## **How to Fix a Pressure Washer: Troubleshooting Common Issues and Getting It Running Again**
A pressure washer that won’t start or loses power mid-job is frustrating. The good news? Most problems are simple to diagnose and repair at home. Below is a practical guide to help you **fix pressure washer** issues fast.
### **Why Your Pressure Washer Won’t Start**
**Check the power supply first.** For electric models, confirm the outlet works and the GFCI hasn’t tripped. For gas units, verify the fuel valve is open, the choke is set correctly, and the spark plug isn’t fouled.
**Inspect the fuel and oil.** Stale gas is a top culprit. Drain old fuel, add fresh gasoline, and check the oil level—many gas models have a low-oil shutdown.
### **Low or Pulsating Water Pressure**
**A clogged nozzle** is the most common cause. Remove the nozzle and clear debris with a wire or compressed air.
**Check the inlet filter.** A dirty garden hose filter starves the pump. Rinse it clean.
**Look for air leaks.** Tighten hose connections and inspect O-rings. Air in the line causes that sputtering, pulsating spray.
### **Water Leaking from the Pump**
**Worn seals and O-rings** allow water to escape. Replacing them is inexpensive and usually solves the leak.
**A cracked pump housing** may require a rebuild kit or replacement. If you’re unsure, this guide on how to fix pressure washer problems walks through each step with photos.
### **Motor Runs but No Water Comes Out**
**Prime the pump.** Hook up the hose, turn on the water, and squeeze the trigger until steady flow appears.
**Unclog the wand or hose.** Debris and mineral buildup block flow. Flush both with clean water.
### **Frequently Asked Questions**
**Why does my pressure washer keep shutting off?** Usually a low-oil sensor, a clogged fuel filter, or an overheating motor. Let it cool, then inspect each.
**Can I use regular garden hose water?** Yes, but always use the inlet filter to keep debris out of the pump.
**How often should I maintain it?** After every 50 hours of use: change oil, check the pump, and inspect nozzles.
