Re: zanussi zwf 1231w pcb
From where you bought it, was it second hand from another appliance? Then it would be programmed to work on the product that it came from, if your machine is not the same product code (see 9 digit PNC code + 01/02/03 etc) then theres a chance it won’t work.
There are unconfigured boards & configured boards available for these available to purchase but they are only configurable by Service Force Engineers with a laptop and the appropiate software (Sidekick).
