Baxi 105e 60 fault

[adferguson]

Hi

I have been having a 60 fault with my boiler
The plumber swapped the pump, fitted a new aav, and had the system cleaned, flushed, inhibitor and a magna clean installed.
The system has been full bled but yet the fault still happens.
When the bleeding screw on the front of the pump is opened there is a hiss of air and then all is fine no need to even reset the fault.
Last year I had a new pcb, gas valve, both diaphrams and thermistors replaced.
The plumber is stuck for ideas.
Please HELP
