One week later, I turned it on, and it was fine.

Let it sit in the rice for a week, the bench test it.

 

I totally understand the rice treatment, but the pump is essentially just a DC motor. Meaning, it has a couple of soldered connections, and no electronics inside.

I'll just do some basic resistance checks across random points inside the motor to rule out corrosion.

 

Just came from a meeting at the bank and now I'm officially a signer on the company account. So now not only will I be making and printing my own check, but now I can sign it too.

I'm really loving this promotion.

 

miata finished moew, yes?

 

3 hours of master's-level boolean algrebra on tues/thurs can blow me.

This is the most boring subject I've ever taken. By far. This is so incredibly freaking boring, ughhhhh.

 

When one is taking a masters-level course in a given subject, others might infer that one is preparing for a career in a field which might require mastery of said subject.

 

my wife was required to take some algebra class for her teaching degree... I am not lying when I say that she finished her hand written assignments in crayola crayon.


....she did get reprimanded for it for being a "smartass"...


my woman is awesome.

 

This would be the case, if I had not written extensively in assembly and low-level C for years (Read: I have mastery of this subject many times over, and in production software no less).

Boolean algebra are bitwise operations at the heart of it. All I have to do is mentally convert a 1 to a T and a 0 to a F or vice versa, and remember the difference in notation (* and ^ for example)

Said program requires electrical engineering/boolean algebra courses in order to graduate, and it makes sense in that it requires a deep understanding of how what we are doing work, but FFS. This is torture for people who actually know this ****.

Your wife is completely awesome ;b

 

I'm beginning to hate these side loading washers with a special sorta passion. Damn things barely get the laundry wet in the name of water savings..
I wish there was a way I could hack the Siemens/Bosch code to get them to take in more water.

 

side load is a joke.

 

I know exactly the ones you mean. They were pretty popular in Germany as well, if I recall.

Oddly enough, here in the US, so-called "high efficiency" washers are starting to become popular. They are typically top-loading as opposed to side-loading, but operate on a similar principle. The mechanical auger is removed, and a few teaspoons of water are allowed to circulate through the basin via a pump-jet.

In addition to being ridiculously expensive and not doing a very good job of washing laundry, they are annoyingly complex as well. Instead of a conventional AC motor, they use a three-phase brushless DC motor.

In the one which my mother owns (I can't recall the brand) I've had to dismantle the motor and clean / readjust the little daughterboard with the hall-effect sensors three times. It uses a crappy edge-connector that, when exposed to vibration and humidity for long enough, tends to oxidize and become intermittent. When it detects so much as a single fault in the sensors, it immediately shuts down.

For a while, it was a Christmas tradition in our household. I'd fly back to Florida to spend time with family, and among the list of electrical & mechanical things that had gone wrong over the past year and needed my attention, the washing machine was always among them. This past year I finally said "**** it" and soldered the connections.


But really, I see no reason why people in the states are willing to pay 50-75% more for a washing machine that saves them just a few dollars a year in water consumption and yet is vastly more complex and less reliable than the old agitator-style machine that it replaced, not to mention doing a much worse job at actually washing clothes. They still sell the old machines (even in California), and I simply cannot understand why anybody would purchase anything else.

Has it become a status symbol to be seen to own a "modern" washing machine?


For what it's worth, not all front-loaders are crap. When I was in college, we had front-loading machines in the dormitory's laundry room. But they were the old-school units that filled up halfway with water. As I recall, they did an excellent job and were quite fast.

 

The side-loaders also have another chronic problem -- mold growth around the door seal.

Because the door has to seal tightly, and because of the difficulty of draining off the water from this area, unless you leave the door open to allow airflow, mold grows on the door seals and can leave stains and smells on your laundry.

I've read that the newer generation of side-loaders does a better job of draining all of the water BUT I'm still seeing that manufacturers recommend leaving the door open to avoid mold growth. This is ridiculous.

All of the appliances in the house we bought 3 years ago were quite old and ready for replacement...except for the washer and dryer. They are very nice Maytag Neptune side loaders. Sadly, they are plagued by the mold problem.

 

Yeah, that "spend $1000 to save pennies in water" thing always bugged me. I have yet to find anyone who owns the fancy front loaders that actually like them.

My brother has to clean his washing machine about once every 3 months, or it smells. Really stinks, and makes the clothes smell, too. So, he has to scrub the thing. Uh, no thanks, I'll keep wasting water.

 

We tried a few things, running an empty load with white vinegar, wiping down the seal with a mild bleach solution, but ultimately the only thing that really works is to always, always, always leave the door wide open for maximum airflow.
