## How to Fix a Pressure Washer: Troubleshooting Common Issues and Getting It Running Again
A pressure washer that suddenly loses power or sprays weakly can ruin a weekend of cleaning. The good news? Most problems are simple to diagnose and repair at home. This guide walks you through the most **common pressure washer problems** so you can get your machine running again fast.
### Start With the Basics: **No Pressure or Weak Spray**
Low pressure is the number one complaint. First, check your water supply—a kinked hose or closed spigot starves the pump. Inspect the **inlet filter** for debris and clean it. A worn or clogged **nozzle** is another frequent culprit; swap it out or clear the blockage. If pressure still lags, air may be trapped in the line. Squeeze the trigger with the unit off to bleed the system.
### **Motor Won’t Start or Keeps Cutting Out**

If your electric unit is silent, verify the **GFCI outlet** and extension cord gauge. For gas models, check the **spark plug**, fuel level, and **oil sensor**. A tripped **thermal overload** means the motor overheated—let it cool for 15 minutes. Dirty **carburetor** jets often cause stalling; a quick clean restores steady running.
### **Pulsing or Surging Water Flow**
Pulsing usually signals **air leaks** on the suction side or a failing **unloader valve**. Tighten all connections and inspect O-rings. If the issue persists, your **pump** may have worn seals.

### **Water Leaking From the Pump**
Leaks around the pump point to damaged **O-rings** or a cracked **pump head**. Replacing seals is cheap and usually solves it. Freezing temperatures can crack the manifold—always store your unit indoors or use **pump antifreeze**.
### **Detergent Not Dispensing**
Check the **soap nozzle** and **detergent siphon tube** for clogs. Thin the detergent if it’s too thick, and make sure the **filter** at the tube’s end is submerged.
### **Frequently Asked Questions**
**Why does my pressure washer lose pressure after a few minutes?** Usually a clogged nozzle or overheating motor. Clean the nozzle and let the unit cool.
**Can I fix a pressure washer myself?** Yes—most issues involve nozzles, filters, O-rings, and spark plugs, all DIY-friendly.
**How often should I maintain it?** Flush the system after every use and change pump oil annually.
