Hey @rvitko, I just swapped my pump (6255) to a new tank and the control box melted a bit around the DC supply plug. I'm assuming a drop of water or something got in there as it's been running just fine for several years and it happened the night I moved everything around. I suspect that I can just buy a controller (7090.50) and power supply (6300.240) per your parts catalog, but the power supply is out of stock. Do you have any suggestions? Thanks!
