When I compare Brewtus and Iberital, first obvious difference is space.
Brewtus is so tightly packed, no wonder we all have similar problems after few years, mainly due to long term high temperature exposure.
in commercial machine, every cable that runs close to the boilers has protective sleeves.
I will keep in mind to search for a good source of some high temperature silicone coated sleeves and protect cables in Brewtus.
