Free-up cable for measuring
Remove switch for handle heating 2 carefully with a
small screwdriver from tank.
Remove carefully locking hook 3 on plug of the sec-
ond handle with a screwdriver and pull the plug up-
ward.
Test contact pins in plug
These must be clean (free of corrosion), exposed
and at the same height. The contact pins of the plug
or the sleeve are to be secured with a hook against
accidental loosening. If the hook slips out of its posi-
tion the contact pin will move toward the bottom of
the housing and can no longer make contact.
Before you replace the contact pins in the housing
you need to open the hook 4 a bit using a small knife
or similar tool.
