Don't worry if the door latch on your washing machine seems
loose, this is normal. The door latch is designed to move so that
the locking mechanism in the washer can grab onto the latch.
If the latch were rigid, the lock mechanism would not be able to
grab the latch properly, causing check code dC/DC.
Don't book a repair or service for a loose latch unless you are
experiencing another issue or check code.

A 5E or 5C error code indicates that the washing machine has
detected a drainage issue. The most common reason for this
error is a blocked filter or a kinked drain hose. You should also
check that the drain hose has been installed properly and clean
the hose thoroughly to remove any blockages that may be
preventing your washing machine from draining properly.

our washing machine has different compartments for different
washing aids (for example detergents, washing powders,
bleaches and fabric softeners). Make sure you add the correct
type of detergent to the correct compartment when operating
the washing machine. There are also several different types of
detergent drawer, depending on your washing machine.
