I HAVE BIPAP SYNCHRONY ST ERROR E48 IS APPEARING WHEN I START MY MACHINE

I suggest you first to check if there is any errors memorised in your washing machine, then we will know what is, a malfunction or improper use of the machine.
So, how to make a rapid reading of alarm codes, see below:

First, appliance must be in normal operating mode (e.g. during the execution of the washing programme, I suggest reading the alarm exactly when the washing machine working).

Press START/PAUSE and nearest option button simultaneously for at least 2 seconds:
The LCD display shows the last alarm.
The alarm continues to be displayed until a button is pressed.

Let me know exactly error code (Could be: first digit always "E", than following two numbers) if you read the alarm on display.
