Fleck 5600SXT - RC?

[can00k]

Hi everyone,

I purchased a tank with a Fleck 5600SXT a few years ago and it's been working great until the past week. The display used to cycle through the time and a number that I assume was the amount of water to pass through the tank until the next regeneration cycle. However, I don't believe a regeneration cycle has happened for the past week or more, and the display only shows "RC - 125" and the number continues to grow. I know RC stands for reserve capacity, but the manuals I'm reading all show that this should only be displayed if I'm reconfiguring the device, which hasn't been done in years.

Should I force a regeneration cycle or is there something else I should check?

Current info that I had documented previously:

155 ppm = 155 mg/L = 9 grains per gallon
capacity = 15.0 x 1000 (15000 grains)
hardness = 9 grains per gallon

DF = G
VT = df2b
CT = Fd
NT = 1
C = 15 x 1000
H = 9
RS = SF
SF = 10
DO = 7
RT = 2:00am
B1 = 10
BD = 60
B2 = 5
RR = 10
BF = 2
FM = t0.7

"RC - 125" and the number continues to grow. I know RC stands for reserve capacity, but the manuals I'm reading all show that this should only be displayed if I'm reconfiguring the device, which hasn't been done in years.

I would expect the unit to regenerate at 2AM. If the display said RC-something the day before also, then I don't know.

Is the water still soft? I would wait until tomorrow. I would expect a count-down number then. Is the time of day clock indicating OK? Probably does not matter if it is an hour or so slow due to daylight savings time.

I noticed this the other day, I was also expecting it to regenerate itself but it hasn't yet. I may try to start a manual regeneration tonight before bed.

Is the clock working?

So yes, I would do a manual regen. I might also consider a soft reset or a master reset. The service manual tells you how.

You will need to re-enter your settings for either.

The clock wasn't working, the unit didn't seem to respond to any button pushes either. I was going to do a manual regeneration, but first I saw that it was plugged into an extension cord that had nothing else in it, so I unplugged everything and plugged the Fleck back into the wall directly.

Now the screen isn't coming on at all. Do I have a defective unit?

Did you test the outlet to confirm it is receiving power?

Maybe. Do Bannerman's test. The power supply could be going bad. I think it is 24 vac nominal. There is a control board which is replaceable. Not cheap. Not outlandish.

Did you try the master reset?

Unit has a 10 year warranty from the place I bought it. I contacted them and they'll be taking a look at it for me. Will report back what they find.

The outlet definitely has power, but it may be the AC adapter. The unit I have has the Fleck embedded into it so it's not easy to get to the back of it.
