According to most HEALTH authorities and the better pluming codes
a dish washer operating temperature for DOMESTIC shall be 140-160 degrees and for Commercial 160-180 degrees for sterilization in lieu of chemicals.
This is one of the reasons why commercial heaters have a much higher temperature range and why Holby tempering valves and anti scald devices have been manufactured.
On my installations using the higher temperatures I run a dedicated line to the pot scrubber/dishewasher and temper the water for the rest of the building.
Most health authorities will agree 125 DOESN’T KILL all the bacteria. Have a nice day
