The snow has finally melted and you're excited to do some outdoor spring cleaning. You take aim at the winter gunk with your power washer and nothing happens. If your power washer won't start after winter, you're not alone. We have plenty of explanations to account for your pressure washer not starting, which is why we created the Repair Clinic troubleshooting guide. Sometimes a gas pressure washer won't start after sitting simply because the gas has gone bad. In that case, you might not have to buy any new parts. Also, maybe you have corrosion on the spark plugs (another easy fix). The best place to start is our list of symptoms. From there we can help you diagnose the problem and make sure you're buying the right part for your model. Watch our installation videos to get the job done correctly the first time.
