One basic point that the video does not cover are the lights on the front of the machine. When the green light is lit the machine is receiving power, and when the orange light it lit the water tank sensor is sensing water is present.
+
 
+
===Adjusting Brew Pressure===
+
====Reservoir Version====
+
Adjusting brew pressure on the reservoir version of this machine is simple. The adjustment screw can be found at the top of the machine underneath the drip tray cover. {{#ev:youtube|https://www.youtube.com/watch?v=l9Xv1ImphAU|480|center|||start=55}}
+
The brew pressure should only be adjusted one quarter turn at a time. A small adjustment will make a large difference in brew pressure. Turning the screw clockwise will raise pressure, and counterclockwise will lower it.
+
 
+
====Profi Version====
+
 
+
The brew pressure adjustment on the Profi version of the machine will be accessed from the bottom of the machine. Again, only quarter turn adjustments should be made.
+
[[File:ECM Brew Pressure Adjustment Screw.png|400px|thumbnail|center|The adjustment screw is circled in red.]]
+
 
+
One trick for easily accessing this screw can be found in the video below, where they show how to use the portafilter to stand a prosumer style machine up so that the bottom can be accessed. The machine in the video is slightly different, but the same method can be used to access the bottom of this machine.

====No Flow At All====
 
 
Since there are two versions of the ECM Technika IV you will need to follow the appropriate instruction set to resolve a no flow issue for your unit.
 
 
=====Reservoir Version=====
 
{{Troubleshooting-Prosumer-No-Flow-At-All
 
|water_supply = Reservoir
 
|sensor_instr = The water tank magnet may be sitting in the machine incorrectly, or the water tank sensor wiring may be loose or disconnected.
 
###The water tank magnet is embedded in a white plastic float, which can be found in the front left corner of the water tank. The float should be positioned so that the magnet is on the top and is facing the corner of the tank. [[File:ECM Magnet Alignment.png|200px|thumbnail|center|Properly Aligned Magnet]]
 
###The magnet needs to be aligned with this sensor. If the magnet is positioned properly but the machine still thinks there is no water, then there may be a wire loose/disconnected on the sensor. [[File:ECM Magnet Sensor.png|200px|thumbnail|center|Water Tank Sensor]]
 
|pump_instr  = Check to make sure there are no loose or disconnected wires on the pump.
 
|valve_instr  = The machine may need to be professionally repaired.
 
}}
 
 
=====Profi Version=====
 
{{Troubleshooting-Prosumer-No-Flow-At-All
 
|pump_instr  = Check to make sure there are no loose or disconnected wires on the pump.
 
|valve_instr  = The machine may need to be professionally repaired.
 
|socket_style = Yes
 
}}
 
 
 
===Machine Is Leaking===
 
 
{{Troubleshooting-Prosumer-Bad-Gasket
 
|gasket_instr = Instructions for replacing the group gasket can be found on pp.30-31 of the machine's manual.
 
}}
 
 
{{Troubleshooting-Prosumer-E61-Leak
 
|lever_style              = Lever
 
|lever_leak_instr        = A blowout of the lever assembly can be seen on p.10 of the machine's parts diagram. The o-rings that will need to be checked are listed as part 20 and part 22 on this page.
 
###To access these o-rings remove the end cap of the lever assembly using a flathead screwdriver.
 
###Once this is removed the other components of the grouphead assembly can begin to be slipped off. The bolts that the lever slides into can be removed with open ended wrenches or an adjustable wrench.
 
###Inspect the o-rings and make sure they are not damaged. It's possible that they are just dirty and need to be cleaned off and reseated. If they are damaged, broken, or shows signs of chaffing then they will need to be replaced.
 
###Inspect the valve components well to make sure they are intact.
 
