Fleck 5600SXT setting

[Monet33]

Need some help on the settings for my fleck 5600 unit that I had for about 3yrs now. It was working great but lately I have been seeing more water spots after washing dishes/pans and water doesn't seem as slippery as before. We are just 2 people using the water mostly for shower/dish washing/laundry and use about 5CCF per month or around 10-17CFper day. We have California city water that shows 234ppm hard water and we have some iron in our water as we have iron stains in our faucet and bathroom. I will be testing Hach to get an accurate reading on hard water. TIA

Haven't changed any settings but I have been seeing more water spots on my dishes and pans. I had it about 3 years and didn't see this issue before

Did you do the Hach 5-B testing? Test raw water and treated water. Cities report average hardness, and you want setting for worst case.

I would increase BF to 8. Keep some salt above the water line.

Are your house pipes galvanized steel? That could be the source of the iron.

Consider Barkeepers Friend for the sink and other rust stains.

Assuming your 5600 is equipped with a 0.5 gpm BLFC (brine line flow control), the current 5-minute Brine Fill setting, is causing only 7.5 lbs salt to become dissolved, which is insufficient to regenerate 24,000 grains Capacity each cycle. To regenerate 24K grains Capacity, will require 8 lbs or more salt.

Increase the Brine Fill setting to 6-minutes. 6-minutes BF X 0.5 gpm BLFC will cause 3 gallons water to enter the brine tank, which will result in 9 lbs salt to become dissolved.

Because insufficient salt had been utilized, additional capacity beyond that which 7.5 lbs could regenerate, had been depleted repeatedly.

After resetting the BF setting, as a 1X proceedure, perform 2 manual regenerations back-to-back. This will cause additional capacity to be regenerated beyond the 24K grains programmed, which will restore additional depleted capacity close to the full 32K grains, which will reduce the amount of hardness leakage passing through the resin bed.

Suggest performing the initial regeneration in the evening, about 2-hrs before you normally depart for bed. This should provide sufficient time for the 1st cycle to finish, so the 2nd regeneration cycle can be initiated just before you retire for the night. To permit time for sufficient salt to dissolve for the 2nd regen cycle, wait ~30 minutes after the 1st cycle has fully completed before intiating the 2nd cycle. Preferable if there is 0/minimal soft water utilized between the two cycles.
