  If your Hotsy pressure washer isn't producing hot water, here's what to check: * Make sure the burner switch is in the ON position. * Ensure an adequate fuel supply; refill the fuel tank using only recommended fuels. * The pump must be running before the burner will light, so ensure the pump switch is on. * Confirm an adequate water supply by fully opening the faucet, checking for any kinks or damage to the hose, using a 5/8 inch minimum hose, and checking for debris clogging the inlet screen. * Squeeze the trigger of the trigger gun, as water must be spraying for the burner to light.
