The S1 Cafe has never let me down!
I was experiencing problems with my S1 pump.
Thanks for the many posts and photo's. We are snow birds and have a S1 at both homes, both purchased used on CL. Upon return this spring to the NW the S1 was sounding funny. The pre-infusion would start and the pump motor would hummmmmm but something didn't sound right. After checking the "Operational Problems" forum I was sure I was going to be buying either a new bearing, new pump or motor or both.
Today I pulled the pump/motor assembly, neither showing any signs of corrosion but after removing the pump for the motor I found that the pump was frozen. I put in my vice with a set of soft jaws to protect the pump and tried to turn the pump gently with a crescent wrench. Applying gentle increasing force the pump shaft began to move. There were now alarming screeching or grinding noises so I started moving it back and forth gently. The shaft eventually began moving freely. I could move it with my fingers. I went back in the house fired up the S1, turned off the boiler and then checked to make sure the pump motor was working and it was. I turned it back off, reinstalled the pump and retried the pump/motor combo. Everything seems to be working now. My guess is that the S1 didn't like being ignored for 6 months.
I will put everything back to operational tomorrow and let you know how it's working
Did something go wrong? Ask about it here. Later report and document the resolution here including out of pocket costs for replacement parts.
