When the burner of your boiler is turned off, and within the anticipated time frame, the gas valve does not close, Vaillant F62 error code displays. Such a delay is dangerous because it means that there could be leakage or continuous tempering of gas inside one’s combustion chamber leading to collection of unburned gas.
Causes of the F62 Error Code
Faulty Gas Valve: A defective or sticking gas valve can prevent it from shutting off promptly. This may be as a result of wear and tear or any mechanical failure.
Electrical Faults: The function of the valve may be affected by electrical circuit problems regarding its control system like wrong wiring or problematic printed circuit board (PCB).
Control System Errors: Delay in closing down may be caused by incorrect commands being issued from the boiler’s control system including its PCB to the valve.

Immediate Action: For this reason, when experiencing problems with a gas valve, it is necessary to switch off your boiler and call an engineer who has been registered for Gas Safety. Do not attempt fixing this problem yourself.
Professional Inspection: A competent technician is needed to examine electrical components linked with a gas valve to identify what causes the delay. Gas valves operation should be tested during inspection, as well as checking upon cables; moreover PCB should also be evaluated.
Repair or Replacement: Due to diagnosis results there might be various solutions such as repairing malfunctioning valves, rectifying electrical connections among others which requires fixing boilers control systems. Consequently, these repairs are supposed to be done by experts alone for safety and correctness reasons.
System Check: As soon as all necessary repairs have been completed and replacements carried out where applicable, the technician must ensure that all other parts are functioning normally without any potential danger. In particular one should make sure that no leaks are observed along with some other security worries while that this shut-off mechanism works properly.
