thats uncanny, just read through pages and pages of baxi faults to no avail after i couldnt get a narrow search to find anything.

ive not experienced any fault lights but i will try the sensor as recommended

thank you

just noticed the post is only a few below mine, sorry. instead of reading many old posts i will check for recent ones first next time
