Subject: ROCKET R58, Brew boiler Temp problem
 

Hi I'm newbie,

I received my Rocket R58 last friday from www.espressocoffeeshop.com;
but i had Brew boiler Temp problem, i have email their customer service, but still waiting for answer.

see if anyone could help:

When machine is off, i connected PID to the machine, then turn on machine;
The display reads: Brew boiler temperature <60C; which the factory setting should be 105 C.

but i ignored, as i know i can re-set the temperature.

Then i followed on the program instruction, and set the brew boiler temperature to 105 C ( i also tried higher and lower);
after finish and exit, the screen always the same: Brew boiler temperature <60C (please see picture)

the boiler press gauge is about 0.8 bar and no higher. As i could not get the Pid right, so i did not use it even

any comments will be appreciated.

Bu

How long have you let the machine warm up?  My machine does the same thing at start up since the boiler is cold. As the machine warms up the temperature rises until thermal stability at 103 - 104 in my case. This takes about 15 - 20 minutes.

Welcome to CoffeeGeek!

The pressure gauge indicating boiler pressure monitors the steam boiler. It takes several minutes for both boilers to properly heat up. Only then boiler temperature of the brew boiler will be right, and the pressure of the steam boiler should rise to 1.2 to 1.4 bar.

the factory just called me and i'm testing, now the machine is on and they ask me to leave for 30 minutes;

by the way;
Is the initial PID screen reads OK (Brew boiler temperature <60 oC) ?
i have gone through the setting by holding about 7 seconds of OK button, and followed on;
i set Brew boiler temperature to be 107 oC; but the display always say: (Brew boiler temperature <60 oC)

Does it right?

I think its something wrong w you PID or the Blackbox. The read out is fast, after 5min is way over 60 from cold start.

Dumb question but have you followed the instructions and fill both boilers at the beginning?

I'm not talking about the plastic reservoir.  I'm talking about the inside boilers.  You need to start the machine and open the steam valve and wait for some water to get out.  But if you did that then something is wrong.

When you pull a shot is it hot?

Do you have a thermometer to warm your milk?  You could use this to get an idea are hot it is.

You think it's the PID that show a wrong temperature or it's just not working?

On mine the temp increase and i can see the evolution on the PID.

You may have to return it I'm afraid.
