bush washing machine repair.

[dave 12345]

hi guys. i have a bush f721qb washing machine which i have replaced the door seal. so i have put it back together and all im getting is start light and stop lights are just flashing?

i also have another bush washer sa127qw which works fine. as both front panels are exactly the same i swapped the mainboard from the good one to the bad one and it works. no flashing lights. 

so i tried the bad one in the good washer and it works fine too???? but when i put oit back into the first washer same thing just flashing lights???

can anyone help with this?

Hi. I would check all of the connections and wires to the board in the first one.

yea have done that a few time now. like i said they both work in sa127qw. and the mainboard from the sa127qw is working on the f721qb. i am baffled???

Hello Dave. If a part doesn't work in one machine but it does in another then it's highly likely that it is the connections or wiring, especially if a replacement part works okay as you described. I honestly can't think of any other explanation.
