Worcester Bosch 30cdi boiler with intermittant EA fault.? - worcester bosch ea

Already has more than 2 years and a fine of 6 EA went very intermittent fault then months.Started more frequently.
Worcester Bosch Engineers, said the low gas pressure of 32 mm pipe underground had supplied to the boiler and improved in recent Transco pipelines on the way back, but the blame more from EA.
In all 8 or 9 visits from Worcester Bosch, but not avail.Coming 26/11.

Always check the pressure in the boiler with all gas appliances in homes with gas and fast that the pressure to say goodbye low.When Transco pressure increase.

Without doubt, these boilers operate under low pressure?. The code at about 5:00 sometimes without other gases.
Who ideas.

Thankss

Chris.
