EA
3002Hex foam excessive foam in
the cylinder during
boiling.
the formation of
foam is generally
due to the presence
of surfactants in the
water (lubricants,
solvents, detergents,
water treatment
agents, softeners)
or an excessive
concentration of
dissolved salts.
1. drain the water supply
lines
2. clean the cylinder
3. check for the presence
of softeners
(in this case, use another
type of water
or reduce the softening)
