F05: Pump Blocked or pressure switch empty not reached
- Check efficiency of J9 connector on card, verifying a voltage of 220V between pins 8 and 9
- Check that pump if being fed
- Check Pump Filter + wall drain
- Change Pump
- Replace Card
You have 220v running into your motor, the red and the plack are in most cases the same 110v line and what your calling a white netural is a common line. In other words the second half of your 220v line. If your red and black are the two opposing 110v lines that make up your 220v and they are put on the motor and turned on they short aginst each other and blow the breaker. One of your 220v lines should come into your hi -low switch and then split to your high and low on the pump. The other half of your 220v line will go to the common or what your calling nuteral. The difference is a netural completes a 110v circut and a common completes the 220v circut it will take to run the motor. One of the splits will complete the low speed circut and the other will complete the high speed circut. You need to check your voltage comming into the spa, the way the spa is wired (110v-220v), and how the motor is wired (110v-220v). For your spa this will be in your owners manuel or on a scematic inside a panel or door and is quite often a plug you change from one spot to another. On your motor will have a scematic on the back of the motor that will tell you haw to adjust the wireing already in place on the wire board of the motor. This may sound deep but if all your voltages are set the same and your high and low are the same leg of power, this should fix your problem.
