The same issue came up on mine. The same message I was able to have samsung send someone from samsung to repair it they did say that it could have happened at the manufacturer, adding a bad peace to it after they replace the same piece you are doing had no problem except my apartment has low water pressure of 35 psi that it has to be at 60 psi to be able to clean the heat exchange I had to buy a water pressure booster and connected it to the cold side so each time it goes to clean the heat exchange it has no problem with it
Glad to hear it's working well for you now! Good point about needing sufficient water pressure, others on Reddit found that as well. Did you see if the replacement part they installed for you was the same design?
