Morning Morning,
Maybe an expert can help me here.
I bought a defective ESAM 5500 with the error message "General Error" or "General Alarm". I wanted to get the machine ready again.
A first measurement showed that a heating coil was interrupted by the thermoblock. I ordered this and exchanged it incl. upper limit switch and cable set and brewing piston.
Error pattern still "General Alarm".
During a test drive of the engine, I noticed that it was very loud and did not reach the top. With bridged door I could see that the trestle was locked on the threaded rod and was not pulled up. Probably in form of the heavy brewing unit.
I then replaced the gearbox and lubricated the brewing unit. Unfortunately the error remains.
About the current situation:
- The error occurs immediately after the power supply, no initialization!- In
test mode,
the machine initializes and sets the brewing unit to home position.
- All testable units work in test mode without further problems -
The temperature sensors give values of approx. 10kOhm (plugged on the board).
The thermoblock with sensor and switch and the gear with lower limit switch and reed board are
exchanged.
I have the feeling that the error is just stored in the memory, the machine doesn't even try the self-test at start. Is there a reset procedure besides the display test? I can't get into the menu of the machine because of the error message.
Measuring equipment and basic technical knowledge is available.
Many thanks for tips and remarks!
