There are two issues affecting the Expobar Brewtus IV-R.
- Explosive steam release and venting
- Water leak at internal connection point
While warming up, the machine will occasionally release steam. (This minor venting is expected.) The problem is that the machine now builds up pressure and releases an excessive amount of steam that won’t abate. See video below.
Video: Explosive Steam Release and Venting
In addition to venting steam uncontrollably, the machine leaks when power is off and components are cold. It stops leaking after powering on and warming up. Based on this behavior, it appears that a connection is slightly loose. When warm, the materials expand and prevent leaking. When cold, the fitting loosens and water can escape.
When enough water has gathered, it starts draining out and onto the counter.
