Demystifying Hot Tub Flow Errors

A hot tub flow error is like your tub’s way of saying, “Houston, we have a problem!” It signals an issue with the water flow through your hot tub’s heater. The usual suspects behind these codes are FLO, FL1, or FL2, all pointing at flow or pressure switches acting up. The culprits? A clogged filter, low water levels, air sneaking into the pipes, or a grumpy pump or sensor.

Meet the Flow and Pressure Switches

Flow and pressure switches are the unsung heroes of your hot tub. They keep a watchful eye on water flow, doubling as safety guardians. At the first whiff of trouble, they hit the emergency brake, shutting down the heater. Why? To prevent your precious heater and other vital parts from going haywire and turning your relaxation haven into a headache.

Decoding the Flow Error Codes

Here’s where things get intriguing. Flow error codes aren’t universal; they like to keep us on our toes. Manufacturers and models have their unique codes. Your instruction manual holds the keys to deciphering these cryptic messages. But for the curious minds, we’ve got some common codes:

  • FL1: The flow switch is stuck in the open position.
  • FL2: The flow switch prefers the closed position.
  • FLO: Something’s fishy with the water flow.

The Great Flow Error Hunt

Time to channel your inner detective and sleuth out those flow errors. Here’s your game plan:

  1. Water Level Check: Your tub’s water level should give the spa pillows a gentle peck when nobody’s inside. No pillows? No problem! Look for a waterline indicator within the shell or filtration skimmer. Maintaining the right water level is crucial for smooth water flow through the heater.
  2. Filter TLC: Filters are like the unsung heroes of your hot tub’s water quality. Show them some love by cleaning and soaking them overnight every ten weeks. Give ’em a weekly rinse to bid adieu to pesky debris.
  3. Filter Replacement: Even well-kept filters age. Over time, those trusty fibres wear down and become water flow gatekeepers. Plan on swapping your hot tub filter every 12-18 months. Branded filters are the way to go for efficient tub operation.
  4. Water Refill Maneuver: After a recent fill-up, ponder your hose pipe’s placement. It should be poised down the filter housing to first fill the internal pipework. An improper hose position can spell airlock trouble.
  5. Jet and Diverter Inspection: Ensure all jets and air controls are set to “on,” and diverters are in their neutral positions. Any deviations from this harmony can lead to filtration and heating woes.

Resolving Common Hot Tub Flow Errors

Now, let’s roll up those sleeves and tackle these flow errors like pros:

  1. Optimise Water Level and Filter Care: If your water level needs a boost, top up your tub until it kisses the waterline indicator. Power down, remove the filters, wait around 20 minutes (let the sensor chill), power up, and run the jets sans filters to check if the flow issue vanishes. If it does, re-install the filters. If the gremlin returns, clean or replace the filter.
  2. Banishing Airlocks: If an airlock is playing hard to get, open all jets and run the spa pumps without filters. If that doesn’t do the trick, turn off the spa, direct a hosepipe to your hot tub (ensure it flows down the filter housing), and give it another shot.
  3. Seek Professional Help: When all else fails, and the flow issue persists, it’s time to call in the experts. A faulty pump or pressure switch could be the villain. Let a technician work their magic to restore your hot tub’s zen.
