Worked great on my Balboa HS200. Had to slightly rotate the heater tube in the mounts to get clearance for this switch as this unit is larger in diameter as to the original and interferes with the motherboard.

I have a dimension one spa that’s over 20 years old, but is it still really good shape. The thermostat display was recently flashing the three lights and I tried to change the filter but that didn’t work and this fixed the problem. Make sure you drain the hot tub completely before installing the new pressure sensor.

Bought this replacement switch for CalSpa pressure switch. These tend to go out every 7 years or so, I'm on my third. When this switch goes out, either the system won't go at all with an FL error code or it will go but the heater won't come on. Either way, this switch absolutely must work right for the tub to be usable!

I have a 40 year old Teledyne Laars es250 gas heater for my hot tub. It was totally dead a few days ago. Did some simple trouble shooting and discovered that pressure switch never closed. Bought this replacement. It worked perfectly and was easy to install. Just be careful not to cross thread the plastic fitting. This switch was 1/5th the cost of the official replacement part
