Did you know that low water flow through the heater chamber is the #1 problem for the hot tub to stop heating?

Often the problem is a maintenance issue and easily solved by assessing one of three things:

  1. Low Water Level – Colder temperatures increases water loss due evaporation during use or condensation dripping from tub cover around the outside of the tub
  2. Dirty Filter – Reduced flow of water though the filter perhaps due to more use of creams on your skin in the dry weather or extra users from entertaining
  3. READY or REST Mode for heating

READY: Changing to READY mode in the colder months ensures the tub will heat between your programmed FILTER cycles to maintain your desired water temperature and ready for use anytime you are.

REST: Often users may be in REST mode during the summer months when the water temperature is supplemented by warmer air temperatures and sunshine; the tub only heats during your programmed FILTER cycle to reach your desired water temperature. The water will cool between the filter cycles and not always be ready for use at the desired water temperature. If the user uses the tub the same time every day, the user can consider changing their filter cycle to match their usage time to stay in this mode.

When flow is the issue, the hot tub will display error codes such as HTR FLOW LOSS or FLO for example.

Tips for staying in hot water in winter:

  • To fill your tub, keep a garden hose handy. Keep it in a heated area or fully drain your hose between top-ups to eliminate ice plugs in the tubing.

  • Keep an extra filter/filter set on hand for an easy change out when flow is restricted; this helps to reduce downtime with the tub.

  • When removing your filters from the tub aways first put your tub to SOAK. This function will stop all pumps from running and allow you to take the time to look down in the filter compartment for any wind-blown debris to be removed before re-installing a cleaned filter.
