Check that there are no kinks in the cold water fill hose and the waste water hose by pulling the appliance out slightly and untwisting any visable kinks or bends in these hoses. For more information on how to correctly install these two hoses, click the link below.
Also ensure that the waste water hose is not blocked by removing the waste water hose from the siphon connection, putting the end of the hose in a bucket and selecting the drain programme. If there is a blockage, water will not fill, or struggle to fill, the bucket. If a blockage is found, clean the waste water hose and siphon.
To check the water pressure, simply follow the instructions below.
