well i would say the power supply on the board has very likely gone faulty

I would say concentrate on the components at the top right of the picture. measure any big resistors with low values and see if any are blown. the ones we are interested in are normally valued at 100 ohms or less

if you search resistor colour codes from google you will find how to read them

well with a rapid temp increase i would look at airflow first or is the heater on when it should be off ( poss relay stuck )

Dave

[electrofix]

first thing to check is the heater and on this unit its on the front of the motor

Dave

[electrofix]

no but if you can post some clear pics of the boards i will look at it

you will have to host offsite and post public links as there is a 2meg limit on here

I4 codes are all about pressure sw

I41 is no signal from pressure sensor

could just be blocked, some early units had a mod to stop blocking

if you get model and pnc the I can send you the info

well the last thing i would try is to read the coils from the pcb connector

if ok then i agree it does sound like a board as i cant think of anything else it can be

you could try one long shot

plug in one of your spare coils. dont put it in situe just plug in. turn on and see what happens.
does coil energise or does it go straight to fault

what i am wondering is how it senses coil. think it would only be able to sense it if its turned off. so what if the traic controlling the coil was leaky or shorted

hope you see where i am going

have sent you the manual as am not sure if you have it or not

Dave

assume you have checked the new valve has not failed

well cant tell if its an inverter motor or not

if not i would check motor connections and motor relay solder joints as a long shot

Dave

[electrofix]

check on the model number

I can see
bwe91484x k u
and
bwe91484x k uk N
which is yours ?

Dave

[electrofix]

have you gone into service mode as some error codes dont show to the user ?

Dave

[electrofix]

well went through service manual and the omit that one

assume the hinge you mean is mounted in the cooker body not the door, then there is a screw in from the side that holds them. that means if you have 2 ovens side by side you would have to remove one of the oven cavities to get the one in the middle. The one on the outside should be accessible with the side off.

so depends on whicjh hinge has gone and if you need to change both and if its the inner one I think i would say dont even go there

Dave

model no ?
