F21 error code is a motor related fault. But first lets try and reset the control unit and see if this clears it.

Turn the knob to the off position.

Turn the knob to the 6 o'clock position.

Wait for the start light to flash.

Press and hold the spin button.

While holding it, turn to the 7 o'clock position.

Release the spin button after a few seconds.

Turn the knob to the off position.

This should reset the control board, unless the control board is faulty.

Try it a few times as it's sometimes a bit difficult to get it to reset.

But if the E21 error code comes back then you need to remove the motor and check the carbon brushes at the back of the motor as they could have worn down casuing this fault.

Try that and see what you find and let me know.
