Bruce- finally got around to swapping the high limit switches (didn’t realize they also doubled as thermostats). The steam light turned on and the steam boiler is functional!
Interestingly after I swapped the high limit switches the boiler temperature was not going up on the PID. I had to again reset the high limit switch that originally came from the steam boiler and then the brew boiler began showing an increase in water temp. So looks like you were spot on for recommending I look Into the high limit switch! I’m going to order a replacemeI’m going to order a replacement I limit switch since the one that I just swapped is already over 10 years old. Thank you again for you help I was about to give up hope on ever having a latte again :) > On Feb 25, 2021, at 4:53 PM, Nicholas Majka <[email protected]> wrote: > > Thanks Bruce!
