Yes, it is possible to contact Freshwater and you will, if you persist, get to speak to someone. The instructions I was given with the softener are clear and straightforward to follow.
1) Set the time using the up/down arrows
2) Press and hold down th "P" button for 5 seconds. You then need to adjust the hardness, H -- xx, value to that for your water supply using the up/down arrows. (You can find out what value to set either by using the testing kit supplied or by asking your water supplier.)
Ah, BUT!
Mine seemed to work just fine for a while but then got into a mode whereby it recharged far too regularly using >25Kg salt tablets per month.
So, I thought it would be a good idea to re-check the hardness setting. Step 2) now produces a different display. No "H" anymore but instead:
1--- nnn where the nnn doesn't seem to relate to whatever water hardness value I entered. (This value is adjustable though using the arrow keys.)
If I press P again it steps the display to
2 -- mmm , again the number seems to have no obvious relevance.
Pressing P repeatedly gives 3 -- xxx , 4 -- yyy and then 5 -- finish
whereupon another press gets the time display back.
It is possible to chance the "finish" to another number and then another press of P gets me 6 -- finish.
It's hard to imagine that the control unit has failed completely but it clearly isn't working as it is meant to do. It rather sounds as though it has found its way into some exotic manufacturer's programming mode. (Oh yes, and I have tried power-cycling it with no obvious effect)
The advice I got from Freshwater was to replace the control unit - this at a price comparable to buying a complete new system. It was suggested to me that mine was "time-expired" and was due for replacement anyway. Obviously disregard the claims for a 30 year lifetime made on their website.
I guess that I have little to lose by turning off the control unit and recharging manually periodically? Or will that mean that the softener will be by-passed and my water will not be softened at all? The other "remedy" I'm temped to try is to set the 1 -- nnn value to "finished and see what happens. If that bears fruit, I'll re-post.
If I do replace it, I'll almost certainly choose a non-electronic, entirely mechanical model.
If anyone has any ideas or has had similar experiences, please let us all know.
