Washing Machine Not Completing Cycle

Hi,

I have an LG WD-80130S (Intelo Washer 7,2kg), it started with this symptom some time ago, but was still usable until last week. In short, it does not wash through a single program, though it used to wash through the default cotton option, as long as no changes were made to default options. It starts the wash, putting water, detergint etc, and for no reason it will stop, and the pre-wash and timesave indicator lights start flashing. Resetting the machine (switch off and on at front panel) seems to let the cycle resume from where it stopped, but not for long. Sometimes it could take up to 8 resets before a load is complete. Please help, I'm at dire straights with a four month baby in the house.
Thanks and Regards.
