  If the water temperature of your Hotsy is too hot, it could be due to several reasons. Check the incoming water temperature and lower it if it's warm or hot. Also, verify the fuel pump pressure and lower it if it's too high. Inspect the detergent line for any air leaks, tightening all clamps and checking for holes. If the issue persists, the high limit switch (thermostat) might be defective and need replacement. Ensure sufficient water supply (check GPM to machine) and inspect the nozzle for obstructions or incorrect sizing.

  If you're experiencing low water temperature with your Hotsy, start by checking the fuel. Improper fuel or water in the fuel can cause this issue, so drain the fuel tank and replace it with the correct fuel. Low fuel pressure could also be the culprit, so increase the fuel pressure. Inspect the fuel filter for partial clogging and replace it if needed. Soot or lime buildup on the coils can also reduce heat transfer, so clean the coils accordingly. If the fuel pump is weak, check its temperature and replace it if necessary.

Why Hotsy 9460 Burner will not light?
- H
  Hunter BurtonAug 18, 2025
  If the Hotsy burner won't light, it could be due to several reasons. Start by checking if the fuel tank is filled with the correct fuel. Inspect the electrical wiring for any disconnections or shorts, ensuring all contacts are clean and tight. The on-off switch may be defective, so verify if electrical current is reaching the burner assembly. Also, a clogged burner nozzle or fuel line can prevent ignition, so clean or replace them as needed. Other potential causes include a faulty burner transformer (test for proper arc) or improper electrode setting (check and reset according to the diagram).

What to do if Hotsy machine smokes while burner unit is running?
- A
  Anna PetersAug 26, 2025
  If your Hotsy machine is smoking while the burner unit is running, or only at cold-start when the burner is off, several factors could be responsible. First, ensure that you are using the correct fuel and that there is no water in the fuel; if contaminated, drain the tank and replace the fuel. Check the air adjustment on the burner assembly and readjust the air bands. Inspect the burner nozzle for any blockages or if it's dirty; replace if necessary, verifying the correct size. Also, check for any obstructions in the smoke stack, such as insulation blockage or foreign objects.
