    Why won't the burner ignite on my Hotsy 1260SS when the trigger gun is open?
    • O
      oliviafernandezAug 13, 2025
      If the burner on your Hotsy pressure washer won't ignite when the trigger gun is open, the possible causes are no fuel, an adjustable thermostat set too low, a defective pressure switch, dirty or misadjusted electrodes, or no AC generator output. Replenish the fuel supply, raise the temperature setting, repair or replace the pressure switch, refer to the Oil Burner Manual provided with the machine regarding the electrodes, and check the AC generator.

      Logan ButlerAug 17, 2025
      If there is no water coming from the pressure nozzle of your Hotsy pressure washer, the possible causes include a clogged pressure nozzle, a clogged inlet water screen, or the pump sucking air. To resolve this, try cleaning the pressure nozzle, cleaning the inlet water screen, or filling the detergent container and checking for loose hose clamps or fittings.

      Jessica FosterAug 27, 2025
      If you're experiencing poor or no detergent flow in your Hotsy pressure washer, it could be due to a low detergent level, a clogged detergent screen, the detergent metering valve not opening, or a clogged pressure nozzle. To fix this, replenish the detergent supply, clean the detergent screen, check that the handle or knob is not slipping on the shaft, and clean the pressure nozzle.

Refer to the Oil Burner Section under Installation and use kerosene, #1 Grade Home Heating Oil, #1 or #2 Diesel Fuel. DO NOT USE GASOLINE.

Open and close the trigger gun several times. You can also repair or replace the defective unloader valve. Check the fittings, hose and trigger gun for leaks and repair or replace if necessary.
