To get your pressure washer working again, check for simple issues first: ensure the water supply is fully on, clear any clogs in the nozzle or inlet filter, and check for kinked hoses. If the engine won't start, replace the old fuel, check the oil level, and inspect the spark plug.
If your pressure washer is not working, check the power supply first. Make sure the power cord is intact, the plug is properly connected, and the power outlet works. Also check that the switch is in the ON position and that no fuses, thermal protections, or safety switches have tripped.
The reset button on an electric pressure washer is typically located on the heavy-duty GFCI (Ground Fault Circuit Interrupter) plug attached to the power cord. It acts as a safety mechanism to shut off power when it detects electrical faults or current surges.
High-end commercial and industrial units are built to last. A single repair is often much cheaper than buying a new machine, and quality components make them worth fixing. Routine maintenance prevents bigger problems. Investing in repairs now can extend your equipment's lifespan and avoid costly downtime later.
Pressure washers generally last 3 to 10+ years, depending on the type and how often they are used. Rather than just years, they are primarily measured by hours of use.
As a general rule, you should repair your washing machine if it is less than 5 to 8 years old and the repair cost is less than 50% of the cost of a new machine. If your machine is older than 10 years or requires back-to-back, costly repairs, replacing it is usually the better investment.
A bad pressure washer pump usually shows clear warning signs: a severe drop in water pressure (acting like a basic garden hose), sputtering or pulsing while spraying, unusual grinding or knocking noises, or visible leaks of water and milky-colored oil from the pump body.

Second, overheating due to excessive time in the by-pass.
