Jet brewer is displaying a "Low Pressure" message

The "Low Pressure" message isn't a measure pressure, but an approximation based on how the brewer operates during heating cycles.  If the Jet registers too much overshoot during a heating cycle it interprets the overshoot as a lack of water/low pressure. 

• “Low Pressure” is triggered by an overshoot in temperature. It is not triggered by a pressure measurement. 
• Check the “Set Power” setting within Setup. Make sure it matches the hardware confirguration  I.E. if you have a 5.6kW Jet check the brewer is configured correctly.  If you have wall voltage lower than 210v Marco recommends lowering the "Set Power" to the next lower setting.
