If the water temperature in the thermowell is the same as the water temperature in the rest of the spa, the switch is damaged and needs to be replaced.
How do you fix a low flow error on a hot tub?
Option 1: Raise The Hot Tub Water Level Wait around 15-20 minutes then turn the power back on, switching on the jets and seeing if it resolves the flow error. If this clears the flow issue, you can then switch off the spa, replace the filter back then switch back on.
How do you adjust a hydraulic pressure switch?
When water flow (GPM) is sensed by the flow switch, it allows the burner to come on, heating the water. This water flow is typically activated by pulling the trigger on the gun. When the trigger is released, the water flow stops, deactivating the flow switch, and turning the burner off.Flow Switch | Pressure Washer Burner Controlhttps://www.buyhotsyparts.com › Pressure-Washer-Flow-...https://www.buyhotsyparts.com › Pressure-Washer-Flow-...Search for: How does a pressure washer flow switch work?

How to adjust pressure switch?
Many have a lock mechanism, Len Gordon has a sliding tab lock, Tecmark has a metal clip that needs to be removed or bent out of the way. Again, turn to the left to reduce required minimum pressure, and turn it to the point just beyond where the heater turns On.
How much pressure should I adjust my pressure switch?
That being said, pressure switches can be adjusted from 1-5 psi, or from 1-10 psi.
How to reset high limits on spa?
With the pump running, and the thermostat turned up, high limits reset - in short, everything ready to go, connect the wire or clips to each side or terminal, onto the brass spade connector (where the wires are connected), and within just a few short seconds, the diagnostic checks are done and the heater should turn on, or you should see an indicator light or heating code on the spa side control panel.
Why do hot tubs have a flow sensor?
It's sole purpose is to shut off the heater if low pressure (low water flow) occurs. In a hot tub, pressure is an easy way to determine flow rates through the pipes, pump and heater. Some spas also use a Flow Sensor, in addition to (or instead of) the Pressure Switch, to be sure water is flowing properly for the heater to operate safely.
How to check if a spa skimmer is working?
Look for a dirty filter, a clogged impeller, closed valve, or a piece of plastic film covering the spa drain. Check the spa skimmer water level is high enough, and the skimmer isn't sucking air. Check underneath for any drips or leaks when the system is off that may indicate an air leak when the system is on.
Do spas have safety switches?
Fortunately, spas and hot tubs are equipped with redundant safety checks - pressure switches to shut the system down when water pressure is low , and flow sensors if water flow is low and high limit sensors that are monitoring temperature.
Can you jump out a pressure switch in a spa?
Note that jumping out a pressure switch should only be done for testing purposes, do not operate a spa or hot tub with any safety components bypassed. The easiest way to jump out a spa or pool heater pressure switch is to use a short wire with two alligator clips, or other metal clips on the ends.

How to measure pressure switch?
The spa tech will start by using an ohmmeter (with the entire spa powered off) and will remove the 1 of the pressure switch wires. Then measure across the 2 terminals on the pressure switch. It should be in the open state so there would be no resistance showing up on the meter. If the switch shows a reading, it needs to be adjusted until the reading goes away (with one wire removed from switch).
What is a pressure switch in a hot tub?
Pressure switches are safety devices in a hot tub to avoid a heater dry fire or overheat condition.
When is the pressure switch closed on a Balboa heater?
Normal operating mode for a good pressure switch that is correctly adjusted is that the switch is CLOSED when the water is flowing through the heater and OPEN when the pump/heater stops. The Balboa system looks for the pump to be running when the pressure switch is CLOSED. That is when the system can heat.
Why does my pressure switch fail?
The main reason for pressure switch failure is poor water chemistry. Avoid this issue by always maintaining pH and proper water chemistry.
Why plug in original sensor?
Plug in the original sensor set to verify that there is not a connection problem.
Can you block the suction fittings in a spa?
Suction fittings inside the footwell of the spa should not be blocked. Is the pump primed and properly working? Be sure there are no air pockets such as can happen when refilling the spa with fresh water. Make sure that pesky squirrel didn't get in and start gnawin' on your wires neither.
Can a pressure switch be recalibrated?
The pressure switch may need to be recalibrated. If it cannot be recalibrated, it needs to be replaced.
