Got to a WD440 today with 1,2,4 flashing.
Nowt at all to do with dryer side this time, but the supressor low resistance internally. Changed assembly now fine.
Might save time in the future to check that one….and soz if its already been noted 😉 .
I,ve got one took out one shot stat took apart clean out fit new normal tests all ok stat lasted one wash NTC reads 28K but only now displaying error code 12&4 I did once have an NTC fail mechanically (fell to pieces) and on ordering one to try, I see that the part number has been changed could there be a known fault with these that is intermittant?
