I know this thread (and machine!) are very old, but my Homark Compact SE4400 wash motor died on me a while ago. The motor either ran really slowly and stopped, or jammed completely, despite having power and buzzing.
Being quite handy I took the thing apart, and it turned out to be the bearings on the motor which were ruined by a small water leak and jammed. After searching ebay I found some of the correct size (626ZZ 6mm inside (shaft) diameter x 19mm outside dia x 6mm depth), fitted them, and it works a treat for the cost of £5.70 ! I hope this helps somebody.
