Water naturally heats more than the optimal temperature. Diagnose the thermostat if heat occurs to confirm the problem or solve it.

A fixed thermostat maintains the desired temperature of the water as it cycles the nozzle on and off. Set the pressure washer thermostat at the desired temperature to work effectively. Don’t overthink the temperature of water increases & decreases. Decrease the output of heat of a burner nozzle.

Nevertheless, a non-adjustable thermostat in a pressure washer causes a different problem. The burner nozzle fires non-stop so that the water temperature increases at a consistent rate. In this case, utilize a safety switch that controls overheating. In this case, the safety switch turns off after the water temperature is preset.
