Repair & Adjust

The linked pages in this section cover repair and/or adjustment of various components of the S1:

Boiler Repair - Covers disassembly of the steam boiler in order to replace the heater element
Expansion Valve - Shows how to replace and/or adjust the pressure at which the group boiler expansion valve pops open.
Motor Mount Replacement - How to remove and replace the motor mounts. A number of early adopters of the S1 had to do this in order to replace the original noisy mounts. New owners will probably never need to do this.
Heat Sensor R&R - How to remove and replace the heat sensor on the steam boiler. Several people who purchased their S1's since July 2005 have had a problem with the steam boiler over-pressure valve popped open and spewing hot water all over. This appears to be the fix.
Steam Arm R&R - How to remove and replace the steam arm. Original owners were provided with new steam arms to replace design deficiencies with the original arm. For newer users this may be of interest only if leaks or other problems occur as their S1 age.
