Fixing a SodaStream Jet

My SodaStream Jet soda maker started to act all weird, spraying a mix of water and CO2 all about.  Bah, I really like my Soda, and I'd hate to waste the expensive CO2 and otherwise make a mess.

So here is how to disassemble a Soda Stream Jet to try to figure out what's wrong with it.

My goal:  fix it!  If it isn't fixable, a new SodaStream Jet is available from Amazon.

It's notable that the SodaStream jet is mostly a snapped-together device, with the main body acting as a frame to hold all the components in place.

Let's cut to the chase: Here is how I disassembled the SodaStream Jet.

SodaStream Jet Disassembly Guide

1. Remove the Carbonator

This should be obvious. The carbonator is a pressure vessel that is relatively heavy and could even be dangerous.  Therefore, I removed it first.

2. Remove the black panel button

The starting point for disassembly is removing the big black panel lever.  This is the panel that everything hides behind.  Removing this panel is tricky, but it isn't impossible.  It took me about 10 seconds to fully remove it once I figured out how.

I use a flat head screwdriver to unsnap the tabs on the bottom left and bottom right of the panel lever.

Looking at the bottom of the black panel, there are two tabs, one on the left and one on the right.  These tabs fully secure the panel in place.  The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way.  Note in the pictures how I approach these tabs with my screwdriver.  I usually release the left side first, and then I release the right side.  Once both bottom tabs are released the entire black panel can be easily wiggled out off the machine.


3. Unsnap the filler assembly

The filler assembly is the first component under the black panel.  This assembly is the true heart of the Jet.  It includes the filler pipe, threads to hold the water bottle, a high pressure hose, and a couple of valves. 

To remove the filler assembly, there are two pivot posts that need to be released from the backside of the machine.  Again, using my trusty flat-head screwdriver, I release the right side and give a little tug on the assembly.  Once it's released on the right, I do the same on the left side.  The filler assembly is then released.

 4. Slide out the filler button assembly

There are two screws in the upper end of the machine that hold the fill button assembly in place.  This assembly moves pressurized CO2 from the carbonator and sends it into the filler assembly.

Here, I use a Phillips head driver to remove the two screws, allowing the filler button assembly to be withdrawn.

And now the major components are available for inspection, repair, or replacement.


The Problem with My SodaStream Jet

So on my SodaStream, it looks like a screw fell out of the filler assembly.

The filler assembly has to withstand full pressure of a new carbonator (maybe 2500+ PSI?), and so it needs all the screws in place to contain the pressure.  Without the screws, high pressure CO2 forces water out of the fill bottle and through the gap in the filler assembly, making a mess.

The screws seem to be stainless steel, but they developed some rust.  After a little rust set in, it looks like this screw weakened enough to break under high pressure.

That means that there is another half-screw inside the hole, and no way to get a good bite.

After a little more inspection, its clear that two screws have rusted and broken.

Next Steps

Normal screw and the rusted half-screw.
It may be possible for me to drill out the old screws and use slightly bigger screws, but my bet is that such a modification will significantly weaken the overall strength of the high pressure filler assembly.  Therefore, I am keeping this SodaStream Jet for "spare parts", and buying a replacement on Amazon.

Greenest Electricity Use

Most all of us use electricity.  When is the best time to use it?

Many people get this wrong.  They mistakenly conclude that using electricity during daylight hours is the best time to use electricity because that is when solar panels are delivering the most pure, clean solar energy.  

That's a bad conclusion.

During the day is when high electrical loads result in the dirtiest and least efficient electricity plants coming on-line.

Why do power companies run these dirty and inefficient power plants?  Because of YOUR customer demand!  You can reduce this demand by minimizing your power use during the peak hours of 3 PM - 9 PM.

The greenest time to use electricity is when the fewest inefficient, dirty electrical generation plants are in operation.  By minimizing your electricity use during the day, the dirtier power plants will produce less power, reducing their negative impact. 

During low demand times (late night and weekends), only the most efficient plants operate.  And so that's the time to use electricity, such as running your dishwasher, using your self-cleaning oven (yuk), running your kiln, or charging your car.  During the late night hours, only the most efficient plants are operating, to the point where the power companies have to resort to storing excess power.

To be super green: perhaps a Sunday morning at 2-5 AM in June or September, during moderate weather, is likely the champion. 

Best Times and Worst Times for Electricity Use

The following table is a generalization, but it is likely correct for more than 99% of the year.

"Greenest" Times for Electricity Use
2 AM to 4AM

Better Times for Electricity Use
11 PM to 7 AM

Worse Times for Electricity Use
7 AM to 11 PM

"Least Green" Times for Electricity Use
3 PM to 9 PM

Some of my Strategies

  • When: Schedule to run at roughly 4 AM - 5 AM.  Empty when I awake.
  • Do not use "dry" feature. 
  • Use quality detergent to make "heavy" cycle unnecessary.
  • Wash full loads only, but not overloaded.
  • Scrape dishes into compost bin, reducing debris going through washer.
  • Minimize washing by hand, a huge waste of water.
  • Avoid very hot days, due to heat exhaust that puts more load on air conditioning.
  • When: Sundays, in the morning as soon as I wake up.
  • Use a quality detergent and cold water mode
  • Large loads only.  Any less-than-full-load amount of laundry has to wait a week. 
  • Avoid wet, humid days to greatly reduce dryer times.
  • Avoid extremely hot/cold days to reduce air exchange with outdoors.
Vehicle and Equipment Battery Charging
  • Charge equipment overnight.
  • Avoid late afternoons and evenings - the very worst time to gobble up electricity.

Getting your dishwasher to last longer
