If your espresso machine is not drawing water from the reservoir it could be either a water issue or an intake hose issue. Potentially a combination of both.
  1. Start by checking your water quality. If your water is too pure and does not contain sufficient minerals, then the unit may struggle to draw water into the boilers. The PID will read "H20" if water is required.
  2. Verify that the rubber/plastic water intake line is arranged such that it is fully submerged and touches the bottom of the reservoir.
