Prefilter change watermaker Spectra Ventura 200

A while ago i had changed the coal prefilter on the watermaker and cleaned the seastrainer inlet.

On the pictures you can see that this was necessary.
The watermaker had 250hours and was 6 months in use. The 5 and 20 micron filters need to be cleaned next.

The watermaker is still producing between 25 and 30 liters per hour depending on the watertemperature and voltage.
We are consuming around 100 liter per day and that means that we let the watermaker run around 4 hours per day.

It draws 10 Ampere so with our 200Ah charging per day over the solarpanels there is no need to run the engine at all.

I would now consider a bigger watermaker for the future but weight is another issue.

I have the gut feeling that some parameters are not set correctly since it still shows prefilters as good in the display panel.
