Further resets will not help and may be blocked anyway. Leave the boiler alone for now.
Note what code showed before L5. That earlier code points at the real fault.
Is the gas on, does the hob light, has the prepayment meter got credit? Is the outside condensate pipe frozen? Warm water, never boiling, can clear a frozen pipe.
Reads the fault history to find the code behind L5, then fixes that fault.

On many Ideal boilers, L5 means the boiler has locked out several times within a short spell, often five times in around fifteen minutes. After that, it refuses more resets for a while. The code is a warning that an underlying fault keeps returning.
L5 is not the fault itself. It follows another lockout, such as a failure to light. The real cause is whatever made the boiler lock out in the first place. Your manual will explain the exact rules for your model.
We often see L5 in Darlaston on cold mornings when someone has pressed reset over and over. Moxley and Kings Hill have plenty of Ideal combis with long condensate pipes outside, and a frozen pipe can trigger repeated lockouts.
No. It is the boiler protecting itself from repeated failed starts. Should you ever smell gas, leave the property, do not use light switches and call the National Gas Emergency line on 0800 111 999.
It depends on the model. The manual gives the wait. Even then, the original fault will still be there.
It depends on the cause underneath. Often it is something simple like a frozen condensate pipe.
