If Q1316 is shorted e~c that would explain why the motor is on. I would replace it, Q1314 is likely ok.
The KA is larger, you need to measure the original to see which will fit the pads.

Would this be ok to use as an alternative if needed for q1314

Thanks.
My thinking is that when q1316 shorted it would have taken out Q1314
Because the emitter and collector shorted on Q1316
If I replace Q1314 and doesn't work it would be handy to have on hand to replace it
Could you advise of some suitable compatinle replacements please that is available on ebay or aliexpress. Thanks
Thanks

Go to EBAY, then type DTA143X, There is a ad for 5pcs X DTA143X 340t-23 The picture shows DTA143XKA
All you need to do is measure the case on the original to know which part to order. They are electrically the same, just the foot print is slightly different.

Q1316 likely shorted do to high current in motor, maybe the mechanism jammed causing the motor to stall and draw excessive current