###Reassemble the components and see if leaking is resolved.
 
|top_valve_leak_instr    = A blowout of the top valve assembly, known as the mushroom or trumpet valve, can be found on p.10 of the machine's parts diagram. There are a few components which can be contributing to the leaking. There are two o-rings, listed as parts 2 and 6 on this page of the diagram. There is also a valve assembly shown as assembly 10 on the same page.
 
###To access these parts use an open ended wrench or adjustable wrench to remove the smaller top bolt of the E-61. This will give you access to the first o-ring and spring assembly.
 
###To access further down into this part of the grouphead use a wrench to remove the large bolt. This will let you access the other o-ring, another spring assembly, and the other valve assembly.
 
###Inspect all of these components for integrity. Clean any dirty parts and replace any broken parts.
 
###Reassemble the grouphead and see if the leaking is resolved.
 
|bottom_valve_leak_instr  = A blowout of the bottom valve assembly, known as the release valve, can be found on p.10 of the machine's parts diagram. There are two o-rings in this assembly, listed as parts 33 and 38 on the diagram, and two valve assemblies, listed as assembliess 30 and 35 on the diagram, that can be causing the leak.
 
###To access these parts use an open ended wrench or adjustable wrench to remove the smaller bottom bolt. You will be able to access part 38, the o-ring, and assembly 35, one of the valve assemblies. Inspect the parts. If they are dirty clean them off, if they are broken replace them.
 
###To access the next o-ring and valve assembly use a wrench to remove the larger of the bolts. Again, inspect the parts for cleanliness and damage. Clean or replace as needed.
 
###Reassemble the release valve and test to see if the leaking is resolved.
 
|E61_group_cleaning_instr = Instructions for cleaning the entire E-61 can be found by clicking [http://coffeetimex.wikidot.com/e61-group-servicing here].
 
|E61_attach_instr        = There are two possible reasons for the machine to be leaking from here.
 
##The first is that one of the plumb lines connected to the back of the E-61 is not secure resulting in a leak. This will need to be tightened from the inside of the machine. You may see leaking from the bottom of the machine as well if this is the case. Remove the top of the machine and look towards the front of the machine. These lines will be located on the back of the faceplate, opposite to where the grouphead is seated. They are listed as parts 7 and 10 on p.8 of the machine's parts diagram. Use an open ended wrench or adjustable wrench to tighten these down. If the leaking persists you may need to apply white teflon plumbers tape or a sealing compound such as food safe permabond.
 
##The other possibility is that the E-61 group chassis gasket is not sealing tightly, or is worn out or damaged and will need to be replaced. The chassis gasket is listed as part 15 on p.10 of the parts diagram. There are two bolts which secure the E-61 to the machine chassis, causing it to press on the gasket and create a seal. First try tightening these two bolts down. The bolts assembly is listed as parts 11-14 on p.10 of the parts diagram. If tightening these bolts does not resolve the leak, then the chassis gasket will need to be replaced.

{{Troubleshooting-Prosumer-Wand-Leak
 
|knob_instr        = The steam knob assembly of this machine is not considered user serviceable, and the machine should be sent in for repair.
 
|tip_instr          = <br />
 
##The steam tip o-ring is easy to access. Simply unscrew the steam tip and there will be a small o-ring between the tip the wand arm. Inspect this o-ring for damage and clean it.
 
##The hot water tip is a little more complicated, but still easily accessed and cleaned.
 
###First unscrew the tip assembly from the wand arm.
 
###There will be an o-ring between the tip assembly and the wand arm. If the leaking was coming from here, then this o-ring needs to be cleaned and repositioned, or if it is damaged it will need to be replaced. [[File:PRO_700_Hot_Water_Tip_Removed.jpg|200px|thumbnail|center|The red arrow points to the o-ring for the hot water tip.]]
 
