Something I should have done is to put suppression on the filter pump relay contact. 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.

Alternative: put come concrete in the water. That dampens the pump like hell...
Joke.. honestly, it is a beautiful little tank Mick.
