    <h1>hcklabxl : cleanup coffeemachine</h1>

 <p>cleaned up the &lsquo;group&rsquo; first time;</p>

<p>coffee temperature after cleanup rather low, so been investigating a bit and got to realise
the joint on &lsquo;heat exchanger&rsquo; was failing;</p>

<p>on Valente 1966 patent application is clearly noted the underside of the bell has to be sealed &ndash; so cut,drilled and sanded down a champagne cork to a +-3mm thick torus and added this in under the bell shaped heat exchanger element;</p>
