indesit wil153 -locked out-prolly board but will this work?!

indesit wil153, 5 yrs old.

intermittent odd behaviour over last 6 wks thats become pretty much contstant now.

wil153 has the pcb fascia control with the variable wash temp and prog knobs, and obv separate back module.

cust says:
regardless of which program its put on it will wash at the hottest setting and take about 30 mins, but then it will restart if she doesnt get the washing out within a few minutes of it spinning.

what it does: fills, drains, pumps, spins ok…

had a bitron white interlock, tried my test rold white one that didnt have any effect

when it isnt behaving, it will start as soon as the door is shut, as long as its on/off button is on, without pressing the start/pause. weirdly tho, when you change the temp knob it turns the machine off… pressing and holding the start/pause does actuate the all-led-lit cancelling process, but as soon as they go out it goes back to what it was doing. i know its probably the lower module, but before it wings its way to emw, in case its something else, as it sounds like its in a manufacturers test routine? does anyone know if theres a button process that can cancel a factory test routine??

cheers,

Rich

PS also would this in theory work – I have a lower module and control pcb off a bearing failure wil163 – 1600 spin version. this is the 1500 spin version. do they share the same motor, if so would i be able to turn this machine into a wil163 or is there other kit id need to put on it first. cust ideally wants a low cost fix, as selling house with appliances in it in 6-9mths time, otherwise i would have written it off by now 😉
