The motor is receiving a start signal but not enough current to actually run. First clean the propeller and its shaft to rule out a partial jam; then, if the twitch continues, the motor (or its driver) has failed and needs a warranty replacement.<\/p>\n    <\/div>\n\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-info\"><\/div>\n        <h2>Twitching vs Jammed &mdash; The Key Difference<\/h2>\n        <p>A jammed propeller won&#8217;t spin by hand because debris or salt crust locks the shaft. A twitching propeller spins freely by hand but only twitches under power. The first is mechanical (clean it); the second is electrical (the motor or its driver board has failed). Telling these two apart is the fastest way to know whether you can fix it yourself or need a replacement.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-steps\"><\/div>\n        <h2>Rule Out a Partial Jam First<\/h2>\n        <p>1. Turn off and remove the S1 from the water. 2. Remove any hair, string, or leaves wrapped around the propeller shaft. 3. Rinse the propeller area with fresh water &mdash; saltwater crust can cause intermittent contact. 4. Spin the propeller by hand; it should rotate freely and smoothly. 5. Power on briefly and watch. If it now spins, it was a partial jam; if it still only twitches, move to escalation.

There is no user-serviceable fix &mdash; cleaning won&#8217;t help, and firmware resets don&#8217;t address it. Continuing to run the unit with a failed motor can overheat the driver and damage the control board further, so stop using it until it&#8217;s replaced.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-fix\"><\/div>\n        <h2>Warranty Replacement<\/h2>\n        <p>A single-propeller twitch or failure is covered under the Surfer S1 warranty.
