LPowners.org Tightening the boiler

by Bruce Colglazier Pappas

Tightening the boiler is not a repair to be undertaken by the faint of heart. There are a few potential complications. This file is for latter-model machines. NOTICE: Make sure the machine is unplugged from electrical outlet before proceeding. Refer to this parts list: Exploded View

Try fixes in this order (easiest to most complicated):

  1. Try tapping the flange (#7) with a flat punch to tighten it. You will most likely need to remove the heating element (#9) to do this properly.
  2. If that doesn't work, try tightening the flange with a custom DIY tool, an oil filter wrench, or a flange tool from Stefano. You need to secure the boiler to do this properly. I have a YouTube video where I strain heavily to tighten the flange. I did this to help my friend who has ALS.
  3. Finally, if the first two methods don't work, you need to replace the fiber gaskets (#4 & #6) in order to hold the boiler in place. Then you do the second method. I have a YouTube video on how to use gasket adhesive to make this work better. I'll post the video soon.

NOTE: #4/#6 gaskets come in two versions: narrow Euro and wide Pro. For Euros, use TWO P-4E. (For better grip on Euros, Stefano recommends using ONE narrow P-4E above the base and ONE wide P-4P below the base.) For Pros, simply use TWO P-4P.

The possible complications are:

  • Since you've tightened the flange, the heating element may not fit in the same position. You need to either re-bend the tube (#11) to accommodate its new position, or replace the tube.
  • If you remove the heating element, you'll probably need a new rubber gasket (#8) to reseal the boiler/heating element. This gasket flattens over time and often doesn’t work when reused.

Good luck. And report back on how things go for you.
