Bosch compact dishwasher terminates program at water inlet.

[operator]

Hello board members
I require your experience and advice regarding a used Bosch Compact Dishwasher model SKS51E18EU bought recently.
The previous owner of 5 years mentioned an issue that it doesn’t drain at the end of the program, so restarting a new program clears this issue.
After good results for 7-8 cycles its behavior changed.. The ordinary program sequence begins: Drainage > Emptying all water in the system > and then the inlet pump starts taking in water, after ~15 seconds of water going in, the "check water" indicator turns on, and the program ends with a long drainage. total of 3 minutes since program execution
I checked:
• Different configurations of the in/out tubes in different angles while running
• The inlet filter - was clean
• Drainage filter + unscrewed some piece to reach the cog-wheel of the pump making sure there are no obstructions

After looking online I found that for similar cases some concluded this might be the inlet valve, before ordering a replacement I need certainty that this is the solution, that’s why I require your help.

Thanks in advance!

Does not sound like the inlet valve if it lets water in initially and then stops, its more likely to be the control board or switch to that valve, but in reality its impossible to tell from a distance, your best be is to call a service engineer.
