There’s nothing more frustrating than pulling your Flymo out for a quick mow—only to find it completely unresponsive. Whether you have a classic Flymo hover mower, a corded electric, or a modern battery-powered model, most “no start” problems can be solved at home with just a few tools and simple checks. This in-depth guide covers all the reasons your Flymo lawn mower may not be turning on, plus step-by-step instructions for diagnosis, repair, and reliable starts all season long.
Quick-Check: Why Won’t My Flymo Lawn Mower Turn On?
- No power to the mower (dead battery, unplugged, or faulty cord)
- Blown fuse in the plug or power socket
- Tripped circuit breaker or GFCI outlet
- Damaged, cut, or loose power cable
- Faulty on/off switch or starter button
- Grass or debris jamming the blade or impeller (safety cut-out engaged)
- Moisture or water inside switches or connectors
- Battery not fully charged, faulty, or incorrectly inserted (battery models)
- Handle safety lever or bar not engaged
- Internal wiring fault, motor issue, or worn brushes (older models)
1. Safety First: Prepare for Inspection
- Always unplug your Flymo or remove the battery before inspecting or cleaning any part of the mower.
- Do not attempt repairs with wet hands or on wet grass.
- For corded models, check that the cable is fully removed from the socket.
- Wear gloves when handling the blade or underside of the mower.
2. Power Source and Fuse Checks (Corded Models)
- Plug in a lamp or phone charger to the same outlet to check if the socket has power.
- Check the fuse in the plug—UK models use a 3A or 5A fuse. Replace if blown.
- Inspect the extension cord: Use only a heavy-duty, outdoor-rated cord with no cuts, nicks, or frays.
- Test a different outlet: If your socket or extension cord is dead, try a different circuit.
- Reset GFCI/trip switches if they have triggered (often after rain or a power surge).
3. Battery, Charging, and Insertion Checks (Battery Models)
- Charge the battery fully—many battery Flymo models will not run if the charge is low, or if left idle over winter.
- Re-insert the battery—remove and firmly click it back into place. Ensure all contacts are clean and dry.
- Try another battery if available, to rule out battery failure.
- Check for flashing lights on the charger or battery—red or orange may signal a fault or over-temperature condition. Let cool and try again.
4. On/Off Switches and Safety Levers
- Press and hold the starter button (if equipped), then pull up the handle lever/bar. Many Flymo models require a two-step start for safety.
- If the lever or bar feels loose, sticky, or doesn’t spring back, inspect the cable and connections for kinks or disconnections.
- Spray a small amount of contact cleaner or light oil on the lever pivot to free it up if sticky.
- Check all connections and wires to the switch for damage or corrosion.
5. Check the Cable and Internal Wiring
- Look for visible damage, cuts, or kinks in the cable. Replace immediately if found—damaged cords are a fire and shock hazard.
- Wiggle the cable gently at both the plug and mower ends while trying to start—if the mower powers on/off intermittently, the cable may have a break inside.
- On older mowers, the internal wiring or motor brushes may wear out. These can sometimes be replaced—consult a service center if in doubt.
6. Blade, Impeller, and Obstruction Checks
- Always disconnect from power first!
- Turn the mower over and check for packed grass, twigs, or string around the blade or impeller.
- Remove all debris—any jam can trigger a safety cut-out and prevent the motor from starting.
- Spin the blade gently by hand (wear gloves)—it should move freely.
7. Moisture and Water Ingress Issues
- If the mower was recently washed, left in rain, or stored in a damp shed, let it dry completely before retrying.
- Use a soft cloth to dry plug ends, battery slots, and switches.
- Allow the mower to sit indoors for several hours to ensure all moisture is gone—many Flymo models have moisture-sensitive cut-outs.
8. Motor and Internal Faults
- If all basic checks fail and the mower is still dead, the motor brushes may be worn out (especially on older Flymo models).
- Some models have user-replaceable brushes; others require service center repair.
- If you hear humming, see smoke, or smell burning, unplug immediately—internal motor failure may have occurred.
- For persistent issues, contact Flymo customer support or a qualified repair shop.
Preventive Maintenance for Reliable Starts
- Inspect and clean cables, plugs, and battery contacts regularly
- Store mower in a dry, sheltered space away from moisture
- Charge battery models monthly, even over winter, to prevent deep discharge
- Clean grass and debris from blade, impeller, and deck after every mow
- Check for updates, recalls, or service bulletins from Flymo for your model
- Replace worn blades and keep vents clear for optimal airflow
Frequently Asked Questions (FAQ)
Why won’t my Flymo mower start after winter storage?
Most likely, the battery is flat, the cable or fuse is faulty, or there is moisture in the switch or connections. Charge the battery, dry all connections, and check for blown fuses.
Can a bad extension lead stop my Flymo from working?
Yes. Damaged or undersized cords cause voltage drop and prevent the mower from turning on. Use only heavy-duty, outdoor-rated cables.
What should I do if my Flymo clicks but doesn’t run?
Likely a jammed blade, debris under the deck, or a failing motor. Remove obstructions and try again. Persistent issues may require service.
How can I tell if my battery is faulty?
If the battery will not charge, shows error lights, or works in other tools but not the mower, it may need replacing. Always test with a second battery if possible.
When should I call for repair?
If all cables, fuses, switches, and batteries check out but your Flymo is still dead, contact Flymo support—especially if your mower is still under warranty.
