Every digital spa control is designed with some diagnostics, to self-diagnose problems with pumping and heating your spa or hot tub. Topside controls also give lots of information about your spa status, which are not to be confused with spa error codes.
There are 3 groups of error codes; Flow codes, relating to water flow, Heater codes, and Sensor codes. Let’s start at the top, today’s post is about water flow trouble codes on your spa panel. These are usually presented as FL, FLO or FLOW on your display, although it may be LF, for Low Flow, or PS for Pressure Switch.
LF, or Low Flow error codes on a spa or hot tub is really a self-preservation exercise for your hot tub. When water isn’t flowing fast enough through the heater, the FLO error code shuts things down, to avoid a total meltdown (well, not really a melt-down, but you know).
Flow problems are the number one source of trouble for the spa or hot tub owner. When the water isn’t flowing like it should, the heater stops working, equipment overheats and water quality quickly suffers.
So – FLOW. very important. Here’s what to do if your spa throws a FL, FLO or FLOW error code at you.
For Low Flow spa error codes, check the filter, check the pump and check the valves to find something that is obstructing the water flow. Could be a dirty filter, a clogged impeller, closed valve, or a piece of plastic film covering the spa drain. Could also be low water level. Sometimes, it’s actually a bad pressure switch or flow switch, or loose connections or damaged wires or wire connectors.
Proceed step by step, and you should be able to find the cause of the FL, FLO or FLOW error code. If you need assistance with spa trouble codes, you can call us anytime at 800-770-0292
