Question about Pool & Spa
I have a 2004 Reflections Spa that will not heat when I run the diagonistics test I get the HC code which according to the manual is replace Heater. I've replaced the following and still no heat (Heater, Pressure Switch, Filter,High limit sensor, and Water Tempature Sensor) So now I'm at loss. The Tub works as it should just won't heat (all jets and lights work). The display is flashing and acting like its trying to heat but it doesn't and gets really cold here in the Midwest. Any one with ideas please let me know or a recommended repairman that will service the south suburbs of Chicago. Happy New Year!
Take a Multimeter and measure the voltage at the heater element. If it is getting voltage either 120v or 240v depending on the voltage to the spa, you've got a bad heating element

Heater contactors "buzzing": Do you mean normal buzzing or extra loud buzzing? Loud buzzing or chattering can be caused by low voltage to a contactor. If normal sounds, then probably the relays on the contactors is working, but the contacts may be stuck, or burned enough so as not to make contact. First, get a voltmeter and check for 240 volts AC at the heater contactor terminals. If the voltage is low, most likely you need to check the contactors further. Check for dirty contacts, clean if needed. If the contacts are not moving when energized, then you will probably need to replace one or both of the contactors.

I had the same problem. The water sensor is on a pipe running into your pump. It will have a circular clamp around it. Remove the clamp and pull the sensor out of the pipe. The wires should run into your control box. disconnect the wires and replace. My water sensor was part 7790. Not sure if you have the same one. Do an online search. bestbuypoolsupply.com has them for $50 plus 9 for shippng. Hope this helps.

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.
