There could be several reasons for your pressure washer to surge when not spraying. Here are some possible explanations:
1. Air leaks: Check for any air leaks in the hoses, fittings, or connections. Leaks can disrupt the pressure flow and cause surging.
2. Pump issues: The surge could be due to a problem with the pump. It might be clogged, worn-out, or experiencing some internal damage. Inspect the pump and clean or replace it if necessary.
3. Unloader valve malfunction: The unloader valve is responsible for regulating pressure in the pressure washer. If it is not functioning properly, it can cause surging. Ensure the unloader valve is clean, properly lubricated, and adjusted to the correct pressure.
4. Water supply issues: Inadequate water supply or low water pressure can cause the pressure washer to surge. Ensure that the water supply is sufficient and the water hose is not kinked or obstructed.
5. Pressure regulator problems: Some pressure washers have a pressure regulator that may be causing the surging. Check the regulator and make sure it is set to the correct pressure setting.
6. Electric motor issues: If you have an electric pressure washer, the surging could be a result of electrical problems. Check the power supply, cord, and motor for any issues or malfunctions.
If you are unable to diagnose or fix the issue yourself, it may be best to consult the manufacturer's instructions or contact customer support for further assistance.
