Please check for info. How to empty the washing machine lint filter

No filter to be cleaned in the machine. There are however small wire mesh filters in the screw on connectors that connects the water hoses to the machine at either the tap side or where it are connected to the machine inlets. Unscrew the hoses from the tap and machine inlets and check both hose ends if the wire filters are not to clog up over time resulting in slow water filling of the machine. Remove carefully and clean with a nylon brush. Replace again.

the valve filter is blocked up

turn off the hot water supply and remove the hoze from the machine end valve inlet
in the inlet is a small filter remove it and clean it

if its not too bad perhaps the valves solinoid coil has shorted turns
and wont open fast or fully
check the outlet preasure of hot water from the hoze to a bucket
see it flows fast ..

For the slow water issue, you will need to replace the water inlet valve. Here is a link to the part.
Could you describe the noise and where it is coming from?
