As the topic was not very popular and I wrote to the mirror for some time, I decided to delete the posts and make one of them.
E8 - this is the lack of communication between modules as "peter falk" wrote earlier.
When the hob cooled down, the error disappeared, but the right cooking zones did not work.
It was possible to control the right fields, the vessel presence sensor was working, even after the program was turned off, the fields that were not working showed a warning about the hot field "H", even though the field was cold. I checked the cooking zones, resistance OK (30-60 ohm)
I found the damage on the so-called HOC2000 power module.
Two relays (blown contacts) responsible for the basic heating windings on the right panels were damaged.
Original RT314012WG 12V 16A / 250VAC relays have been replaced with HF115F-012.
After replacing the relays, the board works.
The error numbers that I found in the documentation
E-0 Config_Data_ALM_HC Wrong Configuration on HC / EEPROM checksum failure
E-1 TEMP_CoolBlock_ALM_L
E-2 TEMP_CoolBlock_ALM_R
E-3 Phase1missing_L Phase not detected on powerboard
induction Left
E-4 Phase2missing_R
E-5 CommErrorPowerBoard_L Internal Ind.Bus error / missing
connection / 12VDC or 5VDC missing
E-6 CommErrorPowerBoard_R
E-7 Temperature probe coil Error of min. 1 cooking zone (see alarm codes message def.)
E-8 Communication error to power board
E-9 Config_Data_ALM_HUI HUI received invalid configuration