###If the leaking was coming from farther down on the tip, then the tip will need to be disassembled further to troubleshoot. To disassemble the tip further simply twist the two halves of the tip assembly in opposite directions. Alternatively you can screw the tip back onto the machine and then just unscrew the bottom half of the tip; this will give you a better grip on the tip to unscrew the two halves. [[File:PRO_700_Hot_Water_Tip_End_Removed.jpg|400px|thumbnail|center]]
 
###Once the tip is apart it will separate into three separate pieces. There will be three metal pieces and another o-ring. Inspect the o-ring for cleanliness and damage. The metal pieces can be soaked in a solution of hot water and backflushing powder to remove any scale buildup on them. [[File:PRO_700_Hot_Water_Tip_Parts.jpg|400px|thumbnail|center|The disassembled hot water tip.]]
 
|ball_joint_instr  = <br />
 
##These instructions apply to both the steam and hot water wands. First remove the wand arm. This can be done by unscrewing the hex shaped nut at the top of the arm, part 28 on p.12 of the parts diagram.
 
##Once the wand is removed you may have parts stick to the valve assembly. Do not lose these parts.
 
##If the leaking was coming from the top of the securing nut, check the o-ring (part 8) to make sure it is clean and not damaged.
 
##Inspect the tension spring to make sure it is in good condition. The spring should be really firm. If it is easily compressed then it may need to be replaced. At the bottom of the spring are parts 11 and 29. These mate with the ball joint on the wand to let it pivot. Make sure these parts are clean and reinstall them.

Install It

  1. Find a swanky spot in your home for your new machine to live, preferably where the morning sun can strike the mirror-finished housing so you can fully appreciate the bright idea that is your purchase.
  2. Get the power cord and the accessories out of the box.
  3. Plug the machine directly into an outlet. Don't plug it into surge protectors, extension cords, or timers.
  4. Fill the water tank.

Get it Good & Hot

It's time to get heated.

  1. Turn on the machine.
  2. Lock the portafilter into the group head.
  3. Wait 30 minutes.
  4. Take this time to start reading up on how to brew and froth below, if this is your first machine or you're new to pulling shots.
Heating Prosumer Image.jpg



Get a Handle on your Tamp

  1. Level off the grounds in your portafilter
  2. Keep your tamper level with the basket
  3. Apply consistent force downward, evenly, and level with the portafilter
    • 30 lbs. of pressure is a good rule-of-thumb to follow for beginners
Wiki-YT-HowToTampEspresso.jpg

How To: How Do You Tamp for Espresso?



Brew Better

  1. Lock the portafilter into the brew group.
  2. Lift the brew lever all the way up.
    • Aim for 2 to 2.5 oz. in about 25 seconds.
  3. Drink your shot to test.
  4. Repeat until properly motivated to get work done.


The big secret to finding that exact flavor you're after, that big punch-in-the-mouth feel, is dialing in your grind. For a basic rule-of-thumb, a coarser grind makes for a lighter, fluffier coffee, and a finer grind makes for a more intense, flavorful espresso. Check out the video on the right for more info.

Brew the Best You Can Brew

For more control, you'll want to know about how brew ratios and weighing your shots can help you keep a recipe so you can repeat your favorite results. Brew rations and weighing take all the guesswork out of the process so you always know what you're going to get.

How To: Basic Espresso Technique - Brew Ratios & Weight



Preinfusion and You

You can think of preinfusion is sort of a special trick to help bring out the best flavor in your coffee just before extraction. The idea is to softly wet the grounds before pressure is exerted by the pump.

  1. Bring the brew lever to a 45 degree angle. You will feel it stop there.
  2. Lift the lever slightly higher. This will allow for water to flow, but with no pressure from the pump.
  3. Lift the lever fully when satisfied and you're ready to brew.

Quick Tip: Six Common Milk Frothing Mistakes



Steam & the Heating Sweet Spot

The literal sweet spot for steaming milk falls between 140°F and 155°F, with smaller drinks on the lower end and larger drinks on the higher end. A quick rule-of-thumb we follow is to steam just until the frothing pitcher becomes a little too hot to hold comfortably.
