Good Day All! Here's hoping you can help!
When using the hot water spout on Barista Express the water flow is very intermittent with the water spiting everywhere!! I have carried out all of the cleaning cycles including the vinegar flush, hoping this would help but it didn't seem to. Prior to this occurring, the safety valve was replaced as it was leaking and after checking and reinstalling any tube ties, the problem keeps occurring. With the machine opened up, I can actually see the air travelling within the tube supplying the hot water spout. To add to this the water flow through the group head also appears less after the valve being changed over.

Many thanks in advance for guidance offered.
