New patient - an old Olympia Cremina needs TLC
This Astra Gourmet has a halting water flow.
Still trouble shooting the hydraulics.
Update - Interesting, this is a Pour Over machine so it does not have line pressure from the water source. The water is pumped into the system - eventually to the group to make espresso & when water is not being pumped a check valve (one way valve) prevents water from being pushed by pressure (heated water) back towards the pump. The one way valve has failed allowing the HX water to be drawn back into the pump & tank. This results in a dry HX - and when the barista tries to pull a shot - they get air instead of water for a shot or 2. Solution - replace check valve.
