worcestor junior 28i problem again

[mike2020]

hey guys

dont know if you remember me, i had a faulty pcb back in september

got an engineer out and he replaced it which cost £200 parts and labour

well im having problems again,

my other half tried to use the hot water this morning (the heating had been on for an hour) and after a few minuites the boiler goes to the fast red light, so she tried to reset it a few times and it wouldnt come back on, so she rang the engineer and he said that it wouldnt be the pcb as they never break after you put a new one in,

about 3 hours later she tried it again and it came back on, it stayed on for about 6 hrs and its gone off again fast red light, and when you reset it sounds like its coming on but no ignition sounds


any ideas?

Could be the water pressure sensor on its way out or blocked, had one like this the other week. Part cost around £23.
