Ive got a fault code 3L showing on my boiler the appendix says its
"the tacho signal from the fan is not present during the preoperative or operating phase or there is no current of air after a certain time "
is this a common fault ?
is there anything i can try before calling someone out ?
is it expensive to fix?
does anyone know of a heating engineer in the Northallerton area who they would recommend ?

Tends to be new fan required.

Cheaper to call Worcester on fixed price repair than an independent rgi.

Presume occasionally it resets and runs fine other times it locks out.

its just stopped working this afternoon and the reset isnt clearing it
