If the flame effect on your Dimplex Indoor Fireplace won't start, there are several potential causes: * Ensure the mains plug is correctly plugged into the wall socket. * Verify that the water tank is full and there is water in the sump. * Check that the low voltage connector is properly connected. * Make sure the Transducer Unit is correctly seated in the molded recess in the sump.
