Customer Question

Hi, I have a Spaform Lyon 4000 which keeps showing FLO which shuts it down. If i tap the temp and mode buttons repeatedly it will start up again and then run fine until the jets are turned off then back to FLO. As a result it is not starting its normal filtration cycle on its own. The filters are quite new and clean, I replaced both capacitors and I had the pressure switch calibrated by the local pool shop. They now don't know what to suggest. Do you have any ideas what could be wrong?

is there any calcification in the system?..have you tried jumping the pressure switch (as a test) to see if code stays?
