EAM3300 general overhaul

Greetings,

almost 3 years ago my parents gave me an old (think 10 years or maybe even more) EAM3300.

Somehow I have the feeling that the freshly brewed coffee is no longer coming out of the machine very hot and so I thought about replacing the thermoblock including the brewing piston.

About a year ago I did the last big maintenance of the machine here and dismantled, cleaned etc.
At that time I already noticed that the whole thermoblock is already covered with lime and the screws could
not be opened to see inside.

The resistance measurement of the thermosensor showed at that time, however, that so far everything is ok, therefore, I have at that time

apart from

the exchange

because otherwise everything has worked perfectly.
Meanwhile the topic of the not so hot coffee doesn't really let me go anymore and therefore I would like to hear some opinions from you if an exchange makes sense in principle if the sensor
is still ok?
Since I know myself that a remote diagnosis is always as good as impossible, I would like to
clarify
the question
a little more
: My assumption is that perhaps a strong lime deposit has formed inside and the heat simply can no longer be transferred to the water so well? After all, the sensor sits on the outside of the housing and
is more likely to measure its temperature.
If I now decide to exchange the thermoblock including the brewing piston, maybe I can estimate if it makes sense to exchange other parts as well? Up to now no part had to be replaced (except of course seals) and still has
original equipment.
I look forward to your
opinions and tips. Greetings

Hi,

your EAM model has an aluminum thermoblock.
Of course you can
replace
th

e
thermoblock with the brewing piston 1:1, that would be the easiest way.
If everything continues to work, you normally don't need to renew anything - at most the hoses and the water filter,
you have already replaced
the seals
.
One could also
use an ESAM thermal block
instead of the EAM thermal block
.

There the water to be heated flows through stainless steel pipes and thus no longer comes into contact with the aluminium. In addition, the two heaters installed together have more

power than the EAM model.

However, you will have to

modify

the electrical

connection a bit.

If you have no electrical engineering training, leave

it alone or
give your machine a rest and get a more up-to-date
model. VGBernd

Hello, Bernd,

thanks for your feedback. I think then I will stick with the 1to1 exchange and do it in the near future.

Thanks also for the tip with the water filter. Makes sense in any case to also exchange this with.
