Pro Tip: The Stiebel Eltron 550457 Mixing Valve for Mini-E water heaters is no longer available as a standalone replacement part. The mixing valve must now be purchased as part of the appropriate assembly. Before ordering, have your Mini-E water heater’s complete model and serial number available to help confirm compatibility and identify the correct replacement assembly.

For assistance locating the proper assembly, chat online or call 888-503-7937 Mon–Fri, 9AM–5PM EST to speak with a ProDryers customer service representative.
