F3 fault on my Grundfos CU200 – outside Globe AZ. The wellis 8 years old, 500’ deep, 2 GPM (less now) and set up with Grundfos 3 SQF-3pump, CU200, IO 101, solar, plus grid power on a manual spring timer (usesometimes at night or cloudy days). No prior problems.
Odd thing: the fault occurred using the timer Saturday(cloudy). But over the days since, turning on the timer no longer results in fault indicators - thebox just stays unlit. However, whenthe solar panels come online it DOES display the fault indicators (such as when I reconnected them after closing upthe boxes). However, “000” is displayed briefly and I thought I saw the rising arrows(for pumping), then it switches to fault light/F3. Also, once when I turned on grid power it did the same littledance, but not now – no display. BTW the “3” looks like an upside down “F” –top LED segment missing. I have also turned off and on the IO 101.
Opened the two boxes with my handyman and nothing obviously amiss. Cleaned out a few dead spiders – mostly in the IO 101.
Do the changing display suggest the CU200 goingbad? (Shouldn't the F3/fault always be on with a pump problem?) Anyonein the Phoenix/Globe with expertise re: Grundfos SQFlex? How to get a “knowngood” CU200 without wasting $800 if it’s not the problem? Any advice?
Context: There is also a shared well (7 homes), but it went dry amonth ago – local mine has diverted City waste outflow water from ourcanyon a few months ago. 8 years ago, pumping therested well on grid power (fixed 2.5 GPM) the CU200 would start up at 320-330watts. That was constant until last summer when the water was diverted. The laststartup was at 360 watts, implying about a 60-foot ground water drop. It maydrop further and kill the well, so I am on the fence about expensive repairs. Weare about to drill down the shared well, fingers crossed. I have 90 youngfruit, nut and olive trees.

- #2The control box has an F3 where the volts are usually at. I don't know what that means, or how to fix it.
Welcome to the forum.
According to Grundfos, 'F3' means no contact to the pump. Hopefully that is just a bad connection or bad cable. In addition to checking the cable and the connection in the CU200, check the end cover (with socket) on the pump. The F3 fault could also mean a defective CU200 or defective pump.

I believe so (but have no actual experience with that pump or controller). One thing a controller does is protect the pump from running when the voltage or current is not sufficient.... the pump can be burned out if the voltage or current is not sufficient. If you are sure of your power source, you can give it a try. If a cloud comes by and drops your solar output, you may damage your pump.
--vtMaps4 X 235watt Samsung, Midnite ePanel, Outback VFX3524 FM60 & mate, 4 Interstate L16, trimetric, Honda eu2000i - #4The Grundfos SQLFlex takes a wide range of AC or DC input because it uses a rectifier to get DC and then uses that DC to power an inverter that delivers exactly what voltage and frequency the pump motor needs to use up the available power.
I do not think that the inverter is in the pump (I may be wrong), but rather in the controller. That means that bypassing the controller is very likely to damage the pump beyond repair, as the pump would want to run on correctly pulsed AC.0·Share on Twitter - #5
The SQF Package has a standard SQ pump inside that runs from AC only. The majority of SQ pumps are 240vac. The SQ pump does have electronics inside for soft starting and detecting that water is there. A few other things also. If this was bought as a package the SQF, then you can feed 240 in to test it without the SQF electronics (you need to disconnect them!!!). The other thing is your well could be dry.The Grundfos SQLFlex takes a wide range of AC or DC input because it uses a rectifier to get DC and then uses that DC to power an inverter that delivers exactly what voltage and frequency the pump motor needs to use up the available power.

E-mail [email protected] - #611 days and he is not back and maybe he called the folks that installed the pump. Maybe he did what alot of people in my state are doing and called a water truck.....
The problems I have seen with this controller were from lightning. Another good reason to run a straight type SQ pump at 240VAC or the shallow 120VAC SQ pump.'we go where power lines don't' Sierra Mountains near Mariposa/Yosemite CA

- #8Hi Don,
We did fine this winter with a last rain in May topping off our 16,000 gallon tanks. The rainfall was about our lowest as we get between 30 and 60 inches a year. After 4 years of drought we had a seasonal total of 15 inches of rain and 1/2 inch of snow.
There is a hurricane heading off the Baja coast that could bring us a shower if we are lucky. You never stop learning and we discovered that there can be 35 gallons in the roof to tank pipes that can condense off the roof some nights up here. We would hear it in the downspout for years. Last year we started saving the first 15 minutes of rainfall in a garden only tank and it really was an eyeopener.
The state is giving people a tank and 2,500 gallons a month and helping with re-drilling for folks. I like the rainwater much more and it always tastes great to drink. It makes great ice cubes for adult beverages.....
You take care and say Hi to Karen !'we go where power lines don't' Sierra Mountains near Mariposa/Yosemite CA
