A recent service call involved a spa that hadn’t been operational for several months. Upon restarting, the spa displayed an “Error 2” and ceased functioning, a symptom typically indicative of a faulty temperature sensor. After eliminating other common issues through thorough testing, the diagnosis was confirmed: the sensor needed replacement.
The repair revealed the old sensor had severely corroded to the extent of breaking into two pieces. A new sensor was installed, and after rigorous testing, the spa was back to its optimal condition. The customer was pleased with the restoration, although there was a bit of maintenance left to do. To ensure long-term cleanliness and function, running a pipe degreaser through the system was recommended to deep clean the pipework.
