WT540 - mini load and short spin together with on/off light flashing?

Hi I have the WT540 machine and am having a problem when first turing the machine on, it lets me push the on button and pre set the machine for the required wash setting, then when I push the go button it automatically goes into a slow spin mode and three lights are flashing, the on/off button the mini load and the slow spin. I've let it run the course to see if this will rectify the problem but once the machine is re-set it does the same again. The water is only despencing through the rinse tray. Any suggestions? Ann
