Hello J Arnott,
Sorry to say I'm here in the USA.. and I could not easily get a similarly designed model to reveal itself (for me) to gain a better understanding of your
Hotpoint LFT114... (nor could I pull a FREE copy of your user manual (without registering or otherwise exposing myself to cyber-freaks (sorry)).
Regardless of the specifics.. suffice it to day your machine is NEW enough to be quite visible and relevant...
I looked over the LFT114
HA...
Display board... £42.93
(there are many
LFT114
And your trouble description was quite excellent in detailing
as SEQUENCE failure of your control modules...
Although it is possible to repair these things ... it seems you have several PCBs (printed circuit boards)... replacement is usually the first best GUESS (looking at the back () side would not hurt anything)...
I have rescued many a circuit board by simply "de-soldering"...
then re-soldering a connection...
(special care, skill & tools required... not tough nor expensive).
You description and troubles indicated the beeps & lights missing: is a clear indictment of your "
DISPLAY board"...
A reminder... don't touch any PCB you value without first grounding your hands (professionals use STATIC WRIST STRAPS... CHEAP (unlike circuit boards) & available EVERYWHERE).
Also...
Take lots of pictures of EXACTLY WHERE every wire comes from... (look them over
BEFORE you get in trouble).
Be patient & FORCE
nothing.
and of course... be safe (
REMOVE POWER).
Comment me back BEFORE you guess wrong... (I'll try to help) .
