Had machine for over 1 year with no problems. Recently a carpet remnant was washed and ever since we occasionally get water leaking from the dispenser draw. Is it likely that the filter has become blocked so that the water does not dispense quickly enough and then occasionally leaks from the dispenser. I appreciate any advice with regard to cleaning out the filter (if this is the problem), as I have had the back off of the machine and there appears to be some heavy duty white plastic clips which are very difficult to remove. Any advice much appreciated.
