Pentair matertemp 400,000 BTU heater cycles on & off

My pentair matertemp 400,000 BTU heater cycles on and off before reaching desired temperature. I completely cleaned the DE filter and flow should not be an issue. When running the spa the pressure is 25. When running the cleaning system (polaris pop ups) the pressure is 30. Any tips on what might be the issue with the heater.
