Spa Pressure Switch Test

If you test show 0 contnuity proceed to next step.

Spa pressure switch test.

The greater the pressure the greater the deflection. To adjust the tecmark pressure switch screw inwards to reduce the amount of pressure required and on the balboa switch screw out to reduce the gap between the button and the switch. Look at the water level in the hot tub.

If you have any continuity your meter slows some values replace pressure switch. You can also use your multi meter to test resistance of lengths of wire or cable. Most pressure switches are simply a micro switch and an air diaphragm. In most spa components resistance is good with exception to pressure switches no resistance is bad as it means that there is another path that the electricity is taking which usually means a defective component or cable and it could also pose a safety hazard where is the power loss going.

In a hot tub pressure is an easy way to determine flow rates through the pipes pump and heater. If the water level is lower than the jets the flow switch will not work. 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. Now let s find out how to test a pressure switch with a multimeter at the core a pressure switch is the same as any other switch.

With no continuity turn on power to the spa and check pressure flow switch cord again. You now should have complete continuity 1. The spa s manual will indicate how many gallons the spa will hold and how high the water level should be to function properly. 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.

Note on balboa switches you can test the switch is working correctly by pushing it upwards and if the switch is leaking or heavily corroded replace it. Generally if the pressure switch cannot be adjusted it may need to be replaced unless the problem is with the circuit board. This means that once the component a pressure switch in this case is disconnected from the main body the a c unit in this case you can test the pressure switch as you would any switch. Then measure across the 2 terminals on the pressure switch.
