Ideal F1 Fault Code
What is An F1 Error Code?
The F1 boiler fault code appears on Ideal boilers. The fault code indicates low boiler pressure.
“The F1 error code is a result of low water pressure within your central heating system.” says Adrian Morgan our Managing Director & Head Plumbing & Heating Engineer.
The F1 error code can be resolved by repressurising your boiler.
If you need to repeatedly top up your boiler then you will need a leak detection plumber to help.
There are only 2 reasons why your ideal boiler will lose pressure.

How to Fix F1 Code On Your Boiler
1) Locate your boiler pressure gauge: The pressure gauge on an Ideal boiler is is most commonly an analogue gauge. The pressure gauge is located on the boilers display panel.
2) Check the pressure: The boilers pressure gauge should display the pressure as between 1 & 2 bar. An F1 error code is displayed if the boiler pressure falls below 1 bar.
3) Switch the boiler off: To turn your boiler off simply turn the mode knob control to OFF. Once the boiler is switched off allow 4-6 hours for the system to cool down.
4) Locate the Boiler Filling Loop: The filling loop is located underneath the boiler. The filling loop is a metal hose, with a valve at either end. The Boilers filling loop is used to connect your boiler to the main water supply.
5) Open the valves on the filling loop: Opening the valves on the filling loop allows water to enter your heating system, topping up the boiler pressure. You will need to open the valves by turning the handles or using a screwdriver, depending on the type of valves fitted. When the valves are open you will hear the sound of pressurized water.
6) Watch the boiler pressure gauge: When the boiler pressure guage reaches 1 bar, turn both valves back to their closed position.
7) Reset your boiler: Turn the boilers control knob to “reset” position, then to the “hot water” or “hot water and heating” position
You should now bleed your radiators. Check the boiler pressure drops again after bleeding the radiators. Bleeding process may reduce the boiler pressure. If the boiler pressure drops again, simply top it up again.
