How to troubleshoot Intex 28429 Bathtubs not heating properly?
- DDaniel GlennAug 19, 2025
If your Intex Bathtubs is not heating properly, first, check if the temperature is set too low and ensure the spa cover is attached. Clean or replace the filter cartridge. If the heater is in STANDBY mode, press the flame button twice to heat the water to the set temperature. If the issue persists, contact Intex Service Center.
