Hi ,do you know if the pressure is above 1.2? If there is an I (info button) pressing this should bring up pressure or turn power off then on
Customer: replied 1 year ago.
Pressing I button gets no response at all , just continues to read "Con". If you turn it on and off it starts by giving the temperature of 64 degrees then goes back to read "Con". The pressure has been increased and should be ok . Thanks

Hi , con is listed as no communication with the main board. Check all electrical connrctions are tight and secure. .
