No, not if your water blaster is cold water blaster.
Incoming hot water can damage your pumps seals. Generally waterblaster have a max inlet Water temperature of 80 degrees with a max pump temperature of 140 degrees.  If your pump exceeds 140 degrees the thermal relief valve will pop to protect your pump and it will need to be replaced.  However you can add an optional Hot Pump Upgrade to most available Water blaster in the market. Or buy a hot water blaster, that will give you a max inlet water temperature of 140 degrees with a max pump temperature of 190 degrees to be used with hot water.
