works for me

a diode is a one way device
will be lots of videos on utube how to test
but
set multimeter on diode setting
put meter leads on diode look ant the reading then reverse leads and they should differ greatly

if you get the same reading both ways it could be faulty. to be 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure unsolder from board and test again

is that stat von the side of the element ?

Dave

[electrofix]

have you put it into service mode and looked for fault codes

Dave

[electrofix]

1-3 is a pressure switch fault

assume the machine starts to fill then aborts

check for blockages in the pressure chamber and the hose that goes to the switch

Dave

[electrofix]

good scrounge

will be manufactured by Leibherr

Dave

[electrofix]

well always first to check is the stat
but looks like the relay has been getting warm and you could have done continuity on the overload

if its a stat its cheapish to repair

anything else could be difficult or expensive

Dave

[electrofix]

try changing the front stat which controls the heat returning to the element

to be honest if you reverse L and N it should make no difference. its an AC supply anyway. the board rectifies and smooths it to 320V DC or so and then put it through an inveter

its probably the power supply chip failed on the old board

Dave

[electrofix]

ok
did you disconnect heater just to make sure its not that

Check board for bulging caps

other than that gets harder. you can do silly stuff like check pump winding , motor coils etc but in the end you may well have to give up and scrap it

Dave

[electrofix]

well if you have not opened it then it may not be the spring

the spring has to attach both ends. onto the door frame and the hook, have had hooks break and where it attatches to the frame

so searching for a spring without checking could be a waste of time

ok off on a Uganda trip again

fly out Sunday night at 6 from manchester and return sometime on 25th

Dave

[electrofix]

dug around just in case you missed anything and no cant find a thing

like you i think is a board failure. looks like a 3 phase motor so likely the inverter has gone but the way they seal the board it makes it hard to find or look for blown components

Dave

[electrofix]

well the power supply still must have schottky diodes so look for them and test

it maybe the power chip thats failed

board listed in tech manual pictured below which has a D7 Diode

funnily I did one yesterday and board was like below

Dave

[electrofix]

if its the old type none electronic thermostat then t will probably cure it
