Electric pressure washers are convenient and efficient tools for cleaning various surfaces. However, they can sometimes malfunction and cut off unexpectedly. This guide will explore the common causes and solutions for electric pressure washers that keep shutting off.
Causes of Electric Pressure Washer Cutting Off
1. Air in the Pump
- Air trapped in the pump can cause the pressure washer to pulsate or turn off during use. This issue can be resolved by bleeding the unit to remove the air.
- To bleed the unit, assemble it without an extension cord, remove any connected nozzles, ensure the GFCI on the power cord is functioning, and turn on the garden hose while keeping the pressure washer off.
- Squeeze the trigger for about 3 minutes to allow water to flow through the unit at no pressure, then reinstall the nozzle and turn on the unit.
- This process helps to remove any air bubbles trapped in the pump, which can cause the pressure washer to cut off.
2. Leaks in the System
- Leaks in the high-pressure side of the pump can cause the pressure washer to turn on and off randomly.
- These leaks can be identified by inspecting the entire system for any signs of water loss, including the hoses, connections, and the pump itself.
- Fixing the leak, whether it’s a cracked hose, a loose connection, or a worn pump seal, will resolve the issue and prevent the pressure washer from cutting off.
3. Low Oil Levels
- Some pressure washers are equipped with low oil shut-down alerts, which are designed to protect the engine from damage.
- If the oil level is low, the engine will shut off automatically to prevent further damage.
- Regularly check the oil level and refill as needed to ensure the pressure washer operates smoothly without any unexpected shutdowns.
4. Overheating
- Electric pressure washers can overheat if used excessively or in hot environments.
- Overheating can cause the unit to shut off as a safety measure to prevent damage to the motor or other components.
- Ensure proper ventilation around the pressure washer and take regular breaks to allow the unit to cool down, especially during extended use or in high-temperature conditions.
