FP Smart Drive9 Excellence 7.5 - 7yrs old?

Part way through wash cycle, washer stops with intermittent beep. Re-balance clothes, gets through to end of rinse (empty bowl) and stops with a constant beep.

Light error is as follows (x is light on)
o o x o o x o x
First five are the wash cycles so middle green light is on
6th & 7th are Rinse, first orange light is on
8th is Spin, one & only red light is on.

All lights are steady on, no flashing. Have turned off & on, haven't tried starting again.

Any hints would be greatly appreciated.

Thanks
