Check for kinks in the water hoses - if they're ok turn off the hose taps, remove hoses and check the plastic filters in the valve inlet connection. You will need a pair of thin pliers to grip the filter tab and pull it out. Clean any debris off with a toothbrush, rinse and reinstall in valve. Check the cold tap and hose by turning off the tap and disconnecting the hose from the machine, hold it over the sink or bucket and turn the tap on just a fraction to start with to see if water is getting through, if it is then open it up a bit more to make sure it is flowing freely, if that is OK then replace the hose connection and check the solenoid on the valve with a multimeter. Washer Dryers have a triple valve on the cold side, one is for the wash and rinse, one for the fabric conditioner and one for the condenser.If the solenoid or valve is faulty it is not repairable, replacement is the only option.
Check the pressure switch -the system that determines correct water level in the drum. Its a round item about 3 inches across with several wires connected, it sits under the top cover. Its an air operated switch which tells the machine water has reached the correct level. Disconnect the thin rubber pipe from the switch and blow down through it to clear any blockage. Switch itself may be faulty but its more likely the pressure pipe or the vessel attached to the other end of the pipe is blocked.
