HI,
I purchased a Barista Express 870XL secondhand from Facebook marketplace & have been having some issues with low/no pressure. Initially the pressure was okay but have noticed recently that the pressure has become significantly worse often not reaching above the pre infusion level. I have tried the following resolutions but to no avail. I am unsure whether it is a solenoid valve or water pump issue so am seeking some guidance from those who know more.
- Deep clean/Descaling x 2 cycles - Low Pressure continued
- Deep clean of grinder and have adjusted the grinder on a number of occasions - Low pressure remains
- Purchased a distributor & palm tamper - Low Pressure remains
- Varied the amount with the Dual Wall Double Cup 16-18g - Low Pressure remains
- Test shot with dual wall portafilter - When running water through the dual wall double cup portafilter, low pressure remains & a large volume of water stays within the portafilter, with the machine creating a lot of noise. See attached youtube video for demonstration.
Any help would be really appreciated.
Thanks,
Ben
