1. The heater will increase the water temperature by 25°. Start with hot tap water in the clean water/formula tank—not boiling water or water heated in the microwave.
2. Check to make sure the pod is seated on the base of the unit and the power switch is turned on. The power switch is located on the pod. The heater light will not illuminate if the pod is not locked into the base correctly. Please note: there is no heated water while using the portable pod. Also, there is no switch for the heater—it will start heating once the pod is connected and it’s turned on.
3. Allow heater to warm up for about 1 minute.
4. If you’re still not getting heat, at this point it might be best to take your carpet cleaner to a technician.
