[RE-wrenches] CU 200 error

[frenergy]

Wrenches,

        I have been asked to repair a Grundfos SQ installation for our area Land Trust.  Pump is not pumping and the controller (CU200) is throwing a code of: F3.  The manual says loose wires, bad connection, failed CU200 or failed pump.  I'm looking for more experience than mine in these matters before I drive the 3 hour round trip out there for the repair for: most likely issues, tests to conduct, tools, spare parts (controller??)......

Thanks in advance,

Bill Battagin
