MOTOR PROBS????

My indesit w133s tried to scoosh water in the soap tray but instead of smoothly asd usual it intermitantly tried then stopped. The power light still comes on, flashes etc and an occasional motor noise whirrs a little but no action. Before I call a repair man does anyone know if this might just be the brushes or the motor, or is it fatal!!??!
The machine is around 6 years old and on average does around 2 washes per day.
Please help!!
