Echo ES-250 Error Code Won't Start: How to Fix It

Q: How often should I replace the spark plug on my Echo ES-250?

Replace the spark plug annually or after every 100 hours of use, whichever comes first. If you use the blower frequently or notice hard starting, check the plug every 25 hours.

Q: What type of fuel should I use in my Echo ES-250 blower?

Use fresh unleaded gasoline with a minimum 89 octane rating mixed with high-quality 2-cycle oil at a 50:1 ratio. Never use straight gasoline or old fuel that's been sitting for more than 30 days.

Q: Why does my Echo blower start but then die immediately?

This usually indicates a fuel delivery problem, often caused by a clogged fuel filter, dirty carburetor, or incorrect fuel mixture. Check these components after ensuring you have fresh fuel and a clean spark plug.

Q: Can I use automotive oil in my Echo 2-cycle engine?

No, never use automotive oil. Only use oil specifically designed for air-cooled 2-cycle engines, as automotive oils don't burn cleanly and will damage your engine.

Abstract

When your Echo ES-250 leaf blower won't start, it's typically caused by a fouled spark plug or stale fuel mixture. This common issue prevents the engine from igniting properly, but it's usually an easy fix you can handle yourself with basic tools and replacement parts.
