The motor is small, but there is sometimes enough interference when switching it to crash the processor. I thought I might have been ok, but it appears that there is nothing built into the (encapsulated) motor. Put a 10n cap on the RUN pin. In my case that solved the issue. Volhout Alternative: put come concrete in the water. That dampens the pump like hell... Joke.. honestly, it is a beautiful little tank Mick. Edited 2024-05-16 05:00 by Volhout
