BoilerFaultCodesYour boiler is operating normally and showing that the system pressure is at a healthy level while the water is warm.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Normal pressure, system warm/hot. O.K.
What causes this fault?
This is not a fault, but rather a status reading showing the current water pressure within your central heating system. The numbers indicate that the internal pump is active and the water has expanded slightly as it heats up, which is exactly how the system is designed to function. As long as the display remains in this range while the heating is on, your boiler is operating perfectly.
You may notice these readings more frequently during winter when the heating is running constantly and the system water remains hot.
