This guide offers practical tips to help you identify and resolve typical hot tub issues, ensuring your unit functions efficiently for consistent relaxation and therapeutic use.
Common Problems with Hot Tubs
- Water Not Heating: This can result from heater malfunctions, thermostat issues, or inadequate circulation. Check the heater, verify thermostat settings, and ensure proper water flow.
