Servis M range approx 3 years old ?

Don't know exact model, it's AA rated and has a 1400 spin. It's M6 something I think and is electrical in that it does not have the manual dials of old. It has neon blue lights. Washing machine stopped during cycle, now the start and stain action lights flash and the spin cycle light stays on permanently. Checked the filter and turned it on and off but lights still flash. It has been stopping mid cycle for months but I could reset it, open the door and close it quickly then press start again and it resumed the cycle.
