How to Troubleshoot: Ryobi Pressure Washer Pump Not Working

Symptoms of a Ryobi Pressure Washer Pump Not Working

There are a few different symptoms that can indicate that your Ryobi pressure washer pump is not working properly. These include:

The pressure washer is not producing any water or is producing very little water.

The pressure washer is making a loud whining or grinding noise.

The pressure washer is leaking water from the pump or other areas.

The pressure washer is overheating.

Troubleshooting a Ryobi Pressure Washer Pump Not Working

If your Ryobi pressure washer pump is not working, there are a few things you can check to troubleshoot the problem.

1. Check the water supply:
Make sure that the water supply to the pressure washer is turned on and that there is no blockage in the hose.
2. Check the pressure switch:
The pressure switch is a small valve that regulates the flow of water to the pump. If the pressure switch is stuck open or closed, it can prevent the pump from working properly. To check the pressure switch, turn off the pressure washer and disconnect the hose from the pump. Then, use a multimeter to check the resistance of the pressure switch. The resistance should be between 50 and 100 ohms. If the resistance is too high or too low, the pressure switch needs to be replaced.
3. Check the pump:
The pump is the heart of the pressure washer. If the pump is not working properly, it will not be able to generate enough pressure to produce water. To check the pump, remove the inlet and outlet hoses from the pump. Then, turn on the pressure washer and listen for the pump to start. If the pump does not start, or if it makes a loud whining or grinding noise, the pump needs to be replaced.
4. Check the hoses:
The hoses on a pressure washer can become damaged over time. If the hoses are damaged, they can leak water or prevent the pump from generating enough pressure. To check the hoses, look for any cracks or leaks. If you find any damage, the hoses need to be replaced.
5. Check the oil level:
The pump on a pressure washer requires oil to lubricate the moving parts. If the oil level is low, the pump can overheat and damage the seals. To check the oil level, remove the oil fill cap and look at the oil level. The oil level should be between the full and add marks on the dipstick. If the oil level is low, add oil to the pump until the level reaches the full mark.

Preventing Ryobi Pressure Washer Pump Problems

There are a few things you can do to prevent problems with your Ryobi pressure washer pump.

Use the right type of water:
Do not use water that is too hot or too cold. The ideal water temperature for a pressure washer is between 50 and 100 degrees Fahrenheit.

Do not exceed the maximum pressure rating:
The maximum pressure rating for your pressure washer is printed on the pump. Do not exceed this pressure rating, as it can damage the pump.

Clean the pump regularly:
The pump on a pressure washer can become clogged with dirt and debris. To clean the pump, remove the inlet and outlet hoses and flush the pump with water.

Store the pressure washer properly:
When you are not using the pressure washer, store it in a cool, dry place. Do not store the pressure washer outdoors, as it can be damaged by the elements.

By following these tips, you can help prevent problems with your Ryobi pressure washer pump.
