    Why will my Mi-T-M HS Pressure Washer engine not start?
    • J
      Juan OwensAug 20, 2025
      If your Mi-T-M Pressure Washer engine won't start, the issue may stem from engine problems or frozen components. Refer to the Engine Manual included with your unit for engine-specific troubleshooting. If any part of the unit is frozen, allow it to thaw completely before attempting to start it. Freezing can cause excessive pressure buildup, potentially leading to serious injury.

    What to do if my Mi-T-M Pressure Washer has low or fluctuating pressure?
    • J
      Jeffrey WaltersAug 21, 2025
      If your Mi-T-M Pressure Washer exhibits low or fluctuating pressure, several factors could be responsible. Check for kinks in the water inlet hose and remove them. Inspect the water inlet screen for obstructions, and clean or replace it if necessary. Ensure all water intake connections are tightened to eliminate air leaks. Replace with a high pressure nozzle, or move the adjustable grip on the dual lance counterclockwise to high pressure. Also, examine the spray nozzle and valve assembly for obstructions or damage, cleaning or replacing as needed. If the pump packings are worn, replace them. Finally, check the unloader/bypass valve for proper operation; repair or replace it if necessary.

      If the detergent is not siphoning in your Mi-T-M Pressure Washer, ensure the detergent strainer is fully submerged in the detergent solution. Check the strainer, hose, and nozzle assembly for any obstructions, cleaning or replacing them as needed. Also, verify that the detergent adjusting knob is in the open position. Refer to "Cleaning w/ Detergents" for more information.

    What to do if water is leaking at the safety relief valve on my Mi-T-M HS Pressure Washer?
    • D
      Dr. John CollinsAug 26, 2025
      If water leaks from the safety relief valve on your Mi-T-M Pressure Washer, it indicates a potential issue with the unloader, pressure switch, or the safety relief valve itself. You should detect and correct any unloader or pressure switch problems. If the safety relief valve is defective, replace it immediately. Never operate the unit without a functional safety relief valve, as this can lead to an explosion.

    What to do if my Mi-T-M HS burner runs erratically?
    • P
      petersnyderAug 29, 2025
      If your Mi-T-M Pressure Washer burner runs erratically, it could be due to several reasons: water in the fuel oil, a dirty fuel filter or fuel water separator, a dirty fuel nozzle, an improper air adjustment setting, or a malfunctioning fuel pump. Replace the fuel filter or drain the fuel water separator, drain the fuel tank and replace with clean fuel. Replace the fuel filter element and the fuel nozzle. Adjust the air and replace the fuel pump.

    Why is there no discharge at the nozzle when I squeeze the trigger on my Mi-T-M HS Pressure Washer?
    • G
      George HubbardSep 1, 2025
      If there's no discharge at the nozzle when you squeeze the trigger on your Mi-T-M Pressure Washer, the cause might be an inadequate water supply. Make sure the hose is 3/4" in diameter and the incoming water supply is turned on.
