Richard Wolf recalls PiezoWave 2 Control Units with serial numbers 5000553232-5000553506 due to potential capacitor failure causing smoke and burning smell. Affected units may require replacement.
The high voltage capacitor may fail early in the product life cycle after delivery of surge voltages. When this failure occurs, the capacitor may produce smoke and a burning smell. In extremely rare instances a capacitor may cause a spark or excessive heat when an internal capacitor failure occurs.
