PE4551-M Unit heats continuously after

Posted by: Paladur August 09, 2020 11:31 am

Hello forum community,

as described above I have a PE4551-M machine.

The first error was the error alarm after about 10 minutes. Thereupon I exchanged the TB. Now the machine heats up constantly after 10 minutes and does not go back.

I have checked the following component.

- Heating TB 42 Ohm- both thermal fuses OK- both thermal sensors 85 kOhm at 28°C- steam heating 50 Ohm- both thermostats checked for continuity OK(values from Delonghi ESAM)At first sight everything seems to be OK. I am now at a loss.sad.gifDo
you have any tips for me what else it
could
be
? Greeting

Dear Paladur,
I’m experiencing the exact same behavior on my PE4551.
Did you find a solution?

Thank you.
