A fuse is an important safety component in any electric device, and pressure washers like the Sun Joe SPX3000 or Ryobi RY141900 are no exception. The fuse shuts off power to the washer if there is a surge or short circuit, preventing serious damage or injury. Knowing exactly where to find the fuse on your electric pressure washer model from brands like Sun Joe, Ryobi, AR Blue Clean, Powerhorse, or Excell is key so that you can quickly replace it to get your washer back up and running.
Key Takeaways:
- The fuse in electric pressure washers is crucial for safety during surges.
- Common locations for the fuse include the power cord plug, motor housing, and control panel.
- Less common positions may be inside the pump housing or integrated into internal wiring.
- Signs of a blown fuse include no power, burn marks or smell, and an indicator light.
- To inspect and replace, unplug, use pliers, check for damage, replace with an identical 5–15-amp fuse, and test for power restoration.
- Ignoring a blown fuse risks motor overload, electrical hazards, and equipment failures.
- Keep spare fuses for preventive measures and prioritize safety.

Common Electric Pressure Washer Fuse Locations
While fuse placement can vary depending on the specific pressure washer make and model, there are a few common locations where they are typically installed:
Power Cord Plug
Many pressure washers have the fuse built right into the power cord plug that connects to the outlet. Check the end of the cord where it plugs in for a small removable fuse cover; the actual 5–15 amp fuse will slide right out of this compartment. Having the fuse here makes it easy to inspect, test, and swap out if needed.
Motor Housing
Especially on larger or more heavy-duty pressure washer models, the fuse may be mounted directly to the 1350–1800-watt motor housing itself. Opening up the protective shell around the motor should reveal wiring connections and the fuse in a bracket. Sometimes accessing it requires undoing screws or panels.
Control Panel or Switch Box
For pressure washers with an electrical control panel or box with switches, the fuse is often located inside with the other components. The actual fuse holder may be on the circuit board or wired to it. Opening the box provides access; just be careful not to touch any live wiring.
Less Common Pressure Washer Fuse Positions
While less likely, it’s also possible the fuse may be installed in these other locations on some electric pressure washer varieties:
Inside the Pump Housing
Taking apart the pump cover and inspecting the pump wiring may reveal the fuse attached somewhere in the 1450–2300 PSI pump assembly. This placement is more common on smaller portable washers.
Integrated into Internal Wiring
Rarely, the fuse may be spliced right into the pressure washer’s internal wiring, so it won’t be obviously mounted to a particular component. Carefully following the wires may uncover an in-line fuse holder.
Tips for Locating the Fuse
If you aren’t having luck finding the fuse based on typical placements, use these tips to locate it on your specific model:
- Consult the owner’s manual: There should be a diagram indicating the exact fuse location. This is the best place to start.
- Search online: Check pressure washer forums or videos to see if anyone has posted the fuse location for your make and model.
- Visually inspect: Carefully examine the washer’s housings, cords, and components for any sign of a fuse holder.
- Look for labeling: Some manufacturers label the fuse holder to make it easier to find.
Knowing where the fuse is before you need to replace it saves huge headaches and downtime. Identifying the location and 5–15 amp size also allows you to purchase spare fuses to have on hand for quick fixes.
Signs Your Pressure Washer Fuse Has Blown
Some of the most common indications that the fuse on your electric pressure washer needs to be replaced include:
- No power: The washer motor won’t start or runs inconsistently. This is the clearest sign of a blown fuse.
- Burned smell or mark: You may notice an odd smell or see scorch marks around the fuse area, indicating it burned out.
- Indicator light: Some models have a light on the body that comes on specifically if the fuse is blown.
- Reduced performance: weak pressure output can also signal problems with the fuse.
Never ignore these signs or attempt to override the fuse; doing so can seriously damage the washer or pose safety hazards. Instead, promptly shut off and unplug the washer and replace the fuse.
Inspecting and Replacing a Blown Pressure Washer Fuse
When you locate the fuse, carefully check it for any signs of burning, broken metal, or a popped center. If it appears damaged, follow these steps:
- Unplug the pressure washer before fuse removal.
- Use pliers to grip and pull the fuse straight out of its bracket or housing.
- Inspect the metal contacts inside the fuse; any burn marks confirm it is blown.
- Insert a replacement 5–15-amp fuse of the identical type and amp rating.
- Return the fuse to the bracket and restore any housing or connections.
- Plug the washer back in and test. The motor should have power again.
Always keep spare fuses of the proper type on hand for your model. The amp rating, which is marked on most fuses, must match the original for safe operation.
The Dangers of Overriding or Ignoring Blown Fuses
It may be tempting to work around a blown fuse just to get your pressure washer running again, but this poses risks:
- Damaging the 1350–1800 watt motor by overloading it with too much current without fuse protection.
- Electrical arcing, smoking, or fire from live current exposure.
- Electric shock hazard from exposed wiring.
- Equipment failures from continued use without resolving the underlying electrical issues
Bypassing or ignoring a blown fuse is never recommended and can void your pressure washer’s warranty. The few minutes it takes to properly replace your washer’s fuse are well worth it for safety.
Conclusion
Knowing exactly where to locate the 5–15-amp fuse on your electric pressure washer allows you to quickly restore power and get back to washing when it blows. Check the power cord plug, motor housing, or control panel for the most likely placement. Use your owner’s manual or online resources to pinpoint the specific position if needed. With the fuse’s key role in protecting the washer, keeping spare fuses on hand helps minimize downtime.
