F2 on an Ideal Logic or Vogue usually means the boiler lit, or tried to, and then lost the flame.
In Coventry the everyday causes are outside the boiler. One is a gas supply problem, such as a prepayment meter out of credit or low supply pressure. Another, from December onwards, is a frozen condensate pipe. The less common causes are inside the boiler.
Code meanings vary between Ideal models, so check your manual too. If the boiler has run for years without trouble, a sudden F2 often points to one worn part rather than a failing boiler.
If the hob will not light either, it is the supply. Prepayment meters run out quietly, and an empty one gives exactly this fault.
A frozen condensate pipe outside backs up and stops the boiler. Warm water along the pipe, then one reset, clears most of them.
Hold the reset as the manual describes. If F2 returns, leave it off rather than trying again and again.
An engineer checks gas pressure, the flame sensing electrode, the fan and the flue. Usually it is a single part, not a whole boiler.
Expect one to two hours. The engineer tests the supply first, then the ignition and the sensor. The boiler is run again before they leave, to confirm the flame holds.
A photo of the display and the boiler label. Tell us when F2 first appeared and whether it clears after a reset. A fault that comes and goes is worth mentioning.
No. Losing the flame makes the boiler shut down safely. Smell gas? Leave the house, do not use switches, and call the National Gas Emergency line on 0800 111 999. A fault code is never a gas leak, but a smell always is.
Tell whoever changed it. Supply pressure after meter work is a known cause, and it is theirs to put right.
Ask for the Gas Safe ID card and look at the back, which lists what they are signed off for.
The part, and how long it takes to reach. A cleaned sensor is a short job. A replaced fan or gas valve is longer. You hear the likely cost before any work begins.
