So if you’re ready to get your pressure washer up and running again, let’s get started!
Why Pressure Washer Heater Not Working
Why Pressure Washer Heater Not Working
1. No power to the heater element
The most common reason for a pressure washer heater not working is that there is no power to the heater element. This can be caused by a blown fuse, a tripped circuit breaker, or a faulty connection.
To check for a blown fuse, look in the pressure washer’s fuse box. If the fuse is blown, replace it with a new one that is the same amperage as the old one.
To check for a tripped circuit breaker, look in the breaker box in your home. If the breaker that corresponds to the pressure washer is tripped, flip it back to the on position.
To check for a faulty connection, inspect the wiring between the pressure washer and the power outlet. Make sure that the wires are properly connected and that there are no loose or damaged wires.
2. Faulty heater element
If the heater element is faulty, it will not be able to heat the water. This can be caused by a number of things, including a crack in the element, a build-up of sediment on the element, or a loose connection.
To check for a faulty heater element, you will need to remove the element from the pressure washer. Once the element is removed, inspect it for any damage. If the element is cracked or damaged, it will need to be replaced.
If the element is not damaged, you can try cleaning it to remove any sediment that may be built up. To clean the element, soak it in a solution of vinegar and water for several hours. Once the element is clean, dry it thoroughly and reinstall it in the pressure washer.
3. Faulty control board
The control board is responsible for sending power to the heater element. If the control board is faulty, it will not be able to turn on the heater element.
To check for a faulty control board, you will need to test the board with a multimeter. To do this, connect the multimeter’s leads to the terminals on the control board. If the multimeter shows no reading, the control board is faulty and will need to be replaced.
4. Blocked water intake
If the water intake is blocked, the pressure washer will not be able to draw water into the heater. This will prevent the heater from heating the water.
To check for a blocked water intake, you will need to remove the inlet screen from the pressure washer. Once the inlet screen is removed, inspect it for any debris. If the inlet screen is blocked, clean it with a brush.
5. Low water pressure
If the water pressure is too low, the heater will not be able to heat the water. This can be caused by a number of things, including a clogged water filter, a restricted water supply, or a faulty water pump.
To check for low water pressure, you will need to check the water pressure gauge on the pressure washer. If the water pressure is below the specified range, you will need to troubleshoot the problem to find the cause of the low water pressure.
