The service manual for your boiler here shows on page 52 "E133 indicates that the gas supply has been interrupted, ignition has failed or the flame has not been detected."

Start by checking the gas meter has not run out of credit if a pay as you go meter, if the meter is supplying gas and you have a gas hob make sure your getting gas to other appliances.

Restart the boiler and see if you can hear clicking when the boiler starts up when you turn on the hot tap.

Customer: replied 6 days ago.
No clicking
Expert:  JamesI replied 6 days ago.

Ok that sounds like an ignition fault, the clicking is a sign of the sparks being generated to ignite the gas to form the pilot light. Since there is no ignition no flame is detected and hence the E133 fault code.

The fault is a hardware fault (most likely faulty electrode or PCB), you will need a gas safe engineer to attend, strip the boiler down and replace the part, then recommission.

Is there not a button underneath the boiler to help ignite if it doesn’t come on or to ortomatically, I remember a potterton boiler I had that needed help sometimes?
Expert:  JamesI replied 4 days ago.

I imagine you are referring to a lockout switch but this boiler self resets on powering it off and back on.
