Common Reasons Your Generac Pressure Washer Won't Start

There are several reasons why your Generac pressure washer might be giving you trouble. Here’s a breakdown of the most frequent culprits: — Onslow County Sheriff: Jacksonville, NC Information

  • Fuel Issues: Old or contaminated fuel can prevent the engine from starting.
  • Spark Plug Problems: A dirty or damaged spark plug won't ignite the fuel.
  • Carburetor Clogging: A blocked carburetor restricts fuel flow.
  • Low Oil Level: Many pressure washers have a low-oil sensor that prevents starting.
  • Air Filter: A dirty air filter can suffocate the engine.
  • Pump Problems: Issues within the pump can sometimes prevent the engine from starting.

Troubleshooting Steps

Follow these steps to diagnose and fix the issue:

1. Check the Fuel

  • Is the Fuel Fresh?: Drain any old fuel and replace it with fresh gasoline. Use fuel stabilizer to prolong fuel life.
  • Fuel Cap Vent: Make sure the fuel cap vent isn't blocked. A blocked vent can create a vacuum, preventing fuel flow.

2. Inspect the Spark Plug

  • Remove and Inspect: Remove the spark plug and check for dirt, damage, or carbon buildup.
  • Clean or Replace: Clean the spark plug with a wire brush or replace it if necessary. Ensure the spark plug gap is correct.
  • Test for Spark: Reattach the spark plug to the wire, ground it against the engine, and pull the starter cord. You should see a spark.

3. Clean the Carburetor

A clogged carburetor is a common issue. Here’s how to address it:

  • Carburetor Cleaner: Try using carburetor cleaner to dissolve any buildup. Spray it into the carburetor intake.
  • Professional Cleaning: If cleaning doesn't work, you might need to disassemble the carburetor for a thorough cleaning or seek professional help.

4. Check the Oil Level

  • Oil Sensor: Ensure the oil level is at the correct level. Most pressure washers have a low-oil sensor that prevents the engine from starting if the oil is too low.
  • Add Oil: If the oil is low, add the recommended type and amount.

5. Inspect the Air Filter

  • Remove and Inspect: Check the air filter for dirt and debris.
  • Clean or Replace: Clean a foam filter with soap and water, or replace a paper filter if it's too dirty.

6. Check the Water Inlet Screen

  • Clogging: A clogged water inlet screen can reduce water flow and affect the pump's ability to prime, indirectly impacting starting.
  • Clean the Screen: Remove and clean the screen to ensure proper water flow.

Advanced Troubleshooting

If none of the above steps work, the problem might be more complex:

  • Pump Issues: A faulty pump can create excessive resistance, preventing the engine from turning over. Contact a professional for pump repair.
  • Engine Compression: Low engine compression can also prevent starting. This usually requires professional diagnosis and repair.
