Miele Dishwasher F70 (Waterproof) Error: Circulation Pump Seal (#6195751)
Quick Answer: The F70 error code (or 'Waterproof Fault' message) on a Miele dishwasher means water has leaked into the bottom stainless drip pan and lifted the styrofoam safety float. The most common leak sources are the Circulation Pump Seal Kit (#6195751) or the Heater Pressure Switch (#6996820).
⚠️ Why the Drain Pump Won't Stop Running When Switched Off: Just like Bosch's E15, Miele's F70 Waterproof system forces the drain pump to run continuously as long as the styrofoam float in the base tray is raised!
