1x flash on the start pause button

stripped out door mech all looks and seems to be working ok including light
stripped all sump pump and hoses cleaned them all out including the plastic ball in the sump hose.

blew clean the pressure hose reconnected all

old pump was melted on coil and was showing below 150oms So fitted new sump pump Askol replacement bayonet type UN51203

still got same error beeps and flashes
and washer will still not drain
is this the triac or pcb
as stated everything else works it goes through full cycle from filing up to agitating water into spin mode but will not drain.
have even cleaned out drain hose and all external piping but to no avail.
any help would be appreciated as this has me stumped

Melted coil on pump has sure to have blown the pump triac on the board. Take a close look on the board for a square black triac with its top blown off!

Hi many thanks for getting back to me have replaced pump but still no joy have stripped board out there are 3 black boxes seem to be 12 volt converters all seem OK ran meter continuity through them all and all seem OK the coil on the board has seen better days but after clean up it seems OK no melting of coil visible or dry joints and all four wires are still connected to board again ran meter over board and it seems OK but I have left my other meter at work and I can not check resistance on them all, All I can do is put it back, I did think it might be board but wasn’t sure any other help is appreciated many thanks martin
regards
Tony
