The frustration of a lawn mower that refuses to start, especially after being exposed to water, is a common issue many homeowners face. Whether it’s due to a sudden rainstorm, accidental submersion, or simply high humidity, water and electrical or mechanical devices are not a good mix. In this article, we’ll delve into the reasons why a lawn mower may not start after getting wet, how to troubleshoot the problem, and most importantly, how to prevent such issues from occurring in the future.
Understanding the Risks of Water Exposure
Water exposure can be detrimental to the functioning of a lawn mower, whether it’s a gas-powered, electric, or cordless model. The primary reason for this is the risk of electrical shorts or the rusting of metal components. When water seeps into the engine or electrical system, it can cause immediate damage, leading to starting problems or, in severe cases, render the mower inoperable.
Immediate Effects of Water Exposure
The immediate effects of water exposure on a lawn mower can vary depending on the extent of the exposure and the type of mower. For gas-powered mowers, water in the fuel system can lead to poor engine performance or failure to start, as water does not combust and can cause the engine to stall or not ignite. For electric mowers, water can cause short circuits in the electrical system, preventing the mower from starting or leading to dangerous electrical shocks.
Assessing the Damage
Before attempting to start the mower, it’s crucial to assess the extent of the damage. Check for any visible signs of water entry, such as rust, corrosion, or mineral deposits on the metal parts. If the mower has been submerged, it’s likely that water has entered the engine, fuel tank, or electrical compartment, which could necessitate professional repair or even replacement, depending on the severity of the damage.
Troubleshooting a Wet Lawn Mower
Troubleshooting a lawn mower that won’t start after getting wet involves a systematic approach to identify and possibly rectify the problem. Here are key steps to consider:
When troubleshooting, afety should always be the first priority. Never attempt to start a wet mower, as this could lead to electrical shock or further damage to the engine. Instead, follow these steps:
Step-by-Step Troubleshooting Guide
- Dry the Exterior: Use a towel or let the mower air dry to remove any visible moisture from the exterior. This prevents any further water from seeping into the mower’s internal components.
- Check the Air Filter: A wet air filter can prevent the engine from getting the air it needs to start. Remove, dry, or replace the air filter as necessary.
- Inspect the Spark Plug: For gas-powered mowers, a wet spark plug can prevent the engine from starting. Remove the spark plug, dry it, or replace it if necessary.
- Drain the Fuel: If water has entered the fuel system, it may be necessary to drain the fuel tank and replace the fuel with fresh, dry gasoline.
- Check for Electrical Issues: For electric or cordless mowers, inspect the electrical components for signs of water damage. Look for rust, corrosion, or burn marks that could indicate a short circuit.
Professional Repair
In many cases, especially if the mower has been fully submerged or exposed to a significant amount of water, it may be necessary to seek professional repair. A small engine repair shop or the manufacturer’s service center can assess the damage and provide a quote for the necessary repairs. It’s also worth considering the cost-benefit analysis of repairing versus replacing the mower, especially if the mower is old or the repair costs are high.
Prevention is the Best Cure
Preventing water exposure is the most effective way to ensure your lawn mower continues to function properly. Here are some preventive measures:
Storage and Maintenance
- Store in a Dry Place: Always store your lawn mower in a dry, well-ventilated area. This could be a garage, shed, or under a covered patio.
- Regular Maintenance: Regularly check and maintain your mower’s condition. This includes cleaning the mower after use, checking for rust or corrosion, and ensuring all covers and seals are in good condition.
- Use a Cover: When storing the mower, use a breathable cover to protect it from dust and moisture.
Protection During Use
- Avoid Mowing in Wet Conditions: Try to avoid mowing the lawn during or immediately after rain. Not only can this be dangerous due to slippery surfaces, but it can also lead to water exposure for the mower.
- Be Aware of Your Surroundings: When mowing near water sources like ponds or sprinkler systems, be cautious not to accidentally submerge the mower or expose it to excessive moisture.
Conclusion
A lawn mower that won’t start after getting wet can be a significant setback for lawn care and maintenance. Understanding the risks of water exposure, knowing how to troubleshoot the problem, and most importantly, taking preventive measures can help mitigate these issues. By storing the mower properly, maintaining it regularly, and being mindful of its operation in wet conditions, you can extend the life of your lawn mower and ensure it remains in good working condition for years to come. Remember, prevention and timely intervention are key to dealing with the challenges posed by water exposure to your lawn mower.
What are the common causes of a lawn mower not starting after getting wet?
The most common causes of a lawn mower not starting after getting wet include a faulty spark plug, water in the fuel system, and a short circuit in the electrical system. When a lawn mower is exposed to water, the spark plug can become damp or wet, preventing it from producing the spark needed to ignite the fuel and start the engine. Additionally, water can enter the fuel system and cause the fuel to become diluted, making it difficult for the engine to start. A short circuit in the electrical system can also occur when water comes into contact with the electrical components, causing a malfunction in the ignition system.
To troubleshoot these issues, it’s essential to inspect the spark plug and replace it if necessary. Checking the fuel system for any signs of water or damage is also crucial, and draining the fuel tank and replacing the fuel can help to resolve the issue. Inspecting the electrical system for any signs of water damage or short circuits is also necessary, and repairing or replacing any damaged components can help to get the lawn mower starting again. Regular maintenance, such as checking and replacing the spark plug, and keeping the fuel system clean and dry, can also help to prevent these issues from occurring in the first place.
How does water enter the lawn mower’s engine and fuel system?
Water can enter the lawn mower’s engine and fuel system through various means, including exposure to heavy rainfall, flooding, or even simple mistakes such as washing the lawn mower with a hose. When a lawn mower is exposed to water, it can seep into the engine and fuel system through openings such as the air filter, fuel cap, or spark plug hole. Additionally, water can also enter the fuel system through the fuel tank vent or fuel line, causing the fuel to become diluted and making it difficult for the engine to start. It’s essential to take precautions when operating a lawn mower in wet conditions and to regularly inspect the lawn mower for any signs of water damage.
To prevent water from entering the engine and fuel system, it’s crucial to operate the lawn mower in a well-ventilated area and to avoid exposing it to excessive water. Regularly inspecting the lawn mower for any signs of water damage and addressing any issues promptly can also help to prevent more severe problems from developing. Additionally, using a lawn mower cover or storing the lawn mower in a dry, secure location can help to protect it from the elements and reduce the risk of water damage. By taking these precautions, you can help to ensure that your lawn mower remains in good working condition and minimize the risk of it not starting due to water damage.
