Hot Tub Repair: Helpful Hints 2
In the first article of these hints on hot tub repair, we mentioned that DIY hot tub repair can be messy or even dangerous (if electrical work is involved) for amateurs. However, a general idea about problems and likely causes can help you brief the repair person properly so that the person can come prepared and complete the job quickly.
Hot Tub Works but Water does not get adequately Heated
The problem in this case could be with the power supply, heater, thermostat or one of several others.
- Is the power supply at the required voltage, i.e. 110 volts or 220 volts as appropriate for your hot tub?
- Is the water flowing when the pump is running? It could be that an air lock is preventing water flow, which in turn cuts off power supply to the heater. You can solve the air lock problem by closing the water intake valve to the pump and then loosening the plumbing in front just enough for the air to escape. Tighten the plumbing and open the intake valve before re-energizing the pump.
- If water flow is okay, the problem could be with the heater. Switch to thermostat mode and turn thermostat clockwise to max. Check power at heater terminals. If power is okay and water sill does not heat in reasonable time, the problem is most likely with the heater element.
- It could happen that the pump does not engage with the thermostat, or the power at the heater is not correct (and you don’t really know what to do), it is best you call in a hot tub repair person who can check the contactors and other issues. The problem could be with the thermostat or the controls, best left to professionals to handle.
You should be able to provide meaningful information to the repair person even if you couldn’t solve the problem.
