Brew Chamber Tension Adjustment
•
When adjusting the tension on the brewer, add full shims (K011950) or half shims
(K011191) between the T-bar and the H-frame, as illustrated below. These shims must be
added one at a time. Do not add several shims at once as the tension may be
increased too much.
In most cases, this simple procedure is enough to stop the leaking. However, if the brewer
still leaks at this point, repeat the procedure and add one more shim (start with one half
shim – if that’s not enough, remove the half shim and add one full shim).
•
Turning the T-bar should be avoided and should only be done as a last resort. If
the brewer tension is still too loose after installing two full shims, remove the two shims
and only once they are removed should you turn the T-bar one rotation clockwise.
•
If the wiper is hitting the coffee paddy as it moves towards the left, this indicates that the
brew chamber is not rising high enough. Either something is interfering with the upward
motion of the chamber, or the chamber tension is too tight.
•
If the tension is adjusted properly and the brewer is flooding, do not tighten the brew
chamber even more. Increase the bottom pause, lower the water temperature or replace
the filter screen. If the problem persists, check the brewer to make certain there is no loss
of vacuum, usually caused by a cracked brew chamber or cylinder, a worn or scored
cylinder, or a worn Teflon seal.
