The pressure switch on a hot tub or spa is a pressure sensor that is mounted onto the heater housing, or very close to the exit point of the heater.

One day, you’ll get in the spa and notice the hot tub jets don’t feel as strong as usual. It’s almost always an easy fix, so don’t worry about major problems right away. There is usually a very simple reason that your hot tub jets are a little sluggish.

A leaking spa pump is one of the most common problems spa owners face. That’s because the pump shaft is spinning around at speeds of up to 3450 rpm, generating a ton of heat and friction.

There are many reasons why your spa or hot tub may be throwing error codes, so figuring out the cause quickly is crucial.

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.

Spa pumps need to operate every day to maintain clean and hot spa water – so when your hot tub pump has problems, it’s an emergency.

Circulation pumps used in spas and hot tubs, also called circ pumps or hush pumps, are low-flow pumps that slowly circulate the water 24/7, to continuously filter, heat and chemically treat the water.
