Subject: Programming an Oscar?
 

I found this information online regarding programming an Oscar.  Has anybody tried doing this?  Just curious if it works or not.  I'm not home right now so I can't test it out.

Timed Dose Adjustment

To enter the programming mode, switch
on the machine using the I/O button
holding down the 1 coffee button
until the light on the coffee button
begins to flash.

Press the coffee button to begin
pouring and press it again when the
poured dose is as required.

To exit the programming mode, switch
off the machine using the I/O button
and then switch it on again.



Preinfusion on/off

To enter the programming mode, switch
on the machine using the I/O button
holding down the coffee button until
the water presence light begins to
flash.

Switch the preinfusion on/off by pressing
the coffee button. When the light is on/off,
the preinfusion mode is also on/off.

To exit the programming mode, switch
off the machine using the I/O button
and then switch it on again.

WOW!  I never knew there was a way to program the Oscar..maybe it's a new feature?  I found the online manual and it does show how to program the Oscar for both Timed Dosing and Pre-Infusion: http://imageshack.us/a/img854/157/oscarprogramming.png

I don't understand the Pre-Infusion instructions.  If you press the Coffee Button all it does is keep the pump running and if you have a full tank of water it could cause the pump to run for a long time.  Are you suppose to do this with the water tank out of the machine?

I read the instructions over and over and thought the same thing.  I tried it (with the tank in) and it did NOT work on my machine.  Just kept the pump running.

I received this answered from NS:

"That is a feature on a capsule version of the machine. It is not needed or available on standard Oscars because the pre infusion happens automatically. "

So the Oscar does have a pre-infusion?  I have seen a lot of posts on different coffee forums and I thought the consensus was that the Oscar didn't have a pre-infusion function.  Hmmm I wonder how it works on the Oscar exactly?

I think they call that 5 seconds of non dripping prefusion.

I believe the hype of preinfusion on the Oscar is nothing more then the preinfusion all vibe pumps give, they take time to ramp up to full pressure where as a rotary pump is almost instantly at the pressure set. I have only seen Oscar promoted as having preinfusion on vendor pages and in the forums.

The Oscar has preinfusion

The on/off switch and the brew button are the same part #

The switch has a plastic slider and plastic return arm between the locking ratchet of the on/off main portion of the switch. the plastic slider and arm are on a greased track to engage one side of the main switch within the distance of about 2.5mm or .1".
this engagement point is half way through the full travel of the locking ratchet of the switch.

The brew switch on one side opens the three way to the brew path and closes the ThermoSyphion path , the other side goes to the brain to power the pump.

So if the plastic slider is functional , the arm can break the grease can harden , you must push the button in far enough to to engage the .1" engagement zone of the slider ,
too little nothing happens ,
to far it engages the pump.

It get's worse , you can go past the engagement point and rattle the brain's transformer as it tries to engage the R3 relay to power the pump... do this to often and you be in the market for a new brain box. So any rattling noise at the right rear , push on thru and lock the pump on.

Wait there's more,  the HX has a volume of 110 ml , this = 3-5 seconds of usable preinfusion , after that it's pushing steam and risking  vapor lock... engage pump until only water exits .

Use no portafilter until you get a feel for what's going on

the switch is a pain to replace and usually with break upon removal
the brain is $$

ENJOY

Just for fun, here's a video I found of somebody programming the Timed-Dosing on an actual CAPSULE Oscar...
