On the BlueStar TOUCH induction cooktop, the manual gives Er47 the same cause as U400: the cooktop is not connected to the electrical network. The fix it gives is to check the connection and reconnect. BlueStar cooktop display What to do when Er47 shows on the cooktop ### Kind of code Boards and communication The touch board and the power board under the glass lost track of each other, or one failed its own start-up check. A power dip, a ribbon or harness pulled loose when the top was fitted, or moisture from a boil-over is ruled out before a board is replaced, and a cooktop that keeps heating while this code shows is switched off at the breaker. ### Usually leads to Touch control repair Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting. ### Shows up as Cooktop Controls Unresponsive Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element. ### Make BlueStar A Pennsylvania maker of open-burner gas cooking, sold in the US as pro rangetops with griddle and charbroiler options. ### Source BlueStar TOUCH induction cooktop use and care manual, Troubleshooting BlueStar TOUCH induction cooktop, model BSP36INDTOUCH.

Switch the breaker off and have the connection checked. If it comes back, it needs a visit. ### Why does BlueStar give Er47 and U400 the same meaning? The manual lists both as a connection problem with the supply. We treat either as a reason to check the wiring first. ### What if the connection is fine and Er47 stays? Then the cooktop's internal boards need testing on a visit. ### Is Er47 on a BlueStar TOUCH induction cooktop a wiring issue I can fix myself? BlueStar gives Er47 the same cause as U400, a cooktop not connected to the electrical network. Checking and remaking that connection is electrical work, so leave the breaker off and have it done by a qualified person. --- **[Read on the site: BlueStar induction cooktop showing Er47](https://cooktoprepair.center/error-codes/bluestar-er47/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
